Effect of Prior Aging on Fatigue Behavior of IM7/BMI 5250-4 Composite at 191-C
IM7/BMI 5250-4 with carbon fiber orientations and [0/90] were aged in air at 191-C for up to 1000 hours. The weight loss was analyzed during the aging process. Tension to failure tests were performed on both the unaged and aged specimens to establish a baseline for the Ultimate Tensile Strengths and Young's Modulus. Tension-tension cyclic load fatigue testing was conducted on the specimen to determine the effect of prior aging on the fatigue response of the composite. Cyclic strain accumulation was not influenced by prior aging, but it was influenced by the stress levels applied. Specimens lost 0.2% more weight than the [0/90] specimens from aging in air.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Nanotechnology
Numerous technological changes have taken place in the last 50 years; many of them were considered science fiction in the twentieth century. Geoffrey Hunt and Michael Mehta said nanotechnologies are making the jump from science fiction to science reality.1 Popular science fiction author Michael Crichton has written two best seller novels that include a discussion of nanotechnology and future possibilities. Nanotechnology is actually a family of nanoscale technologies and is a swiftly rising field whose dynamics and forecast pose many challenges not only to scientists and engineers but also to society at large. This Nanotechnology covers a broad assortment of procedures and uses that will make some products better, cheaper, and faster, and it will enable the creation of products and applications that are currently beyond our ability to envision. Although many have called nanotechnology the next industrial revolution, much research needs to be done to ensure the future safety of the world and the human race due to the use of this revolutionary technology at the nanoscale.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Saved by Iridium? An Alternative to GPS
The Department of Defense (DoD) has depended on different space-based assets as critical components to battlefield operations. As technology has evolved, space-based assets have become the eyes and ears of the military. Unfortunately, these assets have become one of the most vulnerable U.S. infrastructures. In 1995, the U.S. Global Positioning System (GPS), a complex and sophisticated space-based asset, became fully operational, providing accurate, reliable, and secure information on position, navigation, and timing to the joint force. The joint force uses GPS navigation to locate objectives and coordinate movement of ground forces and supplies. In addition, cruise missiles, smart bombs, and artillery projectiles currently use GPS to guide them to enemy target coordinates. GPS also provides a timing element that has become critical for the military in communications, computer networks, combat planes, and Unmanned Aerial Vehicles. Space-based technologies reach down into everyday military activity, so interrupting service immediately degrades operations. GPS capabilities are great and adversaries may be quick to deny or degrade them. Currently, there is not an alternative to GPS for ground, air, sea, or space operations. The methods of operating with a degradation or loss of GPS are contingent on the type of operation, whether it is land, sea, air, or space; as the current backup alternatives to GPS can only support one operation at the time. For this reason, it is critical for the joint force to have at least one backup alternative. At this time, the only alternative appears to be space-based, as a space-based alternative can provide simultaneous global coverage more affordably and accurately on PNT to the entire joint force. The most feasible potential space-based alternative to GPS is the existing commercial Iridium system, a sixty-six satellite communication constellation in low-earth orbit, under a program known as the high integrity GPS or iGPS.

Development of a Pilot Candidate Selection Model Using Multivariate Techniques
Every year the Air Force spends millions of dollars to send personnel through Undergraduate Pilot Training (UPT). To be accepted into UPT, a candidate must go through a selection process to ensure the Air Force is choosing personnel best suited to succeed in the rigorous training environment. One of the key factors provided to the selection board is the Pilot Candidate Selection Method (PCSM) score. The PCSM weights a candidate's Air Force Officer Qualification Test (AFOQT) score, Federal Aviation Administration (FAA) flying hours, and a Basic Attributes Test (BAT) score to provide a single score between 1 and 99. The goal of this study was to apply a full range of multivariate data analysis techniques as well as current pattern recognition practices to the provided data to determine an appropriate model to predict pilot success. The new model was validated to establish its predictive accuracy, capabilities, and limits. In order to avoid bias, the model development process did not make any comparisons to the current PCSM model. However, a post-development comparison was made to determine relative model performance. The performance of the new model was superior to the existing model. The difference in performance between the two models is shown to be statistically and practically significant.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Geolocation of an Audio Source in a Multipath Environment Using Time-of-Arrival
