带吹孔的反作用式炮口制退器气体后效作用冲量的解析计算方法

AN ANALYTIC CALCULATING METHOD OF ULTERIOR ACTION IMPULSE OF GAS IN A PASSIVE MUZZLE BRAKE WITH BLOW HOLES

本文在斯鲁霍斯基反作用式炮口制退器气体后效作用冲量计算方法的基础上,通过引进侧孔面积均匀连续变化的假设和建立压力降落函数的方法,首先导出了侧孔倾角相等的反作用式炮口制退器气体后效作用冲量的解析表达式;进而又导出了带吹孔的反作用式炮口制退器气体后效作用冲量的解析表达式。

Based on B. E. method for calculating the ulterior action impulse of gas in a passive muzzle brake, this paper, by introducing the concept of uniformly and continuously varying of the side-hole areas as well as establishing the method of a pressure declining function expression, firstly sets an analytic expression for calculating the ulterior action impulse of gas in a passive muzzle brake with an equal angle of side holes, then, an analytic expression for calculating the ulterior action impulse of gas in a passive muzzle brake with blow holes.
