Description

Die vorliegende Erfindung betrifft Signalsterne, wie sie insbesondere in Fallschirmpatronen verwendet werden.The present invention relates to signal stars, as are used in particular in parachute cartridges.

Die Signalsterne können aber auch bei anderen Signalpatronen eingesetzt werden.The signal stars can also be used with other signal cartridges.

Derartige Fallschirmpatronen oder Leuchtpatronen werden bei zivilem oder miltärischem Einsatz aus Schußapparaten abgefeuert und brennen z. B. zur sogenannten Vorfeldbeleuchtung am Fallschirm hängend in vorgegebener Zeit ab. Um den Abbrand ausreichend lang zu gestalten bzw. um ein zu schnelles Durch­brennen des Signalsterns zu verhindern, weisen herkömmliche Munitionen folgenden Aufbau auf.Such parachute cartridges or light cartridges are fired from civilian or military use from guns and burn z. B. from the so-called apron lighting on the parachute in a predetermined time. In order to make the burn-up sufficiently long or to prevent the signal star from burning too quickly, conventional ammunitions have the following structure.

Der eigentliche Stern besteht aus einem gepreßten Leuchtsatz, der von einem Mantel umgeben in einer Aluminiumhülse und in einem Signalträger untergebracht ist. Der Stern selbst ruht dabei auf einer Ausstoßladung, unter der der Verzögerungssatz und Treibsatz angeordnet sind. Letztere können von einem Leitwerk umgeben sein und befinden sich vor dem Abschuß in einer Patronenhülse mit Treibladung.The actual star consists of a pressed light set, which is surrounded by a jacket in an aluminum sleeve and housed in a signal carrier. The star itself rests on an exhaust charge, under which the deceleration rate and propellant rate are arranged. The latter can be surrounded by a tail unit and are located in a cartridge case with propellant charge before firing.

Die erwähnte Ummantelung besteht üblicherweise z. B. aus Papier, Aluminium oder PVC und dämpft die Abbrandgeschwindigkeit des Sterns.The sheath mentioned usually consists, for. B. made of paper, aluminum or PVC and dampens the burning rate of the star.

Nachteilig sind dabei u. a. ein relativ hoher durch die Ummantelung bedingter Leuchtstärkeverlust und gleichzeitig ein eng kegelförmiges Abbrandbild, wodurch aus ungünstigen Winkeln ein Erkennen erschwert wird. Zudem ist der Abbrand nicht rück­standsfrei, d. h. heiße Schlacke- oder Metallteile können zu Boden fallen und zu Verletzungen oder Bränden führen.Disadvantages are, among other things, a relatively high loss of luminosity due to the sheathing and, at the same time, a narrowly conical burn-off image, which makes detection more difficult from unfavorable angles. In addition, the burnup is not residue-free, ie hot slag or metal parts can fall to the floor and lead to injuries or fires.

Die vorliegende Erfindung hat sich daher die Aufgabe gestellt, Signalsterne derart zu verbessern, daß ihre Lichtleistung bedeutend erhöht, daß das Herabfallen heißer Rückstände weitgehend vermieden und daß das Abbrandbild vergrößert wird. Die Lichtleistung herkömmlicher Sterne (gelb) liegt bei ca. 40.000 bis 45.000 cd.The object of the present invention is therefore to improve signal stars in such a way that their light output is increased significantly, that hot residues are largely avoided and that the burn-up image is enlarged. The light output of conventional stars (yellow) is around 40,000 to 45,000 cd.