The Air Force and the Department of Defense (DoD) are continually searching for ways to protect U.S. forces, both stateside and abroad. One continuing threat, especially in the current world environment, is gunfire from an unseen sniper. Designated areas, such as a forward deployed base or motorcade route, need to be continuously monitored for sniper fire. Once detected, these gunmen need to be located in real time. One possible method for accomplishing this task is to geolocate the audio signals generated using time-of-arrival (TOA) algorithms. These algorithms rely on direct-path measurements for accuracy. Multipath environments therefore pose a problem when measuring signals from the audio spectrum. The errors induced by a multipath environment can be reduced by introducing additional audio receivers to the detection system. By sampling all possible combinations of a minimum set of receivers (four), a more accurate location can be calculated. An accuracy of six meters can be achieved roughly 69 percent of the time, though most of the error occurs in the vertical component. An accuracy of six meters in the X/Y plane can be achieved approximately 97 percent of the time.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

The New Intelligence, Surveillance, and Reconnaissance Cockpit
The purpose of this paper is to examine how unmanned Intelligence, Surveillance, and Reconnaissance capabilities must change in order to meet the long term requirements of U.S. war-fighters. Contemporary non-strike capable Unmanned Aerial Vehicles and strike capable Unmanned Combat Aerial Vehicles (UCAVs) cannot match the speed and payload capacity of modern manned platforms; however there are significant changes on the horizon. This research paper addresses this subject using the evaluation methodology, analyzing five areas necessary for continued Unmanned Aircraft System (UAS) progress: UAS force structure, persistent coverage, asset sensor packages, improved lethality, and stealth developments. While this paper emphasizes continued developments in unmanned capabilities, the first step that must take place in the development process is the minimization of procurement and employment duplicative efforts. For example, the U.S. Army and U.S. Air Force currently have similar yet separate UCAV programs, and both continue to research the development of comparable capabilities to meet war-fighter needs. The introduction of an UAS Executive Agent will allow the U.S. military to focus on UAS design improvements, and will also contribute to necessary changes in emerging UAS programs. With an established joint interdependence, the Department of Defense (DoD) can then fully pursue new technological advances in unmanned capabilities - persistence, modular sensors, lethality, and stealth. Critical UAS research could potentially lead to the development of long endurance, low observable assets capable of fulfilling multiple war-fighter collection requirements, while providing a more robust strike capacity. By focusing on these elements, the DoD can create a more capable and lethal unmanned capacity to meet current and emerging war-fighter needs, through evolutionary and revolutionary research and development.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Improving Air Mobility Command's Aircraft Maintenance Recovery Team Process
Given the significance of Air Mobility Command's role in rapid global mobility, not just for the Air Force but for the entire DoD, the U.S. cannot afford to lose any of its strategic airlift capability. For research purposes this paper narrowly defines lost strategic airlift capability as any of the two aircraft comprising AMC's strategic airlift fleet - namely the C-5 Galaxy and the C-17 Globemaster III - broken away from their station of assignment. To repair these aircraft when broken in'the system', AMC currently utilizes a dedicated system of command and control, people, parts, and equipment, some of which is pre-positioned and some available on an as-needed basis. Known broadly as the Maintenance Recovery Team (MRT) process, the system emphasizes identifying, troubleshooting, and fixing broken aircraft as quickly as possible to maximize strategic airlift availability to DoD and other airlift customers. With this in mind, this paper will discuss AMC's strategic airlift role, identify AMC's MRT process, analyze AMC's historical MRT data for specific improvement opportunities, and, where possible, recommend improvements leading to an increase in the efficiency of AMC's MRT process.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Penetrating the Ion Curtain
Since the first laser was developed in 1960, directed energy technologies have captured the imagination of civilian and military communities worldwide. Over the past four and a half decades, increases in power, quality and laser types have set the foundation for directed energy weapons (DEWs) to enter, then dominate, battlefield engagements. Given this hypothesized future, the scientific and operational communities need to address the implications of fielded DEWs at the tactical and strategic levels. The following paper addresses the question "Can aircraft survive against a Directed Energy Integrated Air Defense System (DE-IADS)?" This paper will use trend analysis to uncover the expected DEW capabilities in the 2030 timeframe. Trend data will then provide the foundation for a scenario analysis that compares three distinct scenarios. Scenario 1 juxtaposes an advanced conventional USAF strike force against a DE-IADS. Using the same backdrop, Scenario 2 pits a directed energy-equipped USAF strike force against the same DE-IADS. And lastly, Scenario 3 evaluates a directed energy equipped USAF strike force against an advanced, but conventional, IADS. The results will show that DE equipped systems alone, do not provide the necessary fire power required to achieve victory or prevent defeat. Only with a smart combination of DE and advanced conventional capabilities (such as hypersonic munitions) can one side bring enough combat power to dominate an opponent.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Determination of the Constitutive Equations for 1080 Steel and VascoMax 300
