摘要:
A sabot for a subcaliber projectile, preferably an arrow projectile, having an essentially cylindrical guide gage (8) of a lightweight material and a tail-side drive element (14) detachably connected thereto for tail-side support of the projectile body (1). The guide cage (8) has a radially inwardly-extending support wall (12) for supporting a projectile body (1) disposed therein in its forward to central region, and the drive element is a propelling disk (14) that is received by a circumferential or annular groove (13) in the tail region of the guide cage (8), which is segmented in the axial direction of the projectile body (1). As a result, a further reduction in weight can be accomplished with simpler fragmenting of the sabot that practically does not impair the projectile at all.

The present invention relates to a method of disassembling large-caliber combat cartridges, particularly armor-piercing cartridges, including a combustible casing jacket that conically widens in the direction of the projectile, a casing bottom and a casing cover to which is fastened a sub-caliber projectile equipped with a propelling sabot.To be able, on the one hand, to reduce expenditures for the disassembly of such combat cartridges and, on the other hand, to reuse a major portion of the original combat cartridges for the production of corresponding training cartridges, it is proposed to separate the casing jacket as well as the casing cover starting at their outer circumference, in regions having approximately the same, predetermined diameter D1. This diameter D1 here corresponds to the maximum diameter of the component of the new cartridge to be produced later from the disassembled components. The portion of the casing jacket and of the casing cover disposed between the regions is discarded and is replaced in the production of the new cartridge by a cylindrical casing jacket component having the diameter D1.

The invention relates to a projectile including a cylindrical receiving chamber (4) delimited by an interior wall (3) for a braking parachute (17) which can be ejected by way of a piston (9) that is longitudinally displaceable in the projectile, with the piston (9) being chargeable by an ignitable pyrotechnic charge (10). The braking parachute (17) is encased in a longitudinally divided sleeve (18) one side of which is in engagement with the piston (9). In order to completely or partially recover the projectile and not to impede deployment of the braking parachute (17), it is provided that the rear of the receiving chamber (4) is sealed by a cover (23) which can be ejected by way of the piston (9), is equipped with a rotational imbalance (26) and is in engagement with the other side of the sleeve (18). The braking parachute (17) is fastened to the piston (9). The projectile or a part (1) thereof connected with projectile components to be recovered is provided with a catch ring (21) disposed at the rear exit end of the receiving chamber (4) for the piston (9). The sleeve (18) is able to pass through the catch ring. Guides (19, 28) for the sleeve (18) are provided at the interior wall (3) of the receiving chamber (4).

A method of providing a high-explosive projectile with desired areas of fragmentation includes the following steps: securing a steel plate component in a circumferentially extending recess in the outer surface of a projectile body; directing an energy beam to outer surface portions of the steel plate component; heating, by the energy beam, narrow zones to a temperature above the melting temperature of the steel plate component to a predetermined depth thereof; and cooling the heated zones for effecting structural metallurgical changes in the steel plate component for obtaining the desired areas of fragmentation.

The technical area of the present invention relates to an anti-tank weapon comprising a finned projectile of the arrow type and a launching shoe.The projectile of the invention comprises a shoe 2 the rear portion of which has fins 10 provided with pins 11 which rest against the compression cone 7 of the tube of the weapon. These fins make it possible to obtain practically constant compressive pressure and assure a proper guidance of the projectile during the barrel phase.Application to the field of armaments.

摘要:
A vane assembly for a projectile has a carrier carrying a plurality of pivots, having at the pivots respective carrier elements, and adapted to be secured to an end of the projectile. Respective vane elements are each pivotal on the pivots between an inner position lying immediately adjacent the respective carrier element and within a projection of the projectile and an outer deployed position projecting beyond the projection. Respective heat-destructible pins engaged between the vane elements and the respective carrier elements normally retain the vanes in the inner position and release the vanes for movement into the outer position when destroyed by heat. The carrier element is a rib of the carrier against which the respective vane lies when not deployed. In addition, relative to a normal longitudinal direction of travel of the projectile carrying the assembly, the vanes extend longitudinally in the direction and have relative to the direction front leading ends engaging the respective pins and rear trailing ends at the respective pivots.
