摘要 航空抛放弹内弹道计算通常使用的是形状函数法,具有严格的推导过程,但是当发射药分裂后,二项式函数不能完全体现发射药的形状特征。针对该问题,根据火药几何燃烧定律,通过计算七孔发射药瞬时燃烧面积,提出了等弧厚七孔发射药的内弹道新算法,可以满足当发射药完全燃烧时,相对燃烧面积是零,提高内弹道计算精度。 The shape function method is usually used in interior ballistic calculation of aviation cartridge. It has a strict derivation process, but when gun propellant splits, the binomial function cannot fully reflect the shape characteristics of gun propellant. According to the geometric combustion law of gunpowder, a new calculation method of interior ballistic for equal web size seven-perforation gun propellant is proposed by calculating seven-perforation gun propellant instantaneous combustion area, which can meet that when the gunpowder completely burned, the relative burning area is zero, and it can improve the accuracy of interior ballistic calculation.
