摘要
为研究正常式布局巡飞弹的空气动力特性,利用Pro/E建立巡飞弹的三维模型,导入Gambit进行网格划分,采用Fluent软件数值模拟巡飞弹的气动特性并提取弹道气动数据。数值模拟对比研究了不同音速下弹体的绕流流场,获得了压力分布情况。系统地分析了巡飞弹在不同攻角、不同马赫数下升力、升力系数、阻力、阻力系数以及翻转力矩等气动特性的变化规律,研究结果对巡飞弹的气动力设计具有一定的参考价值。
In order to investigate the aerodynamic characteristics of normal configuration loitering munition, the three-dimensional model was established based on Pro/E, which was imported into Gambit to divide mesh, by using Fluent software, the aerodynamics characteristic was numerical calculated and the trajectory data was extracted. The flow field around projectile was studied under different Ma by numerical simulation, and the pressure distribution was obtained. The change rule of aeralynamic characteristics of lift, lift coefficient, resistance, resistance coefficient and overturn moment under different angle of attack and different Mach numbers were systematically analyzed. The re- suits provided reference for the aerodynamic design of loitering munition.
