DE3345618A1 - Carrier projectile - Google Patents

Abstract

In a carrier projectile, secondary projectiles 10 are accommodated in the projectile casing 2. To achieve a simple construction of the carrier projectile, the projectile casing 2 together with the projectile tip 3 is formed by a one-piece injection-moulded plastic part 1, on which predetermined breaking points 5, 6 are formed. Attached onto this plastic part 1 is the rear part 8 which serves as a sabot and which is made thicker than the plastic part 1. <IMAGE>

Description

Girder floor

The invention relates to a carrier projectile for shooting secondary projectiles, which are housed in a projectile jacket, which on the one hand by a projectile tip and on the other hand, closed off by a rear section designed as a propulsion level is.

Such a carrier floor is described in DE-PS 26 09 391. In the case of such carrier projectiles, the projectile jacket opens after it has been fired, see above that the secondary floors emerge.

In the carrier projectile according to DE-PS 26 09 391, the projectile jacket is formed in one piece with the tail section, the tail section must be stable as a sabot be trained. The M el e Dies consists of the same stable material is complex. The bullet jacket with the rear part from a cheap, unstable one Producing material is prohibited in DE-PS 26 09 391. Because then it would be the sabot weak.

The bullet tip is in DE-PS 26 09 391 as a separate part attached to the bullet jacket by means of shear bolts. These break when fired, like this that the bullet tip after leaving the barrel of the bullet jacket in particular therefore triggers because the secondary projectiles are triggered by an additional traction sheave be driven out of the coat.

The object of the invention is to provide a carrier floor of the type mentioned at the beginning To propose a type whose structure is simplified compared to the prior art.

According to the invention, the above object is achieved in that the projectile casing formed with the projectile tip from a one-piece, injection-molded plastic part is, are formed at the predetermined breaking points, and that the rear part on this plastic part is put on.

This carrier floor is simple in construction. Because it consists of only two parts, namely the plastic part and the rear part. It's easy too assemble. The secondary floors are filled into the plastic part. Thereafter the rear part is glued or welded to the plastic part.

Since the propellant gas is applied to the rear section when the carrier projectile is fired acts, it must be designed accordingly strong. The plastic part is preferably weaker than the tail section.

In order to avoid that the rear part of the plastic part when firing expands, the rear part preferably has an edge with which it faces the Includes edge of the plastic part.

The rear section can be made from a fiber-reinforced plastic or from Be made of metal.

Further advantageous refinements of the invention emerge from the following description of an embodiment. The figure shows a carrier ge shot in the cut.

The carrier floor has a plastic part 1.

This forms the projectile jacket 2 and the projectile tip 3. In the area of the projectile jacket 2 are molded onto the plastic part 1 guide rings 4. as Predetermined breaking points are a notch 5 and longitudinal notches 6 on the bullet tip 3 formed on the plastic part 1.

The plastic part 1 is made of polysulfone or polyamide, for example injection molded.

Compared to the bullet tip 3, the plastic part 1 is open The edge 7 of the plastic part 1 surrounding the open end tapers to a point. On the edge 7 a cup-shaped rear part 8 is placed. Whose Edge 9 is running corresponding to the edge 7 to a point and embraces this. The height of the rear part 8 is small compared to the height of the plastic part 1.

The rear part 8 is made of metal, for example aluminum. The rear part 8 can also be made of a fiber-reinforced plastic. For plastic reinforcement carbon fibers or boron fibers can be used.

The edges 7 and 9 are glued or welded together The carrier floor is filled with secondary floors 10. In the tip of the bullet 3 is a damping insert 11 is provided. This absorbs the when the Carrier projectile to the weapon barrel occurring forces, which the secondary projectiles 10 exercise on the plastic part 1.

The secondary projectiles 10 are steel or heavy metal balls. she have different diameters. The spaces between the balls can be foamed. For example, low polyurethane foam is suitable for this Volume weight.

The plastic part 1 and the rear part 8 are easy to manufacture Parts. The assembly of the carrier floor is easy. After inserting the cushioning insert 11 is the plastic part 1 with the Secondary floors 10 filled e If necessary, the spaces between them are filled with foam. Then the The rear part 8 is glued or welded onto the plastic part 1.

The carrier projectile described can fire from drawn tubes will. After passing through the pipe, air resistance and swirl forces cause it Dismantling the plastic part 1 at the predetermined breaking points 5, 6. The secondary projectiles 10 then exit.
