Abstract
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.
Claims14
A shell comprising:
- a subcaliber penetrator, which has a conical tailpiece;
- a propulsion element, wherein the conical tailpiece has a frustum-shaped recess that is open towards a rear end;
- and a projectile fastening bolt, the fastening bolt comprising a bolt element that axially connects the penetrator to the propulsion element and has a borehole that is open at a rear end, into which borehole propellant charge gases flow when the shell is fired so that internal pressure that develops in the borehole due to the propellant charge gases leads to a rending of the bolt element and thus to separation of the propulsion element from the penetrator, wherein the bolt element comprises a first subelement for connection with a borehole in the propulsion element, contains the borehole that is open at the rear end, has an internal thread at a front end, and screws together axially with an external thread of a second subelement wherein only an axial end face and an outer peripheral surface of the tailpiece contact the propulsion element, and wherein the tailpiece contacts the propulsion element without play.
A shell comprising:
- a subcaliber penetrator, which has a conical tailpiece;
- a propulsion element, wherein the conical tailpiece has a rearwardly open frustum-shaped recess, wherein all inner surfaces of the conical tailpiece have no surface contact with the propulsion element;
- and a projectile fastening bolt comprising a bolt element that has a borehole that axially connects the penetrator to the propulsion element and is open at a rear end, into which borehole propellant charge gases flow when the shell is fired so that internal pressure that develops in the borehole due to the propellant charge gases leads to a rending of the bolt element and thus to separation of the propulsion element from the penetrator, wherein the bolt element is passed through the frustum-shaped recess and joins the propulsion element and a rear wall of the penetrator, which rear wall borders a front end of the tailpiece.
