Definitions
- the invention relates to an ammunition or a projectile or the like with several lights 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 slowly burning pyrotechnic flare (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. The flare emits light in the visible and / or infrared wavelength range during its descent, thereby enabling target illumination or target area reconnaissance.
- a weapon e.g. a mortar, fired (light grenade) or dropped from a missile as a bomb (light bomb).
- pyrotechnic flare for example, a magnesium compound
- luminous projectiles include a single luminous element. This is ejected from the projectile casing by a discharge charge after a time adjustable at Zeitzünder. Alternatively, when artillery projectiles are ejected, the soil is separated and the submunition is forced out of the projectile shell via a discharge plate. The luminous element is then braked by one or more parachute systems.
- a projectile with a payload describes the DE 28 30 224 C2 ,
- the carried payload is a light body with a parachute as a braking system.
- a light pot for projectiles, etc. reveals the DE 75 11 529 U1 , This is ejected during flight while igniting the flare from the projectile casing, the flame jet of the parachute floating to the ground luminescent pot exits down from this.
- the US 3,491,689 A1 relates to a projectile with a payload to be released at a certain point in the trajectory, such as a beacon charge.
- This payload is provided with a parachute which opens at the moment of separation and, due to the payload effect it causes, allows a moderate speed descent.
- the projectile casing in addition to the Ausschladung for the payload contains a drive charge and has a lateral nozzle, which is arranged behind the center of gravity of the projectile. Under the effect of the emission of gaseous products of combustion, this driving charge generates a stall torque on the projectile, with delays between the igniter and the ejection and drive charge built-in. This delay is such that the burnup of the drive charge precedes the ignition of the ejection charge. As a result, the parachute unfolds outside the trajectory of the projectile body.
- a bomblet carrier bullet having training bullets disposed in a projectile shell is known that is ejected over a target area from a pusher unit.
- the casings of the exercise bomblets are light, buoyant and will not develop any dangerous splinters when the charge detonates.
- the housings within the Bombletskygeunteres are supported in layers, including in the Sugeunterhülle in storey-axial direction stackable support elements are arranged as a radial support discs and for distancing these support discs space-saving Axial gan.
- the luminous element consists essentially of a cylindrical housing and a base plate arranged on the housing carrier plate with a plurality of array-like arranged light emitting diodes (LEDs) that illuminate a battlefield and hang on a parachute.
- the LEDs of the filament are via an electronic control device connected to a power source. In this case, the control device ensures that the power supply of the LEDs takes place only after opening the parachute and only during the subsequent sinking phase of the filament.
- the disadvantage is that in a malfunction of the parachute, the battlefield is not lit at all. In weather-related situations, such as gusty wind, there may be lurching or tumbling movements. These cause shadow movements due to the moving filament and make it difficult to observe the battlefield. The actual function of the filament is then given only conditionally.
- the diameter of the filament is also relatively large. This makes them very heavy and cause a large dimensioning of the parachute. In the case of floor separation, damage to the parachute system may occur.
- a multiple charge for lighting a ground surface or a body of water is known.
- a predetermined number of partial charges, each with a pyrotechnic flare and associated parachute is integrated in a cavity of a body or container.
- Each partial load is provided with a delay powder charge adapted to each partial load involved.
- the different partial charges have different delay times, and indeed the partial charge which is pushed out of the container before another has the shorter delay time. This will achieved that a successive driving out of the partial charges from the body or the container takes place in the atmosphere, while the delay times themselves are chosen so that there is a wide scattering of the partial charges in the atmosphere.
- the invention has the object to show a luminous ammunition with multiple charge, which no longer has the aforementioned disadvantages.
- the invention is based on the idea also to place a plurality of luminous bodies in a projectile or a projectile casing, wherein the fall speed reduction systems or braking systems (such as parachute etc.) is made ready for operation only after a predetermined time of flight and stabilization and by a delay element.
- the delay time of the ignition of the individual luminous elements should be selectable differently.
