Production at the Leading Edge of Technology
This book contains all contributions to the congress, in which both detailed scientific investigations and technological innovations in the process chains of machining and forming are discussed as well as comprehensive, far-sighted overall views on the planning and control of production processes. These approaches are supplemented by more interdisciplinary cross-sectional topics such as robotics, control engineering, automation, materials technology, additive manufacturing and human-centered production. It is particularly striking that the main approaches presented aim to improve efficiency in production using data-driven methods such as machine learning and artificial intelligence. However, the use of measurement results to improve simulations is also frequently addressed. The book proceedings show that transformations can only succeed through the realization of both detailed technical improvements in production technologies and optimized production organization.

Multi-Dimensional Classification Algorithm for Automatic Modulation Recognition
This thesis proposes an approach for modulation classification using existing features in a more efficient way. The Multi-Dimensional Classification Algorithm (MDCA) treats features extracted from signals of interest as elements with irrelevant identities, hence eliminating any dependence of the classifier on any particular feature. This design enables the use of any number of features, and the MDCA algorithm provides the capability to classify modulations in higher dimensions. The use of multiple features requires an equal number of data dimensions, and thus classification in as high a dimensional space as possible can improve final classification results. Finally, the MDCA algorithm uses a relatively small number of simple operations, which leads to a fast processing time. Simulation results for the MDCA algorithm demonstrate good potential.

Solutions to Three-Dimensional Thin-Layer Navier-Stokes Equations in Rotating Coordinates for Flow Through Turbomachinery
The viscous, Navier-Stokes solver for turbomachinery applications, MSUTC has been modified to include the rotating frame formulation. The three-dimensional thin-layer Navier-Stokes equations have been cast in a rotating Cartesian frame enabling the freezing of grid motion. This also allows the flow-field associated with an isolated rotor to be viewed as a steady-state problem. Consequently, local time stepping can be used to accelerate convergence. The formulation is validated by running NASA's Rotor 67 as the test case. results are compared between the rotating frame code and the absolute frame code. The use of the rotating frame approach greatly enhances the performance of the code with respect to savings in computing time, without degradation of the solution.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Tightly Integrating Optical and Inertial Sensors for Navigation Using the UKF
The motivation of this research is to address the benefits of tightly integrating optical and inertial sensors where GNSS signals are not available. The research begins with describing the navigation problem. Then, error and measurement models are presented. Given a set of features, a feature detection and projection algorithm is developed which utilizes inertial measurements to predict vectors in the feature space between images. The unscented Kalman filter is applied to the navigation system using the inertial measurements and feature matches to estimate the navigation trajectory. Finally, the image-aided navigation algorithm is tested using a simulation and an experiment. As a result, the optical measurements combined with the inertial sensors result in improved performance for non-GNSS based navigation.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Macroscopic Computational Model of Dielectric Barrier Discharge Plasma Actuators
Recent progress in the generation and sustainment of gas discharges at atmospheric pressure has energized research in the field of plasma-aerodynamics. Plasma actuators are promising devices that achieve flow control with no moving parts, do not alter the airfoil shape and place no parts in the flow. The operation of a plasma actuator is examined using a macroscopic (force and power addition) computational fluid dynamic model of a dielectric barrier discharge, DBD, in Fluent . A parametric approach is adopted to survey the range of requisite magnitudes of momentum and energy delivered to the flow field and to identify the effects of this localized momentum and energy addition on the flow characteristics. Simulations consider the initiation and control of flow over a flat plate in a low velocity fluid. The simulation velocity profiles are compared with the experimental observations of Corke (AIAA 2002-0350) as well as simulations of Font (AIAA 2004-3574), Boeuf and Pitchford (JAP 97 103307 2005), and Roy and Gaitonde (AIAA 2005-4631).This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Microstrip Patch Antenna Receiving Array Operating in the Ku Band
Microstrip patch antennas were first investigated from the idea that it would be highly advantageous to fabricate radiating elements (antennas) on the same dielectric substrate as RF circuitry and transmission lines. Other advantages were soon discovered to be its lightweight, low profile, conformability to shaped surfaces, and low manufacturing costs. Unfortunately, these same patches continually exhibit narrow bandwidths, wide beamwidths, and low antenna gain. This thesis will present the design and experimental results of a microstrip patch antenna receiving array operating in the Ku band. An antenna array will be designed in an attempt to improve its performance over a single patch. Most Ku band information signals are either wide band television images or narrow band data and voice channels. An attempt to improve the gain of the array by introducing parasitic patches on top of the array will also be presented in this thesis.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Vibration Suppression of a Rotationally Periodic Structure Using an Adaptive-PPF Control Law
For a compressor disk, effective vibration suppression requires broadband control, and the elimination of inter-blade coupling forces. Previous researchers achieved this using an active-passive piezoelectric shunt network. Unfortunately, optimal tuning of the shunt requires prior knowledge of the coupling strength, which is not well defined. This thesis uses an adaptive parameter estimator to eliminate the inter-blade coupling forces. In addition, the passive shunt is replaced with an analogous positive position feedback method. The resulting control law was used on a simulated four and eight bladed system.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Airborne Wind Energy
