Description

Die Erfindung betrifft eine auf einem Wasserfahrzeug, insbesondere U-Boot, installierbare Ausbringvorrichtung zum Fieren einer schlauchartigen Unterwasser-Schleppantenne der im Oberbegriff des Anspruchs 1 definierten Art.The invention relates to a deployable on a watercraft, in particular submarine applicator for fibring a hose-like underwater towed antenna of the type defined in the preamble of claim 1.

Bei einer bekannten Ausbringvorrichtung für eine schlauchförmige Unterwasser-Schleppantenne ( DE 196 52 737 C1 ) weist die an der Schleppantenne angreifende Vortriebseinheit, die eine in Ausbringrichtung wirkende Zugkraft an der Schleppantenne erzeugt, ein Auslegerohr auf, durch das die Schleppantenne hindurchgeführt ist. An dem Auslegerohr ist eine Vielzahl von durch die Rohrwandung hindurchtretenden Einströmdüsen angeordnet, die an einer Hochdruck-Wasserpumpe angeschlossen sind. Mittels der Einströmdüsen wird zwischen der Rohrinnenwand des Auslegerohrs und der Schlauchhülle der Schleppantenne eine zum Ausbringende des Auslegerohrs gerichtete Wasserströmung erzeugt. Durch die starke Wasserströmung wird der im Auslegerohr sich momentan befindliche Abschnitt der schlauchförmigen Schleppantenne infolge der an der Schlauchhülle erzeugten Oberflächenreibung zum Ausbringende hin mitgenommen. Zusätzlich wird durch die Wasserströmung ein Schmiereffekt erreicht, da die Schlauchhülle der Schleppantenne von einem Wasserfilm umgeben ist und die Rohrinnenwand des Auslegerohrs nicht berührt, so daß keine nennenswerten, den Vortrieb der Schleppantenne bremsenden Reibungskräfte auftreten.In a known application device for a tubular underwater towed antenna ( DE 196 52 737 C1 ), the propulsion unit acting on the towed antenna, which generates a tensile force acting on the towed antenna in the application direction, has a boom pipe through which the towed antenna is passed. On the boom pipe a plurality of passing through the pipe wall inlet nozzles are arranged, which are connected to a high-pressure water pump. By means of the inlet nozzles, a water flow directed towards the discharge end of the delivery pipe is generated between the pipe inner wall of the delivery pipe and the hose casing of the towed antenna. Due to the strong water flow of the boom in the currently located portion of the tubular towed antenna is entrained due to the surface friction generated on the tubular casing to Ausbringende out. In addition, a lubricating effect is achieved by the flow of water, since the hose shell of the towed antenna is surrounded by a film of water and the tube inner wall of the boom pipe does not touch, so that no appreciable, the propulsion of the towed antenna braking frictional forces occur.

Es ist auch schon eine Ausbringvorrichtung mit einer Vortriebseinheit bekannt ( EP 0 124 133 B1 ), die zwei weichbeschichtete, gegenläufige Spillköpfe aufweist, zwischen denen die schlauchförmige Schleppantenne hindurchgeführt ist. Die motorisch angetriebenen Spillköpfe greifen auf beiden Seiten der Schleppantenne mit Reibschluß an und bewegen die Schleppantenne in Richtung zum Ausbringende des Auslegerohrs am Heck des U-Boots. Da die schlauchförmige Schleppantenne ein relativ biegeweiches Gebilde darstellt und der zwischen der Antriebsvorrichtung und dem Ausbringende des Auslegerohrs befindliche Antennenteil durch die Spillköpfe geschoben wird, kann ein stets störungsfreier Ausbringvorgang der Schleppantenne nicht zuverlässig sichergestellt werden. Zusätzlich ist die Schleppantenne durch die Spillköpfe einer hohen mechanischen Beanspruchung ausgesetzt, die zu eine frühzeitigen Verschleiß der Schlauchhülle der Schleppantenne führt und damit eine frühzeitige Unbrauchbarkeit der Schleppantenne verursacht.It is already known an application device with a propulsion unit ( EP 0 124 133 B1 ), which has two soft-coated, counter-rotating Spillköpfe between which the tubular towed antenna is passed. The motorized spill heads grip on both sides of the towed antenna with frictional engagement and move the towed antenna towards the delivery end of the boom pipe at the stern of the submarine. Since the tubular towed antenna is a relatively flexible structure and the antenna located between the drive device and the applicator end of the boom pipe part is pushed through the Spillköpfe, a consistently trouble-free Ausbringvorgang the towed antenna can not be reliably ensured. In addition, the towed antenna is exposed by the Spillköpfe a high mechanical stress, which leads to premature wear of the hose shell of the towed antenna, thus causing early usability of the towed antenna.

