Abstract:By using the Gaussian pseudo spectral method, the optimization of the farthest lateral glide trajectory of spacebased reentry vehicles is studied, and aerodynamic modeling methods are proposed for axisymmetric aircraft dynamics models. A Gaussian pseudo spectral method is used to establish a nonlinear optimization problem, and an analytical Jacobian matrix solution method is given. Under various path constraints, the trajectory optimization simulation is performed using the lateral glide distance as the performance index. Simulation results show that this method can effectively solve the optimization of the farthest lateral glide trajectory of spacebased reentry vehicles.
