DE10115088A1 - Projectile used as tank ammunition comprises tail unit with folding wings rotatably connected to holding element for holding tail unit in folded position - Google Patents

Abstract

A projectile comprises a tail unit (7) with folding wings (8); and a sleeve- or ring -like holding element (9) for holding the tail unit in the folded position. The wings are rotatably connected to the holding element. Preferred Features: The inner surface of the holding element has a progression for fixing the wings and the holding element. The holding element has longitudinal grooves distributed over its inner surface and extending parallel to the longitudinal axis of the projectile. The sleeve is made from an inert or combustible material.

Description

The invention relates to a missile with a tail unit, with a retractable guide factory wings and a sleeve or holding them in the folded position annular holding element.

Missiles with retractable tail fins are for example from DE 30 48 941 C2 known. To lock the tail wings in place and this only at or after the launch to swing out into the exposed position admit, a retaining ring is pushed onto the rear end of the tail unit Firing burns.

A disadvantage of the known missiles has been that the retaining ring is not is rotatably mounted on the tail wings so that, for. B. when transporting the ent speaking ammunition by slightly turning the projectile the tail wings and / or parts of the retaining ring can possibly be damaged.

The invention has for its object a missile of the type mentioned Specify the type of wear loads due to a relative movement between the tail wings and the holding element can be avoided.

This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention are disclosed in the Unteran claims.  

The invention is essentially based on the idea that the tail wings are rotatably connected to the holding element. The non-rotatable is preferably carried out Connection by appropriate shaping of the inner surface of the holder Elementes seen in the circumferential direction.

In a first embodiment of the invention, the holding element has its in nere surface distributed, extending parallel to the missile longitudinal axis de longitudinal grooves, in which the sides facing away from the missile are folded Intervene in the tail wing.

In a further advantageous embodiment of the invention, the inner upper Surface of the holding element on the contour of a polygon, such that the tail surface gel are each arranged in a corner of the polygon.

The holding element, which can also be a holding strap, can be made from egg an inert material (cardboard, fabric, plastic) or a combustible material (e.g. a sleeve made of nitrocellulose and cellulose). The distance voltage of the holding element after firing the shot can therefore, depending on the material selected, by ejection from the launch tube together with the missile or by Ver burn preferably take place within the launch tube.

In the case of large-caliber ammunition (e.g. tank ammunition), the fixation of the hold can element from the outside by gluing to the sleeve cover, which corresponds to this The projectile is connected to the cartridge case.

Further details and advantages of the invention follow from the following hand of figures illustrated embodiments. Show it:

Figure 1 is a partially sectioned side view of a rear located in egg ner cartridge case projectile according to the invention.

Fig. 2 shows a cross section through the projectile shown in Fig. 1 along the section line indicated there with II-II and

Fig. 3 corresponding to Fig. 2 cross section of another projectile according to the invention.

In Fig. 1, 1 denotes a cartridge which can be fired from a tank cannon, of which only the area on the projectile side is shown. The sub-caliber Ge lap is marked with 2 and the flanking, which is indicated by dashed lines, the combustible cartridge case with 3.

The projectile 2 comprises a penetrator 4 and a positive cage 5 arranged on the latter. The penetrator 4 and thus the floor 2 is attached via a sleeve sendeckel 6 in a known manner to the cartridge case 3 via a Klebeverbin extension.

On the rear part of the penetrator 4 , an empennage 7 is arranged, the leading wings 8 of which can be folded and are in the folded position. By means of a sleeve-shaped holding element 9 made of a combustible material, the guide vanes are held in this position. The holding element 9 is glued to the outside of the sleeve cover 6 .

As can be seen in FIG. 2, the holding element 9 has distributed over its inner surface 10 , extending parallel to the longitudinal axis 11 of the longitudinal grooves 12 , in which the side facing away from the floor 2 of the retracted tail wings 8 engage.

When the cartridge 1 is fired, the holding element 9 also burns in the (not shown) weapon barrel with the sleeve cover 6 , so that the tail wings 8 are pressed after the weapon barrel has been released either by the incoming air and / or by a pre-tensioned spring into its unfolded position become.

The invention is of course not based on the embodiment described above  limited. So the non-rotatable connection of the tail wings and the holding element in the folded state of the tail wing the inner surface of the holding element, for example, have the contour of a polygon, the Tail wings are each arranged in a corner of the polygon.

A corresponding exemplary embodiment is shown in FIG. 3. 6 with around the sleeve cover and 4 with the penetrator with the tail fin 8 which is sensitive in the folded state. The holding element identified by 13 has the shape of a quadrilateral, the empennage wings 8 being arranged in the four corners 14 . On the outside, the holding element 13 is glued in the corner areas to the sleeve cover 6 .
