渐速膛线身管内的弹丸贴膛运动

PROJECTILE'S MOTION TOUCHING THE WALL OF INCREASING TWIST RIFLED BORE

建立了非对称弹丸在挠性渐速膛线身管内作贴膛运动的微分方程组,求解了对称弹丸在渐速膛线理想身管内的运动规律,并与等齐膛线身管内的弹丸运动进行了对比。

Differential equations of an unsymmetrical projectile's motion touching the wall of a flexible increasing twist rifled bore with the bourrelet are developed. The patterns of a symmetrical projectile's motion touching the wall of an ideal increasing twist rifled bore with the bourrelet are studied and compared with that of a projectile traveling in a uniform twist rifled bore.
