国外TBCC发动机发展研究

涡轮基组合循环(TBCC)发动机是未来高超声速飞行器最适合的动力系统之一,配备该类发动机的高超声速飞行器具备水平起降、机动飞行和重复使用能力。本文对国外开展的TBCC研究项目(如美国的RTA、FaCET和Trijet,日本的HYPR和ATREX,以及欧洲的LAPCAT)进行了系统阐述,较为详细地分析了各研究项目中TBCC方案特点,表明随着涡轮发动机技术的全面发展,及采用火箭引射冲压和预冷等技术,涡轮发动机的工作马赫数可扩大到4.0,且TBCC发动机具有工程可实现性,是未来最具发展潜力的空天动力。

TBCC Technology Research Abroad

As one of the most suitable engines for high speed vehicle in future,TBCC(turbine-based combined cycle) engine enable aircraft with functions of horizontal take-off,flight maneuver and repeated use.This paper illuminates the various TBCC projects,such as RTA,FaCET and Trijet in U.S,HYPR and ATREX in Japan and LAPCAT in Europe.Through the detailed analysis on the characteristics of various TBCC schemes,it is concluded that with turbine engine trchnology evolution,as well as the application of rocket ram injection and precooling technologies,the working Mach number could be expanded to 4.0,TBCC is feasible in engineering and it is the most promising aerospace propulsion in future.
