Abstract

A projectile comprises a tubular body and a sabot or impact base connected to the rear portion. The tubular body is connected to the sabot by radially extending pins, and the rear face of the body is spaced from a circular shoulder of the sabot by a distance equal to, or larger than, the diameter of the pins. To ensure a transfer of the spin of the sabot to the body, the rear face of the body is provided with a corrugation, such as teeth, or a knurling, which, at the discharge and after the pins are sheared off, digs into the surface of the circular shoulder.

Claims

1. A projectile comprising a tubular projectile body having a rear portion with a bottom face, a sabot having a forward portion connected to said rear portion and having an exterior surface with an annular groove, a rotating band inserted in said annular groove, said rear portion of said projectile body being of a size and shape conformable to the forward portion of said sabot and being engaged one within the other, and a plurality of uniformly circumferentially distributed radial pins connecting said tubular body rear portion to said sabot forward portion, said sabot forward portion being inserted into said rear portion of said projectile body and including a raised exterior wall portion defining a shoulder, said rear portion of said body terminating in said bottom face spaced from said shoulder by a distance at least equal to a diameter of said pins connected between said sabot and said projectile body, said bottom face of said tubular body having corrugations facing said shoulder for forming an engagement with said shoulder of said sabot after said pins are sheared to impart spin of said sabot at least partly to said tubular projectile body, said rear portion having an outer diameter corresponding to an outer diameter of said shoulder, said projectile body being made of material which is harder than that of said sabot and said corrugations being selected to have at least one of a depth and an edge sharpness for permitting at least some slippage between a spin of said sabot and an imparted spin of said tubular body.

2. A projectile according to claim 1, wherein said sabot opens toward said projectile body, the opening comprising a blind bore.
