Definitions

  • the invention relates to a warhead with an explosive charge enclosing Warhead casing.
  • the charges consist of the known Warheads of a unitary material chosen such that the when the charge detonates, splinters generated in a particular direction (e.g. Flight direction) have a predetermined acceleration and angular distribution. Splinters flying in a different direction (e.g., perpendicular to the direction of flight) become Although then also correspondingly high speeds, although such a high acceleration this splitter is not necessary.
  • the invention is based on the object, a warhead of the aforementioned Kind to reveal, on the one hand in detonation of its explosive charge a high acceleration the flying in the direction of splitter causes and on the other hand a less acceleration of splinters flying sideways from the warhead caused and / or in the side of a relatively strong pressure wave is generated.
  • the invention is based essentially on the idea, not a uniform charge to arrange in the shell of the warhead, but at least two different To provide charges.
  • the points in the area of the top of the warhead arranged, e.g. from octogen (HMX) existing first partial charge a high Detonation on, around the arranged before this partial charge heavy metal splitter (preferably WSM-ball splitter) at detonation of the explosive charge very much fast forward (in the direction of flight) to accelerate.
  • this partial charge heavy metal splitter preferably WSM-ball splitter
  • This partial charge is only for one Acceleration of the lateral flying away e.g. Steel splitter required.
  • explosives can also be used as the second charge can be used, which only generates a strong lateral pressure wave.
  • the first partial charge of a mixture of 70-90 vol% octogen (HMX) and 10-30 vol% of an inert plastic binder e.g., hydroxyl terminated polybutadiene (HTPB)
  • an inert plastic binder e.g., hydroxyl terminated polybutadiene (HTPB)
  • RDX hexogen
  • both partial charges should use the same binders be used.
  • the second partial charge should be a metal powder (e.g., aluminum powder). blended to create a blast effect.
  • a metal powder e.g., aluminum powder
  • the warhead 1 is a ballistic warhead fireable from a gun referred to, which is to be used against bunkered positions and while sideways from the respective position vehicles should also destroy.
  • the warhead 1 comprises a warhead casing 2 made of steel, a front side of the warhead casing arranged proximity fuse 3, one adjoining the igniter Splinter plate 4 with heavy metal splinters (e.g., WSM balls) and an explosive charge 5.
  • the explosive charge 5 is made up of four, in the direction of the longitudinal axis 6 of the warhead Seen 1, arranged in succession partial charges 7-10 together.
  • the splitter plate 4 adjacent first partial charge 7 consists of a mixture of e.g. 90% HMX and 10% of a HTPB binder system and has a relatively high Guerney constant of 2830 m / s. This serves to make the WSM balls extra special to accelerate high in the direction of flight.
  • the partial charges 8-10 are used to generate and accelerate the destruction the warhead casing 2 resulting splinters flying away from the side of the warhead. For this much less expensive RDX charges are sufficient. Both Splinters may be natural or preformed structural shards act.
  • the RDX partial charges 8-10 can range from area to area have a different composition (e.g., charge 8: 85% RDX and 15% HTPB binder system; Charge 9: 90% RDX and 10% HTPB binder system and charge 10: 70% RDX, 10% HTPB binder system and 20% aluminum powder).
  • the warhead casing 2 becomes a certain one Share filled with the first partial charge 7.
  • the second mixture is poured on the first partial charge, etc.
  • the layered Infusion of various formulations based on the same polymer system then leads to a "tailored" effect (detonation speed) the charge.

Claims (8)

  1. Tête de munition dotée d'une coque (2) de tête de munition qui enferme une charge explosive (5), et qui présente les caractéristiques suivantes:
    a) la charge explosive (5) comprend au moins deux charges partielles (7, 8-10) liées par matière synthétique et adjacentes l'une à l'autre dans la direction de l'axe longitudinal (6) de la tête de munition (1),
    b) la première charge partielle (7) tournée vers la pointe de la tête de munition (1) est constituée d'un explosif dont la vitesse de détonation est plus élevée que celle de la deuxième charge partielle (8-10) et est sélectionnée de telle sorte que lors de sa détonation, on obtienne une accélération axiale d'éclats (4) en métal lourd disposés sur le côté avant de la tête de munition (1),