Der Erfindung liegt die Aufgabe zugrunde, eine Ausbringvorrichtung der eingangs genannten Art zu schaffen, die ein zuverlässig stör- und hemmungsfreies Fieren der Schleppantenne mit minimaler mechanischer Beanspruchung der Schleppantenne ermöglicht.The invention has for its object to provide a dispensing device of the type mentioned, which allows a reliable interference and inhibition-free Fieren the towed antenna with minimal mechanical stress on the towed antenna.

Die Aufgabe ist erfindungsgemäß durch die Merkmale im Anspruch 1 gelöst.The object is achieved by the features in claim 1.

Die erfindungsgemäße Ausbringvorrichtung hat den Vorteil, daß beim Fieren durch die Regeleinrichtung die Drehwinkelgeschwindigkeiten von Speichertrommel und Führungsrad auf die hinter dem Führungsrad auf die Schleppantenne in Ausziehrichtung wirkende Zugkraft so abgestimmt sind, daß die Zugkraft ausreicht, den von der Speichertrommel abgewickelten, sich jeweils zwischen Führungsrad und Speichertrommel befindlichen Abschnitt der Schleppantenne vom Führungsrad abzuziehen, so daß zwischen Führungsrad und Speichertrommel kein Durchhang der Schleppantenne entsteht und eine damit verbundene Gefährdung des Fiervorgangs verhindert wird. An der Schleppantenne tritt nur eine geringe, durch das Führungsrad bedingte, mechanische Reibung auf, die auch längerfristig nicht zu einer Beschädigung der Schlauchhülle der Schleppantenne führt.The dispensing device according to the invention has the advantage that when turning through the control device, the rotational angular velocities of storage drum and guide wheel on the behind the guide wheel on the towed antenna in the pull-pulling force are adjusted so that the tensile force sufficient, the unwound from the storage drum, each between guide wheel and storage drum located portion of the towed antenna to be deducted from the guide wheel, so that no sag of the towed antenna between the guide wheel and storage drum and a risk associated Fiervorgangs is prevented. Only a small, caused by the guide wheel, mechanical friction occurs on the towed antenna, which also does not lead to damage to the tubular casing of the towed antenna in the longer term.

Zweckmäßige Ausführungsformen der erfindungsgemäßen Ausbringvorrichtung mit vorteilhaften Weiterbildungen und Ausgestaltungen der Erfindung ergeben sich aus den weiteren Ansprüchen.Advantageous embodiments of the dispensing device according to the invention with advantageous developments and refinements of the invention will become apparent from the other claims.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist am Führungsrad mindestens ein Kraftmesser angeordnet, der die an der Schleppantenne angreifende Zugkraft sensiert. Die vom Kraftmesser gemessene Kraft ist als Führungsgröße der Regeleinrichtung zugeführt. Mittels des Kraftmessers wird die auf die Schleppantenne wirkende Kraft, deren Größe einer gewissen Schwankungsbreite unterliegt und beispielsweise nach dem Eintauchen des Ausbringendes der Schleppantenne in das Heckwasser des Wasserfahrzeugs stark ansteigen kann, sehr genau erfaßt.According to a preferred embodiment of the invention, at least one dynamometer is arranged on the guide wheel, which senses the pulling force acting on the towed antenna. The force measured by the dynamometer is supplied as a reference variable of the control device. By means of the dynamometer, the force acting on the towed antenna whose size is subject to a certain range of fluctuation and, for example, can rise sharply after immersion of the application end of the towed antenna in the stern water of the vessel, very accurately detected.

Da zum vollständigen Auftrommeln der Schleppantenne die Speichertrommel eine wesentliche axiale Länge hat und die Schleppantenne in mehreren Lagen auf die Speichertrommel aufgewickelt wird, ist der Speichertrommel ein Spulwagen zugeordnet, der parallel zur Trommelachse motorisch verfahrbar ist und ein drehgelagertes Spulenrad zum Führen der Schleppantenne trägt. Gemäß einer vorteilhaften Ausführungsform der Erfindung ist mittels der Regeleinrichtung auch die Vorschubgeschwindigkeit des Spulwagens in Abhängigkeit von der Drehwinkelgeschwindigkeit der Speichertrommel geregelt.Since the storage drum has a substantial axial length for complete drumming of the towed antenna and the towed antenna is wound onto the storage drum in several layers, the storage drum is associated with a reeling trolley which is motor-driven parallel to the drum axis and carries a rotatably mounted spool wheel for guiding the towed antenna. According to an advantageous embodiment of the invention, the feed rate of the winder is controlled in dependence on the rotational angular velocity of the storage drum by means of the control device.

