Description

The invention relates to an armored projectile with a head placed on the tip, which consists of a layer of soft and a layer of hard material, both in a flat end face end, one layer being formed in a ring shape.

Projectiles of this type are usually provided with a shell made of tempered steel, on the one hand holds the tip support and on the other hand prevents parts of the brittle core from being hit by the Target to be disseminated. At small angles of incidence, a bare carbide body has better gripping ability than a hard metal core provided with a tip support and sleeve, but with larger impact angles the last-mentioned type of bullet is the first-mentioned in terms of penetration capacity think.

The aim of the invention is to provide a projectile with good penetration capacity at large angles of impact and to create with good gripping ability even with very small angles of impact.

The armored projectile according to the invention differs from the known embodiments of this type especially advantageous in that the soft layer consists of solder, which the annular Layer holds in place, this annular layer having an outer diameter which is the largest Corresponds to the diameter of the armored bullet and is made of hard metal in a known manner.

The advantage achieved in this way is that the annular layer at small angles of incidence in penetrates the target surface without damaging the tip of the core. As a result of the friction between the ring-shaped layer and the target surface, the projectile is rotated to a larger angle of impact, so that it can penetrate more easily. During the breakdown of the core, the soft layer acts on known ones Way as a lubricant. The annular layer is used in both large and small The angles of incidence are broken, and consequently the resistance to the barrel of the bullet in the goal is not increased significantly.

The projectile head is advantageously provided with a ballistic hood at its front end.

The armored projectile according to the invention can also be designed as a core projectile for a sub-caliber projectile be. Of course, it can also be used on armor-piercing full-caliber bullets.

According to a special feature of the invention, the armored projectile is wholly or partially in one Steel shell included.

Björn Herman Olof Simmons,

has been named as the inventor

The invention is described below with reference to the drawing which shows an example of one after the Invention constructed armored projectile shows, described in more detail.

In the drawing, 1 denotes a core made of tungsten carbide and 2 a ring made of tungsten carbide, which surrounds the front, pointed part of the core 1. 3 denotes a cast brass filling, which on the one hand soldered the core 1 and the ring 2 together and on the other hand as a tip support for the core 1 serves. 4 denotes a ballistic cap that has no particular influence on the penetration capacity of the projectile, and 5 a fastening device for the tracer set.

When hitting a target surface at large angles of incidence, the ring 2 splinters easily and as a result, it does not form any significant obstacle to penetration of the core 1.

At small angles of incidence, the front edge 6 of the ring 2 tears open the target surface and penetrates it. Here, the ring 2 is easily splintered, but before that a significant torque has been transmitted to the core, which penetrates the target at an angle that is significantly greater than the angle of impact. In addition, the target area is from the ring! has been deformed in a manner favorable for the penetration of the core 1.
The ring 2 can be designed in many different ways. It is expedient that the edge 6 has a large diameter so that the best possible friction moments are achieved on the target surface.

The ring 2 can be provided with predetermined breaking points or non- ring-shaped organs that easily splinter when the core 1 penetrates against it, but which nevertheless have a good ability to transmit frictional forces in the event of oblique impacts, for example a rotationally symmetrical organ made up of sectors.
