摘要
在分析间冷回热涡扇发动机工作机理的基础上,进行了大涵道比间冷回热涡扇发动机循环参数分析。以波音767-200ER量级飞机为装机对象,开展了间冷回热发动机方案研究。对比分析了间冷回热涡扇发动机与多种类型涡扇发动机的总体性能方案,并从发动机总体性能及特性的角度,比较分析了大涵道比涡扇发动机引入间冷回热技术所带来的收益。最后,提出了研制间冷回热涡扇发动机需突破的主要关键技术。
Cycle parameters study and performance calculations of an intercooled recuperated turbofan en-gine with high bypass ratio for aircraft as large as Boeing 767-200 ER were carried out on the basis of inter-cooled recuperated cycle working principle. The advantages of introducing intercooling and recuperation in-to turbofan engine were analyzed by means of comparison of performance and characteristics with otherkinds of turbofan engines. At the end, key technologies for developing intercooled recuperated aero enginewere proposed.
