Description

Die Erfindung betrifft eine Vorrichtung zur Bergung eines Trefferanzeige-Sensors, der in einem zur Darstellung von Luftzielen dienenden und mit einem Bergungssystem mit Fallschirm und einer Schleppseilanlenkung zur Befestigung eines Schleppseiles versehenen Schleppzielkörper lösbar angeordnet ist.The invention relates to a device for the rescue of a hit display sensor, which is detachably arranged in a serving for displaying air targets and provided with a rescue system with a parachute and a tow rope linkage for fastening a tow rope.

Derartige Schleppzielkörper sind allgemein bekannt und in verschiedenen Luftwaffen eingeführt. Diese Schleppzielkörper werden während eines Luft/Luft-Übungsschießens mit Rohrwaffen zur Darstellung eines Luftzieles mittels eines Schleppseiles hinter einem Luftfahrzeug hergezogen. Im wesentlichen besteht der Schleppzielkörper aus einem Mittelholm mit daran angeordneten kleineren oder größeren Tragflächen und einem darauf angeordneten Trefferanzeige-Sensor. Beide Geräte, Schleppzielkörper und Trefferanzeige-Sensor, sind bisher als Einweg-bzw. Verlustgeräte konzipiert. Das heisst, dass entweder der Schleppzielkörper nach dem Einsatz vom schleppenden Luftfahrzeug getrennt und nicht mehr geborgen wird oder mit einem Fallschirm zu Boden gleitet.Such target bodies are well known and are used in various air forces. These tow target bodies are pulled behind an aircraft during an air / air practice shooting with barrel weapons to represent an air target by means of a tow rope. The towed target body essentially consists of a central stringer with smaller or larger wings arranged thereon and a hit display sensor arranged thereon. Both devices, tow targets and hit display sensor, are so far as one-way or. Loss devices designed. This means that either the tow target is separated from the towing aircraft after use and is no longer recovered, or it glides to the ground with a parachute.

Beispielsweise ist aus der DE-PS 25 11 984 ein Bergungssystem für geschleppte Flugzielkörper bekannt, das aus einem Fallschirm besteht, dessen Auslösevorrichtung bei Nachlassen der Spannung des Schleppseils wirksam wird. Hierbei ist das am Zielflugkörper befestigte Ende des Schleppseils elektrisch leitend und hat elektrischen Kontakt zu einer Steuerschaltung im Zielflugkörper. An seiner Kontur befindet sich ein gegenüber seiner Haut isolierter, elektrisch leitender Kontaktring. Bei Trennung des Schleppseils berührt es den Kontaktring und schliesst einen aus Kontaktring, Schleppseil und Steuerschaltung bestehenden Schaltkreis, wodurch der Fallschirm ausgelöst wird.For example, from DE-PS 25 11 984 a salvage system for towed flying targets is known, which consists of a parachute, the triggering device is effective when the tension of the tow rope is released. The end of the tow rope attached to the target missile is electrically conductive and has electrical contact with a control circuit in the target missile. At its contour there is an electrically conductive contact ring that is insulated from its skin. When the tow rope is disconnected, it touches the contact ring and closes a circuit consisting of a contact ring, tow rope and control circuit, which triggers the parachute.

Aus der GB-A-941 909 ist ein Schleppzielkörper zur Darstellung von Luftzielen mit einem Detektor, mit einem Bergungssystem mit Fallschirm, das durch Kappen des Schleppseiles aktiviert wird und mit einer Schleppseilanlenkung zur Befestigung eines Schleppseils bekannt. Diese Vorrichtung bildet den Oberbegriff des Anspruchs 1. Der Schleppzielkörper schwebt nach seinem Einsatz im wesentlichen vollständig am Fallschirm auf die Erde zurück.From GB-A-941 909 a towing target body for displaying air targets with a detector, with a salvage system with a parachute, which is activated by cutting the tow rope, and with a tow rope linkage for fastening a tow rope is known. This device forms the preamble of claim 1. After being used, the towed target body hovers essentially completely back onto the earth on a parachute.