The objective of this research is to establish a better representation of the components utilized in a gouging event being considered in research leading to a better understanding of the Holloman High Speed Test Track. Gouging occurs when two metals are traveling at a slight incline to each other at velocities nearing 1.5 kilometers per second, and results in a structural failure of both the metals. The gouging process occurs at very high strain rates, which results in non-linear stress-strain relations. The coefficients that lead to the Johnson-Cook equations have been determined by the Split Hopkinson Bar test for 1080 steel and VascoMax 300. The Split Hopkinson Bar test was conducted using various strain rates and temperatures to produce meaningful stress-strain relations for both of the steels. These relations allowed a fit of the data to yield specific material coefficients defined in the Johnson-Cook constitutive model. Both the 1080 steel and Vascomax 300 models showed excellent approximation of the plastic region. Verification of the constitutive models was conducted through the use of Taylor tests. A Taylor test model utilizing the constitutive equations was developed in CTH and produced deformation profiles that closely resembled specimens taken from experimental Taylor tests. The end result of this work will be utilized in further studies toward overall high energy impact evaluation.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Space Operations
America's capability to operate in space is increasing with every passing day. Space operations are already recognized as a crucial part of all American military operations. Military space operations may be indirect, through such staples as navigation, communications, and surveillance/reconnaissance support to the war fighter, or direct, through development and fielding of a range of responsive directed energy and kinetic energy weapons. A modest fleet of flexible, mission-tailored transatmospheric vehicles (TAVs) has an important place in any thoughtful space operations architecture, providing the only conceivable way to insert human presence rapidly into the fast-breaking crises of 2025.

Determining Logistics Ground Support Manpower Requirements for a Reusable Military Launch Vehicle
Successful space-based technologies like satellite imagery and GPS have increased military demand for a rapid-response launch capability. AF Space Command's Operationally Responsive Spacelift program was developed to ensure that the AF has the capability to launch a payload into orbit within hours of a tasking notification, and requires development of a new space launch vehicle. The Reusable Military Launch Vehicle (RMLV) is currently in the design phase. The AF Research Laboratory sponsored development of the MILEPOST simulation model in order to assess the turnaround time, and thus responsiveness, of various design alternatives. The focus of this thesis is to improve the fidelity of the MILEPOST model by assessing the logistics manpower required to support the modeled turnaround activities. The research determined the appropriate AF organizational structure and manpower requirements for RMLV ground support agencies based on the activities modeled in MILEPOST. This information will be incorporated into the model in future research efforts, resulting in the capability to evaluate RMLV design alternatives based on both turnaround time and workforce requirements.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Expendable Remotely Piloted Vehicles for Strategic Offensive Airpower Roles
Major Larm examines the feasibility of developing expendable remotely piloted vehicles (RPV) and explores future concepts of conventional US offensive airpower roles. He outlines the historical base of the larger category of unmanned aerial vehicles. Major Larm does not propose to take the pilot out of the cockpit, but he examines the concept of taking the cockpit out of the aircraft. By incorporating the added dimension of employing one-use vehicles to this concept, he attempts to reveal representative-though not all-encompassing-innovative airpower ideas. Major Larm's conclusion is that the use of expendable RPVs for strategic offensive airpower roles is a viable concept.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Going Deep
Finding deeply buried facilities stands out as one of the toughest technical challenges in the Air Force's efforts to find, fix, target, track, engage and assess targets of interest anywhere on earth. Nations have located potential high-value, high-interest targets such as weapons of mass destruction (WMD), WMD manufacturing plants and storage areas, missile garrisons, fuel storage areas and command and control nodes underground. This paper will focus on the development and application of gravity field sensors for deeply buried target detection. It will begin with an explanation of what deeply buried facilities are and how their construction and use has evolved over the years. Next, the discussion will look at the weapons available today to counter deeply buried facilities and the intelligence information needed to make these weapons effective. The information needed to properly target these weapons will directly influence the capability of the sensors needed to detect and characterize deeply buried facilities. The focus of the paper will then shift to intelligence sources, starting with the intelligence capabilities available today and the ability of a potential enemy to counter those intelligence assets, then shift to exploring intelligence sources not in use today and their potential application in the hunt for deeply buried facilities. Finally, this paper will investigate gravity measurement technology to address the problem of deeply buried facility detection and characterization.