Gemäß einer vorteilhaften Ausführungsform der Erfindung ist die Schleppantenne beim Fieren durch ein Führungsrohr mit Ein- und Austrittsöffnung hindurchgezogen und das Führungsrad unmittelbar an der Eintrittsöffnung des Führungsrohrs so angeordnet, daß der von dem Führungsrad tangetial ablaufende Schleppantennenabschnitt koaxial zur Normalen der Eintrittsöffnung, also koaxial zur Führungsrohrachse, ausgerichtet ist, so daß die vom Führungsrad ablaufende Schleppantenne direkt und ungehindert in das Führungsrohr einläuft.According to an advantageous embodiment of the invention, the towed antenna is pulled through a guide tube with inlet and outlet openings and the guide wheel is arranged directly at the inlet opening of the guide tube so that tangetial of the guide wheel trailing antenna section coaxial with the normal of the inlet opening, ie coaxially to the guide tube axis , is aligned so that the running of the guide wheel towed antenna enters directly and unhindered in the guide tube.

Gemäß einer vorteilhaften Ausführungsform der Erfindung greift die Vortriebseinheit am Ende der Schleppantenne an und weist ein mit der Schleppantenne fest verbundenes Antennen-Endstück auf, das eine Vielzahl von auf einem Seil axial im wesentlichen unverschieblich angeordneten, beabstandeten Formkörpern umfaßt, die zur Erzeugung eines Strömungswiderstands im Heckwasser des Wasserfahrzeugs ausgebildet sind. Dies hat den Vorteil, daß mit Eintauchen des Endstücks in das Heckwasser eine Zugkraft permanent an der Schleppantenne angreift, die von der Fahrzeuggeschwindigkeit beim Ausbringen der Schleppantenne abhängt und genügend groß ist, die Schleppantenne aus dem Führungsrohr auszuziehen.According to an advantageous embodiment of the invention, the propulsion unit engages the end of the towed antenna and has an antenna end fixedly connected to the towed antenna comprising a plurality of axially non-displaceably arranged on a rope, spaced moldings, which are used to generate a flow resistance in Rear water of the vessel are formed. This has the advantage that with the immersion of the tail in the rear water, a tensile force permanently on the towed antenna attacks, of the Vehicle speed depends on deploying the towed antenna and is large enough to pull the towed antenna from the guide tube.

Gemäß einer vorteilhaften Ausführungsform der Erfindung vermögen die Formkörper auf dem Seil zu rotieren, so daß diese beim Schleppen im Heckwasser über das Seil kein Rotationsmoment auf die Schleppantenne aufbringen.According to an advantageous embodiment of the invention, the shaped bodies are able to rotate on the rope, so that they do not apply any rotational torque to the towed antenna when hauling in the stern water over the rope.

Gemäß einer vorteilhaften Ausführungsform der Erfindung weist jeder Formkörper einen Trichter mit in Schlepprichtung weisender Trichteröffnung, sowie eine an dem von der Trichteröffnung abgekehrten Ende angeordnete, über den Trichtermantel vorstehende Endscheibe auf, wobei vorzugsweise der Außendurchmesser der Endscheibe gleich dem Außendurchmesser des Trichters an der Trichteröffnung bemessen ist. Die in Schlepprichtung offene Trichterbauform der Formstücke mit dahinterliegender Endscheibe sorgt in der freien Strömung bei geringer Fahrgeschwindigkeit des Wasserfahrzeugs für einen ausreichend hohen Strömungswiderstand und somit für eine ausreichend hohe Zugkraft am Schleppantennenende.According to an advantageous embodiment of the invention, each shaped body has a funnel with funnel pointing in the direction of the funnel, and arranged at the end facing away from the funnel opening end, over the funnel jacket protruding end plate, wherein preferably the outer diameter of the end plate equal to the outer diameter of the funnel at the funnel opening is. Open in the direction of towing funnel shape pieces with underlying end plate ensures in the free flow at low speed of the watercraft for a sufficiently high flow resistance and thus for a sufficiently high tensile force at the tow antenna end.

