  • the resulting at the launch of the practice projectile projectile charge gases reach in this full-caliber training projectile in the interior of the tubular tail body and act to accelerate the practice projectile on the rear-side portion of the headboard, which limits the interior geunterkopf proof.
  • a per se known sealing system is on the outside in the rear third of the tubular region of the tail body arranged. This consists essentially of a recessed into the outer surface of the tail body annular groove into which engages an existing plastic sealing ring.
  • DE 35 32 41 1 C2 deals with a trained as a dummy ammunition hollow charge projectile with caliber-identical stabilizer, which has a front and a rear explosive chamber and which is provided at the end face of the projectile casing with a firing rod.
  • the connection plate is in this case formed with the firing rod and the rear explosive chamber forming part of the projectile casing as a forging and welded to a cylindrical tube made of the same metal as the central part.
  • a support disk is arranged, which prevents the projectile shell from being compressed by the high firing pressure, so that the projectile shell requires only a small wall thickness.

  • the conical part is provided in the circumferential direction with spaced-apart projections, which sit firmly and extend radially.
  • a sliding guide band is known, wherein in particular a method for providing a KE ammunition, such as subcaliber bullet, with the sliding guide band is shown.

  • the invention is based essentially on the idea to dispense with a sealing system in the tubular portion of the tail body and form the tail body partially underkalibrig, so that the firing charge gases produced at the launch of the training projectile also act on the outside of the side wall of the tubular tail body and thus the on the Outside of the tubular tail body acting pressure counteracts the acting on the inside of the side wall of the exercise projectile internal pressure.
  • a guide is provided in particular for reducing an initial donation of the exercise projectile in the rear region of the tail body, which comprises a plurality of evenly distributed over the circumference of the tail body arranged, web-shaped guide elements.

  • the guide should comprise at least three web-shaped guide elements.
  • the web-shaped guide elements can advantageously be provided on their outer end in each case with a thin layer or a plate made of plastic or of a viscous paint.

  • this layer 9 serves to relieve the cardboard parts (sleeve jacket, sleeve cover) of the cartridge provided with a combustible sleeve, which accommodates the training projectile according to the invention.
  • this layer 9 is stripped off or strongly compressed, so that it does not hinder the aerodynamics of the training projectile 1 when leaving the gun barrel.

  • a sealing ring 1 made of plastic engages in a circumferential groove-shaped recess (annular groove) 12 in the rear-side area of the head part 2.
  • This sealing system 10 is around a conical seal, wherein the width of the annular groove 12 is greater than the width of the sealing ring 1, so that the sealing ring 11 is displaceable axially to the projectile tip at a pressurization by the propellant gases within the annular groove 12. Due to the conical configuration of the Nuiengrundes the annular groove 12 causes the axial displacement of the sealing ring 11 and a radial expansion of the sealing ring 11, so that there is a permanent Lid réelle between the exercise floor 1 and the inner wall of the gun barrel.

Abstract

L'invention concerne un projectile d'exercice de gros calibre (1) comportant une partie ogive (2) pleine et un corps d'empennage (3) tubulaire dans le prolongement arrière de la partie ogive (2). L'invention vise à assurer de manière économique la résistance au tir de ce projectile. A cet effet, le corps d'empennage (3) est conçu de sorte que les gaz de charge propulsive dégagés lors du tir du projectile d'exercice (1) agissent également sur la face externe (5) de la paroi latérale (6) du corps d'empennage (3) tubulaire. Un guide est prévu dans la zone arrière du corps d'empennage (3) et comporte plusieurs éléments de guidage (7) uniformément répartis sur la circonférence du corps d'empennage (3), ces éléments de guidage étant (7) conçus comme des éléments d'écartement. En outre, pour éviter tout écoulement du gaz de charge propulsive sur la paroi extérieure du projectile d'exercice (1) à l'intérieur du canon d'arme, un système d'étanchéité (10) est disposé dans la zone de la partie ogive (2) pleine du projectile d'exercice (1).
