涡轮效率改变对发动机加速特性的影响

Effect of turbine efficiency changing on turbo-engine's accelerating characteristic under closed-loop control mode

采用零维闭环数值仿真平台,对某型单轴涡轮喷气发动机进行启动加速过程的零维闭环仿真,通过选择三种不同的调节方式,研究了涡轮效率的改变对发动机的转速、推力和耗油率等发动机特性的影响,其中某些结果与实验数据进行了比较。

Zero-dimensional closed-loop simulation was implemented to one single-shift jet engine through simulation test-bed. The effect of turbine efficiency changing on turbo-engine's characteristic, such as thrust, rotating speed and SFC, was discussed in three different control mode, and some results were compared with test data.
