180 Trajectory Optimization of Hypersonic Vehicle Using Gauss and Legendre Pseudospectral Method
Download citation file:
This paper presents a trajectory optimization problem of a hypersonic vehicle in 3 degree of freedom under constraints. Here, this problem has been solved using Legendre and Gauss pseudospectral methods. The vehicle trajectory optimized includes ascent, cruise and descend phase. The results have then been compared with results from optimization using single shooting method. The results show applicability of these methods in generating hypersonic vehicle trajectory under constraints for ascent, cruise and descend phase in 3 degree of freedom.
