Definitions

  • the invention relates to an active body or effective masses consisting of a plurality of successively arranged or stacked flares for generating decoupling targets.
  • Such an active body is briefly described for example in DE 199 51 767 C2 and thereby fulfills the object of a dual-mode decoy.
  • the active substance emitting radiation in the IR range is formed here from flares.
  • a camouflage and deception ammunition of this type for the protection of objects against guided missiles containing the active substances forming fog and / or dummy targets is furthermore dealt with in DE 10 2005 020 159 B4.
  • Red phosphorus has been part of military applications for decades, such as nukes for the protection of infantry, artillery and naval vehicles, or aircraft (IR) -effecting aircraft targets.
  • the fog or IR effect unfolds the RP after appropriate ignition by activation by means of burn off.
  • the ignition and distribution of the RP unit takes place in turn classically via an igniting or disintegrating charge, which ensures that the active body or active mass is optimally ignited and distributed for the respective purpose, i. that an optimal blossoming of the IR decoy target to a cloud or a surface area target takes place.
  • Such a new ignition concept is described in more detail in DE 10 2006 004 912 A1. It is a system known to protect, in particular, large flying platforms, such as aircraft, from IR or radar-directed threats.
  • the activation or ignition of the active body preferably takes place without contact. Ejecting the Active body is then performed pneumatically or mechanically.
  • the active bodies themselves are ammunition-free packages which are ignited by means of hot air or a laser.
  • the invention has the object to further develop an active body of the type described in such a way that a reliable mode of action of the active body or its active masses is ensured to form a decoy target.
  • the invention is based on the idea to build up the ammunition-free IR decoy concept on NC (nitrocellulose) and / or RP (red phosphorus) basis and thereby to vary the proportions of NC / RP, wherein the variation between the extrema 0% and 100% can lie.
  • NC nitrocellulose
  • RP red phosphorus
  • the essential parameterization possibilities that are offered by this approach are spontaneity and duration of the IR characteristic, which are reflected in the rising edge and the beam duration, so that the invention enables the parameterization of the beam characteristic of the IR dummy target by the variable components of NC or RP offers.
  • the geometric or spatial distribution can be a desired IR curve of the apparent target between the two extrema (100% NC / 0% RP or 100% RP / 0% NC) even infinitely adjustable.
  • the NC active materials can in turn be brought under ambient pressure (normal atmosphere) to the reaction, they therefore need no additional activation energy.
  • the active compounds are held in shape by a film wrapping or the like.
  • a residue combustible active body shell / active body container now better protection against environmental influences during storage, transport and handling is achieved.
  • This combustible shell is preferably based on NC. The combustibility ensures that no remains of the remains are left over.
  • a kind of ignition transfer layer is incorporated, which serves to optimize the ignition transfer between the active body shell and the active masses.
  • Non-pyrophoric and non-pyrophoric IR decoy target based on NC and / or RP, which can be activated by alternative ignition concepts such. Laser, High temperature, inductive etc.
  • the stacked Einzelflares decay after activation independently.
  • Fig. 1 shows schematically an active body of Einzelflares
  • FIG. 3 shows the active body of Fig. 2 with shell
  • FIG. 4 shows the active body of FIG. 2 with integrated intermediate layer, FIG.
  • Fig. 5 shows the active body of Fig. 3 with predetermined breaking points in the shell.
  • FIG. 1 shows a schematic illustration of an active body 1 consisting of so-called individual flares 10.
  • FIG. 2 shows active masses 5 of an active body marked 1, which is constructed from stacked flares 2, 3.
  • the flares 2, 3 are in this case, for example, or preferably punched NC or RP flare disks, which however do not necessarily have to be circular. Other surface geometries are also possible.
  • the flares 2, 3 are put together in variable proportions. The respective proportions can be varied from 0% to 100%. As a result, the IR beam characteristic of the active body 1 can be controlled.
  • the stacking of the flares 2, 3 can take place alternately, but need not. As a stacking sequence would be a flare 2, then a flare 3 always alternately or two flare 2 and then only a flare 3, etc. (not shown in detail) adjustable.
  • the so-stacked Einzelflarerionn 2, 3 are now introduced into a container or a shell 4.
  • This is preferably made of NC material, for.
  • NC paper NC lacquer, and protects the actual active mass 5 (Einzelflares 2, 3) in particular from environmental influences.
  • the choice of material allows the complete burning of the container 4, which is also lit upon activation of the active body 1.
  • the activation of the active body 1 takes place, for example, laser-based, thermal, etc. with the aid of a so-called ejection tube or the like, such as in one of - A -
  • the active mass can be blackened, which ensures a higher energy input to the active mass by scattering the degree of absorption (eg., Laser absorption). Also possible is an addition of aggregates.
  • an intermediate layer 6 can be incorporated between the container 4 and the active mass 5 (FIG. 3). By this load then control the ignition, for example bescheunigen.
  • the intermediate layer 6 should consist of NC and / or RP granules.
  • Additional predetermined breaking points 7 in the container 4 likewise serve for the optimal decomposition of the active body 1 to form a decoy target after activation / application and serve to optimize the blooming behavior of the decoy target.
  • Such predetermined breaking points are already known by so-called explosive projectiles.

Abstract

L'invention concerne un corps actif (1) comportant plusieurs fusées éclairantes (2, 3) disposées les unes derrière les autres ou empilées, servant de masse active, notamment pour la constitution de cibles fictives, les fusées éclairantes (2, 3) étant des fusées individuelles NC (nitrocellulose) ou RP (phosphore rouge). Les fusées individuelles (2, 3) sont empilées de façon régulière ou irrégulière dans leur séquence de telle manière qu'une fusée individuelle RP (3) vient se loger sur la fusée individuelle NC (2), ou plusieurs fusées individuelles NC (2) ou plusieurs fusées individuelles RP (3) se suivent, les quantités de NC et RP dans le corps actif (1) pouvant varier de 0 à 100 %. Un contenant (4) présentant des zones de rupture (7) reçoit la masse active (5).
