关于RBCC动力系统的思考

回顾了RBCC动力系统研发的历程和趋势,分析了RBCC动力系统的速度、高度等基本特性。建议RBCC动力系统研发应致力于火箭发动机与冲压发动机功能的拓展与完善,注重综合性能的提高;加强与飞行器一体化设计,考虑进气道、燃烧室、尾喷管及燃油供应系统的共用;依据具体飞行器方案开展关键技术攻关和基础技术研究;首先开展临近空间高速、机动飞行器动力系统研发,针对两级入轨动力系统之二级开展关键技术攻关。

Thinking about RBCC propulsion system

The development course and trend for the rocket based combined cycle （RBCC） propulsion system are reviewed. The velocity, altitude and other basic characteristics of the RBCC propulsion system are analyzed. A suggestion that the development of the RBCC propulsion system should be devoted to improving the function and performance of LRE and ramjet is proposed. It is found that the integrated design of the RBCC propulsion system and aircraft should be enhanced; the sharing of air intake duct, combustor, tailpipe nozzle and fuel supply system might be considered in the integrated design; the study of key and basic technologies of RBCC propulsion system must be carried out according to the specific aircraft project. The development of high-speed aircraft propul- sion system running in the near-earth space should be conducted first to tackle the key technology for the second stage of two-stage-to-orbit propulsion systems.
