基于Fluent的末制导炮弹初始段气动仿真

Fluent-Based Aerodynamic Simulation of Terminal Guided Projectile in Its Initial Stage

利用商业CFD软件Fluent对某型末制导炮弹在不同攻角、不同飞行马赫数的气动力进行计算,得出该型激光末制导炮弹升力系数、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,并对结果进行了分析。

Making use of Fluent CFD software to calculate the aerodynamic force in different angles of attack and different flight mach numbers, we get the laser terminal guided projectile＇s changing rule of lift coefficient, and drag the pitching moment coefficient with the change rule of flight Mach number and angle of attack. Finally, the simulation results are also analyzed.
