摘要
以气体动力学理论为基础,通过求解后效期导气孔处的压力和内能、在导气孔处气体的流动的4种状态(正流临界、正流非临界、反流非临界及反流临界)得出自动武器气室压力的方程组;通过计算机编程编写出求解该方程组的程序,并以某自动步枪为例验证出该方法可行。
On the basis of gas dynamics theory, the equations about automatic firearm＇s air compartment pressure are obtained by solving the pressure and internal energy on the gas port in the after-effect period and the four status of the gas on gas port. These four statuses include critical of drag flow, noncritical of drag flow, noncritical of backward and critical of backward flow. The solution of the equations has been programmed, and then the credibility of the method is proved by a certain automatic rifle.