Gemäß einer vorteilhaften Ausführungsform der Erfindung weist die Vortriebseinheit ein Spülrohr mit einer Ein- und Austrittsöffnung für die Schleppantenne auf, in dem nahe der Eintrittsöffnung ein Wasserdruck erzeugbar ist. Bei Beginn des Fiervorgangs liegt das Antennen-Endstück in dem Spülrohr ein, wobei seine Formkörper im Spülrohr axial verschieblich geführt und von dem Wasserdruck beaufschlagt sind. Durch diese konstruktive Ergänzung der Vortriebseinheit wird bereits vom Anfang des Fiervorgangs an, noch bevor das Antennen-Endstück teilweise oder ganz in das Heckwasser des Wasserfahrzeugs eingetaucht ist, eine in Ausbringrichtung wirkende Zugkraft auf das Schleppantennenende aufgebracht, da der Außendurchmesser der Formstücke nur geringfügig kleiner ist als der Innendurchmesser des Spülrohrs und somit die Formstücke wie vom Wasserdruck beaufschlagte Kolben wirken. Um den Wasserdruck im Spülrohr aufbauen zu können, ist gemäß einer vorteilhaften Ausführungsform der Erfindung an einem Wassereinlaß des Spülrohrs eine Spülpumpe angeschlossen und die Eintrittsöffnung des Spülrohrs mit einer gegen die schlauchartige Schleppantenne dichtenden, vorzugsweise als Labyrinthdichtung ausgeführten Dichtung verschlossen.According to an advantageous embodiment of the invention, the propulsion unit has a flushing pipe with an inlet and outlet opening for the towed antenna, in which a water pressure can be generated near the inlet opening. At the beginning of the Fiervorgangs the antenna tail is in the flushing pipe, with its moldings are guided axially displaceable in the flushing pipe and acted upon by the water pressure. This constructive completion of the propulsion unit is already from the beginning of Fiervorgangs, even before the antenna tail partially or completely into the rear water of Watercraft is immersed, a force acting in the application direction tensile force applied to the towed antenna end, since the outer diameter of the fittings is only slightly smaller than the inner diameter of the wash pipe and thus the fittings act as acted upon by water pressure piston. In order to be able to build up the water pressure in the flushing pipe, according to an advantageous embodiment of the invention, a flushing pump is connected to a water inlet of the flushing pipe and the inlet opening of the flushing pipe is sealed with a seal sealing against the hose-like towed antenna, preferably as a labyrinth seal.

Gemäß einer vorteilhaften Ausführungsform der Erfindung sind bei jedem Formstück auf dem Trichtermantel im Umfangsrichtung gegeneinander, vorzugsweise um 90°, versetzte Axialstege aufgesetzt, die sich von der Trichteröffnung bis zur Endscheibe erstrecken und deren parallel zur Trichterachse verlaufende, äußere Steglinien einen den Außendurchmesser der Endscheibe entsprechenden radialen Abstand von der Trichterachse haben. Auf die Trichteröffnung ist ein axiale Durchtrittsöffnungen aufweisender Abschlußkegel aufgesetzt. Die Kegelform des Abschlußkegels, die Axialstege und die an ihrem Umfang abgerundete Endscheibe sorgen dafür, daß die Formstücke sich im Spülrohr selbst zentrieren und nicht an toleranzbedingten Absetzten im Spülrohr hängenbleiben. Durch die gewählte Länge der Formstücke ist ein Verkanten im Spülrohr verhindert. Der Abschlußkegel fördert vorteilhaft das Einfädeln des Antennen-Endstücks in das Spülrohr beim Wiedereinholen der Schleppantenne.According to an advantageous embodiment of the invention, each form piece on the funnel jacket in the circumferential direction against each other, preferably offset by 90 °, axial webs extending from the funnel opening to the end plate and extending parallel to the funnel axis, outer web lines corresponding to the outer diameter of the end plate radial distance from the funnel axis. On the funnel opening, an axial passage openings exhibiting end cone is placed. The conical shape of the Abschlußkegels, the axial webs and rounded at its periphery end plate ensure that the fittings center themselves in the purge pipe and not stuck to tolerance settling in the purge pipe. Due to the selected length of the fittings, tilting in the flushing pipe is prevented. The termination cone advantageously promotes the threading of the antenna tail in the flush pipe when retrieving the towed antenna.

