Definitions
- the invention relates to illuminated ammunition with a projectile casing, in which over a target area ejectable bulbs are arranged 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 consists essentially of a slow-burning pyro- technical lighting means (for example, a magnesium compound), which is ejected from the respective ammunition shell after a predetermined period and slides on a parachute to the ground. During its descent, the illuminant emits light in the visible or infrared wavelength range, thereby enabling a battlefield or target illumination as well as a target area reconnaissance.
- a weapon e.g. a mortar, fired (light grenade) or dropped from a missile as a bomb (light bomb). It consists essentially of a slow-burning pyro- technical lighting means (for example, a magnesium compound), which is ejected from the respective ammunition shell after a predetermined period and slides on a parachute to the ground. During its descent, the illuminant emits light in
- the invention has for its object to reveal fluorescent ammunition, which is inexpensive to produce and requires low storage capacity.
- the invention is based essentially on the idea that the respective light emitting tion both first illuminant for brightening the battlefield in the visible wavelength range and second illuminant for brightening the battlefield in the infrared wavelength range, wherein in the interior of the luminous ammunition, for example, operable from the outside switching means for selectively activating one of the two bulbs is provided.
- the lighting means may each consist of a plurality of lighting elements.
- the lighting means are electrical lighting elements which can be connected to an electrical power supply unit via control electronics.
- LEDs Since the luminous elements must be firing-resistant in the event of their use in a grenade, LEDs have proven to be particularly advantageous as luminous elements, with a multiplicity (for example 50-100 LEDs) of an array being used to generate appropriately high intensities for battlefield illumination arranged light-emitting diodes (LEDs) are used.
- halogen lamps or incandescent lamps can serve as a luminous body. If the firing resistance of such lamps when firing grenades from guns is not guaranteed, they can be used as a luminous body in flares, since the luminous bodies are exposed when throwing these bombs from aircraft only relatively low accelerations.
- a thermal battery or a capacitor bank is preferably used as the energy supply unit.
- Such batteries are usually firing resistant and capable of generating high energies within a short time despite a small footprint.
- the light ammunition comprises a parachute, on which the electric lighting elements sink together with the electrical power supply unit and the control electronics during the battle lighting to earth.
- the electronic control system is designed such that it only electrically connects the power supply unit to the respective luminous element when the parachute has already opened.
- the field illumination illuminants as an alternative to the electric illuminants, it may also be pyrotechnic means which illuminate during the burnup in the visible and infrared wavelength ranges.
- the switching device which can be actuated from the outside of the illuminated ammunition is constructed in such a way that either only the ignition element of the first (eg visual) or second (eg infrared) illuminant is activated for battlefield illumination.
- a radially rotatable ammunition part for example, an annular part in the region of the projectile ogive
- adjusting means which by externally passing these means on the light ammunition wirelessly to corresponding optical, electrical or magnetic sensors of the ammunition, and thus the switching device, act.
- the switching device can also be initiated remotely over longer distances and also controlled (switched off, but also dimmed) in the case of electric lighting elements.
- the present solution makes it possible to increase the tactical applications of the ammunition in particular in the context of the function of battlefield lighting.
- the figure shows a trained as a light ammunition artillery projectile.
- the light ammunition designated 1 comprises a projectile casing 2, an ejection charge 3, an ejection plate 4, a projectile fuze 5, a projectile bottom 6 and a lighting unit 7.
- the lighting unit 7 consists essentially of two electric lighting elements 8, 9, each of which may comprise a plurality of light-emitting elements (for example light-emitting diodes), wherein the first light-emitting body 8 for lightening a battlefield in the visible - -
- Wavelength range and the second luminous body 9 is used to brighten the battlefield in the infrared wavelength range.
- the lighting unit 7 includes an electronic switching device 10, a parachute unit 11 and sensors 12 for actuating the electronic switching device 10 from the outside of the illuminated ammunition 1.
- the electronic switching device 10 comprises both a power supply unit 13 and a control electronics 14.
- an electronic special tool for example a chip card
- the control electronics 14 of the switching device 10 is then transferred to the control electronics 14 of the switching device 10 and stored in a corresponding memory of the control electronics 14.
- the ejection charge 3 is initiated with the aid of the projectile fuze 5, and the ejection plate 4 presses the lighting unit 7 out of the projectile casing 2 on the rear side after removal of the projectile bottom 6.
- the parachute 11 opens and the luminous bodies 8, 9 with the switching device 10 slide slowly to the ground.
- the respectively desired luminous element 8 or 9 is also activated on the basis of the stored data.
- the energy supply of the luminous elements of the corresponding luminous element 8 or 9 takes place, for example, by means of a thermal battery.
- control electronics 14 can be switched back and forth between the visual 8 and the infrared 9 light body by means of a certain radio frequency during the lighting phase. Switching off is also possible, for example when the situation requires it.
- pyrotechnic means can also be used as lighting means instead of electric lighting bodies.
