Definitions
- the invention relates to a spin stabilized artillery projectile with a metallic guide band for transmitting the swirl to the projectile and a rear side arranged by the guide band sealing ring.
- Such artillery projectile is known for example from DE 40 00 167 C2.
- the known projectile has a multiple annular grooves exhibiting guide band on which the Projectile bottom towards a plastic existing sealing ring, which also referred to as Obturatorring is, is arranged.
- This sealing ring serves to improve the sealing of the Bullet against the high pressure propellant gases and is usually non-positively attached by shrinking on the floor.
- the sealing ring is guided in such a circumferential groove that he in accordance with high centrifugal forces is displaced radially outward. This can it at firing within the corresponding barrel to damage of the sealing ring come through cuts through the train-field profile of the pipe. After the projectile has left the barrel, the centrifugal force, that parts of the sealing ring as a high-energy splitter to a hazard in Lead the radius of the gun. Besides, due to the non-reproducible Condition of the sealing ring after leaving the barrel outside ballistic Disruptions occur.
- the present invention has for its object to provide a spin stabilized artillery projectile of the type mentioned, in which damage or destruction or stripping of the sealing ring during insertion of the projectile into the cargo space of the corresponding weapon and the pipe passage safely prevented and its sealing function is not negative being affected.
- a radial lifting of the sealing ring from the groove should be avoided.
- the invention of the idea is based, as a sealing ring not to provide a plastic ring, but a preferably made of copper metal ring, which is arranged in an annular groove of the projectile and can rotate freely with respect to the projectile (so-called. Slipping metal seal).
- the sealing ring is guided by a dovetail-shaped groove, so that even at high projectile speeds lifting of the sealing ring from the groove is reliably avoided.
- the metal gasket does not take any groin force when passing through the pipe of the corresponding projectile on, and since no lateral surface pressure is applied, it comes to none Wear of the incision profiles, so that ensures a reliable seal of the powder gases is.
- the same material can be used as it is is used for the guide band of the corresponding projectile.
- copper-tin alloys e.g., CuZn10 have proven useful.
- the figure shows the cross section of a spin-stabilized artillery projectile according to the invention 1 in the region of his existing example of copper guide tape 2, wherein the guide band 2, in the direction of the longitudinal axis 3 of Bullet 1 seen from three web-shaped guide belt parts composed.
- Rear side of the guide band 2 is according to the invention a slipping sealing ring 4 made of copper in an annular groove. 5 arranged, which formed as a dovetail-shaped guide is.
- a slipping sealing ring 4 made of copper in an annular groove. 5 arranged, which formed as a dovetail-shaped guide is.
