摘　　要：飞机的空气动力学模型是飞行模拟器仿真软件中非常重要的组成部分,它直接反映了被仿真飞机的气动特性。由于该模型中包含众多的气动数据和复杂的数据处理过程,所以高效的实现此模型的功能是开发高逼真度飞行模拟器项目的关键。考虑到基于面向对象C++语言的特点和MATLAB快速实现实时仿真应用的优势,我们实现了空气动力学模型的编制并将其成功应用于自行开发的基于PC的飞行模拟器中。此方法增加了程序的结构性和可移植性,使其便于维护并可以适用于不同的机型,同时也为下一步制定模拟机软件框架积累了经验。Aerodynamic model of the simulated aircraft is an important part in a flight simulator, for it reflects the aerodynamic character directly. It contains numerous aerodynamic data and complex logical operations which need to be handled. Because of the unique features of object-oriented design principles and the advantages of MATLAB in rapid real-time simulation, an aerodynamic model written in C＋＋ was realized and it was successfully applied through S-function in a PC-based flight simulator. This not only made the program structural, transplantable and convenient to maintain for different aircraft types, but also added experiences for the design of flight simulation’s software framework in future.