Gaseous Continuous Emission Monitoring Systems
The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Preventing a Cyber Dresden
World Wars I and II witnessed air power's development in the crucible of hostilities. Ambiguous and competing air power schools of thought, on occasion, resulted in the strategically questionable employment of air power. The Allies' bombing of the cultural city of Dresden in February 1945 serves as a vivid instance of the results of these tensions. The firestorms that devastated Dresden now inflame the contemporary air power debate: was the area bombing of Dresden proportionate to the commensurate military gains? Striking similarities exist between the emergence of cyber power today, as a means of warfare in a new domain, and the development of air power in the first half of the twentieth century. Reflection upon air power's evolution has been employed as a guide for the more efficient and effective development of cyber power. An analysis of air power's formative years has highlighted many of the pitfalls that lie hidden on cyber power's developmental path. An awareness of these pitfalls will allow cyber power to develop pre-emptive strategies on how best to avoid them; thus, debates pertaining to a cyber Dresden will be able to take place before, rather than after, the event. Learning from air power's early experiences will help prevent cyber power from becoming mired in the same pits that frustrated air power's development. In turn, cyber advocates will be better able to concentrate their focus upon developing a coherent theory of cyber power, uniquely tailored to the challenges of their own domain.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Thermal Characteristics of Pitch Based Carbon Foam and Phase Change Materials
Phase-change thermal energy storage devices offer thermal control systems an option that allows a smaller heat sink to be used by absorbing the thermal energy quickly and storing it in the phase change to prevent failure of electronic components and then slowly releasing the heat to the heat sink. This paper experimentally determined the transient response of carbon foam with a phase-change material by measuring the response to a step temperature input to test samples. The transient response was recorded until steady state was reached. An analytic response was created and compared against the measured response. A simplified analytic prediction of the transient response was developed by using an energy balance. This approximation was then compared against the experimental results.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Upon This Rock
The use of space permeates all aspects of the American way of life. If the U.S. is to protect its space capabilities, it must increase its space situational awareness (SSA) to provide the foundation for activities in space. In the year 2030, congestion will describe the space environment. Space debris will be abundant, and satellite size will diminish through technology proliferation. The Air Force, as the Executive Agent for Space, will need to diagnose and attribute space events to meet this threat; however, current radar and optical telescopes cannot resolve these small objects.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Developing a Predictive Model for Unscheduled Maintenance Requirements on United States Air Force Installations
The United States Air Force Civil Engineer community continually strives for more descriptive methods to explain the impact of funding decisions on future infrastructure conditions. This paper develops one such method by using linear regression and time series analysis to develop a predictive model to forecast future year man-hour and funding requirements for unscheduled maintenance. The results provide predictive models for up to a 5 year forecast with improved results for a 3 year outlook and routine maintenance calls.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Stunning Swarms
This paper proposes and advocates the concept of Micro-Air Vehicle Incapacitating Swarms (MAVIS) as an effective non-lethal capability for irregular warfare as well as other spectrum-of-warfare applications. The intent of MAVIS is to provide an alternative to the conventional USAF arsenal that typically produces unacceptable collateral damage in the COIN/IW (counter-insurgency/irregular warfare) fight. Collateral damage has proven counterproductive to winning the hearts and minds of the populace afflicted with the cancer of insurgency/terrorism. Due to the difficulty in determining the exact targets in a dynamic urban environment or in any situation with imperfect intelligence, MAVIS will be used in an "area attack" fashion to administer metered doses of medication to subdue combatants as well as nearby civilians. Rendered unconscious from the fast-acting and long-lasting medication, the insurgents/terrorists will be removed from the populace while sedated, processed to gather intelligence, and permanently separated from the people. MAVIS will deny insurgents/terrorists their cherished martyrdom, allowing the threatened government to process them as it sees fit.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Moderate Course for USAF UAV Development
USAF unmanned aerial vehicle (UAV) advocacy from 1980 to date has swung from an apparent disinterest in UAV systems to an aggressive acceptance of UAVs to solve mission needs. However, continued UAV programmatic setbacks indicate an appropriate UAV course for the Air Force remains to be charted. Tactical UAV programs between 1980 and the early 1990s conspicuously lacked USAF involvement and demonstrated a sub-par evolution of UAV capabilities, technology, and development. However, spurred by concern over mission loss to sister services, USAF demonstrated a mid-1990s new found interest in UAVs despite the less-than-proven performance of previous UAV systems. USAF UAV acceptance was embodied in four UAV end states and two High Altitude Endurance (HAE) UAVs. However, continued setbacks with HAE UAV programs soon impacted USAF's ability to meet UAV end state timelines as well as USAF commitment to UAV funding. HAE UAV miscues indicate the USAF UAV course charted after its mid-1990s UAV acceptance was founded on unproven technology. Consequently, this paper recommends a moderate USAF UAV course founded on proven technology and conservative investment. This moderate UAV course is enabled by a `wait and see' approach with the ongoing HAE UAV Advanced Concept Technology Demonstration (ACTD). The `wait and see' approach commits minimal USAF funds to HAE UAVs pending successful HAE UAV technology demonstration.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Building a True Air and Space Operations Center
