炸弹从飞机上投下后,由于受初始条件的作用,其弹轴将围绕质心而摆动。炸弹的摆动运动必将对质心运动产生影响。本文将这种影响归结为相当的初速减小量。在电子计算机上计算了诸方面的弹道,求得了初速减小量的估算公式,建立了初速减小量与炸弹投放条件之间的近似关系。这个关系式对求算投放初始条件的修正是有帮助的。 After the bomb dropped from the plane, its projectile will swing around the center of mass due to the initial conditions. The bounce movement of the bombs will have an impact on the movement of the center of mass. This article attributes this effect to a corresponding reduction in muzzle velocity. The trajectories of various aspects were calculated on the computer. The formula for estimating the muzzle velocity was obtained. The approximate relationship between muzzle velocity and the conditions of the bombs was established. This relationship is helpful for calculating fixes for initial delivery.
