摘要：

基于气体动力学理论，建立了转管机枪膛口助旋制退器的气体动力学数值模型，以此计算了助旋制退器的助旋力和制退力。通过改变助旋制退器沿枪管轴线的纵向尺寸，分析了助旋力和制退力随管道腔长度的变化规律。结合内能源转管机枪发射动力学模型，分别对未安装和安装有不同长度的膛口助旋制退装置的转管机枪系统进行了动力学仿真。仿真结果表明，在一定范围内增大助旋器管道腔沿枪管轴线长度可以有效地增加助旋力和制退力。安装膛口助旋制退器，能够实现对内能源转管机枪射频的有效提升。

Abstract:

A gas dynamic model of muzzle assistant-rotating and recoil absorber for internally powered gatling gun is established based on gas dynamic equations, and the assistant-rotating force and brake force of this device are calculated. The changes of assistant-rotating and brake forces with length are analyzed by changing the lougitudinal size of this device along the axial direction of barrel. The dynamics simulations of gatling guns without and with muzzle assistant-rotating and recoil absorber are performed based on the firing dynamic model of internally powered gatling gun. The results show that the properly expanded length of center chamber and nozzle in the axial direction of barrel can effectively increase the assistant-rotating force and brake force. The brake can be used to significantly increase the firing frequency of gatling gun.

Key words: ordnance science and technology, gatling gun, muzzle assistant-rotating and recoil absorber, firing frequency, dynamic simulation
