Definitions

  • the invention relates to a spin-stabilized artillery shell according to the preamble of Claim 1.
  • Such an artillery projectile is known for example from DE-A-40 00 167.
  • the known projectile has a guide ring having a plurality of ring grooves on which to An attachment ring, e.g. made of polyamide 6, and towards the floor Plastic sealing ring, which is also referred to as an obturator ring, arranged are.
  • This sealing ring serves to improve the sealing of the projectile against the high pressure propellant gases and is usually non-positive attached to the projectile by shrinking.
  • a spin-stabilized projectile with a guide band is known from CH-A-17 978, which, seen in the direction of the longitudinal axis of the projectile, the swirl transmission of the projectile causing the guide band section and one has a section adjoining this guide band section at the rear, which has an annular groove with a holding device for a plastic sealing ring.
  • a disadvantage of this known floor is, among other things, that the attachment of the Guide tape on the floor due to the integrated holding device for the sealing ring requires an additional fastening groove to be made in the floor.
  • the guide band is relatively complex and already exists Artillery shells can only be done with an extraordinarily great effort be converted because first the entire existing guide band is removed must be provided, the floor with appropriate grooves and only then new guide tape can be applied.
  • the present invention has for its object a spin-stabilized artillery shell of the type mentioned at the beginning, in which damage or destruction or a wiping of the sealing ring when inserting the projectile into the cargo space the corresponding weapon safely prevented in a simple manner and its sealing Function is not adversely affected.
  • the invention is essentially based on the idea that the sealing ring is not on the rear side to be arranged behind the guide belt, but in an annular groove of the guide belt embed. As a result, it is reliably protected against mechanical damage and stripping practically impossible.
  • the defined seating of the sealing ring in the groove guarantees an improvement and a higher one Reliability of the sealing function and thus a reduction in pipe wear.
  • the figure shows the cross section of a spin-stabilized according to the invention Artillery level 1 in the area of his example guide belt made of copper 2.
  • Das Guide belt 2 is set in the direction of the longitudinal axis 3 of the Storey 1 seen - from three web-shaped guide band parts 4-6 together, between which there are two annular grooves 7, 8 are located.
  • the annular groove 8 is made of polyamide 6.6 existing sealing ring 9 arranged, which is in a groove-shaped recess 10 of the projectile wall 11 extends and with this is positively and / or non-positively connected.
  • the sealing ring itself is made with oversize and on one Point separated, the ends of the point of separation such beveled that they are superimposed on the desired inner and outer diameter.
  • the sealing ring is then in the expanded ring groove of the guide tape and the superimposed Permanently seal the ends of the sealing ring with a suitable adhesive connected.
  • the invention is of course not based on the above described embodiment limited.
  • the ring groove for the sealing ring does not have to be so located in the middle part of the guide band, but can also be at another point on the guide band be introduced.
