Wing-stabilized training projectile

The invention relates to a wing-stabilized training projectile for target shooting, consisting of an im essentially cylindrical projectile body, arranged at the tapered rear end of a wing control unit and the one front, perpendicular to the projectile body axis has running end face, on which in the projectile axis a fuse in a combat ammunition for the shaped charge development necessary spacing receiving pin is arranged in the area of the front end has a radial collar.

Such training projectiles essentially correspond in shape, dimensions and weight to the corresponding combat ammunition. she serve as blind exercise ammunition that neither powder nor Contains primers for training, i.e. for practicing loading and unloading and setting. Instead of the explosive charge an inert mass of the same density can be pressed in or poured in or a cavity can be left, if it is also guaranteed that the training floor

exactly the same dimensions, the same weight that has the same center of gravity and the same ballistics as the combat ammunition. In such a case, the Target shooting also uses the same target board. Instead of the igniter, there is a detonator adapter.

The practice floor of the type mentioned at the beginning serves to

wing-stabilized shaped charge shell, as it is in "3heinmetall, weapon technology manual" published December 1972, page 466 and page 467 described is. The shape chosen for this known shaped charge projectile results from the fact that the wing control unit is practically the same caliber and with a relatively short projectile of this type only sufficient Stabilization of the projectile can be achieved if a special shape on the Gfeochoss head Circular flow is created, which causes a pressure equalization, whereby the destacbilisierer.de Luftkraft— f πoment is reduced at the projectile head. |

The object of the present invention is to provide a training floor

According to the invention, this object is achieved by the features of the claims.

RHEINMETALL

By dividing the projectile into an essentially cylindrical projectile body, one that supports the wing control tapered rear end and a pin attached to the end face of the projectile body, it is possible for this three parts to choose such a training using appropriate materials that exactly the same weight, the same center of gravity and the same »dimensions can be achieved as with the combat floor and thus also the same ballistic properties. In addition, the most suitable processing method for each projectile part can be selected and partially standardized semi-finished parts can be used that only have a minor Need post-processing.

Further details and advantages of the invention emerge from the following, using one shown in the drawing Embodiment given description, wherein in the drawing the exercise body according to the invention partially is shown in longitudinal section.

As can be seen, the training projectile according to the invention consists of a substantially cylindrical projectile body 2 which is hollow and which is screwed with its rear end onto a tapered rear end 4 of the projectile. The projectile body 2 consists, for example, of steel and is manufactured using the extrusion process. At the extreme rear end of the projectile a Flügel1eitwerk 6 is arranged, which is virtually the same diameter as the projectile body through slipping guide ring 8 is H at the connecting joint between the projectile body 2 and the tapered rear end arranged, since the projectile is intended to be from a Weapon to be fired with the barrel drawn, without. However, the projectile itself should receive a twist.

In the front end face 10 of the projectile body 2 is a Bore 24 arranged. This hole 24 is used for receiving a provided on the pin 12 cylindrical extension 16 which is inserted into the bore 24 with a close fit. the The pin 12 is braced against the end face 10 by means of a nut 20 which is attached to a thread 18 of the cylindrical extension 16 is screwed, between the nut 20 and the inside of the end face 10 a washer 22 is placed. In order to secure the nut 20 against loosening, it can be secured with the threaded pin 18 caulked or riveted.

The connection between the pin 12 and the projectile— body 2 can also be press fit in the bore 24 which, if necessary, is also secured by caulking or riveting.

In the case of combat ammunition, a cap is arranged at the front end of the pin 12, which cap covers the fuse located below. For aerodynamic reasons, this cap has a radially protruding collar. The exercise is accordingly shot such a covenant in the form of a spring ring 14, which is in an un running groove 15 is inserted at the front end of the pin 12 is shown.
