摘要
为优化运载火箭弹道,以微小型固体运载火箭为研究对象,通过Simulink建立六自由度仿真模型,开展弹道优化相关问题的研究与分析。结果表明,在运载火箭发动机推力给定的条件下,此运载火箭达到入轨条件的最大有效载荷为218.8 kg,比基本方案提高9.4%。
In order to optimize the launch vehicle trajectory,This paper takes the micro-small solid-state launch vehicle as the research object,and establishes a six-degree-of-freedom simulation model through Simulink,and carries out a research and analysis on the issues related to ballistic optimization.The analysis results show that under the condition given by the thrust of the launch vehicle engine,the maximum payload of the launch vehicle reaching the orbital condition is 218.8 kg,which is 9.4%higher than the basic scheme.
