Optimal reentry and planechange 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 augmentedLagrangian, nonlinearprogramming code known as VF01A. Several minor modifications are necessary because of long computation times and the singularity in the headingangle equation. Nevertheless, rapid convergence is obtained for the maximumcrossrange problem, and the sensitive maximumorbitalplanechange problem is solved successfully by this modified code.