"The role of space in American military operations has evolved significantly since the end of the Cold War with the theater Air and Space Operations Center (AOC) playing a major role in integrating space effects into theater warfare. Moving far beyond traditional support roles, space operations in the AOC now include the defense of friendly space capabilities from interference and attack; the offensive ability to disrupt or deny an adversary the use of space; and coordination of theater space operations. However, the organization of space operations in the AOC has not kept pace with these changes. The primary assertion in this study is that the AOC needs to reorganize space personnel in the AOC and build a robust space organization to meet the Joint Force Air Component Commander's (JFACC) expanding space responsibilities. This will help resolve ambiguities and shortfalls in the current organization of space personnel that hinder the execution of these responsibilities. Today, the Air Force is on the threshold of building a true Air and Space Operations Center that can deliver air and space effects in support of air, land, maritime, and special operations forces. While there is no perfect organizational structure, the adoption of a Space Specialty Team or Space Division construct in the AOC can improve the JFACC's ability to execute his air and space war fighting responsibilities in support of the Joint Force Commander's objectives."--Abstract from web site.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

An Evaluation of a Networked Radiation Detection System
First responders assess a Nuclear/Radiological (NUCRAD) event in a timely and accurate manner by creating a site characterization that reflects the location of various levels of contamination based on their instruments' readings. The survey team experiences difficulty in accurately recording this critical data due to the challenge of operating multiple devices and communicating the devices' readings to other survey members. First responders produce a representation of the contamination or activity on a map that contain rings outlining the levels of activity and/or single locations of a single activity. Recently, several agencies began creating software programs that record a first responder's instrument readings, time, and the global positioning system (GPS) location plotting the information in real-time. The Environmental Protection Agency (EPA) Region 5 developed the Rapid Assessment Tool (RAT). This research evaluates the effectiveness of RAT by comparing the timeliness and accuracy of the site characterization created by multiple survey teams (one team not using RAT and another team using RAT). All of the Bioenvironmental Engineer (BEE) Survey Teams using RAT decreased their survey times for all scenarios. The Weapons of Mass Destruction - Civil Support Team (WMD-CST) survey teams using RAT decreased their survey times during the lane, bounce and bypass, star, and cloverleaf scenarios. However, survey times increased for the zigzag and radial scenarios.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Relevance
Operation DESERT STORM led to the awareness that space assets could be instrumental at the operational, tactical, and strategic levels of war. Air Force Chief of Staff, General Merrill McPeak has been widely quoted as calling DESERT STORM the "first space war"1. The use of Space during Operation DESERT STORM left commanders asking, how do I effectively employed space in concert with combat operations, and who are my Space experts? The United States Air Force permanently assigns space professionals to regional Commands, operational wings, and even tactical squadrons to integrate space and its effects. This ensures space is taught and implemented during routine training as well as combat operations to ensure forces "train as they fight". The Air Force Weapons School (USAFWS) provides graduate-level instructor courses that provide the world's most advanced training in weapons and tactics employment to officers of the combat air forces. Airmen attending the USAFWS are recognized experts in their system. While attending the USAFWS, they are immersed in all aspects of their weapon system and graduate as system experts. Space graduates of the USAFWS, Space Weapons Officers (SWOs), are immersed in the "full spectrum" of Space. This training results in a graduate who is a space "generalists" rather than a system specific expert.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Electromagnetic Pulse
This research provides evidence that preemptive employment of an electromagnetic pulse device by a rogue state over US pre-positioned forces could have deleterious effects on US first-strike capability, resulting in decreased US regional combat power while degrading, delaying, and possibly deterring further US action. Additionally, it presents a series of measures for preventing, preparing for, and protecting US deployed forces against an asymmetric electromagnetic pulse (EMP) threat. While the United States remains the sole conventional military superpower in the World, potential adversaries will seek ways to counter her dominance. The preemptive use of an electromagnetic pulse weapon over pre-deployed US forces is capable of silencing, permanently degrading, or destroying sensitive electronics prevalent in modern US military hardware. Current neglect of nuclear hardening practices, acquisition of electronically sensitive commercial-off-the-shelf components for US military hardware, and the lack of a firm US EMP retaliation policy make nuclear EMP a particularly attractive weapon-of-choice. This research concludes that the potential impacts to US pre-deployed forces from a preemptive EMP attack would be unacceptable; ultimately degrading, delaying, and possibly deterring the United States from further action against the offending nation. Furthermore, the US military can no longer remain reactive to the threat of EMP attack; instead it must adopt a proactive program of prevention, protection, and policy for her military forces. Through selective shielding of tactical systems, hardness assuredness programs, organic missile defense, and a concrete policy for US response, the United States can better guarantee the survival and combat effectiveness of her deployed military.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Future Air Force Operations in Cyberspace
