摘　　要：文中主要利用商业CFD软件Fluent对某型末制导炮弹的末制导段在不同攻角、不同飞行马赫数的气动特性进行了数值仿真,得出了该型末制导炮弹升力系数、阻力系数和滚转力矩系数随飞行马赫数和攻角的变化规律。结果表明,计算所得气动参数可以为该末制导炮弹编制高精度射表提供数据依据和参考。The commercial CFD software Fluent was used for simalation of aerodynamic charactirestics of some terminal guided munitions in terminal segment under different affack anyle and mach, the variation lay of or lift coeflienct, drag coeflient and roll moment coefficient with flight mach and attacls angle was obtained, The semulation result shows the caculated aerodynarve parameters can be referend to high accuracy firing table for the terminal guided projectile.
