中文摘要：
设计了在近地轨道组装具有分组单元结构的载人深空飞船,包括核热推进单元、燃料储箱与供给单元、主动防辐射单元、人工重力单元、深空居住舱与多任务乘员舱等,给出了各个单元的尺寸与质量参数,并对主要单元的具体组成、功能和技术特点进行了分析。在此基础上,本文以编号4660的Nereus小行星为探测目标,设计了两脉冲转移初始轨道,并进行了轨道优化,得到了发射窗口和最优转移轨道。仿真结果表明,给出的最优两脉冲转移轨道单次施加脉冲在5km/s以内,单程转移时间在160d以内,能够满足未来能量较小的载人小行星探测任务。
英文摘要：
The manned spacecraft for deep space exploration,including nuclear thermal propulsion module,fuel tank and supply module,active radiation-resistant module,artificial gravity module,habitation module and multitask crew cabin is designed in this paper.The size and mass of these elements are presented and the composition,function and characteristics of the main elements are analyzed.The two-impulse transfer trajectories are designed preliminarily on the basis of previous analysis,taking No.4660 asteroid named Nereus as the exploration target.The launch window and optimal transfer trajectory are obtained.The simulation results show that the optimal twoimpulse transfer trajectory makes the single impulse within 5km/s and single transfer time within 160 days,which satisfies the low-energy manned asteroid exploration missions in the future.