"The United States Air Force is poised to make another technological and strategic leap that has marked its short and storied history. The delivery of payloads of consequence over strategic distance is a hallmark of the Air Force contribution to national defense. Over the last sixty years the threats have changed and the Air Force has combined ideas, technology, and doctrine to produce effects, relevant to their era, that give the President an enduring suite of capabilities to the nation. The emergence of cyberspace as a recognized domain is the latest in a series of technology based mission sets dating back to the beginning of air power. Three cases have emerged and endured over the last 60 years. The 1930s and 1940s were years of strategic bombing. For the first several years of World War II, the only direct action against Nazi Germany was the strategic bomber. The strategic nature of the bomber and missile forces delivering nuclear payloads dominated the 1950s and 1960s. The 1980s and 1990s saw the Air Force recognize that a new operational domain and the enabling technology were emerging in space. Technology now enables precision strike and expeditionary operations as a timely projection of power that enables rapid response and immediately available strategic options. Cyberspace operations are in the idea phase right now. The pace of change and advancement in technology is such that it is impractical and imprudent to wait to determine cyberspaces military implications. Regardless of the outcome, the Air Force has made the first move amongst the services in raising cyberspace operations to the status of operational domain and establishing itself once again as the leader in developing new capabilities and effects relevant to current strategic threats and concerns."--Abstract from web site.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

The Oxidation Kinetics of Continuous Carbon Fibers in a Cracked Ceramic Matrix Composite
Experimental observations and results suggest two primary regimes as a function of temperature, i.e., diffusion and reaction controlled kinetics. Thermogravimetric analysis of carbon fiber in flowing oxygen gave an activation energy of 64.1 kJ/mol in the temperature range of 500 to 600 C and an apparent activation energy of 7.6 kJ/mol for temperatures from 600 to 1400 C. When C/SiC composite material was unstressed, matrix effects at temperatures from 900 to 1400 C protected the internal fibers. When under stress, self-protection was not observed. Increasing the stress from 10 to 25 ksi caused a 67 to 82 percent reduction in times to failure at temperatures from 750 to 1500 C. Based on experimental results, observation, and theory, a finite difference model was developed, which simulates the diffusion of oxygen into a matrix crack that is bridged by carbon fibers. The model allows the influence of important variables on oxidation kinetics to be studied systematically, i.e., temperature, reaction rate constant, diffusion coefficient, environment, and sample geometry.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Presentation of AFCYBER Forces
The future Air Force as part of the Joint Force, in close coordination with multi-national, interagency, and non-government partners, will operate in a complex and uncertain global security environment in which adversaries will seek to apply asymmetric threats to perceived vulnerabilities. International organizations, nation states, rogue states and terrorist organizations are prominent actors in this environment. Taken together, these have led to a shift in the characteristics of joint warfare and crisis resolution. By extension, the Air Force and Joint Force's role in this security environment have changed, especially with regards to cyberspace.2 In 2003, the President of the United States published the National Strategy to Secure Cyberspace as a first step in recognizing the importance of cyberspace to the United States nation interests. As noted in this document, "The way business is transacted, government operates, and national defense is conducted have changed. These activities now rely on an interdependent network of information technology infrastructure called cyberspace. The policy of the Untied States is to protect against the debilitating disruption of information system operations for critical infrastructure and, thereby help to protect the people, economy, and national security of the United States."This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Unmanned Horizons
The one and only shot the US had against Osama bin Laden was all down to a new surveillance aircraft the CIA was still testing and evaluating at the time. Commanders decided putting the small unmanned drone, what was then called a UAV, through a little 'real world' experience might be interesting. The shot was not taken due to a mix of domestic political and diplomatic reasons. Indeed one problem was that the closest 'shooter' or USAF fighter would have had to violate allied airspace unannounced - a tough ask during an unstable nuclear stand-off between Pakistan and India.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

7th Army Landwarnet Training and Readiness Oversight
The Army network in Europe or 7th Army LandWarNet (7th Army LWN) is the nexus where an industrial age military command and organizational apparatus collides with an information age system. The Army network in Europe is no longer aligned with the command authorities which define the training and readiness oversight (TRO) of the network or the organizational structure and functions which are responsible for the execution of network TRO. Disconnects between the authority and organizational components of network TRO and the network require synthesis through a holistic view of command authority, organizational structure and functions and the network. Failure to correct these disconnects means the planning and execution of network TRO will continue in a piecemeal, uncoordinated and unsynchronized fashion. Network TRO must be coordinated and synchronized across the entire network- "end-to-end".This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Non-Lethal Weaponry