- the luminous bodies can be introduced into all types of containers or casings, such as artillery shell casings. Patches between the luminaries are to be adapted to this, if necessary, the number of luminous elements.
- the filling pieces or filling elements preferably form a firing channel in the center for the ignition of the filament.
- the luminous bodies Due to the eccentric mounting of the luminous bodies within the projectile shells, the luminous bodies are distributed more expensively after the ejection than the known illuminant or multiple illuminator. This also means that the luminous bodies can be hit or damaged less by the floor of the basement.
- the shape of the filaments makes it possible to act as modules for different projectiles. Due to the distribution of several luminaires in several levels in the floor, a better illumination is achieved by the luminous bodies illuminating at the same time.
- the luminous elements are integrated in two or more levels within the projectile and the delay times of the luminous elements of the levels will differ. Due to the different adjustable delay times, the luminous bodies then start to light up at different times. The advantage associated with this is that if the different delays are tuned, the total illumination time can be extended. In case of a malfunction of a fall speed reduction system or the ignition, the other lamps remain functional in turn.
- non-spin stabilized bullets are also possible.
- the filaments are accelerated by the ejection charge via the Anzündkanal radially away from the projectile casing.
- Another advantage is that with these luminaires with sufficient illumination, an unwanted dazzling can be avoided.
- a projectile 1 is shown, which is composed of a projectile casing 2, a discharge charge 3 and a discharge plate.
- a projectile fuze 5 and a floor 6 are located in the floor 1 of the further luminous body 7 and filling elements 8.
- the filament 7 are here in two levels 14, 15 introduced.
- eight luminous bodies 7 are integrated in the projectile 1.
- the filling elements 8 preferably form centrally in the projectile 1 a channel 10 for the discharge gases via the delay elements 11, 12 of the filament 7 are lit.
- the individual luminous element 7 itself consists of a casing 18, in which, for example, a pyrotechnic flare 19, and in this case preferably two delay elements 11, 12 or a two-stage delay element, an ejection system 16, 22 and a parachute 17 are accommodated ( Fig. 2 ).
- a stabilizing element 13 On the outer shell is a stabilizing element 13, but this is not absolutely necessary.
- the time is set, after which the initiation of the ejection charge 3 should take place.
- the range is determined in which the battlefield lighting is to take place.
- the projectile fuze 5 initiates the ejection charge 3.
- a pressure is generated in the projectile envelope 2 in the area of the projectile 9, which acts on the ejection plate 4 and on the illuminant 7 and the filling elements 8 on the floor of the projectile 6 is transmitted.
- the bottom 6 shears off and the filament 7 as well as the filling elements 8 are ejected through the ejection plate from the projectile casing 2 to the rear.
- the combustion gases are passed via the channel 10 to the delay elements 11, 12 of the luminous element 7.
- the transmission from the channel 10 to the delay elements 11, 12 takes place via ignition bores 23 in the filling elements 8.
- the luminous bodies 7 After the emission of the luminous bodies 7 from the projectile casing 2, the luminous bodies 7 are distributed, for example due to the projectile spin. In this case, the swirl and the speed are reduced by stabilizing elements 13 to the filament 7 and ensures a defined case.
- the stabilizing elements 13 on the luminous bodies 7 can be spread by the eigendrall of the luminous bodies 7. Other possibilities are also given.
- a separating screw 16 or the like is separated and a cover 22 repelled.
- the parachute 17 can now unfold at the respective luminous element 7.
- the actual pyrotechnic flares 19 are ignited.
- the durations of the second delay elements 12 differ in the luminous bodies 7 of the levels 14, 15.
- the light sets 7 of level 14 or 15 begin to burn down and illuminate the battlefield 20. Due to the scattering 21 of the luminous element 7 after ejection from the projectile casing 2, the illuminated battlefield 20 is larger than the area illuminated by a single luminous element 7.
- the delay elements 12 of the luminous elements 7 of the different levels 14, 15 are matched to one another such that the Light sets 19 of the level 14, 15 are ignited before the luminous bodies 7 of the other level start to shine. This delay can increase the total illumination time compared to conventional lighting systems.
