转管机枪枪口助旋制退装置,是有效提高转管机枪射速(或减小驱动电机功率)和降低武器后坐力的技术途径。提出了一种新型助旋制退器,建立了助旋制退器的三维模型,对结构进行了分析。建立了助旋制退器流场计算模型与控制方程组,使用Matlab软件对内弹道以及后效期进行计算,利用icem-cfd软件进行网格的划分,用Fluent软件完成流场的仿真,并对助旋力矩进行了计算。结果表明,该枪口助旋制退装置可以为武器提供旋转力矩和制退力。%Muzzle torque assist & brake for gatling machine gun is an effective technical way to improve the gatling gun firing rate (reduce the driving motor power). This paper presents a new type of rotary muzzle brake assist, establishes three-dimensional model of rotary muzzle brake assist, analysis the structural. Establishes auxiliary rotary muzzle brake flow field calculation model and the control equations, on the interior ballistic and aftereffect period were calculated using Matlab software, divides the grid using icem-cfd software, completes the flow field simulation with Fluent software and calculates help rotary torque. The results show that the gun muzzle device can provide help rotary torque and recoil force as a weapon.