Dadurch, daß gemäß einer vorteilhaften Ausführungsform der Erfindung die Formkörper aus einem gut gleitenden Material, z.B. Teflon, hergestellt sind, sind die Reibungsverluste der Formkörper im Spülrohr reduziert, wodurch sich der für das Ausziehen der Schleppantenne nutzbare Zugkraftanteil erhöht.Characterized in that according to an advantageous embodiment of the invention, the moldings are made of a good sliding material, such as Teflon, the friction losses of Shaped body reduced in the purge tube, which increases the useful for pulling the towed antenna tractive force.

Gemäß einer vorteilhaften Ausführungsform der Erfindung weist der in Schlepprichtung letzte Formkörper einen Anschlag, vorzugsweise in Form eines mit der Endscheibe einstückigen, kegelstumpfförmigen Verschlußglieds auf, das zum Verschließen der Austrittsöffnung des Spülrohrs ausgebildet ist. Durch diesen Anschlag wird das Hindurchziehen des Antennen-Endstücks durch das Spülrohr hindurch beim Wiedereinholen der Schleppantenne verhindert. Der Moment des Anschlagens des Verschlußglieds an das Spülrohr kann sensiert und zum Abschalten der Antriebsmotoren nach Wiedereinholen der Schleppantenne verwendet werden.According to an advantageous embodiment of the invention, the last in the direction of towing body has a stop, preferably in the form of a one-piece with the end plate, frusto-conical closure member, which is designed to close the outlet opening of the flushing pipe. This stop prevents the passage of the antenna end piece through the flushing pipe when the towed antenna is being retrieved. The moment of abutment of the closure member to the flushing pipe can be sensed and used to shut down the drive motors after retrieving the towed antenna.

Gemäß einer vorteilhaften Ausführungsform der Erfindung ist das Spülrohr in dem Führungsrohr integriert und darin gegen Federkraft axial begrenzt verschiebbar, so daß das Anschlagen des Anschlags bzw. des Verschlußglieds am Spülrohr abgefedert wird, bevor die Antriebsmotoren abgeschaltet sind.According to an advantageous embodiment of the invention, the flushing pipe is integrated in the guide tube and axially displaceable therein against spring force, so that the abutment of the stopper or the closure member is cushioned on the flushing pipe before the drive motors are switched off.

Die in Fig. 1 im Prinzipschaltbild und in Fig. 6 in perspektivischer Darstellung gezeigte Ausbringvorrichtung für eine schlauchartige Unterwasser-Schleppantenne ist auf einem hier nicht dargestellten Wasserfahrzeug, insbesondere einem U-Boot, installiert. Die Installation erfolgt bei einem U-Boot zwischen dem durchfluteten Außenschiff und dem Druckkörper. Die Schleppantenne 10 besteht in bekannter Weise aus einem Schleppstrang und einen den Schleppstrang an das Wasserfahrzeug anbindenden Zugkabel. Der Schleppstrang umfaßt eine flüssigkeit- oder gelgefüllte Schlauchhülle, in der ein Vielzahl von beabstandeten elektroakustischen Wandlern aufgereiht ist. Zwischen Schleppstrang und Zugkabel ist ein Dämpfungsmodul, ein sog. VIM, angeordnet.The application apparatus for a hose-like underwater towed antenna shown in FIG. 1 in a schematic circuit diagram and in FIG. 6 in a perspective view is installed on a watercraft, not shown here, in particular a submarine. The installation takes place in a submarine between the flooded outer ship and the pressure hull. The towed antenna 10 is in a known manner from a tow line and a tow cable connecting the tow line to the vessel. The tow rope comprises a liquid or gel filled tubular casing in which a plurality of spaced electroacoustic transducers are lined up. Between tow line and pull cable, a damping module, a so-called. VIM, arranged.

