Definitions
- the present invention relates to a deformation and / or partially dismantling projectile.
- the invention also relates to a method for producing a deformation and / or partially dismantling projectile.
- Bullets are usually made of relatively soft lead that is encased in a harder material such as copper or a copper alloy such as tombac.
- the lead gives the bullet the high specific weight that is important for its ballistic performance.
- the bullet jacket protects the barrel of the rifle from lead and enables higher bullet speeds, since the bullet can still follow the rifle barrel's rifling trajectories and fields through which it is rifled, even at high speed, thanks to the harder outer layer.
- the core In the case of partial jacketed projectiles or partial fragmentation projectiles, the core is not enclosed by jacket material on the front of the floor and is exposed.
- the bullet tip When hitting a target, the bullet tip deforms due to the high pressure on impact and when penetrating the target.
- the projectile can deform in the shape of a mushroom (mushrooming) or at least partially deform.
- the bullet can deliver its energy to the target medium much more effectively than a full jacketed bullet, in which the jacket completely surrounds the core, but has a lower penetration rate.
- Such bullets are used in particular as hunting bullets, since they lead more reliably to faster death of the game than full jacketed bullets due to the effective energy release in the body of the game when properly shot.
- Partial dismantling bullets are usually designed in such a way that they dismantle in a controlled manner except for a defined residual body.
- the suction effect of the rest of the body ensures that the fragments of the front, dismantled core part largely leave the target.
- Deformation bullets mushroom when they hit the target and remain stable in mass.
- Deformation bullets designed so that they hardly lose weight in the target. The effect is primarily achieved by increasing the cross-section of the evenly mushrooming bullet and the constant weight.
- DE 10 2015 001 559 A1 discloses a lead-free partial fragmentation bullet.
- the projectile has an essentially hollow-cylindrical jacket into which a two-part core is pressed.
- All lead-free compressible materials are proposed as core materials, for example tin, zinc or granulates.
- core materials for example tin, zinc or granulates.
- the lead-free projectiles do not have the same efficiency as lead-containing projectiles.
- the tin material used tends to tear when the bullet hits the target, so that no deformed residual body remains.
- the pressing of the core in the projectile jacket does not fulfill the desired function, in particular not the required permanent, fixed connection of jacket and core. When it hits its target, there is a risk that the pressed core will detach from the jacket, so that no deformed residual body remains.
- the object of the present invention is to improve the disadvantages of the known prior art, in particular to improve a deformation and / or partial fragmentation projectile and a manufacturing method for a deformation and / or partial fragmentation projectile so that its deformation and / or fragmentation upon impact a target leaves behind a defined, deformed residual body.
- Partial fragmentation bullets are generally designed in such a way that when the bullet hits a target they break down in a controlled manner down to a defined residual body.
- Deformation bullets are usually characterized by a stable, controlled deformation.
- the deformation and / or partial fragmentation projectile comprises a jacket.
- the jacket can be implemented as a rotationally symmetrical, in particular essentially cylindrical, hollow body which is designed to be open towards one end face.
- Metals in particular hard metals such as copper, copper alloys, for example tombac, can be used for the jacket.
- the jacket can, for example, have a preferably circumferential tear-off edge on its outer circumference, which can be arranged, for example, approximately at the transition between the ogive on the front of the floor and the rear of the floor. When the projectile hits a target, the tear-off edge can help the jacket to deform and / or break apart in the area of the ogive up to the tear-off edge.
- the ogive of the shell on the projectile front is torn off from the stern when the projectile hits a target, specifically along the spoiler edge.
- the tear-off edge can, for example, be oriented essentially perpendicular to the longitudinal axis of the bullet and also serve to determine the deformation and / or decomposition behavior of the deformation and / or partial decomposition bullet, in particular to limit deformation and / or decomposition of the bullet.
- the deformation and / or partially dismantling projectile further comprises a two-part core arranged within the casing, with a core part on the projectile front side and a core part on the projectile rear side.
- the front-end core part is arranged in the jacket or dimensioned such that a front-end core tip of the front-end core part protrudes from the jacket and / or is not surrounded by a jacket. Both the core part on the projectile rear side and the core part on the projectile front side can rest completely circumferentially and along their entire outer surface on an inner circumference of the casing.
- the core parts can be arranged in the jacket in such a way that the floor-side core part rests on a floor-side floor of the jacket and / or that the projectile-front core part rests over the entire surface of the floor-side core part.
- a dividing plane between the core part on the storey side and the bow-side core part is formed by a respective end face of the core parts, in particular a front face of the tail-end core part and a rear end face of the nose-end core part.
- the dividing plane between the core part on the rear of the storey and the front of the storey can for example be conical and oriented in the direction of the rear of the storey, ie from the inner circumference of the jacket conically in the direction of the The projectile stern up to a cone tip, which lies, for example, on an axis of rotation of the jacket, form. It was found that in the case of deformation and / or partially dismantling projectiles of the generic type, the tear-off edge is to be provided in the area of the dividing plane between the core parts.
- an axial position of the tear-off edge on the projectile jacket with respect to the axial position or axial extension of the parting plane between the core parts and thus can be matched to a dimensioning of the core parts.
- the tear-off edge lies between a start of the conical parting plane lying on the inner circumference of the jacket and an end of the parting plane that is on the rear of the floor and is designed as a tip of the cone. It has been found that such a positioning of the tear-off edge in relation to the parting plane between the core parts leads to reliable deformation and / or partial disintegration when the projectile hits a target.
- the core is fastened in the jacket in such a way that the core part on the projectile rear side is fastened more strongly to the jacket than the core portion on the projectile nose. It was found that the less strong fastening of the projectile-side core part in the jacket ensures reliable tearing of the projectile-side projectile section, in particular the projectile-side core part and / or the ogive section of the jacket surrounding the projectile-side core part, when the projectile hits a target.
- the stronger fastening of the core part on the projectile rear reinforces the connection or the fastening of the core part on the floor rear side to the jacket, so that it is ensured that the core part on the floor rear side does not become detached from the jacket when the projectile hits the target and that a defined remaining projectile body remains can realize an effective energy release in the target.
- the inventive measure of stronger fastening of the rear-end core part in the jacket compared to the front-end core part means that additional, in particular constructive, measures to increase the connection between the rear-end core part and jacket can be dispensed with.
- the front-end core part is fastened to the jacket in such a way that the front-end core part can detach from the jacket when the projectile hits a target. Furthermore, the core part on the projectile rear side can be fastened to the jacket in such a way that the core part on the projectile rear side remains fastened to the jacket when the projectile hits a target.
- the core part on the projectile rear is fastened to the jacket at least 5% more strongly than the core part on the projectile front.
- the core part on the projectile rear side is preferably fastened to the jacket at least 10%, 15%, 20%, 25% or at least 30% more strongly than the core part on the projectile front.
- the core part on the projectile rear side is fastened to the jacket at least 40%, 50%, 60%, 70%, 80%, 80% or at least 100% more strongly.

- the core part on the projectile rear side can also be made of tin, zinc or alloys thereof.
