Definitions

  • the invention relates to a device for preventing assembly errors during assembly, in particular of smoke bullets.
  • so-called pyrotechnic active masses are brought to the target with so-called fog bullets. This is done, inter alia, by projectiles or a smoke munition. As projectiles artillery and mortar smoke bullets are known. The pyrotechnic active mass of the mists burns off at the bottom, achieving a desired mist effect.
  • the pyrotechnic active mass is housed in individual nebulas. At a certain height, these can then be expelled from the projectile by a discharge charge and at the same time ignited by the combustion gases and particles.
  • the nebulized bodies can also be burned so that they only generate the nebula when the nebulized bodies have hit the ground.
  • the mists are usually cylindrical containers, in particular metal containers, in which a support tube is mounted centrally. This support tube partially absorbs the launch load and allows ignition by the combustion gases and particles of the discharge charge. In this container, the pyrotechnic mass is introduced and sealed with a lid.
  • the invention has the object to show a device with the mounting errors in the assembly of the projectiles are avoided.
  • the invention is based on the idea to ensure by constructive measures on the smoke body that they can not be installed the wrong way round in the floor.
  • the fog bodies are primarily designed so that they are due to their dimensions only in a concrete location can be installed in the floor. With one or more incorrectly installed fog bodies, it is no longer possible after the introduction of the fog body in the projectile casing to mount the floor, a final assembly is not feasible. The error is discovered directly and can be corrected.
  • the smoke bodies mesh with one another during stacking, ie the upper side of a smoke body has an integration cooperating with a lower side of the other smoke body.
  • This can for example be a hole, a groove, a hole, etc. in the top of the other fog body or mist pot or vice versa in a pin or survey on the bottom of a fog body or mist pot.
  • Interlocking devices are also possible, that is to say have a correspondingly shaped cover, in particular in the absence of a support tube, for example.
  • a paragraph on the fog head, etc. are involved, which engages the counterpart during assembly in a groove or recess.
  • the design changes are to be chosen so that even if only one fog body of the floor can not be mounted in case of false appearance.
  • Fig. 3 is a projectile with the fog bodies.
  • Fig. 1 shows a smoke body 1, which has a bore 2 for the implementation of a support tube 3 in this embodiment.
  • the support tube 3 or a part of a lid 4 projects centrally above the top 5 of the nebulizer body 1 at a distance L1.
  • the diameter D1 of this survey can be varied according to an optimal construction, wherein also a diameter D1 is conceivable, which is almost equal to the total diameter of the fog body 1.
  • the support tube 3 is shorter or a pocket 7 in the bottom 8 of the fog body 1 integrated on the bottom 6.
  • the diameter D2 and the height L2 of this pocket 7 should be at least as large as their equivalents L1 and D2 (L2> L2; D2> D1).
  • the diameters D1, D2 are to be chosen such that an interference fit between the two is excluded and that they are adapted to the other components of a projectile 10 (FIG. 3), for example with an ejection plate 13 which is located on the uppermost mist body 1 ,
  • Fig. 3 shows the projectile 10 with several nebulosity 1. All projectile components that determine how long the interior of the projectile 10, in particular the area in which the nebulas 1 are introduced, are provided with predetermined tolerances, so that for the total length the interior 11 is to assume a tolerance of a few millimeters. Therefore, the heights L1 and L2 are to be selected so that in case of unfavorable manufacturing tolerances in case of false building even a single smoke body 1, the bottom 12 of the projectile 10 can not be mounted.

Abstract

L'invention concerne un dispositif pour éviter des erreurs de montage lors de l'assemblage d'un obus (10), notamment d'obus fumigènes, comprenant divers éléments constitutifs ainsi que des corps fumigènes (1), chaque corps fumigène (1) étant conçu de sorte que ses dimensions ne lui permettent d'être monté dans l'obus (10) uniquement dans une position concrète de façon à ce qu'il ne soit pas possible de monter le culot d'obus (12) lorsqu'un corps fumingène voire plusieurs corps fumigènes (1) sont mal engagés dans l'obus (10).
