摘要
基于经典内弹道方程组,引入新的内弹道参数-身管个数,推导了齐射型多管火炮内弹道方程组。结果表明,火药燃气由单个药室沿多个身管膨胀时,引起了内弹道基本方程的显著变化。管数的增加虽然使次要功成倍增加,但弹丸动能也相应提高,二者的比值保持不变,即齐射型多管火炮次要功系数与同口径单管火炮相等。当将齐射型多管火炮内弹道方程组用相对量表示时,它与经典内弹道方程组具有统一的形式。二者之间的区别在于常量的计算方式不同,如药室容积缩颈长l0、弹丸极限速度vj、综合参量B等。通过对常量计算公式的分析,提出了两种齐射型多管火炮内弹道计算的等效方法,即单管等效与多管等效。
Interior ballistic equations set available for multiple-volley gun is developed by introducing the number of barrels as new parameter. The results show that the interior ballistic basic equation is remarkably different from that of classic interior ballistic equations set, because propellant gas has expanded in more barrels. More barrels manyfold increase the secondary work while the projectile kinetic energy increases accordingly,therefore,the coefficient of secondary work of multiple-volley gun,which represented by the ratio of the two,remains the same to that of identical caliber single barrel gun. Interior ballistic equations set for multiple-volley and single barrel gun has uniform shape when expressed by relative quantities. The differences are just in the constant calculation equations,such as the equivalent length of chamber volume l0,maximum velocity of projectile vj,synthesis parameter B,and so on. Based on the comprehensive analysis on these constant calculation equations, two equivalent methods for multiple-volley gun,single barrel equivalent and multiple barrels equivalent,are proposed in this paper.