Consideration of non-lethality and non-lethal weapons by the Department of Defense as an expression of military power is a relatively new yet growing phenomenon. This report explores four issues germane to non-lethal concepts and technologies in the DOD and makes recommendations derived from those issues concerning the integration of non-lethal weaponry into future United States military operations. The approach taken in the research centers on a modified content analysis of unclassified materials published between 1990 and 1997 related to non-lethality and non-lethal weapons. The genesis of non-lethality in the DOD has been convoluted, involving multiple actors struggling over the definition of non-lethality along with scattered operational experiences and the erratic development of policies and technologies. Four motives now drive DOD non-lethality: A changing threat; the need for more response options; the desire to reduce lethality, and force protection. Non-lethality scenarios span the spectrum of conflict and the traditional levels of war, while the suitability criteria for non-lethals include technical feasibility, operational utility, policy acceptability and safety. Coherent, substantiated, decisive and appropriate actions must be taken to ensure the transformation of non-lethality into an integrated component of US armed capability. These efforts require a multitude of actors engaged in policymaking, legislative, doctrinal, architectural and acquisition initiatives drawn from the history, motives, scenarios and criteria associated with non-lethality in the Department of Defense.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

USAF Aircraft Maintenance Management
Aircraft maintenance performance has steadily declined since the Objective Wing organizational structure was implemented for the Tactical Air Forces (TAF). Is the Objective Wing the right organizational structure for aircraft maintenance? USAF maintenance management philosophies have changed numerous times. Over the past 50 years, the Air Force searched for an organization that maximized efficiency and performance. Reorganization has been the preferred method of gaining efficiency or performance. The focus of this research is to analyze past organizational structures to define key elements that affect maintenance performance and develop an organization that will improve maintenance performance. The research method is a historical analysis of tactical aircraft maintenance organizations in the USAF. The researcher found that there are three key elements that affect the organizational structure and its subsequent performance. Those elements are context, culture, and strategy. A maintenance organizational structure must be based on these enduring elements to succeed. A matrix organizational structure based on our current and expected context, culture, and strategy is proposed.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Combined Arm Battalion and AirLand Battle
This monograph addresses how combined arms organizations should be formed in our Army today. Specifically, it focuses on the question, "what arms, if any, should be combined organically at battalion level?" This issue is important because our AirLand Battle doctrine considers combined arms to be essential to winning on the modern battlefield. Therefore, we should investigate the best means by which to maximize the potential of the organizations. The monograph first examines the theoretical foundation for combined arms. Next, both historical and contemporary evidence are examined to derive a set of criteria that can be used to analyze the four selected arms: infantry, armor, artillery, and engineer in terms of the AirLand battlefield environment. The five selected criteria are frequency of interaction, competence of commander to synchronize the effects of weapon systems, scarcity of resources, cope of tactical missions, and similarity in range and mobility. These criteria are key factors that should be used whenever determining how an organization should be structured organically. Conclusions concerning the structure of a combined arms battalion are drawn from an analysis of these dominant criteria. This monograph concludes that infantry and armor are the only two arms that should be combined organically at battalion level. By combining these two arms permanently, it is almost certain that the combat potential of the organizations will increase.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Dissolution of Chromium From Inhalable Primer Paint Particles Into a Simulated Lung Fluid
The use of chromate as a corrosion inhibitor in primer paint is an essential component for the protection of aluminum-skinned aircraft and the primary source of hexavalent chromium (Cr (VI)) exposure to USAF aircraft painters. The objective of this research was to quantify the dissolution of chromate from freshly sprayed paint particles into a simulated lung fluid (SLF). Two primer paints were sprayed with a paint spray gun to generate overspray particles for collection into impingers filled with SLF. Particles were allowed to soak in SLF for 24 and 48 hours and then the particles were removed by centrifugation. The remaining Cr (VI) dissolved in the SLF was then compared to the initial Cr (VI) concentration with particles. The results indicate that the dissolution of Cr (VI) into SLF is hindered by the paint. Also, the results indicate that the amount of Cr (VI) dissolved into SLF from the paint particles is not significantly different between the two paints tested or between the 24- and 48-hour resident times. This study suggests that Cr (VI) in paint particles is less bioavailable than Cr (VI) in other particles such as dust or mist.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Space Force 2020