- LEDs can be used instead of the pyrotechnic flare 19.
- LEDs can be used instead of the pyrotechnic flare 19.
- a double-stage delay means (11, 12) in the form described, since a simple is sufficient.

Description
Die Erfindung betrifft eine Munition oder ein Geschoss oder dergleichen mit mehreren Leuchtkörpern zur Gefechtsfeldbeleuchtung.The invention relates to an ammunition or a projectile or the like with several lights for battlefield lighting.
Leuchtmunition zur Gefechtsfeldbeleuchtung wird entweder aus einer Waffe, z.B. einem Mörser, verschossen (Leuchtgranate) oder aus einem Flugkörper als Bombe abgeworfen (Leuchtbombe). Sie besteht im Wesentlichen aus einem langsam abbrennenden pyrotechnischen Leuchtsatz (beispielsweise eine Magnesiumverbindung), der aus der jeweiligen Munitionshülle nach einer vorgegebenen Laufzeit ausgestoßen wird und an einem Fallschirm zur Erde gleitet. Der Leuchtsatz emittiert während seines Sinkfluges Licht im sichtbaren und/oder infraroten Wellenlängenbereich und ermöglicht dadurch eine Zielbeleuchtung oder Zielgebietsaufklärung.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 slowly burning pyrotechnic flare (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. The flare emits light in the visible and / or infrared wavelength range during its descent, thereby enabling target illumination or target area reconnaissance.
Bekanntlich beinhalten Leuchtgeschosse einen einzigen Leuchtkörper. Dieser wird durch eine Ausstoßladung nach einer, am Zeitzünder einstellbaren Zeit, aus der Geschosshülle ausgestoßen. Alternativ wird bei Artilleriegeschossen beim Ausstoß der Boden abgetrennt und die Submunition über eine Ausstoßplatte aus der Geschosshülle herausgedrückt. Der Leuchtkörper wird dann durch ein oder mehrere Fallschirmsysteme gebremst.As is known, luminous projectiles include a single luminous element. This is ejected from the projectile casing by a discharge charge after a time adjustable at Zeitzünder. Alternatively, when artillery projectiles are ejected, the soil is separated and the submunition is forced out of the projectile shell via a discharge plate. The luminous element is then braked by one or more parachute systems.

Handelt es sich zudem um einen Leuchtkörper mit pyrotechnischer Zündung, hat dies den Nachteil, dass der pyrotechnische Leuchtsatz regelmäßig ein Risiko darstellt, weil er sich unbeabsichtigt entzünden und explodieren kann. Außerdem können sich beim Abbrand im Sinkflug brennende Teile lösen und auf die Erde fallen, was mit einer erhöhten Brandgefahr und einer Gefährdung von Personen und Umwelt sowie mit einer Verkürzung der Brenndauer verbunden ist. Sofern der Leuchtsatz für eine Infrarot-Beleuchtung des Gefechtsfeldes ausgelegt ist, wird durch den Abbrand zwangsläufig auch sichtbares Licht emittiert, was an sich gerade vermieden werden sollte. Schließlich ist der mit der Räumung und Bergung von pyrotechnischem Material verbundene Aufwand relativ groß.If it is also a luminous body with pyrotechnic ignition, this has the disadvantage that the pyrotechnic flare regularly represents a risk because he is accidentally ignite and explode. In addition, 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. If the flare is designed for infrared lighting of the battlefield, visible light is inevitably emitted by the burn, which should be avoided in itself. Finally, the expense associated with evacuating and recovering pyrotechnic material is relatively large.

