一种异形卷弧翼弹气动特性的数值模拟

Numerical Simulation of Aerodynamic Characteristics of A Missile with Abnormity Wrap Around Fins

采用CFD方法计算了一种异形卷弧翼弹的气动特性,得出了轴向力系数、法向力系数、横向力系数、滚动力矩系数、偏航力矩系数和俯仰力矩系数曲线,所计算的系数可以用于弹的外形结构设计和弹道仿真。

In the paper, aerodynamic characteristics of a missile with abnormity wrap around fins is computed by CFD method, and the curves of axial force coefficient, normal force coefficient, lateral force coefficient, roll moment coefficient, yaw moment coefficient and pitch moment coefficient is plotted. The coefficients can be used in shape design and trajectory simulation.
