Definitions
- the invention relates to a protective device for protection against projectiles, ammunition and other projectiles.
- Out-of-area operations will employ a variety of light and medium armored vehicles.
- the armor of these vehicles must be able to withstand various threats and still be as light as possible. Preference is given to armor, which are also used on smaller vehicles.
- a pure solution of the protection by armor steel is not system compatible for all vehicles. Armor steel in turn is too heavy, so that a pure armor steel solution within permissible vehicle weights is not possible.
- EFP Explosively Formed Projectiles
- EFP are part of the penetration IED and usually act laterally on the vehicle.
- parallel multi-flight in which several projectiles impinge on different vehicle locations at the same time
- serial multi-flight in which the same location is hit several times in succession.
- the EFP often penetrate conventional armor due to their mass and speed.
- the object of the invention is to provide a system-compatible protection in particular light vehicles, such as wheeled vehicles, which forms a sufficient protection especially against EFP.
- the invention is based on the idea to provide an arrangement of strips of different materials, at least two different, wherein the thickness / depth of the (single) strip is significantly greater than the height and the height of the strip is preferably half as large as that Caliber of the EFP flight projectile.
- the adjacent strips should have materials of significantly different strengths.
- the distance (formed by the softer strips) between the two harder strips to each other, however, should be smaller than the caliber.
- the harder strips do not have to have the same material.
- the orientation of this sandwich structure is such that the material layers are superposed to the direction of action. This ensures that when a designed in the direction of protective projectile projectile occurs on the protective structure, it penetrates deeper due to the different materials in the softer than in the adjacent harder, thus shears and can not slide straight through the protection.
- ceramic such as SiC, AI203, B4C
- steel and plastic polyethylene, polypropylene, polyamide
- ceramic and plastic but also steel, aluminum and ceramic, etc. conceivable.
- the starting point is that the projectile impinges on at least two materials of different materials, so that a faster entry of the projectile through the softer material takes place while the harder material slows down the projectile, and the projectile is stopped by the depth of penetration or depth of protection.
- the projectile hangs and offers a standalone obstacle to any subsequent projectiles.
- the mechanism of cutting the projectile the penetration rate is significantly reduced in the ballistic materials, so that compared to steel armor or other protective structures, the greater mass and volume efficiency is achieved.
- the sole figure shows the construction of a protective arrangement or protective device 10, wherein 1 denotes a first strip 1 made of a material A and position 2 a second strip made of a material B (lower partial view in FIG. The depth of the strips is denoted by - 1 - and the respective height of the strips 1, 2 with - h -.
- the shot direction is here designated from right to left with the arrow BR.
- the depth and the height of the strips are to be chosen in accordance with the respective threat.
- the depth of the protective structure should be about 30 mm to 50 mm and the height (thickness), for example, 15 mm.
- the thickness of the individual strips can be selected within the scope of the specification, but should preferably be the same for a simple production of the protective structure 10.
- the forming projectile 5 hits the protective arrangement 10, it will slide faster through the softer material (A, B, C) than through the harder material.
- the forming projectile 5 is cut in its direction of penetration and deflected and remains hanging in the protective structure 10.
- the idea can also be used against medium-caliber projectiles, since without much effort, such a protection arrangement 10 can be used for example as protection level four (4).
- the protective device 1 is not rigid, but slidably mounted. In the case of moving objects in particular, this has the advantage that the protective device can change its position relative to the vehicle and thus subsequent projectiles 5 by means of its own acceleration or various other changes in movement.
