Space-Based Launch Scheme and Planning Strategy Simulation

为更好地发挥天基系统的能力,研究天基发射方案、相关应用技术以及远程导引路径规划。以空间平台发射追踪器与目标交会问题为例,基于飞行任务提出了三种冲量推进的发射方案及规划算法。重点分析了基于发射窗口的发射方案和基于非线性规划的发射方案,结合所设计的规划流程和规划算法,建立相应的数学模型并进行仿真。仿真结果表明,对于发射窗口的遍历计算方案能够为决策优化提供足够多的发射时机和姿态选择;非线性规划的数值寻优方案可以为规划策略提供多种约束下的最优选择方案。研究结果为天基发射任务和组合机动路径规划提供了有价值的参考。

To play better ability of space-based system,the space-based launch technology was investigated,including launch strategy,application technique and long-range guidance trajectory planning algorithm.Taking spacebased launch rendezvous for example,three kinds of launch strategies and planning algorithms were proposed according to flight mission differences.Two methods were discussed.With launch strategy analysis,planning process and planning algorithm were designed.Then,some mathematical models were established.Simulation results show that ergodic calculation graphic method based on lunching window can be draw up to reveal to decision makers a wide choice of lunching opportunities and attitude angles.Numerical optimization method with nonlinear programming can obtain the optimal scheme for combined impulsive orbit maneuver.Some results are valuable for applications on space operations.
