Definitions

  • the invention relates to a decoy target for an aircraft for repelling infrared-controlled missiles.
  • decoys To ward off infrared-controlled missiles, aircraft are equipped with decoys, so-called flares.
  • the decoys contain effective masses which generate a IR signature disturbing the infrared control of the missiles during burnup.
  • a decoy known for a helicopter From the GB 2 327 116 A is a decoy known for a helicopter.
  • This decoy comprises a housing in which three MTV active materials are provided. The active materials are ignited in succession with a predetermined delay. This can extend the protection period for the helicopter.
  • Infrared controlled missiles with selective discrimination that is in the GB 2 327 116 A disclosed decoy, however, not suitable.
  • the object of the invention is to eliminate the disadvantages of the prior art.
  • a decoy target is to be specified with which infrared-controlled missiles with selective discrimination can be averted with improved effectiveness.
  • a decoy wherein in a cartridge at least two active masses are added, wherein a first active mass produced during burning a blackbody similar spectrum and wherein a second active mass during combustion one of the first active mass different, essentially H 2 O. and CO 2 produced similar spectrum, and wherein an ejection device is provided for time-staggered discharge of the first and second active mass from a cartridge, wherein the ejector is configured such that upon firing first the first active mass and subsequently discharged, the second active mass from the cartridge is, and wherein the second active mass is provided with a braking means for decelerating the falling speed.
  • a plurality of differently acting active compositions are received in a cartridge.
  • different types of infrared-controlled missile can be repelled.
  • the falling speed of the second active mass is decelerated by the braking means.
  • the spectrum produced by the second active mass substantially similar to H 2 O and CO 2 is generated spatially between the blackbody-like spectrum generated by the first active mass and the aircraft. As a result, certain threats can be repelled particularly efficiently.
  • an electric ignition device with pipe protection for igniting.
  • the pipe lock ensures that the active masses only burn off outside the cartridge. This prevents damage to the ejection device or on the aircraft.
  • the braking means is attached to the second active mass parachute or a band.
  • Such braking means are simple, efficient and inexpensive.
  • the braking means is made of a combustible material.
  • Such a brake means burns together with the second active mass.
  • the efficiency of the decoy can be further increased.
  • the first active mass is designed so that it has a shorter burning time than the second active mass. This feature also contributes to improving the defense of infrared-controlled missiles.
  • the hybrid light target comprises a cartridge 1.
  • a first active mass 2, z As an MTV active mass, and a second active mass 3, which generates a H 2 O and CO 2 similar spectrum during combustion.
  • the second active mass 3 is provided with a braking means 4.
  • the braking means 4 is shown schematically here. It can, for. As a parachute or a band.
  • the hybrid light target further comprises an ejector 5.
  • the ejector 5 is formed as an electrically initiatable pulse cartridge for ejecting and igniting the first 2 and the second active mass 3.
  • a pipe lock 6 is provided.
  • the hybrid light target has a cartridge end 7, such as a cover or the like, at an end opposite to the ejector 5.
  • the function of the hybrid light target according to the invention is as follows:
  • the ejector 5 When using the hybrid light target according to the invention, the ejector 5 is triggered electrically. Due to the resulting pressure, the first 2 and the second active mass 3 are moved in the direction of the cartridge end 7. First, the first active mass 2, then the second active mass 3 is ejected from the cartridge 1. By means of the pipe safety device 6, it is ensured in a manner known per se that the active masses 2, 3 do not burn off outside of the aircraft until after the ejection.
  • the second active mass 3 is decelerated by the braking means 4, while the first active mass 2 with a relatively higher speed away from the aircraft.
  • This effect can be further enhanced by the respective shape of the active masses 2, 3.
  • the first active mass 2 with a small surface / volume ratio and the second active mass with a high surface / volume ratio is performed.
  • the first active mass may have the shape of a ball, a cube or a cuboid
  • the second active mass z. B. may be in the form of a flat plate or disc. Because of the different falling speeds of the active masses 2, 3, the substantially H 2 O and CO 2- like spectrum of the second active mass 3 is therefore located between the blackbody-like spectrum of the first active mass 2 and the aircraft.
  • the burning time of the first active mass 2 is shorter than the burning time of the second active mass 3.
  • the braking means 4 is made of a combustible material and burns together with the second active mass 3.
  • the hybrid light target described is particularly suitable for helicopters, but can also be used in other aircraft.
