备注

结合航班化航天运输系统的概念特征及后续发展思路,首先研究了航班化航天运输系统动力技术的特征需求,并从1 h全球抵达和天地往返运输系统建设以及空间转移运输系统建设两个方面提出对动力技术的总体发展需求,最后从明确发展路线、转变设计理念、加强基础研究和发展新型动力这4个方面,提出我国发展航班化航天运输系统的动力技术挑战。

Considering the conceptual characteristics and the development road-map of space transportation system in airline-flight-mode, the characteristic demand of the propulsion system for airline-flight-mode aerospace transportation are proposed firstly. Then,the overall development demand of propulsion technology are put forward from two aspects: the development of 1 h global arrival and space shuttle and the development of space transfer transportation system. Finally, the technical challenges of propulsion technology for aerospace transportation system in airline-flight-mode are summarized as four aspects, which include determining the development road-map, changing the design methodology, strengthening the fundamental research and developing the innovative propulsion technologies.
