  • a self-separation mechanism remains active until a check of the function of a detonator is completed. If the result is negative, a self-decomposition takes place, which is thus placed at the beginning of the mission.

  • the invention is based on the idea of specifying an ammunition which in a so-called main combat distance does not undergo any external ballistic disturbances which, however, if the target has not been hit, can reduce the velocity much faster. Especially during practice ammunition they have to show as much as possible the same characteristics as the corresponding combat ammunition within the training main combat detachment, but then they can reduce the speed much faster. These requirements are ensured by the fact that after reaching this Trents, Main combat distance, the air resistance of the projectile is increased or the trajectory of the projectile is influenced in such a way that the speed is reduced faster and the trajectory is reduced (shortened). For this purpose, a change is made on the floor, which causes the change in air resistance or the change in Fiug s.

  • the design of the plastic log and the projectile body is made in such a way that the ballistic equality with the introduced combat or practice ammunition is maintained.
  • Tracer light as well as retardation element (s) are designed so that they allow the projectile to fly smoothly over a certain distance (main combat distance). Therefore, according to the distance or time of flight of the projectile, they have a charge with a preset nominal burning time. Due to the hot powder gases when the projectile is fired, the tracer track or the pyrotechnic retardation element (s) are ignited in the projectile body. After leaving the gun barrel on the trajectory of the projectile is fired by the one or more delay elements and their delay lines or by the tracer at the end of the preset burning duration arranged in the projectile body pressure generating charge. As a result of the internal pressure arising in the projectile, the projectile giveaway opens along its predetermined breaking points, thereby changing the aerodynamic resistance of the projectile. This changed air resistance ensures that a predetermined residual flight distance is not exceeded.

Abstract

L'invention concerne un projectile (1, 11, 21), également sous forme de projectile d'exercice, qui d'une part présente une uniformité balistique jusqu'à une distance de combat prédéfinie par comparaison avec des munitions réelles ou d'exercice introduites et, d'autre part, dont la vitesse diminue cependant beaucoup plus vite lorsque cette distance est dépassée, et qui présente par conséquent une portée totale nettement limitée par rapport à la munition introduite. Le projectile (1, 11, 21) comporte un corps de projectile (3, 13, 23), une ogive de projectile (2, 12, 22) ainsi qu'au moins une traînée lumineuse (5, 15, 25) et/ou au moins un élément de décélération (6, 16, 26). L'invention vise à réduire la vitesse ainsi que la trajectoire. À cet effet, une charge (7, 17, 27) générant de la pression est intégrée dans le corps de projectile (3, 13, 23), laquelle charge est en liaison fonctionnelle avec l'au moins une traînée lumineuse (5, 15, 25) et/ou l'au moins un élément de décélération (6, 16, 26). Après la combustion de la traînée lumineuse (5, 15, 25), ou de la charge de décélération à l'intérieur de l'élément de décélération (6, 16, 26), l'amorçage de la charge (7, 17, 27) a lieu, laquelle agit alors sur le projectile (1, 11, 21) de sorte qu'une fois atteinte une durée de vol (t) réglée, la trajectoire du projectile (1, 11, 21) est influencée.
