【摘要】 通过引入间冷回热涡扇发动机各部件损的计算方法,进一步发展了间冷回热涡扇发动机计算模型和相应的仿真程序。对常规涡扇发动机和间冷回热涡扇发动机各部件的损进行了计算和对比,初步分析了间冷回热涡扇发动机的。结果表明,虽然间冷回热过程带来了新的损失,但显著减小了涡扇发动机高压涡轮和内涵排气流的炳损,提高了发动机的效率。更多还原

【Abstract】 By introducing the exergy destruction calculation method of the engine components,the intercooled recuperated turbofan engine calculation model and the simulation program were further developed.The component exergy destruction was calculated for the conventional turbofan engine and the intercooled recuperated turbofan engine,and comparison between each other was conducted.Preliminary exergy analysis of intercooled recuperated turbofan engine was carried out.The results indicate that,although intercooling and recuperation cause new loss,it can significantly reduce the losses of the high pressure turbine and the engine core exhaust stream,and improve the engine exergy efficiency.更多还原
