Definitions

  • the invention relates to a thermal insulating layer, in particular, between smoke and flare containers.
  • decoy bodies are used to decoy such guided missiles in order to impede the function of the missiles by jamming, or interference, in order to protect objects.
  • some decoy bodies emit electromagnetic decoy signals (see, e.g., DE 100 16 781 C2), and others form “clouds” of floating dipoles (i.e., chaff clouds), which are matched to the radar frequency of the missile.
  • Pyrotechnic objects are ejected as submunition from a projectile at a specific altitude, and are initiated in the process, before they then fall to the ground as they burn.
  • EP 1 026 473 discloses a method for providing a decoy target for protection of land vehicles, aircraft, or watercraft, or the like, in which the missiles have a target seeker head that operates in the infrared band or radar band, or a target seeker head that operates in both wavelength bands at the same time or successively.
  • the RF active mass in the form of dipole packs in particular, is protected by a heat shield against the blow-out heat.
  • the object of the present invention here is to specify a submunition with active masses that avoids the above-mentioned disadvantages and in which the functional reliability of the active masses is considerably improved.
  • the fourth embodiment is further modified so that preparations or products of non-toxic, organic or inorganic compounds from groups 2, 3 and 4 of the periodic table of the elements, such as magnesium, calcium, boron, aluminum, carbon, silicon and tin, are preferably used.
  • the first embodiment, the second embodiment, the third embodiment, the fourth embodiment, and the fifth embodiment are further modified so that the insulating layer ( 2 ) has a shock-absorbing effect.
  • a submunition having active masses is provided, wherein the submunition includes one or more active mass bodies, wherein each active mass body comprises: (a) an effective agent body container; (b) one or more active masses, wherein each active mass includes a pyrotechnic charge; and (c) an insulating layer disposed between the active body container and the pyrotechnic charge, wherein the active body container is closed by a cover provided with a blow-out opening formed in the cover.
  • the seventh embodiment is modified so that the active mass body is a pyrotechnic smoke body.
  • the seventh embodiment is modified so that the submunition comprises a plurality of active mass bodies, wherein the active mass bodies are smoke bodies.
  • the submunition comprises a plurality of active body containers that are distributed symmetrically around an imaginary projectile longitudinal axis of the submunition.
  • the seventh embodiment is modified so that the insulating layer comprises compounds that are preparations or products of non-toxic, organic or inorganic compounds that include an element selected from the group consisting of magnesium, calcium, boron, aluminum, carbon, silicon and tin.
  • the eleventh embodiment is further modified so that the insulating layer has a shock-absorbing effect.
  • the present invention is based on the idea of including an insulating layer, in particular a thermal insulating layer, between the submunitions to prevent the heat development that results from deliberate combustion of the active masses (i.e., munitions or pyrotechnic devices), and the heat transfer that then follows via the active mass container to active mass layers located underneath.
  • the insulating layer is fitted in/on the active mass container by pushing in, insertion, injection and/or application, after which filling with the pyrotechnic active mass takes place. This ensures that a minimum amount of heat is introduced into the active mass that has not yet been burnt, as a result of the heat transfer during combustion. Flashover and explosive combustion are thus prevented.
  • the separation of the active mass from the container prevents heat from being introduced from the container to the active mass, and/or a reaction from the container on the active mass, during combustion.
  • this layer has a shock-absorbing effect and is, therefore, suitable for minimizing the force/impulse introduced to the active mass as a result of striking the ground.
  • the insulating layer prevents the active mass from falling out of place as a result of strength losses, in particular, resulting from heat development.
  • Preparations or products of non-toxic, organic or inorganic compounds from groups 2, 3 and 4 of the periodic table of the elements, such as magnesium, calcium, boron, aluminum, carbon, silicon and ting are preferably used in accordance with the present invention.
  • compounds whose chemical and physical characteristics comply with the characteristic preconditions of an insulating layer are used as the basis for forming the insulating layer.
  • an insulating layer therefore, in accordance with the present invention improves the functional reliability by initiation of uniform combustion of the active mass until completion of burning, and, associated with this, improves a more uniform function by the active bodies. Furthermore, the inclusion of the insulating layer also improves safety with regard to objects thrown out during explosive combustion.
  • FIG. 1 which shows an active mass body for a submunitions having one or more active masses in accordance with the present invention
  • FIG. 2 which shows schematically a submunitions incorporating the active mass body of FIG. 1 .
  • FIG. 1 shows the basic design of a pyrotechnic smoke body 1 (i.e., an active mass body, or more simply an “active body”) having an insulating layer 2 disposed between the active body container 3 and the pyrotechnic charge 4 (i.e., an active mass).
  • the active body container 3 contains a plurality of active masses 4
  • the pyrotechnic smoke body 1 may contain a plurality of active body containers 3 , with each containing an active mass 4 .
  • the active body containers 3 are distributed symmetrically around an imaginary projectile longitudinal axis 10 .
  • a plurality of active body containers 3 can thus form a submunition to be fired (not illustrated in any more detail).
  • the container 3 or the housing can be closed by a cover 5 with a blow-out opening 6 .
  • a submunitions 100 is constructed that incorporates one or more active mass bodies 1 .
