摘要
针对水下枪械的枪口速度与后效期的最大速度有较大的差异,常用的内弹道计算已不适用,建立了水下枪械内弹道模型,分析了水下枪械内弹道符合计算的难点,提出了在水下内弹道计算中采用相关分析法确定符合计算参数。计算实例表明,该方法可缩小协调参数的范围,提高模型的计算精度,为水下枪械内弹道计算建立了新的方法。
In view of the difference between the gunpoint speed of a underwater gun and the maximal speed of the after-effect period, the classical interior ballistics arithmetic is not available. The interior ballistics model is established for underwater gun. The problems are analyzed in interior ballistics calculation. An innovative method is put forward that the correlation analysis is used in interior ballistics calculation for underwater gun. The calaulation example indicates that the range of the coincident parameters is reduced and the calculation precision of the model is improved. It brings forward a new method for the gun interior ballistics calculation.
