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%.
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%.
