发动机火焰筒的热疲劳损伤是导致火焰筒失效的主要原因，本文提出了一种火焰筒热疲劳损伤假设，认为火焰筒热疲劳损伤不是由于发动机的运行和停车时冷热温度循环造成的，而是发动机启动时瞬态温度传导过程中材料循环塑性变形的结果，利用该假设结合有限元计算模拟了火焰筒产生疲劳损伤的原因。 - A mathematical model is developed for simulating transient performance of the turbofan engine , in which the transient heat transfer between the components and airflow , tip clearance and components efficiency changes caused by heat transfer are analyzed