Im Nichtgebrauchszustand ist die Schleppantenne 10 auf einer mittels eines Antriebsmotors 11 motorisch antreibbaren Speichertrommel 11 in mehreren Lagen aufgewickelt, wobei zur Unterbringung der recht langen Schleppantenne 10 die Speichertrommel 11 eine wesentliche axiale Länge aufweist. Der Speichertrommel 11 ist ein parallel zur Trommelachse motorisch verfahrbarer Spulwagen 12 mit darauf drehgelagertem Spulrad 13 zugeordnet. Das Spulrad 13 führt die Schleppantenne 11 beim Aufwickeln auf die bzw. beim Abwickeln von der Speichertrommel 11, wobei der Spulwagen 12 eine gesteuerte Hin- und Herbewegung längs der Speichertrommel 11 ausführt. Im Abstand von der Speichertrommel 11 ist in Richtung Heck des Wasserfahrzeugs ein Führungsrad 14 angeordnet, das in einem Gestell 15 drehbar gelagert ist, das wiederum in einem in Fig. 1 schematisch angedeuteten Rahmen oder Podest 16 festgelegt ist. Zwischen Gestell 15 und Podest 16 ist mindestes ein, im dargestellten Ausführungsbeispiel zwei, Kraftmesser 17 angeordnet, der bzw. die eine Änderung der vom Gestell 15 auf das Podest 16 aufgebrachten Auflagekraft mißt bzw. messen. Das Führungsrad 14 ist motorisch antreibbar, wozu mindestens ein Elektromotor 141 vorgesehen ist. Die Schleppantenne 10 läuft von der Speichertrommel 11 über das Spulrad 13 und das Führungsrad 14 und wird durch ein Führungsrohr 18 mit einer Eintrittsöffnung 181 und einer hinter dem Heck des Wasserfahrzeugs im freien Wasser liegenden Austrittsöffnung 182 hindurchgeführt. Das Führungsrad 14 ist unmittelbar an der Eintrittsöffnung 181 des Führungsrohrs 18 so angeordnet, daß der von dem Führungsrad 14 tangential ablaufende Antennenabschnitt koaxial zur Normalen der Eintrittsöffnung 181 ausgerichtet ist, somit die Schleppantenne 10 koaxial in das Führungsrohr 18 einläuft. Beim Fiervorgang greift am Ende der Schleppantenne 10, genauer am Ende eines auch hier angeordneten, mit dem Schleppstrang verbundenen Dämpfungsmodul (VIM), eine Zugkraft FA an, die die Schleppantenne 10 durch das Führungsrohr 18 hindurchzieht. Die Zugkraft FA wird mittels einer später noch beschriebenen Vortriebseinheit 19 erzeugt.When not in use, the towed antenna 10 is wound onto a storage drum 11 which can be driven by a motor 11 in a plurality of layers, the storage drum 11 having a substantial axial length for accommodating the rather long towed antenna 10. The storage drum 11 is associated with a parallel to the drum axis motor-driven winder 12 with rotatably mounted thereon Spulrad 13. The winding wheel 13 guides the towed antenna 11 during winding onto or during unwinding from the storage drum 11, wherein the winding carriage 12 executes a controlled reciprocating movement along the storage drum 11. At a distance from the storage drum 11, a guide wheel 14 is arranged in the direction of the stern of the watercraft, which is rotatably mounted in a frame 15, which in turn is fixed in a frame or pedestal 16 schematically indicated in Fig. 1. Between frame 15 and pedestal 16 is at least one, in the illustrated embodiment two, force meter 17 is arranged, which measures or measure a change of the frame 15 applied to the pedestal 16 bearing force. The guide wheel 14 is driven by a motor, for which purpose at least one electric motor 141 is provided. The towed antenna 10 runs from the storage drum 11 via the winding wheel 13 and the guide wheel 14 and is guided through a guide tube 18 with an inlet opening 181 and an outlet opening 182 located in the open water behind the stern of the watercraft. The Guide wheel 14 is arranged directly at the inlet opening 181 of the guide tube 18 so that the tangentially running of the guide wheel 14 antenna section is aligned coaxially to the normal of the inlet opening 181, thus the towed antenna 10 coaxially enters the guide tube 18. When Fiervorgang engages at the end of the towed antenna 10, more precisely at the end of a arranged here, associated with the towed damping module (VIM), a tensile force F A , which pulls the towed antenna 10 through the guide tube 18. The tensile force F A is generated by means of a propulsion unit 19 which will be described later.

