在飞行模拟训练器的研制中 ,发动机的起动过程是需要重点研究和模拟的过程之一。本文根据发动机起动工作过程的具体特点 ,采用三段积分法建立了仿真模型并进行了仿真研究。所得结论基本达到了训练器的要求。 In the development of flight simulation trainers, the starting process of the engine is one of the processes that needs to be studied and simulated intensively. In this paper, according to the specific characteristics of the starting process of the engine, a three-stage integral method was used to establish a simulation model and carry out a simulation study. The conclusions reached the trainer basically meet the requirements.
