以超空泡射弹火炮武器发射的高速超空泡射弹为研究对象，采用数值模拟和理论分析相结合的方法，研究水下串行超空泡射弹的自然空化流场，分析不同串行发射工况射弹之间的干扰状况，探索串行间距对空泡形态、流场特性、射弹运动规律等问题的影响规律，获得了水下高速超空泡射弹串行运动的理论最优发射间隔距离。
The high-speed and super-air-bubble projectile launched by the supper-bubble projectile is studied in this paper.The natural cavitation flow field of underwater serial supercavitation projectile is studied by numerical simulation and theoretical analysis,and the interference between projectiles in different serial launching conditions is analyzed,the influence of serial distance on the bubble shape,flow field characteristics and projectile motion law are explored.The theoretical optimal launch interval for the serial motion of underwater high-speed supercavitation projectile is obtained.
