固体运载火箭发射轨道一种快速生成方法

A Rapid Generation Method of Solid Launch Vehicle Launch Orbit

通过采用牛顿迭代法快速优化发射方位角,克服了发射方位角初值偏差过大的缺陷,极大缩短了优化时间。通过采用基于特征参数网格化的程序角优化设计技术,建立了程序角设计参数数据库,在机动发射的情况下能够快速进行参数插值,避免了大量优化计算过程,有力地支持了机动发射情况下发射轨道的快速生成。最后通过仿真证明设计算法的有效性和正确性。

This article uses the Newton iteration method to quickly optimize the launch azimuth angle,overcoming the defect of excessive initial deviation of the launch azimuth angle,and greatly shortening the optimization time.By adopting feature parameter grid-based program angle optimization design technology,a program angle design parameter database has been established,which can quickly perform parameter interpolation in the case of maneuvering launch,avoiding a large amount of optimization calculation process,and effectively supporting the rapid generation of launch orbit in the case of maneuvering launch.Finally,the effectiveness and correctness of the designed algorithm are demonstrated through simulation.
