为研究旋转稳定弹道修正弹修正能力,在理论上对舵进行了受力分析,并深入研究了舵结构参数、初速、海拔、射角对修正弹修正能力的影响。研究结果表明:弹丸纵向远修修正能力小于纵向近修的修正能力,横向左修修正能力小于横向右修修正能力;弹丸的绝对修正能力随着初速的增大而增大;海拔越高弹丸在射程与偏航上的修正能力越小;修正弹在纵向射程上的绝对修正能力随射角的改变不大,而偏航方向上变化较为明显。

In order to study 2-D spin-stabilized projectile trajectory correction ability, this paper analized the rudder force in theory, and in-depth study of the different rudder structural parameters, initial muzzle velocity, elevation, launching artillery projectile impact angle of correction ability. The results show that the long-range correction ability of the projectile is smaller than that of the longitudinal repair, and the lateral left repair ability is smaller than the horizontal right correction ability; the absolute correction ability of the projectile increases with the increase of the initial velocity; as the altitude increases, both the absolute correction ability and relative correction ability of the projectile in range and yaw decrease; The absolute correction ability in the longitudinal range varies little with the change of the angle of the arc, and the absolute correction ability in the lateral yaw changes more obviously with the change of the angle of the arc.