Aufgabe der Erfindung ist es, eine Vorrichtung zu schaffen, mit welcher der relativ kleine, leichte und kostenträchtige Trefferanzeige-Sensor mit zugehöriger Elektronik vom grossen, schweren und häufig stark zerstörten und für weitere Einsätze unbrauchbaren Schleppzielkörper getrennt und als wiederverwendbares Gerät geborgen werden kann.The object of the invention is to provide a device with which the relatively small, light and costly hit display sensor with associated electronics can be separated from the large, heavy and often severely destroyed and useless for further use and can be recovered as a reusable device.

Erfindungsgemäß wird die gestellte Aufgabe durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention, the object is achieved by the characterizing features of claim 1. Advantageous further developments result from the subclaims.

Der Vorteil der Erfindung besteht darin, daß der Trefferanzeige-Sensor sowohl durch eine mechanische Aktivierung der Bergungselektronik automatisch, als auch durch eine funkelektronische Aktivierung mittels Empfangs- und Bergungselektronik vom Schleppzielkörper trennbar ist. Damit ist es möglich, den Trefferanzeige-Sensor zusammen mit dem Bergungssystem vom Schleppzielkörper so zu trennen, daß nach der Landung oder Wasserung der Sensor unbeschädigt und für einen erneuten Einsatz wiederverwendbar bleibt. Dadurch ergibt sich eine beträchtliche Einsparung an wiederzubeschaffenden Geräten und der damit verbundenen erheblichen Kosten.The advantage of the invention is that the hit display sensor can be separated from the towing target body automatically by mechanical activation of the salvage electronics as well as by radio-electronic activation by means of reception and salvage electronics. This makes it possible to separate the hit display sensor together with the recovery system from the towing target body so that the sensor remains undamaged after landing or watering and can be reused for a new use. This results in a considerable saving in devices to be replaced and the associated considerable costs.

Das Bergungssystem mit der darin angeordneten Bergungs- und/oder Empfangselektronik ist am Schleppzielkörper durch pyrotechnische Trennelemente, z.B. Sprengschrauben oder Sprengnieten befestigt. Nach Kappen des Schleppseiles vom Luftfahrzeug wird das Schleppseil wegen seines zum Schleppzielkörper relativ größeren Luftwiderstandes und seiner geringeren Masse vom Schleppzielkörper unterholt. Dabei legt es sich an der Oberseite des Schleppzielkörpers an wobei seine Lage zum Anlenkpunkt definiert ist. Am Anlenkpunkt befindet sich die Kontaktschaltung in Form eines Mikroschalters. Eine am Schleppzielkörper angeordnete und mit dem Schleppseil und deren Anlenkung verbundene drehbare Kontaktleiste dient als Signalgeber, der von einem Berührungsfühler automatisch geschaltet wird. Die dadurch bewirkte Aktivierung der Bergungselektronik gibt die Zündimpulse für das Durchtrennen der Solbruchstellen der pyrotechnischen Trennelemente. Nach erfolgtem Lösen der Verbindungen trennt sich unter Einwirkung des Luftwiderstandes das Bergungssystem zusammen mit dem Trefferanzeige-Sensor vom Schleppzielkörper. Zugleich wird ein darin verstautes Fallschirmsystem ausgezogen und freigegeben. Die am Fallschirm befestigte bzw. hängende Bergungselektronik mit dem Trefferanzeige-Sensor gleiten daran mit vorbestimmter Sinkgeschwindigkeit zu Boden. Nach erfolgter Bergung kann sowohl der Trefferanzeige-Sensor als auch die Bergungselektronik für einen weiteren Einsatz aufbereitet und wiederverwendet werden.The salvage system with the salvage and / or reception electronics arranged in it is attached to the towing target body by pyrotechnic separating elements, for example explosive screws or explosive rivets. After the tow rope has been cut from the aircraft, the tow rope is overtaken by the tow target body because of its relatively greater air resistance to the tow target body and its lower mass. It attaches itself to the top of the towing target, its position to the articulation point being defined. Located at the pivot point the contact circuit in the form of a microswitch. A rotatable contact bar, which is arranged on the towing target body and connected to the tow rope and its linkage, serves as a signal generator, which is automatically switched by a touch sensor. The resulting activation of the salvage electronics gives the ignition impulses for cutting through the brine fractures of the pyrotechnic separating elements. After the connections have been loosened, the salvage system, together with the hit display sensor, separates from the tow target under the influence of air resistance. At the same time, a parachute system stowed in it is pulled out and released. The rescue electronics attached to the parachute or hanging with the hit display sensor slide thereon at a predetermined rate of descent to the ground. After the salvage has taken place, both the hit display sensor and the salvage electronics can be prepared for further use and reused.

