针对传统航空发动机响应速度慢,难以在紧急事件中用于控制受损飞机完成起降过程的问题,采用高速慢车控制模式来提升发动机加速性能,通过增加发动机在慢车时高压压气机转速,为加速前期提供更大的燃油流量,从而缩短发动机从慢车至最大状态的加速时间。为保证慢车时高压转子转速提高的同时发动机推力和稳定裕度不变,通过修改高压压气机可调导叶控制计划来调整高压转子工作点。仿真结果显示,与原有控制相比,采用高速慢车快速响应控制模式的发动机加速上升时间从原来的2.00s缩短至1.86s,而高压压气机最小喘振裕度仅由16.01%下降至14.81%,同时慢车推力基本保持不变。
In response to the slow response speed of traditional aeroengine, it is difficult to control the damaged aircraft in the emergency to complete the take-off and landing process. The high-speed local vehicle control mode is adopted to improve the acceleration performance of the engine. By increasing the engine high-pressure compressor speed in the idle mode, Early to provide greater fuel flow, thereby shortening the engine from the local car to the maximum acceleration time. In order to ensure that the high-pressure rotor speed is increased while the engine thrust and stability margin are unchanged, the operating point of the high-pressure rotor is adjusted by modifying the adjustable guide vane control plan of the high-pressure compressor. The simulation results show that compared with the original control, the acceleration rise time of the high-speed local train rapid response control mode is shortened from 2.00s to 1.86s, while the minimum surge margin of the high-pressure compressor is reduced from 16.01% to 14.81% , While the slow car thrust remained unchanged.