Excitement among researchers about Airborne Wind Energy (AWE) technology matches DoD aims to advance and employ renewable energy. AWE seeks to cost-effectively tap the vast supply of wind energy available at altitudes high above the reach of conventional, ground-based wind turbines (e.g. 500-12,000m). This paper explores viability and implementation of AWE technology for fulfilling USAF energy needs. Characteristics, potential, and developmental status of the AWE resource are presented. A design tool for a rotor-based AWE system is developed, facilitating the analysis of blade performance to simplify design and provide the best efficiencies for a range of conditions. USAF bases are evaluated upon energy needs, design requirements, and other factors to determine which bases could benefit most from AWE. Bases most viable for an AWE project, with 75% potential savings on energy costs/base (up to $40M annually for larger bases), are: Tinker, Vance, Wright-Patt, Arnold, Ellsworth, and Grand Forks. Key results reveal it is possible to achieve notable benefits for the USAF using AWE technology.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 AFIT MEMS Interferometric Gyroscope
With the invention of Micro Electro-Mechanical Systems (MEMS) it has become possible to fabricate micro-inertial sensors. These new sensors have application in creating autonomous guided weapons systems. New technologies like Micro Unmanned Aerial Vehicles (UAVs), which cannot use conventional inertial sensors, rely on technologies like micro-inertial sensors to operate. Also, such sensors have the capability to reduce both power and space consumption on conventional aircraft. This technology is not yet mature, and current micro-inertial sensors do not have the accuracy required for highly precise navigation. To try to increase the accuracy of micro-inertial sensors, researchers are turning toward micro-optical gyroscopes. Creating a working micro-optical gyroscope is a difficult proposition as their small size precludes micro-optical gyroscopes from having large enough path lengths to sense useful rotation rates. Techniques need to be developed to create micro-optical gyroscopes with path lengths long enough to sense navigation grade rotation rates. This research proposes a new type of MEMS optical gyroscope. The device, called the AFIT MiG is an open loop Sagnac interferometer on a MEMS die. Mirrors are placed on the die to spiral light inward from the outside to the center of the die thereby increasing the optical pathlength of the device. When the AFIT MiG was simulated using flight profiles generated in MATLAB, the optical path length of the device was long enough to measure rotation rates, which were greater in strength than the noise inherent in the measurement.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 Combined Effects of Freestream Turbulence, Pressure Gradients, and Surface Roughness on Turbine Aerodynamics
A significant amount of research has been aimed toward turbine blade surface roughness, freestream turbulence, and pressure gradients and their associated efficiency losses. Typically, roughness studies use artificially created surfaces that are easily characterized by statistical parameters such as average centerline roughness, Ra, which is, in turn, often correlated to the well-defined equivalent sandgrain roughness, ks. This research differs in that it uses scaled facsimiles of real turbine blade surfaces to characterize correlations between blade roughness, with the combined effects of freestream turbulence and pressure gradients, and skin friction coefficient (Cf). The models tested yielded Ra values ranging from 0.1 to 1.2 mm and were representative of eroded, fuel deposited, pitted, and thermal barrier coated (TBC) surfaces with spallation. For the eroded surfaces, the addition of roughness caused Cf increases up to 300% when compared to flat plate data. Addition of freestream turbulence caused increases up to 125%. The combined effects of roughness and turbulence yielded increases up to 380%. This is 55% larger than simply summing the two independent effects. Though other surfaces typically offered less dramatic results, it was concluded that the Cf increases due to combined effects were consistently higher than the corresponding sum of the parts. The results presented for the combined effects of roughness and pressure gradients were inconclusive due to errors in measurement. However, limited observations seem to corroborate the trends seen with zero pressure gradient.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Conceptual Design Tool to Analyze Electrochemically-Powered Micro Air Vehicles
A multi-fidelity conceptual design tool was developed to assess electrochemically-powered micro air vehicles(MAVs). The tool utilizes four areas of contributing analyses (CAs): aerodynamics, propulsion, power management, and power sources to determine the endurance duration of a given mission. The low-fidelity aerodynamic CA consisted of drag polar calculations and the high-level CA used a vortex theory code called Athena Vortex Lattice (AVL). The propulsion CA employed QPROP and a MATLAB code that used experimental propeller data and motor constants to predict propeller-motor combination performance for the low- and high-fidelity tracks, respectively. The power management CA determined the percentage of required power the power sources needed to provide by a user-defined split or an optimization to maximize endurance duration for the two fidelity options. The power source CA used specific energy and specific power calculations for the low-fidelity track and polarization curves and Ragone plots for the high-fidelity track.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 Guiding Center Plasma
"The Guiding Center Plasma" presents a detailed exploration of plasma physics, focusing on the guiding center approximation. This approach simplifies the complex dynamics of charged particles in strong magnetic fields, making it essential for understanding phenomena in controlled fusion, space physics, and astrophysics. Harold Grad's work offers a rigorous mathematical treatment suitable for researchers and advanced students in physics and engineering. The book covers fundamental concepts such as particle orbits, adiabatic invariants, and the derivation of fluid equations from kinetic theory. It elucidates how the guiding center approximation enables efficient modeling and simulation of plasma behavior, particularly in scenarios where the magnetic field dominates. This exposition remains valuable for anyone seeking a comprehensive understanding of theoretical plasma physics and its applications.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
