摘要: 建立带矢量喷管的涡扇发动机动态数学模型。研究了矢量喷管偏转角和偏转角速度对涡扇发动机工作的影响。研究结果表明 ,不同的矢量喷管偏转角速度对发动机涡轮前燃气温度会产生不同温度峰值 ,而且温度峰值随矢量偏转角速度增大而增大。而在一定的不同矢量角作用下 ,发动机的阶跃响应过程调节参数无明显变化Abstract: The mathematical model of turbofan engine transient process with thrust vectoring nozzle was established.The effects of thrust vectoring angle and angular velocity of vectoring on turbofan engine operation were investigated.The results show that the gas temperature at turbine inlet has different peak value at different thrust vectoring angle.The peak value increases with the increase of thrust vectoring angle. No significant change of the engine response to fuel step was found.
