摘要
以空间应急响应任务为背景,采用轨道/弹道一体化规划设计方法,实现空间快速响应航天器全程飞行轨迹规划。在分析弹道设计参数对轨道参数影响性的基础上,将弹道规划分为程序角参数设计和发射诸元参数设计,采用改进的粒子群算法和牛顿迭代法进行混合优化求解。算例表明,使用混合优化求解方法收敛速度快,迭代次数少,易于工程实现,能满足一体化任务规划的快速性要求,可为空间快速响应航天器设计提供理论参考。
Taking the operationally responsive space （ORS） task as the background, all-phase trace programming of the ORS spacecraft using orbit-trajectory integrated programming method was accomplished. Firstly, the influence of the designed trajectory features on the orbit elements was analyzed. Secondly, trajectory programming was divided into flight program design and firing data design,which were separately resolved by the improved particle swarm optimization and the Newton iterative method. The result shows that it is effective to program the flight trace by the algorithm proposed in the paper due to the fast convergence rate and the reduced iterative steps. The proposed algorithm can be easily implemented in engineering application. The obtained conclusions can provide theoretical guidance for ORS orbit-trajectory design.
