摘要

中冷回热航空发动机是在常规发动机循环基础上加入了中冷和回热两个环节

有效利用了发动机排放的热量

提高了热效率

降低了耗油率

是新概念节能环保发动机.利用MATLAB平台

建立了基于部件特性的三轴分排涡扇中冷回热发动机总体性能仿真模型.利用该模型对分排涡扇中冷回热发动机进行性能仿真计算和热力循环分析.计算结果表明:在相同的循环参数和单位推力水平下中冷回热航空涡扇发动机比常规循环涡扇发动机具有更低的耗油率.

Abstract

Intercooled recuperated aero-engine(IRA) is built based on conventional engine while intercooled and recuperated cycles are incorporated.It can utilize effectively engine's heat

improve the thermal efficiency and reduce the specific fuel consumption.The intercooled recuperated aero engine presents a new concept about "green" engine.On the MATLAB platform

an overall performance simulation model has been developed on the intercooled recuperated tri-spool turbofan engine with split exhaust.Then

performance simulation and thermal cycle analysis was carried out under this model.The result indicates that

with the same thermal cycle parameters and specific thrust

the specific fuel consumption of the IRA is less than that of the conventional turbofan engine.
