ABSTRACT:
Sabot projectiles, especially arrow or fin-stabilized projectiles, should possess as small as possible spin so that they do not begin to oscillate or wobble (nutation) in the air. On the other hand, for the detachment of the sabot from the projectile body at the muzzle of the weapon barrel, it is advantageous if the sabot possesses a spin. According to the invention this objective is attained in that the projectile body or projectile is threaded into the sabot and can rotate relative to such sabot. The threads for threadably connecting the projectile body or projectile with the sabot have a thread course or direction which corresponds to the rifling twist of the weapon barrel. Furthermore, the magnitude of the thread pitch angle .alpha. essentially corresponds to the sliding friction angle .mu. between the projectile body or projectile and the sabot.
