  • Known IR active bodies consist of a particular cylindrical body which is formed by stacking individual active body leaves (flare leaflets or discs). The resulting package is held together by a foil or other compound, such as plastic cord, etc.
  • the film itself serves to protect the active body against environmental influences and storage, transport and in the dispenser itself.
  • a new ignition concept in particular for the formation of decoy clouds in civil aviation, etc. without ignition and explosives 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 ignition speed can be increased by additionally introducing a suitable ignition aid / mixture inside the shell.
  • the ignition can take place on the one hand over the surface of the active body or by a centrally located ignition along the longitudinal axis.
  • the spectral properties of the combustible shell can be optimized by incorporating materials to alter the reflection / absorption properties. In particular, the coupling of laser radiation can thus be improved and the ignition speed can be increased.

Abstract

L'invention ne prévoit pas d'entourer un corps actif (1) d'un film ou similaire, mais de l'encapsuler de telle sorte que l'encapsulage ou l'enveloppe (2) favorise le comportement à l'allumage de la masse active ou des composants (3, 4). Le nouveau corps actif (1) se caractérise donc par une enveloppe (2) pour le logement des composants (3, 4) du corps actif (1), qui sont différents en ce qui concerne la composition chimique et ses propriétés. Dans l'enveloppe (2) se trouve un composant supplémentaire (5) comme aide d'amorçage. L'amorçage du corps actif (1) peut se faire d'une part par la surface supérieure/surface latérale (10) du manchon (2) ou également par un mélange d'allumage intérieur (6) se trouvant à l'intérieur du corps actif (1).
