Definitions

  • the invention relates to illuminated ammunition for battlefield lighting.
  • Flare ammunition for battlefield illumination is either made of a weapon, e.g. a mortar, fired (light grenade) or dropped from a missile as a bomb (light bomb). It essentially consists of a slow-burning pyro- technical flare (for example, a magnesium compound), which is ejected from the respective ammunition sheath after a predetermined period of time and slides on a parachute to the earth.
  • the flare emits light in the visible and / or infrared wavelength range during its descent, thereby enabling target illumination or target area reconnaissance.
  • a disadvantage of using known light ammunition is, inter alia, that the pyro-technical flare regularly represents a risk because it can ignite unintentionally and explode.
  • the pyro-technical flare regularly represents a risk because it can ignite unintentionally and explode.
  • when burning in descending burning parts can solve and fall to the ground, which is associated with an increased risk of fire and a risk to people and the environment as well as a shortening of the burning time.
  • the flare is designed for infrared lighting of the battlefield, visible light is inevitably emitted by the burn, which should be avoided in itself.
  • the expense associated with evacuating and recovering pyrotechnic material is relatively large.
  • the invention has for its object to reveal fluorescent ammunition, which does not have the disadvantages of the known light ammunition with pyrotechnic flares. In particular, therefore, the risk of unintentional burning of the flare should be safely avoided and carried out a safe simple subsequent eviction and recovery of the corresponding filament.
  • the invention is based essentially on the idea not to use a pyrotechnic flare for the light ammunition, but an electric filament that emits light in the visible and / or infrared wavelength range and which is connected to an energy source for the luminous body supplying energy.
  • the light ammunition according to the invention comprises an electrical or electronic control device, which establishes the connection of the electric filament to the energy source during descent
  • the electric lamps can generate light with a clearly defined wavelength range, so that infrared illumination without unwanted light in the visible range is possible.
  • LEDs light-emitting diodes
  • a multiplicity for example 50-100 LEDs
  • LEDs light-emitting diodes arranged in the form of arrays for generating correspondingly high intensities for battlefield illumination (LEDs) are used.
  • halogen lamps, incandescent lamps or gas discharge lamps can also serve as a luminous element. If the firing resistance of such electric bulbs is not guaranteed when firing grenades from guns, they can be used as a luminous body in flares, since the luminous bodies are exposed to relatively low accelerations when dropping these bombs from aircraft.
  • a thermal battery or a capacitor bank is preferably used as the energy source.
  • Such batteries are usually firing resistant and able to withstand a short space of time despite a small footprint. to provide energy.
  • the figure shows schematically a ejected from a projectile shell and hanging on a parachute 1 luminous body 2 during its descent.
  • the luminous element 2 consists essentially of a cylindrical housing 3 and a base plate arranged on the housing 3 support plate with a plurality of array-like arranged light emitting diodes (LEDs) 4, which illuminate a battlefield 5.
  • LEDs array-like arranged light emitting diodes
  • the LEDs 4 of the filament 2 are connected via an electronic control device 6 with a thermal battery 7.
  • the control device 6 ensures that the power supply of the LEDs 4 takes place only after opening the parachute 1 and only during the subsequent sinking phase of the filament 2.
  • the battery 7, the electronic control device 6 and the luminous element 2 can also be accommodated in a common housing, which is closed on the bottom side or by a light-permeable protective wall. At this common housing can then be provided a receptacle on which the parachute 1 is articulated.
  • a battery instead of a thermal battery, for example, a capacitor bank or other known storage media for electrical energy can be used.

Abstract

L'invention concerne un projectile éclairant qui peut être tiré à partir d'une arme ou éjecté d'un missile. L'invention vise à empêcher de manière fiable une inflammation involontaire de la composition éclairante et le risque d'explosion qui en résulte, et à permettre une récupération ultérieure simple et sans danger du corps de l'élément lumineux correspondant. A cet effet, selon l'invention, on n'utilise pas pour le projectile éclairant de composition éclairante pyrotechnique, mais un élément lumineux électrique (2) qui, en fonction de l'utilisation prévue, émet de la lumière dans la plage visible et/ou dans la plage infrarouge.
