Description

The subject of the main patent is an incendiary projectile, in particular an armored incendiary projectile, which has an approximately cylindrical projectile body tapering at the front, filled with incendiary material, in which the head of the projectile body, which is made of hardenable steel, is provided with a predetermined breaking point and is hardened in such a way that after penetrating a Armor splinters and flies to the target together with the flammable mass of fire caused by friction, impact and shock when exposed to atmospheric oxygen. The object of the invention of the main patent was to create a projectile through which the incendiary material arranged behind the penetration core is carried fully into the target located behind the armor plate. For this purpose, the projectile was designed in such a way that the incendiary material intended for action behind the armor penetration core is arranged within the armor penetration core and emerges forwards in the area of ​​the tip of the projectile after penetrating the armor in the target. It has now been shown that the predetermined breaking point provided for breaking the penetration core after the armor penetration of this bullet may lead to the bullet tearing off at this point during the penetration of the armor, so that the penetration performance of the bullet does not meet all the desired requirements. The object of the present invention is, on the one hand, to increase the penetration performance in the case of heavily armored targets, on the other hand, to make the projectile fully effective even when used against weakly armored targets. In both cases, it should be ensured that the pyrotechnic mass is carried safely behind the armor and is scattered over the target with the projectile fragments. According to the invention, this object is achieved in that the projectile body, which is thickly jacketed at the head, has a conical interior that widens towards the rear and is filled with incendiary material, the wall thickness and hardness of which decreases from front to back in the projectile jacket with a ground screw. In order to achieve an optimal penetration effect, the hardness of the z. B. provided with an obtuse-angled point bullet jacket in its front third mainly about 65 HRC and sinks in its middle third] from 65 to about 35 HRC, while the bullet jacket can be soft in its rear third. A ground screw made of light metal, for example high-strength aluminum, is primarily used as a driving block for splitting the bullet jacket, which is already compressed radially from the outside when the armoring is penetrated and thus broken in the structure. The weight saving due to the aluminum ground screw can be offset by a higher amount of steel in the head of the projectile body. With the same total weight, the bullet achieves a penetration rate that is 25% higher. Even with sheet steel walls with a thickness of 3 to 5 millimeters, perfect dismantling with double fire, i.e. H. Impact fire caused by the incendiary device in the hood and target fire behind the armor caused by the incendiary material in the penetration core. But even armor plates with a wall thickness of 25 mm can still be shot through smoothly by the 20 mm bullet. The bullet is therefore highly effective and versatile. Details of the invention emerge from the description of the exemplary embodiment shown in the drawings. The figure shows a longitudinal section through the projectile according to the invention and next to it the hardness curve of the projectile from the tip to the bottom. The projectile, which has an obtuse-angled projectile tip 1, has a very thick jacket in the head part. Its projectile jacket 2 decreases approximately evenly from the front to the rear, so that, with a cylindrical outer shape, a conical inner cavity 3 is obtained, which is filled with incendiary material 4. The interior 3 is closed to the rear by a floor screw 5 made of high-strength light metal, in particular aluminum or an aluminum alloy. On the outside, the bullet jacket 2 is provided with a guide ring 6. A hood 7, which is filled with incendiary material 8, is attached to the projectile. The edge of the hood 7 is pressed into a groove 9 in the projectile jacket 2. When impacting a target, in the same way as with the projectile according to the main patent, the incendiary material 8 of the hood 7 creates fire in front of the armor, the incendiary mass 4 in the penetration core 1, 2 fire in the target behind the armor. The 20 mm bullet penetrates armor plates with a wall thickness of 25 mm, but double fire is already generated with sheet steel walls of 3 to 5 mm, i.e. H. Fire in front of and behind the armor plate. This effect can be controlled by varying the hardness curve. The harder the stern of the projectile body is left, the easier it is for the body to break from the stern after passing through a thin plate. While in the case of the projectile according to the main patent the point breaks open during or after the armor plate penetration, in the case of the present projectile the point remains intact during the penetration. The full force of the projectile including incendiary material drives the dimensionally stable, thick-walled projectile tip 1 through the armor. When the bullet jacket 2 is forced through the penetration opening produced by the tip 1, which has a diameter, as has been shown, smaller than the bullet diameter, its structure and internal strength are greatly influenced. It results from the fact that the bullet jacket 2, while it tears open from back to front into a few large, strip-shaped splinters when it hits thin targets, after penetrating thick-walled targets from the groove 9 - which forms the predetermined breaking point - to the upper curve of the interior 3 tears off and is broken down into many small splinters. The ground screw 5 acts, since the bullet jacket 2 is strongly braked on impact, as a piston plunger which presses on the incendiary material 4 after the armor penetration and, following the bullet splinters, spreads it into the target in an approximately conical shape. The splinters form the trailblazers that open fuel tank walls, propellant charge cartridges and the like. The incendiary material attached to or following the splinters, ignited upon impact and the ingress of atmospheric oxygen, creates the desired fire. PATENT CLAIM Fire projectile, in particular tank fire projectile, which has an approximately cylindrical projectile body tapering at the front, according to the patent claim of the main patent, characterized in that the projectile body, which is thickly jacketed at the head, has a conical interior space (3 ), whose wall thickness and hardness decreasing from front to back ** WARNING ** End of DESC field could overlap beginning of CLMS **.

    The 20 mm bullet penetrates armor plates with a wall thickness of 25 mm, but double fire is already generated with sheet steel walls of 3 to 5 mm, i.e. H. Fire in front of and behind the armor plate. This effect can be controlled by varying the hardness curve. The harder the stern of the projectile body is left, the easier it is for the body to break from the stern after passing through a thin plate. While in the case of the bullet according to the main patent the tip breaks open during or after the armor plate penetration, in the case of the present bullet the tip remains intact during the penetration. The full force of the projectile including incendiary material drives the dimensionally stable, thick-walled projectile tip 1 through the armor.
    When the bullet jacket 2 is forced through the penetration opening produced by the tip 1, which has a diameter, as has been shown, smaller than the bullet diameter, its structure and internal strength are greatly influenced.

    The ground screw 5 acts, since the bullet jacket 2 is strongly braked on impact, as a piston plunger which presses on the incendiary material 4 after the armor penetration and, following the bullet splinters, spreads it into the target in an approximately conical shape. The splinters form the trailblazers that open fuel tank walls, propellant charge cartridges and the like.
