Abstract
An artillery projectile to be fired from a large-caliber gun barrel. The projectile comprises a body whose rear part is fitted with deployable stabilizing fins, wherein the body is sub-calibered and carries at least one ejectable guiding sabot fitted with a sliding drive band to reduce the spin rate of the projectile.
Claims9
A projectile to be fired from a gun, comprising:
- a sub-calibred body with front and rear parts;
- fins fitted to the rear part for deployment to stabilize the body;
- a rear ejectable guiding sabot on the rear part;
- a sliding drive band on the rear sabot, said band for reducing spin rate of the body;
- and
- a front ejectable guiding sabot comprising at least two segments connected to the front part by a temporary connecting means, the connecting means having at least one pin shearable upon firing whereby recoil of the front sabot with respect to the body causes shearing of the pin.
A projectile according to 1, wherein said front sabot possesses an inner profile which matches an external profile of said front part of said body and wherein there is an axial clearance between the inner profile of said sabot and the external profile of the front of said body to allow the relative recoil of said sabot with respect to said body during its longitudinal acceleration in a gun barrel.

- fins fitted to the rear part, for deployment to stabilize the body;
- a rear ejectable guiding sabot on the rear part;
- a sliding drive band on the rear sabot, said band for reducing spin rate of the body;
- a front ejectable guiding sabot comprising at least two segments connected to the front part by a temporary connecting means, the connecting means having at least one pin shearable upon firing whereby recoil of the front sabot with respect to the body causes shearing of the pin;
- and
- deployable pivoting ailerons in the front part.
