Definitions

  • the invention relates to a ladder-stabilized full-caliber training projectile which can be fired from a weapon barrel and has a solid head part and a tubular tail body adjoining the head part on the rear side, the training projectile being provided with a sealing system on the circumference.
  • Such a full-caliber training projectile is known from the document DE 10 2010 034 33 A1. It is a large caliber, for example, from a tank cannon with the caliber 120 mm shootable training projectile.
  • the projectile casing itself is designed as a tubular fin body in the aforementioned training projectile, so that a separate shank may be omitted with attached fin assembly.
  • 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 a Plastic engages existing sealing ring.
  • a high internal pressure of the propellant charge gases occurs within the tubular tail body, which strongly acts on the side wall of the tubular tail body, in particular in the region between the sealing system and the head part. This can have an effect on the firing resistance, in particular when using a lighter body of a light metal.
  • the invention has for its object to provide a full-caliber practice bullet of the type mentioned, the firing resistance is ensured in a cost effective manner.
  • the invention is essentially based on the idea to dispense with a sealing system in the tubular portion of the tail body, so that the propellant gases formed at the launch of the training projectile also act on the outside of the side wall of the tubular tail body and thus acting on the outside of the tubular tail body pressure the counteracts the acting on the inside of the side wall of the training projectile internal pressure.
  • a sealing system in the region of the massive head part of the training projectile is arranged.
  • the head part has on its outer side a circumferential area designed as a sealing surface, the outer diameter of which is selected such that the head part itself forms the sealing system when the training projectile is fired in this area.
  • the deviation between the caliber of the weapon barrel from which the training bullet can be fired and the outside diameter of the head part in the region of the sealing surface should preferably be less than 0.2%.
  • the sealing effect of the groove seal is further increased if the sealing surface of the head part has at least three axially spaced-apart, annularly arranged grooves.
  • FIG. 1 shows the longitudinal section through an inventive, consisting of a headboard and a tubular tail body full caliber training projectile with sleeve cover and
  • Fig. 2 is a side view of the exercise projectile shown in Fig. 1 without sleeve cover.
  • FIGS. 1 and 2 denoted by 1 is a ladder-stabilized full-caliber training projectile which can be fired from a gun barrel (not shown).
  • a sleeve cover 2 With the practice floor 1 usually a sleeve cover 2 is connected (Fig. 1), which forms the compound of the training projectile 1 with a propellant charge, not shown, containing the propellant charge.
  • the training projectile 1 comprises a solid head part 3 with a trailing-side arranged tracer body receptacle 4 and a tailpiece body 5 adjoining the head part 3 at the rear.
  • the tubular tail body 5 is designed in such a way that the propellant gases produced during the launch of the training projectile 1 also act on the outside 6 of the side wall 7 of the tubular tail body 5.
  • the tail body 5 is formed underkatibrig and is supported in the charged state of the practice projectile 1 preferably on the rear side via a guide ring, not shown, on the inner wall of the gun barrel. So that upon firing the propellant charge gases can reach the outside 6 of the tail body, the guide ring has a plurality of distributed over the circumference arranged gas passage openings.
  • a sealing system 8 is arranged in the region of the massive head part 3 of the training projectile 1.
  • the head part 3 on its outer side 9 designed as a sealing surface circumferential portion 10, which is bounded by the front end side of the tail body 5, and whose outer diameter is selected such that the head part 3 at the launch of the practice projectile 1 in this area even the sealing system 8 forms.
  • the invention is not limited to the embodiment described above.
  • the massive headboard does not necessarily have to be a solid body. Rather, it can also be a hollow body, if the wall thickness and / or the material (steel, etc.) of the head part are chosen such that the propellant charge gases cause no or no significant deformation of the head part when shooting in the barrel.

Abstract

L'invention concerne un projectile d'exercice de gros calibre (1) comportant une partie ogive (3) massive et un corps d'empennage (5) tubulaire dans le prolongement arrière de la partie ogive (3). L'invention vise à assurer la résistance au tir de ce projectile de manière économique. A cet effet, le corps d'empennage (5) est conçu de sorte que les gaz de charge propulsive dégagés lors du tir du projectile d'exercice agissent également sur la face externe (6) de la paroi latérale (7) du corps d'empennage (5) tubulaire. Afin d'éviter que les gaz de charge propulsive ne s'écoulent sur la face externe du projectile d'exercice (1) à l'intérieur du canon de l'arme, un système d'étanchéité (8) est prévu dans la zone de la partie ogive (3) massive du projectile d'exercice (1), la face externe (9) de la partie ogive (3) présentant une zone (10) périphérique conçue comme surface d'étanchéité dont le diamètre externe est choisi de façon que la partie ogive (3) forme elle-même le système d'étanchéité (8) dans cette zone (10) lors du tir du projectile d'exercice (1). La surface d'étanchéité (10) comprend de préférence des rainures d'étanchéité qui comprennent au moins trois rainures (11) disposées de manière annulaire et axialement espacées les unes des autres.
