为了减小转管机枪射击过程中后坐力引起的架座振动以提升武器的射击密集度,提出了一种利用部分膛内火药气体经过喷管外流反推实现抑制射击振动的稳定方案。结合考虑热散失的内弹道方程以及超音速气体流动方程,建立了转管机枪力偶作用式气体稳定装置的气体动力学模型。对安装有力偶式气体稳定装置的三脚架支承转管机枪系统进行了刚柔耦合发射动力学建模和仿真,研究了该装置对抑制转管机枪连发振动和提升射击精度的实际效果,为转管武器连发振动控制提供了新思路。
Abstract
In order to reduce the tripod vibration caused by gatling gun recoil and improve the fire density, a scheme of powder gas outflow through nozzle to achieve vibration suppression was carried out. The gas dynamic numerical model of gas force stabilization device was built based on gas dynamic equation of supersonic airflow and variable mass thermo dynamics interior ballistic equation, and the changes of stabilization force with installation position and gas port area was analyzed. Combined with the rigid-flexible coupling launch dynamic model of gatling gun system which installed gas force stabilization device, the control effect of gas stabilization force couple on vibration of gatling gun system was calculated. The results provide a new method for vibration control for gatling gun system.