Um den Bergungsvorgang des Trefferanzeige-Sensors und der Bergungselektronik auch ohne die vorher beschriebene automatische Aktivierung, also ohne Abwurf des Schleppzuges zu bewirken, ist das Bergungssystem mit einer zusätzlichen Empfangselektronik bestückt. Die dadurch ermöglichte kommandierte Bergung des Trefferanzeige-Sensors mit Elektronik wird erforderlich, wenn für den Abwurf der Geräte kein geeignetes Areal verfügbar ist oder technische Schwierigkeiten vorliegen. In solchen Fällen müssen die Geräte über Land geflogen und von einem am Boden oder an Bord des schleppenden Luftfahrzeuges installierten Kommandosender aus ein Bergungssignal an die Bergungselektronik im Schleppzielkörper gesendet werden. Hierzu wird über eine am Bergungssystem in stallierte Antenne sowie einer Empfangselektronik und einem Decoder ein Signal als Zündimpuls an die pyrotechnischen Trennelemente gegeben, worauf diese gezündet werden und der darauffolgende Trenn- und Bergungsvorgang gleich dem vorbeschriebenen abläuft.In order to bring about the recovery process of the hit display sensor and the recovery electronics without the automatic activation described above, i.e. without the tow truck being dropped, the recovery system is equipped with additional receiving electronics. The resulting commanded salvage of the hit display sensor with electronics becomes necessary if the device is not suitable for dropping Area is available or there are technical difficulties. In such cases, the devices must be flown overland and sent from a command transmitter installed on the ground or on board the towing aircraft to the salvage electronics in the towing target body. For this purpose, a signal is sent as an ignition pulse to the pyrotechnic separating elements via an antenna installed in the salvage system, as well as receiving electronics and a decoder, whereupon these are ignited and the subsequent separation and salvage process proceeds as described above.

Für den automatischen und über den funkelektronischen (kommandierten) Bergungsvorgang ist im Bergungssystem eine eigene Stromversorgung (z.B. Batterie) angeordnet.
Das Bergungssystem arbeitet völlig autonom. Eine Änderung der Form gegenwärtiger Trefferanzeige-Sensoren bedarf es deshalb nicht.A separate power supply (eg battery) is arranged in the recovery system for the automatic and via the radio-electronic (commanded) recovery process.
The recovery system works completely autonomously. It is therefore not necessary to change the shape of current hit display sensors.

Ausführungsbeispiele sind folgend beschrieben und durch Skizzen erläutert.Exemplary embodiments are described below and explained by sketches.

