Based on a turbofan engine flight test, this paper studies the modeling method and thinking of aeroengine simplified model, and verifies the model by flight test. The established engine acceleration real-time model is used to optimize the engine acceleration performance, and the flight test is used to verify the effectiveness of the optimization method. The results show that the accuracy of the engine acceleration model established based on the flight test meets the requirements and can effectively guide the formulation of the optimization measures for the acceleration performance of the engine.
