Benefits of technology

[0019]One major advantage of the use of deformable plastic material (for example, rubber) for the adjustment elements is that there is no longer any need for mechanical reworking, and the tolerances of the shaping tool can be individually matched to the sabot projectile, and the shaping tool itself need no longer be designed with such high precision.

Problems solved by technology

However, during the production of such discarding-sabot projectiles composed of plastic, it has been found to be problematic to comply with the predetermined tight tolerances for the front guide area of the discarding sabot, by means of which the discarding-sabot projectile is supported on the inside of the corresponding weapon barrel.

Embodiment Construction

[0027]In FIGS. 1 and 4, 1 denotes a discarding-sabot projectile which, for example, is a 120 mm tank projectile that acts as a so-called discarding sabot (alternatively, however, it could also be a discarding sabot). The sabot projectile 1 has a sub-caliber projectile body 2, and an essentially hollow-cylindrical guide sabot 5, which comprises two half-shells (guide sabot segments) 3, 4. A drive disk (pusher plate) 6 is provided in the rear area in the guide sabot 5, and the projectile body 2 is supported on it at the rear.

[0028]The guide sabot 5 is composed, for example, of plastic and, in its front area has a circumferential guide area 7, which projects on the outside, for support on the barrel inner wall of a weapon barrel, which is not illustrated. A (segmented) supporting wall 8 is also provided in the front area of the guide sabot 5, wherein the supporting wall 8 extends radially inward and has a central opening 9 through which the projectile body 2 is passed.

[0029]There is an...

Abstract

To maintain predetermined tolerance conditions for the front guide region (7) of a guide sabot (5) in a simple manner without reconditioning, even if the drive or guide cage (5) is plastic, the invention begins with a premounted cage shot (1), i.e., a sabot projectile, wherein cage segments directly adjacent to one another on circumferential sides surrounding the shot body are selected so that the cage (5) has an outer diameter in the front guide region (7) that is less than the predetermined target diameter (Do). Adjustment of the diameter of the guide region (7) then occurs subsequently, for example, by the insertion of an insert (12.1) designed in the shape of a bushing, wherein the insert has a conical outer surface (13) and is placed into an annular gap (11) remaining between the shot body (2) and segments (19, 20) of a support wall (8) of the cage (5).

Description

[0001]This is a National Phase application in the United States of International Patent Application No. PCT / EP2008 / 005799 filed Jul. 16, 2008, which claims priority on German Patent Application No. DE 10 2007 037 700.4, filed Aug. 9, 2007. The entire disclosures of the above patent applications are hereby incorporated by reference.FIELD OF THE INVENTION[0002]The invention relates to a discarding or guide sabot, and to a method for attachment of such sabots, in particular, for a blank projectile.BACKGROUND OF THE INVENTION[0003]A discarding-sabot projectile is known, for example, from DE 43 30 417 C2. This device comprises a sub-caliber projectile body and a discarding guide sabot, wherein the discarding sabot essentially comprises a drive disk, which is arranged at the rear and on which the rear area of the projectile body is supported, and two discarding sabot segments, which surround the projectile body and are in the form of half-shells. The discarding guide sabot has an external...
