美国高超声速涡轮基组合循环发动机的进展及分析

Progress and Analysis of U.S. Supersonic Turbine Based Combined Cycle Engine

旨在为未来空天动力技术研究和产品研制提供参考与借鉴。综述了美国高超声速涡轮基组合循环(TBCC)发动机的进展,重点对与涡轮发动机有关的预研计划进行详细描述,如国家空天飞机(NASP)计划、高速推进评估(Hi SPA)计划、猎鹰组合循环发动机试验(Fa CET)计划等。总结与归纳了TBCC发动机的研究发展的特点:TBCC发动机一直是高超声速飞行器研究的关键技术;目前涡轮发动机的首选是现有涡轮发动机改进,未来可能选择正在预研的高速涡轮发动机或自适应发动机;冲压发动机和模态转换技术已经取得明显进展,但还需长期深入验证。

Aim to provide references for future aerospace power technology investigation and product development, the progress of Trbine Based Combined Cycle engine （TBCC） and advanced programs on turbine engine for TBCC were overviewed and analyzed. These programs include the National Aerospace Plane （NASP）, High-Speed Propulsion Assessment （HiSPA）, Falcon Combined Cycle Engine Technology（FaCET）, etc. The analysis results show that TBCC is always key technology for supersonic flight vehicle, the in-service turbine engine is preferred for TBCC at present, high speed turbine engine and adaptive cycle engine will be selected for TBCC in future, ramjet for TBCC and mode transition between turbine engine and ramjet need to be researched deeply.
