Change regularity of rotation speed of impulse correction projectile

To research the change regularity of projectile rotation speed in trajectory correction process, the influence factors of rotation speed were studied based on angular motion equations of impulse correction projectile. The balanced rotation speed was deduced after impulse correction. According to the characteristic of correction trajectory, the change regularity of rotation speed of projectile after impulse action was obtained. The study result indicates that the radial eccentricity caused by the impulse action is the main factor which causes the large change of rotation speed. The change degree of rotation speed is concerned with the magnitude of impulse, the radial eccentric distance and the number of working impulse motor, and the process that the speed goes equilibrium is independent of the impulse.
