摘要 以大涵道比涡扇发动机为研究对象,分析了风扇增压级、高压压气机、高压涡轮、低压涡轮和燃烧室部件效率对涡扇发动机共同工作的影响。不同部件效率变化,不同的控制规律列部件的共同工作影响不同,有些参数变化方向相反。 A high bypass ratio turbofan engine is used as an example, to analyze the influence of major component efficiency changes, including fan, booster, compressor, high pressure turbine, low pressure turbine and combus- tot, on engine overall performance. It shows that under different control laws, the effects of different component ef- ficiency on engine performance could be different, and even at opposite directions.
