通过对未来载人火星探测飞行任务的分析,结合未来可能的载人火星飞行方案,对载人火星飞行任务的轨道方案进行了研究,重点对地球到火星飞行和火星到地球飞行的霍曼轨道飞行方案进行了设计,对轨道设计的两个重要参数——飞行所需的速度增量和飞行时间进行了详细计算;同时对飞行的进入、降落火星,及离开火星、返回再入、降落地球等各飞行阶段所需的速度增量进行了计算;根据可能的载人火星探测飞行时间,给出了2042年到2054年的计算结果。此外,还对大椭圆、抛物线和金星借力等轨道设计方案进行了分析,并与霍曼轨道设计方案进行了对比,并得出建议载人火星飞行采用霍曼轨道的结论。
Based on the analysis of the mission of the future manned Mars exploration mission and the future possible manned Mars flight program, the orbital scenario of the manned Mars mission was studied, focusing on the orbit of the Earth from Mars to Mars and into the Earth The flight plan was designed to calculate in detail the two important orbital parameters of the orbit design - the speed increments and flight times required for the flight; meanwhile, flight entry, landing on Mars, and departure from Mars, return to re-entry, landing on Earth The calculation of the incremental speed required for each phase of the flight is based on the probable flight time of the manned Mars and the results from 2042 to 2054 are given. In addition, the orbital design such as large ellipse, parabola and Venus was analyzed and compared with the design of the Holman orbit. Finally, the conclusion was proposed that the orbit of the manned orbit Mars was used.
