弹丸贴膛一般运动与减小射弹散布措施的研究

STUDY ON PROJICTILE GENERAL MOTION TOUCHING THE BORE WALL AND THE APPROACHES REDUCING THE PROJECTILES DISPERSION

本文建立了非对称弹丸前定心部紧贴炮膛壁一般运动的横向运动微分方程;求得了对称弹丸在膛内的贴膛运动规律,并与弹带中心沿炮膛轴线运动假设下的弹丸贴膛运动进行了对比。指出了减小射弹散布的措施。

The general differenteal equations of unsymmetrecal progectile lateral motion torching the bore wall with the bourrelet have been developed in this paper. The pattens of symmetrical projectile motion touching the wall with the bourrelet have been studied. They have been compared with projectile motion that it had been assumed that its rotating band center traveled along the axis of the vore and the bourrelet touched the wall. The approaches reduing projectiles dispersion have been made.
