国外运载火箭可重复使用关键技术综述

Survey and Review on Key Technologies of Reusable Launch Vehicle Abroad

运载器的可重复使用是未来航天运输系统的主要发展方向,具有重要的应用价值。可重复使用运载火箭能够有效降低发射成本,但也会遇到许多技术难题。针对Falcon 9火箭的研制情况,分析国外多级入轨可重复使用火箭发展历程,分析研究实现可重复使用运载火箭所需要解决的关键技术难题,为新型航天运输系统的发展提供参考。

The reusable launch vehicle is a main development tendency of space transportation system. Although the reusable launch vehicle can reduce the launching cost, it will encounter a great deal of technical problems. In this paper, based on the experiments of Falcon 9, and analyzing the project of the TSTO reusable launch vehicle abroad, the critical technologies will be researched and the results will provide references for the research of new type of space transportation systems.