Die Lösung dieser Aufgabe gelingt mit einem Signalstern für Leuchtsignale, insbesondere mit einem Durchmesser von 22 mm und einer Mindest-Brennzeit von 12 Sekunden, bestehend aus einem gepreßten Leuchtsatz, bei dem erfindungsgemäß der Leuchtsatz vorzugsweise aus einer 26,5 mm Pistole verschossen wird, vorzugsweise an einem Fallschirm zur Erde sinkt, die Brenndauer und die Konstruktion so bemessen sind, daß der Leuchtsatz ausgebrannt ist, bevor der Boden berührt ist, die Leuchtstärke mindestens 90.0000 cd. beträgt und der Fallschirm nicht durch Hitzeentwicklung beschädigt wird.This object is achieved with a signal star for light signals, in particular with a diameter of 22 mm and a minimum burning time of 12 seconds, consisting of a pressed light set, in which, according to the invention, the light set is preferably fired from a 26.5 mm pistol, preferably on a parachute sinks to the ground, the burning time and the construction are dimensioned such that the light set burned out before it touched the ground, the light intensity was at least 90,000 cd. and the parachute is not damaged by heat.

Der Leuchtsatz weist insbesondere eine Beschichtung entweder aus einer Lackschicht auf, die auf dem Signalstern aufgetragen ist oder aus mit einer Klebschicht versehenen Folien- oder Papier­lage, die auf den Leuchtsatz aufgeklebt ist.The light set has, in particular, a coating either of a lacquer layer which is applied to the signal star or of a layer of film or paper provided with an adhesive layer which is glued to the light set.

Überraschenderweise wurden für die erfindungsgemäßen Signalsterne Lichtausbeuten von 100.000 cd und darüber gemessen, d. h. die Lichtleistung konnte mehr als verdoppelt werden, wobei die Abbrandzeiten nicht verkürzt sind, der Abbrand ist außerdem weitgehend rückstandsfrei, herabfallende heiße Teile konnten nicht beobachtet werden.Surprisingly, light yields of 100,000 cd and above were measured for the signal stars according to the invention, i. H. the light output could be more than doubled, whereby the burn-up times are not shortened, the burn-up is also largely residue-free, and falling hot parts could not be observed.

Insbesondere im Falle der Verwendung einer Lackschicht als Ummantelung trat ein Durchschlagen der Flamme bzw. ein vorschnel­les Verbrennen nicht auf.In particular, in the case of using a lacquer layer as a sheathing, the flame did not break through or prematurely burned.

Ein nahezu gleich gutes Ergebnis wird erzielt, wenn Papier oder Folienmaterial auf den Stern geklebt wird. Eine erschöpfende Begründung für diese Effekte kann nicht gegeben werden. Es wird jedoch vermutet, daß das Verdampfen der Lack- oder Klebeschicht die anhaftende Folie günstiger und rückstandsfrei zu verbrennen in der Lage sind, als wenn der Leuchtsatz in einer Aluminiumhülse verpreßt wird.An almost equally good result is achieved if paper or foil material is glued to the star. An exhaustive justification for these effects cannot be given. However, it is believed that the evaporation of the paint or adhesive layer the adhesive film is able to burn cheaper and residue-free than if the light set is pressed in an aluminum sleeve.

Der Lacküberzug ergibt einen idealen Abschluß von Luftfeuchtig­keit bei der Lagerung.The varnish coating provides an ideal seal of air humidity during storage.

Bei der Verwendung von mit einer Klebeschicht verwendetem Papier oder Folie kann auf Handelsprodukte zurückgegriffen werden.Commercial products can be used when using paper or film with an adhesive layer.

Bei der Verwendung von Kunstharzlack haben sich Schichtdicken von etwa 0,1 bis 0,15 besonders gut bewährt, wobei es auch auf die Pigmenthaltigkeit ankommt, d. h. die Lacke sollen pigmenthaltig sein, vorzugsweise in Menge von 20-80 Vol % . Vorgeschlagen werden vornehmlich Alkydharzlack, Chlorkautschuklack, Epoxidharz­lack, Acrylatharzlack, Öllack, Nitrolack, Polyesterlack, Polyurethanlack sowie die sogenannten Kombinationslacke.When using synthetic resin lacquer, layer thicknesses of approximately 0.1 to 0.15 have proven particularly effective, with the pigment content also being important, i. H. the paints should contain pigment, preferably in an amount of 20-80% by volume. Alkyd resin lacquer, chlorinated rubber lacquer, epoxy resin lacquer, acrylate resin lacquer, oil lacquer, nitro lacquer, polyester lacquer, polyurethane lacquer and the so-called combination lacquers are mainly proposed.

