Definitions
- the invention relates to a drone or a towed body for displaying a flight target with IR flares.
- towed bodies have been equipped with infrared burners (IR flares) for a long time and used for training and shelling with guided missiles which are equipped with IR seekers.
- IR flares are available in a wide range of effects on the market and are firmly attached to target drones or towed bodies in the rear area.
- the IR flares are ignited shortly before the missile is fired and simulate the seeker head of the missile for a limited time, the hot gas jet of a running aircraft engine. Since the missile probability of these guided missiles (even without a warhead) is very high, the target imaging means (drone or towed body) is usually lost with each use.
- the object of the invention is to ensure the reusability of the towed body or the drone when a flare is hit by a guided missile. This object is achieved by the subject matter of the main claim.
- the subclaims relate to advantageous refinements of the invention.
- the invention enables automatic lighting, ejection and towing a commercial IR flare.
- the IR flare burns off in a safe distance of approx. 8 m from the towed body, so that even with one Direct hit of the missile the tow body can be used again.
- Fig. 1 shows a tow body 1, at the rear of which there are IR flares. According to the invention, these infrared flares are ejected after ignition. The device used for this is explained below with reference to FIG. 2:
- An IR flare 12 used as the standard flare in a towed body series is used rotated by 180 ° into an ejection unit 6 until it stops.
- This IR-Flare has an open burner tube without its standard lighter.
- On the mechanical Fastening seam of the IR flare is by means of grub screw 18 Tow adapter 16 attached.
- the tow adapter 16 is over the thin tow rope 14 and the winding body 26 connected at the rear end 4 to the ejection unit 6.
- the tow rope 14 is directly in front of its connection 4 at the rear end guided a standard hitting line cutter 8, which over the pin 10 with the Tow 14 is activated (the exact overall functional sequence is shown below ) Will be explained.
- the active charge 28 of the IR flare is open to the kindling and ejection charge 32 arranged.
- the ignition and ejection charge 32 is directly from the receptacle 34 screwed into the rear of the ejection unit 6.
- the entire ejection unit 6 is screwed to the pyro base plate 2 by means of the screws 30.
- On the pyro base a total of 8 ejection units 50 (Fig. 3 and 4) are screwed, so that several Training approaches can take place.
- the active charge 28 of the IR flare is ignited at the same time, and the flare insert 12, which is sealed with the O-ring 22 to the ejection unit 6, is expelled toward the rear by the gas pressure which builds up.
- the safety wire 20 is attached for the air defense is torn off.
- the pin 10 of the reef line cutter 8 is pulled over the tow rope 14 in the first cm path.
- the inner winding 26 of the prefabricated tow rope winding 24 is completely pulled off to the intended drag length (approx. 8 m).
- the flare insert rotates through 180 ° so that the burner side points to the rear.
- the tow rope 14 is cut off at the lower end at the connection point 4 with a short time delay via the reef line cutter 8 activated at the committee.
- the burned-out flare insert 12 flies away with its tow rope 14 to the rear and makes room for the activation of a further flare. Since all further processes are mechanically and pyrotechnically coupled in the ejection unit 6 after the ejection charge 32 has been ignited, a very high level of reliability is achieved. If an ejection charge 32 fails, further ejection units can be ignited without any problems, since the flare insert 12 affected by the failure remains secured.
- the entire ejection unit 50 (FIG. 3) can be made ready for use again as often as desired by inserting a new IR flaring insert 12, tow rope winding body 24, a reef line cutter 8 and an ignition and ejection charge 32.
- the pyro unit 46 with all ejection units 50 is connected to the towed body structure 52 via a magnetically releasable coupling 48 via the structural frame 36. If, due to a malfunction (eg a reef line cutter), it is not possible to eject a towed IR flare, the entire pyro unit 46 can be ejected by releasing the clutch 48 before the towing body 52 is recovered. The electrical connection to the ignition and ejection charges 32 is automatically disconnected via the isolating plug interface 38. In order to enable a clean discharge, the entire pyro unit 46 is guided over guide tubes 40 and the guide rods 42 fastened to the structural frame 36. For preparation and storage in specially protected rooms, the entire pyro unit 46 can be removed very quickly via the central screw 44, which is easily accessible from the rear, without the need to activate electrical circuits (safety requirement).
- a malfunction eg a reef line cutter
Description
Da die Trefferwahrscheinlichkeit dieser Lenkwaffen (auch ohne Gefechtskopf) sehr hoch ist, geht in der Regel bei jedem Einsatz das Zieldarstellungsmittel (Drohne oder Schleppkörper) verloren.
Diese Aufgabe wird durch den Gegenstand des Hauptanspruchs gelöst. Die Unteransprüche betreffen vorteilhafte Ausgestaltungen der Erfindung.
Es zeigen:
- Fig. 1
- eine Gesamtansicht eines Schleppkörpers mit am Heck befindlichen Flares
- Fig. 2
- eine erfindungsgemässe Flare-Auswurfeinheit in Schnittdarstellung
- Fig. 3
- einen Pyro-Einsatz kombiniert mit einer Notabwurfeinrichtung
- Fig. 4
- die Flareauswurfeinheit von Fig. 2 in Heckansicht und
- Fig. 5
- einen Schleppkörper mit ausgeworfenem Flare während der Abbrennphase des Flares.
Die gesamte Auswurfeinheit 50 (Fig.3) läßt sich durch Einsetzen eines neuen IR-Flareinsatzes 12, Schleppseilwickelkörpers 24, eines Reffleinenschneiders 8 sowie einer Anzünd- und Auswurfladung 32 beliebig oft wieder einsatzbereit machen.
Zur Aufbereitung und zur Lagerung in speziell geschützten Räumen kann die gesamte Pyroeinheit 46 über die leicht von hinten zugängliche Zentralschraube 44 sehr schnell entfernt werden ohne dass elektrische Schaltkreise aktiviert werden müssen (Sicherheitsforderung).
