次口径脱壳飞行体气动特性的数值模拟研究

Numerical Simulation on the Aerodynamics of Sub-Caliber Shelling Flying Object

设计了某次口径脱壳飞行体的三维模型,根据流体力学知识,对弹丸和卡瓣的气动布局分别进行了仿真模拟,得到了两者的主要空气动力参数,以及不同马赫数下弹丸和卡瓣的气动特性与周围流场的变化情况。

The three-dimensional model of sub-shelling flying object was established. According to the knowledge of fluid mechanics, the simulation of the pneumatic layout of the projectile and the card flaps was simulated by using the fluid mechanics simulation software. Then the main aerodynamic parameters of the two were obtained, and the aerodynamic characteristics of the projectile and the card flaps were changed in different Mach numbers.