Vorzuziehen ist die Verwendung eines pigmenthaltigen farbigen Lackes, da so gleichzeitig die Leuchtfarbe des Sternes gekenn­zeichnet werden kann.It is preferable to use a pigmented colored varnish, because this way the luminous color of the star can be identified at the same time.

Herkömmliche Signalsterne werden aus dem Satz unter Drücken von üblicherweise 3000 bar gepreßt. Dabei entstehen häufig Falten in der Aluminiumhülle, die zur Rissbildung im Satz führen, d. h. dieser Signalstern würde nach dem Entfernen der Aluminiumhülle auseinanderfallen.Conventional signal stars are pressed from the set under pressures of usually 3000 bar. This often creates wrinkles in the aluminum shell, which lead to crack formation in the set, i.e. H. this signal star would fall apart after the aluminum shell was removed.

Diese Risse verursachen beim Abbrand ein Splittern und führen außerdem zu Brennzeitverkürzungen.These cracks cause splintering when they burn and also lead to shorter burning times.

Die vorliegende Erfindung schlägt daher eine andere Vorgehens­weise zu deren Herstellung vor, um einmal einen reproduzierbaren vorgegebenen Abbrand zu erzielen und zum anderen ihre Handhab­barkeit für eine Lackierung zu verbessern.The present invention therefore proposes a different procedure for the production thereof, in order to achieve a reproducible predetermined burn-up on the one hand and on the other hand to improve its manageability for painting.

Die erfindungsgemäßen Signalsterne bestehen hierzu aus einem verpreßten Granulat. Letzteres wird in einfacher Weise dadurch erhalten, daß der Satz mit einem Bindemittel vermischt und geknetet wird. Nach anschließendem Granulieren erhält man preßfähige Produkte. Der Preßdruck muß dabei wesentlich höher sein als herkömmlich und bei üblichen Abmessungen etwa 20 bis 40 to betragen.For this purpose, the signal stars according to the invention consist of a compressed granulate. The latter is obtained in a simple manner by mixing and kneading the set with a binder. After subsequent granulation, pressable products are obtained. The pressure must be much higher than conventional and about 20 to 40 tons with usual dimensions.

Die so hergestellten Signalsterne sind ausgesprochen stabil und frei von Rissen. Ihr Abbrandverhalten ist homogen, sie eignen sich in besonderer Weise zur Anbringung der Ummantelung in der oben beschriebenen Weise.The signal stars produced in this way are extremely stable and free of cracks. Their combustion behavior is homogeneous, they are particularly suitable for attaching the casing in the manner described above.

Herkömmliche Sätze bestehen z. B. aus einem Sauerstoffträger, der gleichzeitig Farbgebungskomponente sein kann, einem Brennstoff (Metallpulver, wie Magnesium) und einem farbver­tiefenden Abbrandmoderator. Dieser Abbrandmoderator ist eine stark Chlor-haltige Substanz, wie z. B. nachchloriertes PVC und wird in Mengen von ca. 10 % zugefügt. Überraschenderweise hat sich im Zusammenhang mit der vorliegenden Erfindung herausge­stellt, daß die Leuchtkraft eines Signalsternes in Abwesenheit von Chlor-abgebenden Substanzen verbessert werden kann, wenn dem Satz anstelle der herkömmlichen Moderatoren Polyolefin in Mengen von lediglich ca. 3 Gew.-% zugegeben werden. Die Helligkeit steigert sich dabei um mindestens 10 % ohne Beeinträchtigung der Moderation.Conventional sentences exist e.g. B. from an oxygen carrier, which can also be a coloring component, a fuel (metal powder, such as magnesium) and a color-deepening combustion moderator. This combustion moderator is a highly chlorine-containing substance, such as. B. post-chlorinated PVC and is added in amounts of about 10%. Surprisingly, it has been found in connection with the present invention that the luminosity of a signal star can be improved in the absence of chlorine-releasing substances if the set instead of the conventional moderators is added in amounts of only about 3% by weight. The brightness increases by at least 10% without impairing the moderation.

