摘要
针对载人火星探测任务,结合我国现有技术基础,提出我国载人火星探测方案,重点研究载人火星探测任务推进系统的设计。首先,综合考虑载人深空探测任务的约束,采用Pork-Chop图设计了适用于不同任务场景的转移轨迹;然后,参考我国空间站技术,基于核热推进系统设计了我国载人火星探测任务的飞船;最后,对核热推进系统的发动机台数和推力进行了优化,得到了适用于不同任务场景的最优推进系统组合方案。本文所研究内容为我国未来载人火星探测任务提供了有益参考。
A manned Mars exploration concept based on the nuclear thermal propulsion is proposed for China's future Mars exploration. Firstly,the transfer trajectories suitable for different types of missions are designed using Pork-Chop.Secondly,according to the mission requirements,the spacecraft is designed by referring to the space station technical standards. Thirdly,the number and thrust of the nuclear thermal engines in the propulsion system are optimized to ensure that they can complete the mission with low costs and high reliability. The optimal solutions of the propulsion system are obtained for long-term and short-term Mars missions. Finally,the processes of the different manned Mars exploration missions are described in detail. The content of this article provides a useful reference for China's future manned Mars exploration missions.
