Near-optimum guidance schemes for abort landing flight in a windshear
In this thesis, near-optimum guidance schemes for abort landing trajectories in a windshear are investigated. These near-optimum guidance schemes are based on the properties of the optimum trajectories. The survival ...
The effect of lift on aeroassisted orbital transfer trajectories
Miele, Wang, and Deaton have demonstrated in Ref. 1 how optimal trajectories are produced by eliminating positive lift and fixing the lift coefficient at its lower, negative (downward) bound all throughout the atmospheric ...
Comparison of gradient-restoration algorithms for optimal control problems with nondifferential constraints and general boundary conditions
The problem considered here involves a functional I subject to differential constraints, nondifferential constraints, and general boundary conditions. It consists of finding the state x(t), control u(t), and parameter $\pi$ ...
Determination of optimal parameters for aircraft take-off guidance strategies in the presence of windshear
Low-altitude windshear is a threat to the safety of aircraft in take-off and landing: over the past 20 years, some 30 aircraft accidents have been attributed to windshear. The Aero-Astronautics Group of Rice University ...