Eine Verlängerung der Brenndauer läßt sich in einfacher Weise auch dadurch erreichen, daß dem Leuchtsatz inerte mineralische Stoffe, wie insbesondere Metalloxide als Moderatoren zugegeben werden. Insbesondere haben sich hierfür Silicium und Titanoxide bewährt.An extension of the burning time can also be achieved in a simple manner by adding inert mineral substances, such as in particular metal oxides, as moderators to the light set. Silicon and titanium oxides have proven particularly useful for this purpose.

Die mineralischen Stoffe können in Mengen von 3-6 Gew.-% zugegeben werden, wobei eine Zunahme an 6 % mineralischen Materials eine Brenndauerverlängerung von etwa 30 % mit sich bringt.The mineral substances can be added in amounts of 3-6% by weight, an increase in 6% mineral material resulting in an increase in the burning time of approximately 30%.

Insbesondere werden die erfindungsgemäßen Leuchtsätze in Fallschirmpatronen verwendet. Dabei kommt es in etwa 4 % der Fälle zu einem Brennen der Fallschirmleinen. Um die Leinen des Schirmes zu schützen, wird vorgeschlagen, im Bereich der Aufhängung des Schirmes eine Sperrschicht aus nicht brennbaren Oxiden, vorzugsweise aus Natriumnitrat anzuordnen.In particular, the light sets according to the invention are used in parachute cartridges. This causes the parachute lines to burn in about 4% of the cases. In order to protect the lines of the screen, it is proposed to arrange a barrier layer of non-combustible oxides, preferably of sodium nitrate, in the area of the suspension of the screen.

In besonders vorteilhafter Weise können die Aufhängungen und die Sperrschicht beim Preß- oder Gießvorgang mit eingearbeitet werden.In a particularly advantageous manner, the suspensions and the barrier layer can be incorporated during the pressing or casting process.

Ein wirksamer zusätzlicher Schutz der Fallschirmleinen wird weiterhin erfindungsgemäß dadurch erreicht, daß in die Fall­schirmleinen Metallfäden oder Glasfasergewebe eingesponnen wird oder daß diese gänzlich daraus bestehen.An effective additional protection of the parachute lines is further achieved according to the invention in that metal threads or glass fiber fabric is spun into the parachute lines or that these consist entirely of them.

Für die Befestigung des Fallschirmes wird vor dem Verpressen des Satzes eine sog. Stockokappe in diesen eingelegt, durch die ein Splint geführt und aufgespreizt ist. Zwischen der Stockokappe und der Splintöse befindet sich dabei eine Lochscheibe aus Metall, auf die der gesamte Satz gefüllt und gepreßt wird. Nach dem Entformen bildet die Lochscheibe den Sternabschluß nach oben zum Fallschirm hin.To attach the parachute, a so-called stocko cap is inserted into the parachute before it is pressed, through which a split pin is guided and spread. There is a metal perforated disc between the stock cap and the cotter pin, on which the entire set is filled and pressed. After removal from the mold, the perforated disc forms the star closure towards the parachute.

Diese Art der Befestigung ist erheblich weniger aufwendig, als die herkömmliche, bei der die Befestigung durch Einrollen des oberen Randes, z. B. der Ummantelung, auf die Abdeckscheibe vorgenommen werden muß.This type of attachment is considerably less expensive than the conventional one, in which the attachment by rolling up the upper edge, for. B. the casing, must be made on the cover plate.

Im nachstehenden Ausführungsbeispiel wird die Herstellung eines mantellosen Signalsternes der Farbe gelb beschrieben.In the following exemplary embodiment, the production of a coatless signal star of the color yellow is described.
