Dynamic analysis on gas operated device´s of internally-powered Gatling weapon

Gas operated device structural parameter is an important factor to affect the firing rate fluctuation of the internally-powered Gatling weapon. In order to improve the movement stability of the automatic machine, Through analyzing internally-powered Gatling weapon´s gas chamber structure, using gas dynamics theory, gas operated device´s math model was erected. In the course of analyzing, it considered an structure effect of gas chamber´s piston driving slide. This paper analyzed an effect of gas operated device´s gas chamber pressure and core´s and piston´s rate to firing rate. This method is applicable to research the gas operated device´s structural parameter design.
