Definitions

  • the invention relates to a so-called active body, consisting of juxtaposed or successively arranged Einzelflares, in particular the optimization of Flareusionnseparation means of a hydrophobic separation layer.
  • 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.
  • IR-acting RP flares are currently produced by applying red phosphorus in conjunction with a binder to a carrier film (substrate). This material is punched into the desired shape. - -
  • the invention has the object to show an active body, by means of which the disadvantages known from practice prevented and an optimal flowering not only the active body can be realized with a disintegration charge.
  • the adhesion or sticking of Einzelflares should be prevented, which is caused by adhesion or residual and ambient moisture.
  • the invention is based on the idea to bind the flares instantaneously (quickly, without delay) and sustainably with minimal throughput times and operating costs in the production process.
  • This is realized by incorporating a hydrophobic material.
  • a hydrophobic layer preferably powder / powder - such as glass microspheres - the adhesion is as well as the adhesion between the Einzelflares prevented.
  • the inhibition of the adhesion is permanent, whereby by the hydrophobic nature of the (preferably powdery) material - which serves as a release layer - is guaranteed even at elevated ambient humidity sticking.
  • hydrophobic separation layer is preferably effected by a powder consisting, for example, of microspheres, etc., which is applied to the flares at least on one side or the like.
  • the application of the powder or powder is manufacturing technology on the unpunched Flarebahnen or for example by mixing powder and flares in a mixing drum possible.
  • Alternatives are known to the person skilled in the art.
  • separating disk between the flares as a separating layer, which additionally has anti-cohesive and anti-adhesive properties.
  • Such a structure of the active body has, inter alia, the advantage that can be dispensed with long time and temperature-controlled process (heating - drying).
  • the storage of the body can be simplified. Due to the improved performance of the IR decoy target, it is also possible to save RP effective mass.
  • NC flares nitrocellulose flares
  • Fig. 2 shows another active body of Einzelflares with separate separation layer.
  • An active body 1 shown schematically in FIG. 1 as well as in FIG. 2 consists of a plurality of flares 2 (FIG. 1) which are already stamped here. Between the flares 2 (eg NC base and / or RP base), only a hint of a powder layer 3 is shown in FIG. 1, which is preferably applied over the entire surface 4 of the respective lower or upper flare 2.
  • the layer 3 serves as a separating layer between the flares 2 and can be applied to the unpunched flake webs or be created by mixing powder / powder and stamped flares 2, for example in a mixing drum.
  • a separate separating layer 5 between the actual active mass (flaring disks 6, 7) shows the other variant in FIG. 2.
  • the release layer 5 can be realized by a hydrophobic, anti-cohesive and anti-adhesive coated paper. These are stacked between the discs 6, 7 in the sequence Flaremount 6, cutting disc 5, Flarefactor 7, separating layer 5, etc. As a result, Flareusionn 6, 7 on RP or NC basis but also be RP and NC basis. The Flareframen 6, 7 need not be round.
  • the layer structure itself can be designed individually, d. h., alternating evenly or unevenly, in order or as a mix.
  • the discs can also be formed here from NC and RP.

Abstract

L'invention concerne un corps actif (1) comportant des fusées éclairantes (2, 6, 7) juxtaposées, superposées ou disposées les unes derrière les autres. Selon l'invention, au moins une couche de séparation hydrophobe (3, 5) est disposée entre les fusées éclairantes ou les disques de fusées éclairantes (2, 6, 7) afin d'empêcher une adhérence ou un collage des fusées éclairantes (2, 6, 7). Dans un mode de réalisation, la couche de séparation hydrophobe (3) est appliquée, au moins de manière unilatérale ou similaire, de préférence sous forme de poudre, de préférence composée de microbilles, sur les fusées éclairantes (2). Dans un autre mode de réalisation, un disque de séparation servant de couche de séparation (5), présentant par ailleurs des propriétés anti-cohésion ou anti-adhérence, est disposé entre les fusées éclairantes (6, 7).
