摘要
Abstract
To reduce the badness of the flight environment of the boost phase in the hypersonic flight test, a novel optimization method to generate 3-DOF optimal trajectory was proposed. The method based on the angle of attack ( AOA ) encoding genetic algorithm was adopted, and the cubic spline was employed to smooth attack angle time courses. During the optimization process,the feasible solution was first searched to meet window parameters. Then the optimal trajectory with the lowest badness of flight environment was searched for the objective functions such as attack angle range,the maximum dynamic pressure and the maximum normal overload parameters under the constraint of the windows parameters. The results show that the algorithm can avoid the local high risk in the theoretical trajectory,and it has good robustness.关键词