Nachteilig ist, dass bei einer Fehlfunktion des Fallschirms das Gefechtsfeld überhaupt nicht beleuchtet wird. In wetterbedingten Situationen, beispielsweise böigem Wind, kann es zu Schlinger- oder Taumelbewegungen kommen. Diese bewirken Schattenbewegungen aufgrund des sich bewegenden Leuchtkörpers und erschwert die Beobachtung des Gefechtsfelds. Die eigentliche Funktion des Leuchtkörpers ist dann nur noch bedingt gegeben.The disadvantage is that in a malfunction of the parachute, the battlefield is not lit at all. In weather-related situations, such as gusty wind, there may be lurching or tumbling movements. These cause shadow movements due to the moving filament and make it difficult to observe the battlefield. The actual function of the filament is then given only conditionally.
Bei Artilleriegeschossen ist der Durchmesser des Leuchtkörpers zudem verhältnismäßig groß. Dadurch sind sie auch sehr schwer und bewirken eine große Dimensionierung des Fallschirmes. Im Falle der Geschossbodentrennung kann es beim Öffnen des Fallschirmsystems zu Beschädigungen an diesem kommen.In artillery projectiles, the diameter of the filament is also relatively large. This makes them very heavy and cause a large dimensioning of the parachute. In the case of floor separation, damage to the parachute system may occur.

Hiervon ausgehend stellt sich die Erfindung die Aufgabe, eine Leuchtmunition mit Vielfachladung aufzuzeigen, welche die vorgenannten Nachteile nicht mehr aufweist.On this basis, the invention has the object to show a luminous ammunition with multiple charge, which no longer has the aforementioned disadvantages.
Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausführungen sind in den Unteransprüchen angedacht.The object is achieved by the features of
Der Erfindung liegt die Idee zugrunde, ebenfalls mehrere Leuchtkörper in ein Geschoss bzw. eine Geschosshülle zu platzieren, wobei die Fallgeschwindigkeitsreduzierungssysteme bzw. Bremssysteme (wie Fallschirm etc.) erst nach einer vorbestimmten Flugzeit und einer Stabilisierung und durch ein Verzögerungselement funktionsbereit gemacht wird. Die Verzögerungszeit der Anzündung der einzelnen Leuchtkörper sollte dabei unterschiedlich wählbar sein. Die Leuchtkörper können in alle Arten von Behältern oder Hüllen, wie Artilleriegeschosshüllen, eingebracht werden. Füllstücke zwischen den Leuchtkörpern sind an diese anzupassen, gegebenenfalls auch die Anzahl der Leuchtkörper. Die Füllstücke bzw. Füllelemente bilden vorzugsweise mittig einen Anzündkanal für die Zündung der Leuchtkörper. Aufgrund der exzentrischen Lagerung der Leuchtkörper innerhalb der Geschosshüllen verteilen sich die Leuchtkörper nach dem Ausstoß weit günstiger als der bekannte Einleuchtkörper oder Vielfachbeleuchter. Dies hat des Weiteren zur Folge, dass die Leuchtkörper vom Geschossboden weniger getroffen bzw. beschädigt werden können.The invention is based on the idea also to place a plurality of luminous bodies in a projectile or a projectile casing, wherein the fall speed reduction systems or braking systems (such as parachute etc.) is made ready for operation only after a predetermined time of flight and stabilization and by a delay element. The delay time of the ignition of the individual luminous elements should be selectable differently. The luminous bodies can be introduced into all types of containers or casings, such as artillery shell casings. Patches between the luminaries are to be adapted to this, if necessary, the number of luminous elements. The filling pieces or filling elements preferably form a firing channel in the center for the ignition of the filament. Due to the eccentric mounting of the luminous bodies within the projectile shells, the luminous bodies are distributed more expensively after the ejection than the known illuminant or multiple illuminator. This also means that the luminous bodies can be hit or damaged less by the floor of the basement.
Die Form der Leuchtkörper ermöglicht es zu dem als Module für verschiedene Geschosse zu fungieren. Durch die Verteilung von mehreren Leuchtkörpern in mehreren Ebenen im Geschoss wird eine bessere Ausleuchtung durch die zeitgleich leuchtenden Leuchtkörper erreicht.The shape of the filaments makes it possible to act as modules for different projectiles. Due to the distribution of several luminaires in several levels in the floor, a better illumination is achieved by the luminous bodies illuminating at the same time.
