摘要
针对未来载人登陆火星任务,比较了化学推进、电推进及核推进的优缺点,指出核热推进是未来载人登陆火星的首选。简述了美国和俄罗斯在核热推进的研究进展,指出核热/发电双模式是未来载人登火的发展趋势。提出我国近地轨道5次对接、人货分离载人登陆火星构想。在此基础上,设计了单台推力15 t,比冲940 s载人核热发动机并提出我国核热火箭2016—2035年发展研究规划。
With the high-speed development of space technology in the 21 stcentury,the main space faring counties have proposed manned Mars exploration initiatives in 2030 s. In this article,the advantages and disadvantages of chemical,electrical and nuclear rocket were compared at first. It was found that nuclear thermal rocket( NTR) technology was the best choice for future manned Mars exploration. Then,the development history of nuclear thermal rocket in US and Russia was reviewed,and the nuclear thermal / electrical bimodal technological trend was presented. Finally,Chinese prime human mars exploration architecture,crew / cargo separation and 5-times LEO docking,were proposed. Based on this architecture,a 15 t single-thrust and 940 s impulse nuclear thermal engine was designed and Chinese NTR development-research plan between 2016 and 2035 was presented.