Aus Figur 1 ist ein Schleppzielkörper 1 mit Bergungssystem 2 in seitlicher und in der Ansicht von oben ersichtlich. Der Schleppzielkörper 1 weist auf seiner Oberseite eine Schleppseilankenkung 3 auf, mit welcher ein von einem in der Figur nicht gezeigten Luftfahrzeug gezogenes Schleppseil 4 verbunden ist. Ebenfalls auf seiner Oberseite ist hinter der Schleppseilanlenkung 3 das Bergungssystem 2 innerhalb eines Gehäuses 5 und auf diesem ein Trefferanzeige-Sensor 6 angeordnet. Beide sind auf dem Schleppzielkörper 1 mittels pyrotechnischer Trennelemente 7 (z.B. mit Sollbruchstellen versehene Sprengschrauben oder Sprengnieten) befestigt. Das Bergungssystem 2 enthält unter anderem eine Bergungs- und Empfangselektronik 8, 8ʹ bestehend aus Antenne, Empfänger und Decoder, eine Stromversorgung 9 (z.B. Batterie), ein Fallschirmsystem 10, eine Kontaktschaltung 11 und einen als Signalgeber ausgebildeten Berührungsfühler 12. Im vorderen Teil des Gehäuses 5, in Schlepp-bzw. Flugrichtung, ist das Fallschirmsystem 10 zusammen mit der im hinteren Bereich angeordneten Bergungs- und/oder Empfangselektronik 8 und Stromversorgung 9 zusammen mit dem Trefferanzeige-Sensor 6 fest verbunden. Die Außenkontur des Bergungssystems 2 bzw. dessen Gehäuse 5 und die des Trefferanzeige-Sensors 6 sind aufeinander abgestimmt. Der als Signalgeber ausgebildete Berührungsfühler 12 ist nahe der Schleppseilanlenkung 3 angeordnet, mit welchem die Lage des Schleppseiles 4 relativ zum Schleppzielkörper 1 festgestellt wird. Um ein sicheres Funktionieren der mechanischen Aktivierung durch den Berührungsfühler 12 zu gewährleisten, ist an zwei Seilkauschen (nicht näher gezeigt), an die das Schleppseil 4 hängt, eine Kontaktleiste 13 angeordnet. Nach Kappen des Schleppseiles 4 dreht sicht die Kontaktleiste 13 beim Zurückbleiben des Schleppseiles 4 auf den berührungsfühler 12 und löst die Aktivierung für den Bergungsablauf aus.1 shows a towed target body 1 with a salvage system 2 in a side view and in a view from above. The tow target body 1 has on its upper side a tow rope lowering 3, to which a tow rope 4 pulled by an aircraft, not shown in the figure, is connected. Also on its upper side, behind the tow rope linkage 3, the recovery system 2 is arranged within a housing 5 and a hit indicator sensor 6 is arranged thereon. Both are attached to the drag target body 1 by means of pyrotechnic separating elements 7 (for example explosive screws or rivets provided with predetermined breaking points). The recovery system 2 contains, among other things, recovery and reception electronics 8, 8onik consisting of antenna, receiver and decoder, a power supply 9 (eg battery), a parachute system 10, a contact circuit 11 and a touch sensor 12 designed as a signal transmitter Part of the housing 5, in towing or. Direction of flight, the parachute system 10 is firmly connected together with the recovery and / or reception electronics 8 and power supply 9 arranged in the rear area together with the hit display sensor 6. The outer contour of the recovery system 2 or its housing 5 and that of the hit display sensor 6 are matched to one another. The touch sensor 12, which is designed as a signal transmitter, is arranged near the tow rope linkage 3, with which the position of the tow rope 4 relative to the tow target body 1 is determined. In order to ensure a safe functioning of the mechanical activation by the touch sensor 12, a contact strip 13 is arranged on two thimbles (not shown in more detail) to which the tow rope 4 hangs. After the tow rope 4 has been cut, the contact strip 13 rotates when the tow rope 4 remains on the touch sensor 12 and triggers the activation for the recovery process.

