摘要

为了得出火药气体压力与时间关系的解析式,在前人得出的内弹道半实验解法的基础上,对火药气体压力与时间的关系近似地计算,以前人计算得出的火药气体压力与时间关系为依据,论证用Vallier公式简化计算火药气体压力的可行性,并用中间值迭代方法对给定一些条件后的火药气体压力曲线进行逼近,得出逼近后的Vallier公式曲线,将各平台火炮内弹道修正系数的平均值作为经验值来计算火药气体压力。结果表明,Vallier公式能够较好地计算出一般火炮的火药气体压力和无后坐火炮的火药气体压力上升段。
        In order to draw the analytic relationship between gunpowder gas pressure and time,based on previous results of the semi-empirical formula of ballistic solution,the relationship between gunpowder gas pressure and time is approximately calculated.The feasibility of simplifying the gunpowder gas pressure calculation by Vallier formula is demonstrated. The powder gas pressure curve is approximated after using the intermediate value iterative method to give out some conditions. The average value of trajectory correction coefficient with each platform artillery is calculated as the experience value of the gunpowder gas pressure. The results show that Vallier formula can be used to calculate the gas pressure of general artillery gunpowder and ascent of recoilless artillery gunpowder gas pressure well.
