Optimization of flight trajectories in a three-dimensional model of windshear flow field
This thesis is concerned with the optimal flight trajectories in the presence of a three-dimensional windshear. Both the take-off and abort landing problems are studied. A mathematical model of a three-dimensional windshear ...
Optimal combat maneuvers of a next-generation jet fighter aircraft
This thesis deals with the optimization of four classes of combat maneuvers for a next-generation jet fighter aircraft: climb maneuvers, fly-to-point maneuvers, pop-up attack maneuvers, and dive recovery maneuvers. For the ...
Ascent performance feasibility for next-generation spacecraft
This thesis deals with the optimization of the ascent trajectories for single-stage suborbital (SSSO), single-stage-to-orbit (SSTO), and two-stage-to-orbit (TSTO) rocket-powered spacecraft. The maximum payload weight problem ...
Optimal trajectories for hypervelocity flight
This thesis discusses optimal trajectories for hypervelocity flight of interest in aeroassisted orbital transfer. Both coplanar orbital transfer and noncoplanar orbital transfer are studied. For these cases, the GEO-to-LEO ...
Windshear identification and detection in simulated and real environments
This thesis considers windshear identification and detection problems by utilizing random process and statistical analysis techniques. A 3D windshear/turbulence model is developed, which covers a broad spectrum of windshear ...
Windshear estimation along the trajectory of an aircraft
The application of the sequential gradient-restoration algorithm (SGRA) to the estimation of the windshear along the trajectory of an aircraft is studied. Based on the measured trajectory data obtained from the digital ...
