摘　　要：简要介绍了飞行模拟器中发动机地面启动过程的特点。重点分析了发动机地面启动过程的建模方法,以保证满足飞行模拟器对发动机系统地面启动过程仿真精度的要求。本文以某民航飞机涡轮风扇发动机为例,建立了飞行模拟器的发动机地面启动过程数学模型,并运用MATLAB对其进行仿真建模。研究结果表明运用MATLAB对本文提出的数学模型进行仿真建模,其仿真精度可以达到飞行模拟器对发动机启动过程的精度要求。To begin with, the engine ground start-up characteristics of flight simulator are introduced and the method of ground start-up process modeling is analyzed. Then based on a civil aircraft turbofan engine as an example, this paper establishes a mathematical model for the engine ground start-up process of flight simulator, and applies MATLAB to the simulation modeling. The research results show that using the MATLAB modeling for the proposed mathematical model, the simulation accuracy can be achieved, thus meeting the simulation accuracy requirements of flight simulator.
