Optimal reentry and plane-change trajectories
Abstract
Two optimal trajectories for a hypersonic vehicle, maximum crossrange and maximum orbital plane change, are computed in order to demonstrate the utility of approximating functional optimization problems by using an augmented-Lagrangian, nonlinear-programming code known as VF01A. Several minor modifications are necessary because of long computation times and the singularity in the heading-angle equation. Nevertheless, rapid convergence is obtained for the maximum-crossrange problem, and the sensitive maximum-orbital-plane-change problem is solved successfully by this modified code.
