摘要

摘要: 针对大气辅助捕获下多次穿越的方式,分别建立探测器气动捕获段在静止大气和旋转大气模型下的轨道动力学方程并进行相应的动力学仿真,分析旋转大气对轨道捕获的影响.根据仿真结果,给出了在两种大气模型下完成目标捕获时,任务耗时以及探测器所受的热量、过载情况,通过给定不同目标轨道近火点高度,得出两种大气模型下卫星轨道的轨道参数变化形式.结论表明:当目标轨道近火点高度较低时,旋转大气对探测器轨道参数的变化形式影响较大,应该考虑旋转大气的影响.

Abstract: With regard to the human exploration of Mars, based on aerobraking, the dynamics equations for the Mars vehicle were established, both in the static and rotating atmospheric environment. Simulations of the flight databases were generated by a Matlab process based on a three-dimensional dynamic model.A comparative performance analysis of atmospheric models was carried out using details of the duration, aerodynamicloading of the Mars vehicle, and other orbital parameters. The results show that changes of the orbital parameters form are large difference under the rotating and static atmospheric environments on the low periareon, the influence of the rotating atmospheric environment should be considered.