Die Leuchtkörper sind in zwei oder mehreren Ebenen innerhalb des Geschosses integriert und die Verzögerungszeiten der Leuchtkörper der Ebenen werden unterscheiden. Aufgrund der unterschiedlich einstellbaren Verzögerungszeiten beginnen die Leuchtkörper dann zu unterschiedlichen Zeiten zu leuchten. Der sich damit verbindende Vorteil liegt darin, dass bei Abstimmung der unterschiedlichen Verzögerungen die Gesamtbeleuchtungsdauer verlängert werden kann. Bei Fehlfunktion eines Fallgeschwindigkeitsreduzierungssystems oder der Anzündung bleiben die anderen Leuchtkörper ihrerseits funktionsfähig.The luminous elements are integrated in two or more levels within the projectile and the delay times of the luminous elements of the levels will differ. Due to the different adjustable delay times, the luminous bodies then start to light up at different times. The advantage associated with this is that if the different delays are tuned, the total illumination time can be extended. In case of a malfunction of a fall speed reduction system or the ignition, the other lamps remain functional in turn.
Die Integration mehrerer Leuchtkörper hat des Weiteren den Vorteil, dass aufgrund der geringeren Masse und Größe die Geschwindigkeitsreduzierungssysteme nicht mehr so stark belastet werden. Es können einfachere Stabilisierungsmechanismen eingebunden werden, die ihrerseits die Drall- und Geschwindigkeitsbelastungen stark reduzieren, wodurch einfache Fallsysteme verwendet werden können. Eine mit der Gewichtsreduzierung verbundene wettertechnische Abhängigkeit wird dadurch aufgehoben, dass bei starken Böen die damit verbundenen Taumelbewegungen durch alle Leuchtkörper ausgeführt werden - der zu beleuchtende Boden aus mehreren Richtungen selbst beim Taumeln ausgeleuchtet wird.The integration of several luminous bodies also has the advantage that due to the smaller mass and size, the speed reduction systems are no longer so heavily loaded. Easier stabilization mechanisms can be incorporated, which in turn greatly reduce spin and velocity loads, allowing for simple fall systems to be used. A related with the weight reduction technical dependence is offset by the fact that in strong gusts the associated tumbling movements are performed by all the luminous body - the illuminated floor is illuminated from several directions even when tumbling.
Die Nutzung von nicht Drall stabilisierten Geschossen ist gleichfalls möglich. Hier werden die Leuchtkörper durch die Ausstoßladung über den Anzündkanal radial von der Geschosshülle weg beschleunigt.The use of non-spin stabilized bullets is also possible. Here, the filaments are accelerated by the ejection charge via the Anzündkanal radially away from the projectile casing.
Prinzipiell wird durch die Einbindung eines Anzündkanals ermöglicht, dass nur eine Zündeinrichtung für die mehreren Leuchtkörpern benötigt wird.In principle, the integration of an ignition channel makes it possible for only one ignition device to be required for the plurality of luminous bodies.
Ein weiterer Vorteil liegt darin, dass mit diesen Leuchtkörpern bei einer ausreichenden Ausleuchtung ein ungewolltes Blenden vermieden werden kann.Another advantage is that with these luminaires with sufficient illumination, an unwanted dazzling can be avoided.

