Abstract

In order to minimum the time-to-climb of hypersonic vehicle, the trajectory of hypersonic vehicle boost segment is studied. The optimal control model of boost trajectory is analyzed, and Gauss pseudospectral Method (GPM) is applied to discretize the optimal problem into nonlinear programming problem (NLP). Finally, Matlab software package SNOPT is used to solve the NLP problem. Numerical simulations show that the trajectory derived by this method is not sensitive to initial conditions and fairly good in real-time property.