Aus den Figuren 2a bis d ist der Bergungsablauf des Bergungssystems 2 zusammen mit dem Trefferanzeige-Sensor 6, der Bergungselektronik 8 und Stromversorgung 9 in einzelnen Sequenzen ersichtlich.
Figur 2a zeigt den Schleppzielkörper 1 in Schleppstellung, in Figur 2b ist das gekappte Schleppseil 4 durch die Unterholung des Schleppzielkörpers 1 und ihres Luftwiderstandes zurückgefallen und liegt mit der Kontaktleiste 13 auf dem Berührungsfühler 12 auf (Figur 2c). Durch die dabei erfolgte Aktivierung wurden die pyrotechnischen Trennelemente 7 gezündet und das Berungssystem 2 zusammen mit dem Trefferanzeige-Sensor 6 vom Schleppzielkörper 1 gelöst, sowie der Fallschirm 14 freigegeben. In Figur 2d schwebt das Bergungssystem 2 und der Trefferanzeige-Sensor am Fallschirm 14 hängend zu Boden. Der Schleppzielkörper 1 geht verloren. Der Ablauf erfolgt automatisch.The salvage sequence of the salvage system 2 together with the hit display sensor 6, the salvage electronics 8 and the power supply 9 can be seen in individual sequences from FIGS. 2a to d.
FIG. 2a shows the towed target body 1 in the towed position, in FIG. 2b the cut tow rope 4 has fallen back due to the undertaking of the towed target body 1 and its air resistance and lies with the contact strip 13 on the touch sensor 12 (Figure 2c). As a result of the activation, the pyrotechnic separating elements 7 were ignited and the detection system 2 together with the hit display sensor 6 were released from the towed target body 1, and the parachute 14 was released. In FIG. 2d, the salvage system 2 and the hit display sensor are suspended on the parachute 14 to the ground. The target body 1 is lost. The process is automatic.

Die Figuren 3a bis c zeigen den Bergungsablauf nach einem vom Luftfahrzeug oder vom Boden aus gegebenen Kommando. Hierbei wird das Schleppseil 4 nicht am Luftfahrzeug gekappt. Nach erfolgtem Trennen des Bergungssystem mit dem Trefferanzeige-Sensor verläuft der Trennablauf gleich dem vorher beschriebenen; die Geräte 2, 6, 8ʹ, 9, 10 gleiten am Fallschirm nieder.Figures 3a to c show the salvage procedure after a command given by the aircraft or from the ground. Here, the tow rope 4 is not cut on the aircraft. After the salvage system has been separated with the hit display sensor, the separation process is the same as that previously described; the devices 2, 6, 8ʹ, 9, 10 slide down on the parachute.

Das aus Figur 4 ersichtliche prinzipielle Blockschaltbild zeigt eine Schaltanordnung des Bergungssystem 2 für eine automatische (gemäß Figuren 2a bis d) und eine kommandierte (Figuren 3a bis c) Aktivierung und Auslösung des Fallschirmsystems 10 (Figuren 2 und 3). Das Kommandosignal gelangt über die Antenne 15 in die Empfangs- bzw. Auslöseelektronik 8, 8ʹ in die gegebenenfalls (bei Kappen des Schleppseiles 4 in Figur 3) noch ein Signal vom Seillagen-Berührungsfühler 12 eingegeben wird und von wo der Zündimpuls an die pyrotechnischen Trennelemente 7 abgegeben wird.The basic block diagram shown in FIG. 4 shows a switching arrangement of the recovery system 2 for automatic (according to FIGS. 2a to d) and commanded (FIGS. 3a to c) activation and triggering of the parachute system 10 (FIGS. 2 and 3). The command signal arrives via the antenna 15 in the receiving or triggering electronics 8, 8 ', in which, if necessary (when the tow rope 4 is cut in FIG. 3), a signal from the rope layer contact sensor 12 is entered and from where the ignition pulse is delivered to the pyrotechnic separating elements 7.

Je nach Einsatzvariante kann das Bergungssystem 2 reduziert werden. Zum Beispiel bei rein passivem Bergungsbetrieb, bei dem die Bergungssequenz nach Kappen des Schleppseiles 4 ausgelöst wird, kann auf den Einsatz der Kommando-Empfangs-elektronik verzichtet werden. Desgleichen ist die Kontaktschaltung 11, der Berührungsfühler 12 und die Kontaktleiste 13 überflüssig, wenn feststeht, daß eine Bergung des Trefferanzeige-Sensors 6 und der übrigen Geräte ausschließlich durch ein Funkkommando eingeleitet werden soll.Depending on the application, the salvage system 2 can be reduced. For example, in the case of purely passive salvage operation, in which the salvage sequence is triggered after the tow rope 4 has been cut, the use of the command / receive electronics can be dispensed with. Likewise, the contact circuit 11, the touch sensor 12 and the contact strip 13 are superfluous if it is certain that a rescue of the hit display sensor 6 and the other devices should be initiated only by a radio command.
