摘要
建立了序贯装药金属风暴武器的轴对称二维两相流内弹道计算模型,数值模拟了不同发射情形下该武器的各发弹的内弹道过程。计算结果表明:采用12.7 mm的序贯装药金属风暴武器发射弹丸时,膛内的二维效应不明显;对于同一装填位置的弹丸,发射频率越高,最大膛压越高,弹丸初速越小。
The axial-symmetrical two-dimensional interior-ballistics model of metal storm weapon system with powder loaded in serial mode was established. The interior-ballistics process under various firing modes was simulated numerically. The simulated results show that the in-bore two-dimensional effect is not evident with 12.7 mm diameter metal storm weapon system. For a fixed cartridge, the higher the firing rate is, the higher the maximal pressure is and the smaller the muzzle velocity is.
