基于相对压力冲量的火药能量释放规律

The Energy Release Law of Propellant Based on Relative Pressure Impulse

为了研究火药实际能量的释放规律,通过对几何燃烧模型的分析和修正,建立了相对压力冲量形式的修正模型,并在不同装填密度、不同类型的火药和定容、变容条件下进行了理论和实验分析。结果表明,修正模型更好地体现了火药实际能量的释放规律,说明修正模型所建立的理论及处理方案是合理的。

The correctional model of relative pressure impulse format is established by analysing and correcting the geometric combustion law for studying propellant actual energy release law. Theoretical and experimental analysis under the conditions of various loading density, propellant, constant volume and variational volume are made. The results show that the actual energy release law is embodied in correctional model. The theory and scheme established by correctional model is reasonable.
