摘　　要：针对高频阵列多管炮武器齐射对弹丸外弹道特性的影响问题,建立了弹丸齐射的流场特性模型和运动模型,并运用Fluent软件计算得到了不同初速、间距等条件下弹丸的气动系数,将得到的气动系数用于弹丸的外弹道计算,分析了弹丸轨迹的变化。研究表明,弹距过小时运动弹丸产生相互排斥,从而影响弹幕密度,在武器设计中应予以考虑。Aim to the problem that the salvo of multi barrel rotary gun with extra-high firing rate impact on the aerodynamic characteristics of its projectile,the flow field model and the movement model while salvoing were built.According to Fluent software,the aerodynamic coefficients under the condition of different initial speeds and different projectile distances were computed,and these aerodynamic coefficients are used to calculate the exterior ballistic,whose track change was analyzed.Studies have suggested that the projectiles would repulse each other with too short projectile distance,so as to the density of barrage would be effected,which should be taken into account in the weapon design.
