Definitions
- the invention relates to a connection between the sabot jacket and the sabot rear of a sabot projectile with a circumferential groove on the sabot rear, into which a flange of the sabot jacket protrudes, to form a connection between the sabot jacket and sabot rear, which on the one hand resists the mechanical forces during firing and on the other hand is gas-tight.
- connection between the sabot jacket and the sabot tail is designed in such a way that with large mechanical forces and high gas pressure there is a risk that the sabot jacket may detach itself prematurely from the sabot when the projectile is fired or that the connection is not up to the high gas pressure, ie is not sufficiently gas-tight.
- a higher cadence of the firearm results in greater acceleration and deceleration forces when the cartridges are fed to the weapon, which means that there is a risk that the connection between the sabot rear and the sabot jacket will be damaged before the bullet enters the weapon.
- the cartridge case is attached to a circumferential groove of the projectile or the sabot rear.
- this connection is at risk as long as that Projectile after the propellant charge is ignited in the cartridge case, the free flight distance is covered and the outside of the guide ring is not yet supported by the tube wall and the cables. In the tube itself, the guide ring is pressed against the sabot tail.
- the object is achieved to create a connection between the sabot jacket and sabot rear end, which can withstand great mechanical forces and large gas pressure when the sabot projectile is fired.
- connection according to the invention is characterized in that the sabot tail has a second circumferential groove in addition to the said circumferential groove and that the sabot jacket also has a second flange in addition to the flange mentioned, one flange serving for sealing and the second flange for fastening.
- the side walls of the one circumferential groove are preferably parallel to one another and inclined at an angle of 75 ° to the front relative to the projectile axis.
- the side walls of the other circumferential groove are preferably inclined at an angle of 75 ° forwards or backwards relative to the projectile axis.
- the sabot projectile consists of a projectile body 10, a sabot rear 11 and a sabot jacket 12.
- a ballistic hood 13 is placed on the projectile body 10.
- a hard metal or a tungsten alloy is used for the projectile body 10, for example.
- the sabot tail 11 is made of light metal, for example, and the sabot jacket 12 is e.g. made of plastic.
- the sabot jacket 12 usually consists of three segments which are connected to one another via predetermined breaking points 14. In the drawing Fig. 1 only a predetermined breaking point 14 is visible.
- the sabot jacket 12 also has cutouts 15 and a guide band 16.
- the projectile body 10 has two circumferential grooves 17, which are used to fasten the sabot rear 11.
- the sabot tail 11 is provided with six tongues 18 which protrude with cams 25 into the circumferential grooves 17 of the projectile body.
- the structure of the sabot projectile described so far is known.
- the invention relates to the connection between the sabot jacket 12 and the sabot rear end 11.
- the sabot rear end 11 has a first circumferential groove 19 which is formed by two side walls 21 and 22 which are parallel to one another. These side walls 21 and 22 are inclined forward at an angle of 75 ° with respect to the projectile axis. There is also a second circumferential groove 26 which is formed by two side walls 24 and 28, one side wall 24 being inclined rearward at an angle of 75 ° and the other side wall 28 being inclined forward by the same angle of 75 °.
- a reliable, gas-tight connection is achieved through the first circumferential groove 19, and a reliable connection that withstands mechanical forces is achieved through the second circumferential groove.
- a corresponding flange 20 of the sabot jacket 12 projects into the first circumferential groove 19 and a corresponding second flange 27 of the sabot jacket 12 projects into the second circumferential groove 26.
- the side walls of the circumferential grooves 19 and 26 do not have to be inclined. They can also be perpendicular to the floor axis. Wedge-shaped or dovetail-shaped circumferential grooves are conceivable.
