摘要
借助于商业CFD软件FLUENT,对某型空空导弹在不同攻角、不同飞行马赫数的气动力进行了计算,得出了该型导弹升力系数、阻力系数和俯仰力矩系数随飞行马赫数和攻角的变化规律以及导弹表面的压力分布、温度分布和来流速度分布。结果表明,计算的气动参数可以为导弹的外形设计提供依据和参考,与传统计算方法相比有一定的优越性。
In virtue of Fluent of CFD software, we carry though computation of aerodynamics of an air-to-air missile in different Mach meter and different attack angle and gained movement trend of lift coefficient.drag coefficient and pitching moment coefficient with variety of Mach number and attack angle, meanwhile, we also obtain distributing trend of pressure.temperature and weather velocity. The results indicate the computation result could offer basis and reference for shape design of missle. It has more advantage than traditionary computation methods.
