摘要
本文借助P_1^(n-1)=u_1/A·s_1/s_2·v_(m2)/v_m公式,计算并讨论了三种压力指数大于1硝胺发射药的最大稳定燃烧压力P_1以及n、s、v_m对P_1的影响;通过分析30滑膛内P-t曲线、压差曲线和几种火炮弹道试验结果,对硝胺发射药在高压火炮中使用的安全性做出了肯定的结论。
This paper relates to the calculation, using the equation p_1^(n-1),of the maximum stable burning pressure P_1 in a gun for three kinds of Nitramin gun propellants having the pressure exponent of burning rate n higher than 1. The paper also discusses the effects of n(pressure exponent), s (burning surface area) and v_m (projectile velocity at P_1) on P_1. Some useful conclusions on the safety of using Nitramin gun propellants in high pressure guns are obtained by analysing the P-t curves and differential pressure curves in a 30 caliber smooth bore gun and some gun ballistic test results.
