Definitions
- the invention relates to an explosive projectile with the features specified in the preamble of claim 1.
- Bullets fired from missiles are subject to high launch accelerations. This applies in particular for explosive projectiles which can be fired from tank cannons, in which the launch acceleration is of the order of magnitude of 36,000 g.
- TNT bound explosive charges to apply to the inner surface of the walls of the explosive charge receiving cavity a paint, which connects after the introduction of the explosive charge into the cavity with the explosive charge and for an adhesion of the explosive charge to the inner Surface of the usually made of steel projectile body provides.
- the invention has for its object to provide an explosive projectile of the type mentioned above, which with high launch acceleration (> 15000 g) shot can be and in which even when using plastic-bound insensitive explosive charges is not to be feared that it comes due to the high acceleration to an explosion in the barrel and stress cracking in the explosive charge is avoided in temperature shock tests.
- the invention is essentially based on the idea of performing a total separation of the charge from the inner wall or, alternatively, by means of a partial coating with non-stick material, to minimize the "setback" effect Due to the now only partial adhesion / non-adherence of the explosive charge, the setback effect is even avoided and the different expansion behavior is manageable.
- a silicone layer is applied at least in some areas between the explosive charge and the inner surface of the projectile body, which prevents adhesion of the explosive charge to the projectile inner surface for this area.
- the silicone intermediate layer is arranged in the region of the inner surface of the cavity facing the projectile tip of the projectile and / or in the region of the inner surface of the cavity facing the projectile tail of the projectile.
- the layer thickness of the silicone intermediate layer should be at least 10-1000 ⁇ m, preferably 100-200 ⁇ m, in order to adhere sufficiently strongly to the steel inner wall of the projectile. Characterized in that at least in partial areas between the explosive charge and the inner surface of the projectile body, the silicone intermediate layer is provided, on the one hand ensures a sufficient positional fixation of the explosive charge with respect to the adjacent inner surface of the projectile body (2) and on the other hand a large part of the tensions between the Projectile body and receives the explosive charge in a thermal shock test, cracking in the explosive charge at Verschuss is certainly avoided.
- a spin-stabilized explosive projectile which can be fired, for example, from a 155 mm caliber howitzer, can be fired.
- the explosive projectile 1 comprises a projectile body 2 made of steel, which has a cavity 4 extending in the direction of the longitudinal axis 3 of the projectile 1. In the cavity 4 is a known plastic-bound insensitive explosive charge. 5
- a silicone intermediate layer 9 with a layer thickness of preferably 100-200 ⁇ m is arranged at least in partial regions 7, 8 (in the depiction shown in FIG Embodiment, about 56% of the inner surface 6 of the projectile body 2 are covered by the silicone intermediate layer 9).
- the silicone intermediate layer 9 is arranged in the projectile tip 10 of the projectile 1 facing portion 7 of the inner surface 6 of the projectile body 2 and / or in the projectile tail 11 of the projectile 1 facing portion 8 of the inner surface 6 of the projectile body 2. Only in the areas in which no silicone intermediate layer 9 is provided, there is an adhesive connection between the projectile body 2 and the explosive charge. 5 LIST OF REFERENCE NUMBERS
