A shell with a subcaliber penetrator, which has a conical tailpiece, and with a basically disk-shaped propulsion element, wherein the conical tailpiece has a frustum-shaped recess that is open towards the rear end. The propulsion element is joined with the penetrator, preferably by a screw connection (projectile fastening bolt). To this end, a bolt element joins the propulsion element and the penetrator in the area of the tailpiece and has a borehole that is open at the rear end, into which propellant charge gases flow when the shell is fired and cause rending of the bolt element and thus separation of the propulsion element from the penetrator.

Projectile fastening bolt for a shell with a subcaliber penetrator with a conical tailpiece and a shell

A sabot projectile with a subcaliber projectile body and a sabot, which includes a propulsion element that acts on the rear end of the projectile body and a segmented, essentially cylindrical metal guide cage, which is located at the front end of the propulsion element. The guide cage has a central opening that extends in the axial direction, through which the projectile body is passed. So that the sabot projectile is relatively inexpensive to manufacture, has a low weight, and ensures good detachment of the sabot from the projectile body after discharge, the guide cage is a hollow cylinder, on whose inside wall preferably several radial transverse ribs are arranged, which are spaced some distance apart and extend both in the direction of the longitudinal axis of the sabot and in the direction of the projectile body.

Sabot projectile

A sabot projectile with a subcaliber penetrator and a sabot, which has a propulsion element that acts on the rear end of the penetrator, a segmented, essentially cylindrical guide cage, which is connected to the front end of the propulsion element, and a segmented, disk-shaped metal guide element that extends radially inward in the front area of the guide cage and holds the penetrator. The disk-shaped guide element has a slightly convex contour in the direction of flight of the projectile and the material and the wall thickness of the guide element are chosen in such a way that convex area of the guide element is pushed back slightly when the sabot projectile is fired, so that the outer marginal area of the guide element rests against the inside wall of the gun barrel from which the sabot projectile is fired, and/or the inner marginal area of the guide element, which faces the penetrator, rests against the outer surface of the penetrator.
