质心位置对超空泡射弹稳定性影响的规律研究

摘要

The influence of center of mass for stability of supercavitation projectile was researched.The mathematical model of projectile stability moving with supercavitation was constructed.And experimental analysis were made based on several projectiles with vary center of mass.The analysis shows that the fronter center of mass is advantageous to stability of projectile with the same shape.%研究了质心位置对超空泡射弹水中运动稳定性的影响规律。建立了射弹运动稳定性数学模型;并对几种不同质心位置的射弹进行了实验分析。研究结果表明,对于相同外形的射弹,射弹质心前移有利于射弹的运动稳定性。