Für den störungs- und hemmungsfreien Ablauf des Fier- oder Ausbringvorgangs der Schleppantenne 10 ist eine Regeleinrichtung 20 vorgesehen, die die Antriebsmotoren 111 und 141 von Speichertrommel 11 und Führungsrad 14 in Anpassung an die vom Kraftmesser 17 sensierte Zugkraft FA so synchronisiert, daß der zwischen Speichertrommel 11 und Führungsrad 14 sich jeweils befindliche Schleppantennenabschnitt im wesentlichen gestreckt, d.h. ohne Durchhang, verläuft. Hierzu werden die Drehwinkelgeschwindigkeiten vT und vF von Speichertrommel 11 und Führungsrad 14 an die Zugkraft FA so angepaßt, daß letztere die jeweils von der Speichertrommel 11 durch deren Motor 111 abgewickelte Länge der Schleppantenne 10 durch das Führungsrohr 18 hindurchzuziehen vermag und die Schleppantenne 10 sich nicht vor dem Führungsrad 14 oder am Führungsrohr 18 "aufstauen" kann. Die am Kraftmesser 17 sensierte Auszugskraft FA dient in der Regeleinrichtung 20 als Führungsgröße für die Einstellung der Drehwinkelgeschwindigkeiten vT und vF von Speichertrommel 11 und Führungsrad 14. Hierzu wird die Führungsgröße FA einem ersten Regler 21 der Regeleinrichtung 20 zugeführt. Diesem Regler 21 sind auch die Ist-Drehwinkelgeschwindigkeiten vFist und vTist von Führungsrad 14 und Speichertrommel 11 zugeführt, die von jeweils am Führungsrad 14 bzw. an der Speichertrommel 11 angeordneten Drehgebern 22 bzw. 23 sensiert werden. Mittels der Führungsgröße FA wird die Soll-Drehwinkelgeschwindigkeit vFsoll des Führungsrads 14 und die Soll-Drehwinkelgeschwindigkeit vTsoll der Speichertrommel 11 ermittelt und über die Sollwertausgänge der Regeleinrichtung 20 in den Antriebsmotoren 111 und 141 von Speichertrommel 11 und Führungsrad 14 eingeregelt. Die Kennlinien für den Regelvorgang sind in Fig. 2 und 3 dargestellt. Steigt die Zugkraft FA an, so wird sowohl der Sollwert für die Drehwinkelgeschwindigkeit vT der Speichertrommel 11 als auch der Sollwert für die Drehwinkelgeschwindigkeit VF des Führungsrads 14 linear angehoben. Gleichzeitig wird - wie dies die Kennlinie in Fig. 4 zeigt - dem Führungsrad 14 ein positiver Schlupf s überlagert, der mit zunehmender Führungsgröße reduziert wird und für die durchhangfreie Streckung des zwischen dem Führungsrad 14 und der Speichertrommel 11 sich jeweils befindlichen Abschnitts der Schleppantenne 10 sorgt.For the disturbance and inhibition-free operation of the Fier- or Ausbringvorgangs the towed antenna 10, a control device 20 is provided which synchronizes the drive motors 111 and 141 of storage drum 11 and guide wheel 14 in adaptation to the sensed by the force meter 17 tensile force F A so that the between Storage drum 11 and guide wheel 14 each located towed antenna section is substantially stretched, ie without sag, runs. For this purpose, the rotational angular velocities V T and V F of storage drum 11 and guide wheel 14 are adapted to the tensile force F A , that the latter is able to pull through each of the storage drum 11 by the motor 111 unwound length of the towed antenna 10 through the guide tube 18 and the towed antenna 10th can not "pile up" in front of the guide wheel 14 or on the guide tube 18. The pull-out force F A sensed on the force gauge 17 serves as a reference variable for setting the rotational angular velocities v T and v F of the storage drum 11 and the guide wheel 14 in the control device 20. For this purpose, the reference variable F A becomes first controller 21 of the control device 20 is supplied. This regulator 21 is also supplied with the actual rotational angular velocities v Fist and v Tist of guide wheel 14 and storage drum 11, which are sensed by rotary encoders 22 and 23 respectively arranged on the guide wheel 14 and on the storage drum 11. By means of the reference variable F A , the desired rotational angular velocity v Fsoll of the guide wheel 14 and the target rotational angular velocity v Tset of the storage drum 11 are determined and adjusted via the setpoint outputs of the control device 20 in the drive motors 111 and 141 of the storage drum 11 and guide wheel 14. The characteristics for the control process are shown in FIGS. 2 and 3. If the tensile force F A increases , then both the desired value for the rotational angular velocity v T of the storage drum 11 and the nominal value for the rotational angular velocity V F of the guide wheel 14 are raised linearly. At the same time - as the characteristic curve in Fig. 4 shows - the guide wheel 14, a positive slip s superimposed, which is reduced with increasing guide size and ensures the sag-free stretching of between the guide wheel 14 and the storage drum 11 each located portion of the towed antenna 10 ,

