Definitions

  • the invention relates to a projectile with a discharge charge for discharging a payload.
  • the discharge charge In the case of a projectile, the discharge charge is intended to develop gas under high pressure for a comparatively long time in order to safely push out the payload. This requires safe insulation at the start of the combustion of the exhaust charge.
  • the discharge charge is accommodated in a thick-walled aluminum cup.
  • the bowl bursts into coarse fragments when it burns. These can damage the payload to be ejected.
  • EP-A-0 271 480 faulty ignition of the delay element by torn off aluminum sections is to be prevented.
  • the ejection charge is arranged in a steel bowl which has a plurality of openings in the bottom, that is to say only in the longitudinal direction, the openings being covered with an aluminum foil. The openings are offset with respect to a central ignition opening of a subsequent delay element. Faulty ignition of the delay element cannot, however, be ruled out due to the free distance between the bottom of the cup and the delay element.
  • the object of the invention is to propose a projectile in which the ejection charge develops a high enough pressure to eject the payload, but does not burst its shell into fragments which can damage the payload.
  • the receiving body forms the necessary insulation for the discharge charge.
  • the wall parts of the weak-walled cup located in the area of the openings are pushed through the openings as a result of the pressure development, and the developing propellant gas flows through the openings and leads to the ejection of the payload.
  • the pressed-through, small wall parts of the bowl are harmless for the payload.
  • FIG. 1 shows the head area of a projectile in longitudinal section.
  • a projectile jacket (1) has an internal thread (2).
  • a cylindrical receiving body (3) with a thread (4) is screwed into the internal thread (2).
  • the receiving body (3) protrudes into a pressure chamber (5) of the projectile jacket (1).
  • the receiving body (3) is thick-walled and designed so that it is not destroyed when an ejection charge burns up.
  • a plurality of openings (6) are provided on the receiving body (3) and are distributed in the longitudinal direction and in the circumferential direction on the receiving body (3).
  • the receiving body (3) has a bottom (7) into which a piece of felt (8) and an intermediate plate (9) are inserted.
  • An ejection charge (10) is inserted into the receiving body (3) and contains an NC propellant charge powder (12) in a weak-walled bowl (11).
  • the bowl (11) consists, for example, of aluminum or cardboard.
  • the cup (11) is closed at the top with a lid (13) made of aluminum or cardboard.
  • An ignition device (14) is screwed into the internal thread (2) adjacent to the cover (13).
  • a payload (15) to be ejected is mounted on the floor (7) in the projectile jacket (1).

Claims (5)

  1. Projectile comprenant une charge d'éjection pour éjecter une charge utile (15), dans lequel un corps de réception (3) destiné à la charge d'éjection (10) est fixé dans le projectile (1), corps qui résiste au développement de la pression lors de la combustion de la charge d'éjection (10), le corps de réception (3) comprend plusieurs ouvertures (6) qui sont recouvertes par un élément (11) pouvant être creuvé et par lesquelles sort le gaz d'entraînement dégagé par la combustion de la charge d'éjection (12), les ouvertures (6) sont réparties en direction longitudinale et en direction périphérique sur le corps de réception cylindrique (3), l'ouverture (6) étant obturée en direction longitudinale au moyen d'une plaque intermédiaire (9) et d'un élément en feutre (8), et la charge d'éjection (10) étant disposée dans le corps de réception (3) dans une coupelle (11) à paroi de faible résistance et pouvant être crevée.
  2. Projectile selon la revendication 1, caractérisé en ce que le corps de réception (3) est fixé dans l'enveloppe (1) du projectile au moyen d'un filetage (4).
  3. Projectile selon la revendication 1, caractérisé en ce que la coupelle (11) s'appuie par l'intermédiaire de l'élément en feutre (8) et de la plaque intermédiaire (9) sur un fond (7) du corps de réception (3) et en ce qu'un dispositif d'allumage (14) est disposé à proximité de la charge d'éjection (10) à l'extrémité du corps de réception (3) qui est ouverte et à l'opposé du fond (7).
  4. Projectile selon les revendications 1 et 2, caractérisé en ce que le dispositif d'allumage (14) et le corps de réception (3) sont vissés dans le même filetage (2) de l'enveloppe (1) du projectile.
  5. Projectile selon la revendication 1, caractérisé en ce que la coupelle (11) est constituée en aluminium ou en carton.
