Hypersonic Vehicle Trajectory Optimization

Abstract

The purpose of this task is to assemble a computer code for solving the maximum crossrange and maximum plane change problems for hypersonic vehicles. These problems are formulated as parameter optimization or nonlinear programming problems by replacing each control function by a number of nodal points and linear interpolation. An existing code for solving the nonlinear programming problem with the augmented-Lagrangian method is used to perform the optimization. Derivatives are calculated numerically by central differences. The code works well in that both trajectory optimization problems are solved successfully. By changing that part of the code which defines the problem, this code can be used to solve any trajectory optimization problem.
