摘　　要：气动系数模块是飞行性能仿真中的主要组成部分,主要完成飞行性能仿真中气动力和力矩的计算,气动系数数值的准确与否对飞行性能仿真的逼真度起关键性作用。由于计算机的发展,计算流体力学CFD(Computational Fluid Dynamics)的地位与作用很快得到提高。以纵向气动系数为例,探索利用计算流体力学CFD软件FLUENT对飞机进行实体建模,从而弥补气动数据的不准确或不完备问题,建立完备而准确的气动数据库,实时在线解算气动系数,进一步真实模拟飞机的飞行性能。Aerodynamic coefficient module is a major part in the simulation of the flight performance,it mainly completes the air force and torque calculations in flight performance simulation, so it plays a key role in the fidelity of flight simulation. Due to the development of the computer, the status and role of computational fluid dynamics CFD （Computational Fluid Dynamics）improves quickly. This paper takes longitudinal aerodynamic coefficients for example, to explore the use of computational fluid dynamics CFD software FLUENT in solid modeling of aircraft, which makes up the inaccurate or incomplete data, so establishes a complete and accurate aerodynamic database, calculates the coefficients online, and it further improves the simulation of aircraft flight performance.
