Definitions

  • the invention is concerned with a mechanically adjustable delay element in an ammunition, fired in particular by a mortar, a launcher or hand held weapons. This delay time is set in the delay element by hand and then inserted into the ammunition, for example screwed. This can be programmed individually and quickly on site depending on the use of ammunition this mechanically.
  • the ranges of mortar shells, missile projectiles with directional elevation angles or hand-held launchers, as with other weapon systems, are determined by the strength of the propellant charge and the elevation of the pipe set.
  • Warheads may be provided with an impact fuze when initiated by impact. However, if the effect unfolds earlier than the impact, proximity sensors can also be integrated. Alternatively, such projectiles may for example be given an ignition or delay time, or the ignition time may be impressed after a measurement, etc.
  • Such projectiles are expensive due to the electronics, the sensor technology as well as the software in the production.
  • DE 36 39 201 C2 discloses a friction device for the Tempiervorgang on Geunterzeitzündern.
  • the projectile-fuze consists essentially of an upper detonator tip, which is screwed on, a rotatable GeHousemititteitei! and a fixed housing base.
  • the middle part of the housing is designed as a Tempierring. By turning the Tempierrings the detonator is tempiert.
  • DE 34 34 100 A1 relates to a projectile fuse in which the transit time is adjusted mechanically by corresponding rotation of a projectile nose. From DE 23 52 967 C3 an arrangement for adjusting the Zündverzugszeit is known. The Tempierusion the igniter is coupled to an actuator (stepper motor). After pressing the start button and reaching the preselected number of steps of the actuator, a Zündimpuis is delivered to the propellant charge of the projectile.
  • DE 977 759 B is concerned with a clock with a revolving timing ring.
  • the invention has as its object to show a more cost-effective ammunition especially for hand held (hand-fired ammunition) or directional throwers.

  • the idea aims that a simple adjustment of the delay time, for example, with slight twisting of two parts to each other is possible.
  • a simple guide scale is used as the measuring or reading device.
  • Core of the invention is a retardation element with a tube which has a thread or the like over a part of its length and the remaining part is smooth.

  • the pipe itself has a through hole into which a chemical mixture is pressed in as a delay set.
  • a sleeve is mounted over the tube, which fits snugly over the cylindrical part of the tube at one end and at the other end has the matching thread of the tube.
  • the simple setting of the delay time on site also allows a broad range of applications for the same ammunition for different application scenarios.
  • an ammunition with low susceptibility to interference is realized.
  • An ammunition or an active body is created with increased accuracy by changing the delay time of the delay element, comparable to a time fuse.
  • an already set delay time can be reset at any time.

  • Fig. 1 and Fig. 2 show a delay element 10, consisting of a tube 1, a sleeve 2 and a chemical set 3 as a delay set.
  • the tube 1 has on one side a thread a and on the other side a cylindrical, preferably smooth surface b.
  • On the tube cylinder b is a slot c.

  • the delay element 10 is integrated, for example, in a designated 1 assembly, which can be incorporated into an ammunition or the like in a known manner.

  • Advantage of this design is that fewer revolutions of both parts 7, 8 are necessary because the gear ratio helps. Further halving is possible by using a double thread a.

Abstract

L'invention concerne un ajustement de retard mécanique variable simple. L'objectif de l'invention est d'obtenir un ajustement simple de la durée de retard, par exemple par une légère mise en rotation de deux parties d'ensemble (7, 8) dans lesquelles est intégré l'élément retardateur ajustable (10). L'invention est caractérisée en ce que l'élément retardateur (10) est constitué d'un petit conduit (1) présentant, sur une partie de sa longueur, un filet (a) ou analogue, et étant lisse sur la partie restante (b). Dans cette partie cylindrique lisse du conduit (1) se trouve une fente mince. Dans le conduit (1) se trouve un trou traversant dans lequel est comprimé un mélange chimique servant de composition retardatrice (3). Sur le conduit (1) est montée une douille (2) qui s'ajuste avec précision à une extrémité, sur la partie cylindrique (b) du conduit (1), et comporte, à l'autre extrémité, le filet correspondant du conduit (1). La rotation des deux parties d'ensemble (7, 8) permet d'agrandir ou de réduire (raccourcir) la fente (c) contenant la composition retardatrice (3). Ainsi, une fois la composition retardatrice (3) allumée, la durée de combustion est modifiée. Cette durée de combustion peut ainsi être ajustée en continu.
