Abstract

Aiming at the problem that the tail wing is damaged in the process of opening due to the high muzzle rotationalspeed of the guided projectile, the force and rotational speed law of the guided projectile in the process of moving in-bore are studied. The zero dimensional interior ballistic mathematical simulation model and the force model of the motion in-bore are established. The factors influencing the muzzle rotationalspeed of the guided projectile are analyzed, which provides a reference for the design and improvement of the muzzle rotationalspeed of the guided projectile basis. Taking a guided projectile as an example, the mathematical simulation of the proposed method to improve the rotationalspeed of guidance projectile is carried out, and the correctness of the simulation model is verified by flight test.

Key words： guidance projectile; interior ballistics; in-bore rotational speed; muzzle rotational speed
