Definitions

  • the invention relates to a training projectile according to the preamble of claim 1.
  • a self-supporting hood made of plastic is provided. This hood withstands the forces exerted on the projectile during launch and in flight. However, due to the stability of the hood, there is a risk that the projectile will bounce off the sand floor practically undamaged at flat angles of impact and then fly over the safety area of the shooting range.
  • the object of the invention is to propose a training projectile, the hood of which on the one hand withstands the loads occurring during the feeding and the firing and on the other hand the bounce range is reduced.
  • the support member stabilizes the thin-walled hood axially and radially so that it can withstand the forces that occur during feeding and firing. On the other hand, even at flat angles of incidence and low impingement speeds, the support part deforms so that the hood breaks off. This increases the flow resistance of the parts so that the bounce range is reduced.
  • Another advantage of this practice floor is that a particularly thin-walled, inexpensive hood can be used, since its stability, which is low in itself, is increased by the support part.
  • a practice projectile has a projectile body (1) made of steel, which is provided with a guide band (2).
  • the projectile body (1) is provided with steps (3) on the front side and, viewed in isolation, has a high air resistance.
  • the projectile body (1) is provided with an axial bore (4).
  • the projectile body (1) On the projectile body (1) is a comparative screwed thin-walled ogiven-shaped hood (5), which consists for example of aluminum.
  • the projectile body (1) forms together with the hood (5) a projectile whose ballistic values correspond to those of sharp projectiles.
  • a support part (7) is arranged in this.
  • the support part (7) is made of plastic, such as polyethylene, polyurethane or polyamide.
  • the support part (7) has a pin (8) which is inserted into the bore (4).
  • the support part (7) is provided with four webs (9) which are arranged in a star shape (see FIG. 3). Only three webs (9) or more than four webs (9) can also be provided.
  • the webs (9) have outer edges (10), on the course of which the inner shape of the hood (5) is adapted.
  • the webs (9) rest with rear edges (11) in the vicinity of the pin (8) on the front of the projectile body (1).
  • the functionality of the described device is approximately as follows:
  • the support part (7) is held radially by the pin (8) on the projectile body (1). It is supported axially on the rear edges (11) of its webs (9).
  • the outer edges (10) support the hood (5) both radially and axially.
  • the supporting part (7) takes on axial and radial forces acting on the hood (5).
  • the support part (7) also dampens vibrations of the hood (5).
  • the webs (9) are deformed on account of the elasticity of the plastic and their shape, so that the hood (5) breaks off from the projectile body (1).
  • the then effective air resistance of the projectile body (1) is so high that the projectile body (1) flies only a comparatively small distance.
  • surface parts can be arranged in the area of its steps or on the support part (7), which open or open when the hood (5) is broken off.

Claims (4)

1. - Projectile d'exercice comportant une ogive (5) à paroi mince, en matière plastique, qui est placée sur un corps de projectile (1), le corps de projectile (1) comportant, à l'intérieur de l'ogive (5), des gradins (3) et un perçage axial (4) dans lequel est inséré un corps complémentaire (7) avec un tenon (8), dans lequel le corps complémentaire (7) se situe dans un espace libre (6) compris entre le corps de projectile (1) et l'ogive (5), caractérisé en ce que le corps complémentaire est un élément d'appui (7) en matière plastique avec nervures (9) disposées en étoile dont les bords extérieurs (10) s'appliquent contre l'ogive (5) et en ce que le côté frontal du corps de projectile (1) est tel que sa résistance à l'air est importante par rapport au projectile.
2. - Projectile d'exercice selon la revendication 1, caractérisé en ce que l'élément d'appui (7) s'applique contre le corps de projectile (1), par des bords (11) arrière des nervures (9), dans la région du tenon (8).
3. - Projectile d'exercice selon la revendication 1, caractérisé en ce qu'il est prévu, sur le corps de projectile (1) ou sur l'élément d'appui (7), des éléments plats qui, après rupture de l'ogive (5), augmentent la résistance à l'air.
4. - Projectile d'exercice selon la revendication 1, caractérisé en ce que les bords extérieurs (10) des nervures (9) s'appliquent sur toute leur longueur contre l'ogive (5) et soutiennent celle-ci axialement et radialement.
