发射药在不同装填条件下燃气生成规律的分析

Analysis on Gas Generation Rule of Gun-Propellant Under Different Charging Conditions

为了研究发射药燃气的实际释放规律,以发射药的燃气生成猛度作为基本参量,对发射药燃气生成猛度在不同条件下的变化规律进行理论分析,并结合密闭爆发器和内弹道数据,绘制和分析不同情况下的Г–ψ曲线,得到在不同装填密度、不同类型的火药和定容、变容条件下,发射药实际燃烧的变化规律。

In order to study the actual release rule of gun-propellant gas, using the gas generation brisance as basic parameter, the change rules on the gas generation brisance of gun-propellant under different conditions were theoretically analyzed, and the F-~ curves under different situations are drawn and analyzed by combining the closed bomb and interior trajectory data. The change rules on actual combustion of gun-propellant under different charging densities, different types of gun-propellants and constant volume, varied volume conditions were obtained.
