内爆炸的小口径杀伤爆破弹毁伤效率评价模型及优化设计

A MODEL FOR THE ESTIMATION OF THE EFFECTIVENESS OF SMALL BORE SHELLS MEANT FOR INTERNAL BLAST: THE OPTIMUM DESIGN OF SHELL PARAMETERS

本文以小口径杀伤爆破弹直接命中飞机并在内部爆炸的条件,研究了毁伤效率的评价模型和弹药参数的最优选择问题。选择易损面积作为毁伤效率的评价指标,建立了计算易损面积的数学模型。并以37mm杀伤爆破弹对某型飞机射击的实例进行优化设计计算,结果表明该弹的最佳装药量为120g左右,与国外最新装备的相近口径的杀伤爆破弹的装药量相近,说明本文建立的模型是可行的。

The paper discusses a model for estimating the effectiveness of anti-aircraft small bore shells meant for internal blast and deals with the optimum selection of shell parameters. The vulnerable area is used in the case of internal blast as the measure of effectiveness. A model for estimating the vulnerable area is established, using the case of 37mm fragmentation-blast shell shoots at a models of aircraft as a concrete example for the calculation. The results show that the optimum explosive charge for the 37mm fragmentation-blast shell is about 120 gram, a value rather close to those used on shells of similar calibre abroad. This model can be used to conduct scheme demonstration and preliminary design as well as evalution of small bore fragmentation-blast shells.