Because of world events and legislation like Goldwater-Nichols, Air Force roles and missions continue to change, and do so under great scrutiny. In particular, military space issues have assumed even greater importance following recognition of the Persian Gulf War as "the first space war," and with the November 1996 release of the Air Force's latest White Paper, Global Engagement: A Vision for the 21st Century Air Force. This white paper included the most important USAF statement ever concerning the role of space in the future of the Air Force: "We are now transitioning from an air force into an air and space force on an evolutionary path to a space and air force." But beyond the overall direction this strategic vision provides, the Air Force does not have a clear and supportable interpretation or definition of future Air Force space operations or "uniformed" space operators. This research paper attempts to provide that interpretation and to further expand the awareness and understanding of Air Force core competencies and mission areas as they relate to space operations.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Geolocation of an Audio Source in a Multipath Environment Using Time-of-Arrival
The Air Force and the Department of Defense (DoD) are continually searching for ways to protect U.S. forces, both stateside and abroad. One continuing threat, especially in the current world environment, is gunfire from an unseen sniper. Designated areas, such as a forward deployed base or motorcade route, need to be continuously monitored for sniper fire. Once detected, these gunmen need to be located in real time. One possible method for accomplishing this task is to geolocate the audio signals generated using time-of-arrival (TOA) algorithms. These algorithms rely on direct-path measurements for accuracy. Multipath environments therefore pose a problem when measuring signals from the audio spectrum. The errors induced by a multipath environment can be reduced by introducing additional audio receivers to the detection system. By sampling all possible combinations of a minimum set of receivers (four), a more accurate location can be calculated. An accuracy of six meters can be achieved roughly 69 percent of the time, though most of the error occurs in the vertical component. An accuracy of six meters in the X/Y plane can be achieved approximately 97 percent of the time.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Integrating the B-2 Into Link 16 Operations
Network centric warfare is a key enabler to present day military operations. Link 16, a tactical data link, is one means that combat air forces utilize to leverage network centric warfare. In the past, the B-2 community relied on stove-piped communications systems, but now the B-2 is in the early stages of implementing a fully integrated Link 16 system. This paper will show that the current integration of Link 16 will enhance the B-2's overall mission effectiveness by decreasing aircrew workload, increasing situational awareness, and eliminating many opportunities for human error. However, the current Link 16 implementation also has several hurdles to overcome in order to be fully effective. These hurdles, which include implementing hardware and software improvements, maximizing training opportunities, and emphasizing a commitment to Link 16 use in combat operations, are also addressed.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Counterair
This white paper examines the counterair mission in 2025--what it is, what the threats are, how we counter them. In the broadest sense, the counterair mission will not change in the next thirty years. The basic premise of air superiority--neutralizing or destroying an adversary's ability to control the skies--will remain intact. This paper examines the counterair mission by first performing an analysis of three different trajectories. The first is an evolutionary trajectory based on projections of current and programmed capability. The second and third trajectories represent extremes--"anything but" approaches for conducting the counterair mission. The second trajectory is "anything but" inhabited aircraft and the third is "anything but" aircraft at all--performing the counterair mission solely with surface and space-based systems. The results of this analysis will provide us with a basis of comparison for each. Common themes emerged from all three trajectories. The primary theme is a requirement for near-real-time collection, processing and distribution of information, or in some cases knowledge, to support the commander's assessment and reaction to a given situation. A comprehensive holographic display system is required to present the information to the commander.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Behavior of Three Metallic Alloys Under Combined Axial-Shear Stress at 650 C
Three materials, Inconel 718, Haynes 188, and 316 stainless steel, were tested under an axial-torsional stress state at 650 C. The objective of this study was to quantify the evolution of the material while in the viscoplastic domain. Initial and subsequent yield surfaces were experimentally determined to quantify hardening. Subsequent yield surfaces (yield surfaces taken after a preload) had a well-defined front side, in the prestrain direction, but a poorly defined back side, opposite the prestrain direction. Subsequent yield surfaces exhibited isotropic hardening by expansion of the yield surface, kinematic hardening by translation of the yield surface, and distortional hardening by flattening of the yield surface in the direction opposite to the last prestrain. An existing yield function capable of representing isotropic, kinematic, and distortional hardening was used to fit each yield surface. Four variables are used to describe each surface. These variables evolve as the material state changes and have been regressed to the yield surface data.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Theater Space Warfare
Theater space warfare is emerging from two streams of evolution in military space: the role of space in military operations and the role of the theater in space operations. Indispensable at the strategic level throughout the Cold War, space is now proving indispensable at the operational and tactical level. As the incorporation of space into warfare accelerates over the next decade, the concept of space-enabled warfare puts a premium on access to space and effective integration into joint operations. The role of the theater in space operations is also evolving, from passive consumer to that of an active consumer and producer of space effects. Microsatellites, near-space assets, and adversary satellite jammers all necessitate active theater participation in space operations. Unfortunately, today's joint doctrine has missed this on-going evolution, leaving the US military ill prepared to optimize space across joint operations.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
