Definitions

  • the invention relates to a spin-stabilized projectile with a payload that can be ejected according to the preamble of patent claim 1.
  • the invention has for its object to improve the floor structure of a swirl-stabilized payload projectile in such a way that despite the higher ejection pressure required for an ejection process, the detonator arranged in the head of the projectile is not unduly loaded.
  • FIG. 1 shows a schematic sectional illustration of a conventional spin-stabilized payload projectile
  • Fig. 1 shows a schematic representation, partly in longitudinal section, of a conventional spin-stabilized payload projectile 10, which comprises an essentially hollow-cylindrical casing 11 and a floor 12 connected to this casing 11 in a rotationally fixed manner.
  • Payloads 13, which are ejected at a certain point in the trajectory by an ejection charge 15, which is in turn initiated by a detonator 14 arranged in the head of the projectile 10, are arranged in a tight packing one above the other in the casing 11.
  • a mechanically firmer connection between the floor 12 and the shell 11 must be provided in newly developed spin-stabilized payload projectiles with much more massive rear parts are, for the separation of which much stronger ejection charges 15 are required.
  • a pressure-reducing element 20 is arranged between the head igniter 14 and the discharge charge 15, as can be seen from FIG. 2. This pressure-reducing element 20 seals - at least to a large extent - the charge space of the discharge charge 15 towards the head igniter 14, so that no inadmissible pressurization of the head igniter 14 occurs.
  • the pressure-reducing element 20 is designed in the shape of a truncated cone or truncated cone and is arranged between the igniter 14 and the discharge charge 15 on the longitudinal axis of the projectile 10 such that the base of the cone or truncated cone is adjacent to the igniter 14, while the tip of the cone or truncated cone is directed towards the discharge charge 15.
  • An opening 20a is arranged in the tip of the cone or truncated cone of the pressure-reducing element 20, through which an ignition jet for acting on the ejection charge 15 passes when the head igniter 14 is initiated.
  • the discharge nozzle 15a After the discharge charge 15 has been ignited, a rapidly increasing pressure develops in the discharge nozzle 15a, which abruptly deforms the conical or truncated cone-shaped, pressure-reducing element 20 and compresses it into an essentially closed disc, which - at least for a short time - is pressure-resistant Concludes between igniter 14 and the pressurized payload space 16. Due to this pressure-proof seal, the ejection process of the payloads 13 can proceed unhindered, without the leakage or expulsion of the igniter 14, for example gas pressure necessary for separating the floor and expelling the payloads is reduced.
  • the measure provided according to the invention is particularly simple and inexpensive to carry out, so that u. If necessary, even store floors that have already been stored in depots.

Abstract

Un projectile (10) gyrostabilisé à charge utile comprend dans sa partie antérieure une charge d'éjection (15) activée par un détonateur de tête (14) avec un certain retard pour séparer un culot connecté à l'enveloppe (11) du projectile et pour éjecter une charge utile (13). Afin d'éviter que le détonateur de tête (14) ne soit endommagé par la pression des gaz générés par la charge d'éjection (15), un disque conique en tôle (20) est agencé entre le détonateur de tête (14) et la charge utile, sa base étant tournée du côté du détonateur de tête (14) et sa pointe du côté de la charge d'éjection (15). La pointe du disque conique (20) est pourvue d'une ouverture (20a) à travers laquelle passe un jet détonateur émis par le détonateur de tête (14) afin d'activer la charge d'éjection (15). Une fois la charge d'éjection (15) activée, le disque conique (20) se transforme en un disque plat essentiellement étanche aux gaz.
