摘要：

Based on the component maps based gas turbine engine simulation model, the engine steady-state performance calculation model is established. Based on the model, the non-augmented supersonic cruise performance of the fourth-generation engine is studied. The effect of different rotational speed of the high-pressure rotor design values and different throttle ratios on engine velocity characteristics is analyzed. The effect of adjusting the throat area of the tail nozzle on the engine velocity characteristics is analyzed. Finally, the non-augmented supersonic cruise performance of the fourth-generation engine has been optimized.