Der einzelne Leuchtkörper 7 selbst besteht aus einer Hülle 18, in welche beispielsweise ein pyrotechnischer Leuchtsatz 19, und in diesem Fall dann vorzugsweise zwei Verzögerungselemente 11, 12 oder ein zweistufiges Verzögerungselement, ein Ausstoßsystem 16, 22 sowie ein Fallschirm 17 untergebracht sind (
Über den Geschosszünder 5 wird die Zeit eingestellt, nach welcher die Initiierung der Ausstoßladung 3 erfolgen soll. Über die Höhenrichtung der Waffe (nicht näher dargestellt), der Auswahl der Ladung und Einstellung des Geschosszünders 5 wird die Reichweite bestimmt, in der die Gefechtsfeldbeleuchtung erfolgen soll.About the
Nach Ablauf der Zünderlaufzeit initiiert der Geschosszünder 5 die Ausstoßladung 3. Durch den Abbrand der Ausstoßladung 3 wird in der Geschosshülle 2 im Bereich der Geschossogive 9 ein Druck erzeugt, der auf die Ausstoßplatte 4 wirkt und über die Leuchtkörper 7 und die Füllelemente 8 auf den Geschossboden 6 übertragen wird. Mit Erreichen des notwendigen Druckes schert der Boden 6 ab und die Leuchtkörper 7 wie auch die Füllelemente 8 werden durch die Ausstoßplatte aus der Geschosshülle 2 nach hinten ausgestoßen. In etwa gleichzeitig, während sich der Druck in der Geschossogive 9 aufbaut, werden die Verbrennungsgase über den Kanal 10 zu den Verzögerungselementen 11, 12 der Leuchtkörper 7 geleitet. Die Übertragung vom Kanal 10 zu den Verzögerungselementen 11, 12 erfolgt über Anzündbohrungen 23 in den Füllelementen 8.After expiration of the detonator running time, the
Nach dem Ausstoß der Leuchtkörper 7 aus der Geschosshülle 2 verteilen sich die Leuchtkörper 7 beispielsweise aufgrund des Geschossdralls. In diesem Fall werden durch Stabilisierungselemente 13 an den Leuchtkörpers 7 der Drall als auch die Geschwindigkeit reduziert und ein definierter Fall gewährleistet. Die Stabilisierungselemente 13 an den Leuchtkörpern 7 können durch den Eigendrall der Leuchtkörper 7 ausgebreitet werden. Andere Möglichkeiten sind auch gegeben.After the emission of the
Nach Ablauf der Verzögerungszeit, die beispielsweise durch das erste Verzögerungselement 11 einstellbar ist, wird eine Trennschraube 16 oder dergleichen getrennt und eine Abdeckung 22 abgestoßen. Dadurch kann sich nun der Fallschirm 17 am jeweiligen Leuchtkörper 7 entfalten.After the lapse of the delay time, which is adjustable for example by the
Nach Ablauf der Zeit, die durch das zweite Verzögerungselement 12 eingestellt ist, werden die eigentlichen pyrotechnischen Leuchtsätze 19 entzündet. Die Laufzeiten der zweiten Verzögerungselemente 12 unterscheiden sich bei den Leuchtkörpern 7 der Ebenen 14, 15. Je nach Auslegung des Geschosses 1 beginnen die Leuchtsätze 7 der Ebene 14 bzw. 15 zuerst abzubrennen und das Gefechtsfeld 20 zu beleuchten. Durch die Streuung 21 der Leuchtkörper 7 nach dem Ausstoß aus der Geschosshülle 2 ist das beleuchtete Gefechtsfeld 20 größer als die durch einen einzelnen Leuchtkörper 7 beleuchtete Fläche 24. Die Verzögerungselemente 12 der Leuchtkörper 7 der verschiedenen Ebenen 14, 15 sind so aufeinander abgestimmt, dass die Leuchtsätze 19 der Ebene 14, 15 entzündet werden, bevor die Leuchtkörper 7 der anderen Ebene anfangen zu leuchten. Durch diese Verzögerung kann die Gesamtbeleuchtungsdauer erhöht werden im Vergleich zu herkömmlichen Leuchtsystemen.After the time has elapsed, which is set by the
Es versteht sich, dass anstelle des pyrotechnischen Leuchtsatzes 19 auch LEDs verwendet werden können. Hier könnte dann auf eine doppelstufige Verzögerungseinrichtung (11, 12) in der beschriebenen Form verzichtet werden, da eine einfache ausreichend ist.It is understood that LEDs can be used instead of the
