Application of the Level Set Method to Solid Rocket Motor Simulation
(2012-04-19)
The body of work encompassed in this thesis merges two advanced concepts for developing
flow solutions with level sets to develop an accurate and e cient method for simulating solid rocket motor grain regression. The ...
Development and Implementation of a Trajectory Prediction Methodology
(2012-04-16)
Operation of unmanned aircraft in the United States' National Airspace System (NAS) is currently severely restricted, primarily due to the need to ensure adequate separation between manned and unmanned aircraft (UA). A ...
Shape Memory Alloy Robotic Truss
(2008-09-09)
The development, design, and analysis of a Shape Memory Alloy Robotic Truss (SMART) actuator is presented in this research paper. SMART is a three-degree of freedom actuator capable of large rotary and bending displacements ...
Effect of Coordinate Switching on Simulation Accuracy of Translunar Trajectories
(2008-09-09)
This thesis focuses on the effect of round-off error in the accurate simulation of translunar trajectories. The three-body dynamics can be posed in either an Earth-centered (EC) or Moon-centered (MC) frame. In this study, ...
Methods for Optimization of a Launch Vehicle for Pressure Fluctuation Levels and Axial Force
(2008-09-09)
A computational fluid dynamics (CFD) code has been combined with a Genetic Algorithm (GA) to perform a shape optimization study on a two dimensional axisymmetric model of a typical launch vehicle. The objective of this ...
Launch Vehicle Performance Enhancement Using Aerodynamic Assist
(2008-09-09)
A complete preliminary design model of a three-stage solid-fuel launch vehicle
has been combined with a genetic algorithm to perform an optimization study with the
goal to enhance performance using aerodynamic assist. ...
Aerodynamic Testing of a Circular Planform Concept Aircraft
(2008-09-09)
Auburn University has entered into collaboration with Geobat Flying Saucer Aviation Inc. for aerodynamic and flow visualization studies of the Geobat aircraft. The aircraft model that was tested consisted of a circular ...
Yaw-Roll Coupled Oscillations of a Slender Delta Wing
(2008-09-09)
The delta wing has been a highly studied aerial planform, from counter rotating vortices to a rolling `wing rock' motion. The research done at Auburn University is an extension of those studies. This research studies not ...
Development of a 3-D Fluid Velocimetry Technique based on Light Field Imaging
(2011-05-04)
A novel method for performing 3-D particle image velocimetry is developed and demonstrated. The technique is based on light field photography, which uses a dense lenslet array mounted near a camera sensor to simultaneously ...
Characterization of Numerical Error in the Simulation of Translunar Trajectories Using the Method of Nearby Problems
(2011-05-04)
This thesis focuses on analyzing the effect numerical error has on the accurate simulation of translunar trajectories. The method of nearby problems is employed to estimate the numerical error. A simulation is developed ...
