为了实现准确控制阻尼片面积达到准确控制弹道修正弹的阻力系数的目的,文中设计了一种新型可控的增加阻力式弹道修正机构。在用ADAMS软件验证机构的可实用性后,用Fluent对该榴弹进行了气动特性仿真。并利用质点弹道方程程序估计了其修正量₃。仿真结果表明这种阻力修正机构可以准确控制阻力系数,增阻效果明显,修正量满足需要。

In order to achieve the purpose of accurately controlling the damping plate area to achieve the accurate control of the resistance coefficient of the trajectory correction, a new mechanism which controls correct trajectory by increasing resistance was designed. After availability verification by ADAMS software, Fluent software was used to simulate aerodynamic characteristics of the grenade equipped with this machine. And the particle trajectory equation program was used to estimate its correction. The simulation results showed that the resistance correction mechanism could accurately control the drag coefficient, and the effect of increasing resistance was obvious and the correction met the needs.
