| 摘 要： | 以某型涡扇发动机为例,介绍应急航空发动机控制,并根据不同的紧急事件,给出两种应急控制模式:增推力控制和快速反应控制.仿真结果显示:释放限制后,增推力控制可以为发动机额外提供16.6%的推力,但同时涡轮前温度上升10.8%;而在标准循环下,快速反应控制将低压转子上升时间从原来的2s缩短至1.675s,响应速度明显加快,与此同时,压气机稳定裕度下降6.05%,高压涡轮导向叶片热机械寿命下降5.16%.

| Abstract: | Taking a certain turbofan engine as an example,the emergency control of aero-engine was introduced,and two emergency control modes were given:overthrust control and fast response control.The simulation results show that after constraint release,overthrust control can provide an additional 16.6% of the engine's thrust,but at the same time,the temperature of turbine inlet rises by 10.8%;and under fast response control,the rise time of low pressure rotor reduces to 1.675s from 2s,however the stability margin of compressor decreases by 6.05% and the thermo-mechanical fatigue life of the turbine guide vane declines by 5.16%. |