Mittels eines zweiten Reglers 24 in der Regeleinrichtung 20 wird die Vorschubgeschwindigkeit vS des Spulwagens 12 in Abhängigkeit von der Drehwinkelgeschwindigkeit vT der Speichertrommel 11 geregelt. Dem zweiten Regler 24 ist hierzu die Soll-Drehwinkelgeschwindigkeit vTsoll der Speichertrommel 11 sowie die Ist-Vorschubgeschwindigkeit vSist des Spulwagens 12 zugeführt. Letztere wird mittels eines Drehgebers 25 erfaßt, der die Drehwinkelgeschwindigkeit einer Getriebeabtriebswelle oder der Abtriebswelle des Motors 121 sensiert. Über den entsprechenden Sollwertausgang wird die Soll-Vorschubgeschwindigkeit vSsoll in dem Antriebsmotor 121 eingeregelt. Fig. 5 zeigt die Kennlinien des zweiten Reglers 24, wobei die Kennlinie a gilt, solange die Schleppantenne 10 von der oberen von insgesamt drei Wickellagen abgezogen wird, während die Kennlinie b für die darunterliegenden beiden, also der zweiten und ersten Wickellage gilt. Letztere umfaßt ausschließlich das Zugkabel der Schleppantenne.By means of a second controller 24 in the control device 20, the feed rate v S of the winder 12 in response to the rotational angular velocity v T of the storage drum 11 is controlled. For this purpose, the setpoint rotational speed v Tset of the storage drum 11 as well as the actual feed speed v Sist of the reeling trolley 12 are fed to the second controller 24. The latter is detected by means of a rotary encoder 25, which senses the rotational angular velocity of a transmission output shaft or the output shaft of the motor 121. Via the corresponding setpoint output, the Target feed rate v setpoint in the drive motor 121. Fig. 5 shows the characteristics of the second controller 24, wherein the characteristic a applies as long as the towed antenna 10 is subtracted from the upper of a total of three winding layers, while the characteristic b applies to the underlying two, so the second and first winding layer. The latter includes only the tow cable of the towed antenna.

Die Vortriebseinheit 19 zur Erzeugung der Zugkraft FA am ausbringseitigen Ende der Schleppantenne 10 ist in Fig. 6 und 7 ausschnittweise und in Fig. 8 im Längsschnitt dargestellt. Sie umfaßt ein mit dem Schleppantennenende fest verbundenes Antennen-Endstück 26, sowie ein in das Führungsrohr 18 integriertes Spülrohr 40, in dem das Antennen-Endstück 26 bei eingeholter und auf der Speichertrommel 11 aufgewickelter Schleppantenne 10 einliegt. Wie aus Fig. 8 ersichtlich ist, weist das Antennen-Endstück 26 eine Vielzahl von Formkörpern 27 auf, die voneinander beabstandet auf einem mit der Schleppantenne 10 fest verbundenen Seil 28 axial im wesentlichen unverschieblich angeordnet sind. Die Anordnung ist dabei so getroffen, daß die Formkörper 27 um das Seil 28 rotieren können. Zur Vereinfachung ist im Fig. 8 das Endstück 26 unmittelbar mit der Schleppantenne 10, genauer mit deren VIM, verbunden dargestellt. Aus Gründen eines einfachen Wechsels von Endstück 26 und Typ der Schleppantenne 10 ist das Seil 28 an einem dem Endstück 26 zugehörigen Schlauchglied befestigt, das seinerseits mit dem VIM der Schleppantenne verbunden ist. Das Schlauchglied umfaßt eine flüssigkeits- oder gelgefüllte, elastische Schlauchhülle, die mittels Formstück ausgesteift ist. Ein lose eingezogenes Seil verhindert eine unzulässig große Dehnung der Schlauchhülle.The propulsion unit 19 to generate the tensile force F A on ausbringseitigen end of the towed antenna 10 is shown in Fig. 6 and 7 fragmentary and in Fig. 8 in longitudinal section. It comprises an antenna end piece 26 fixedly connected to the tow antenna end, and a flushing pipe 40 integrated into the guide tube 18, in which the antenna end piece 26 rests when the towed antenna 10 is wound up and wound on the storage drum 11. As is apparent from Fig. 8, the antenna end piece 26 has a plurality of moldings 27, which are spaced apart on a fixedly connected to the towed antenna 10 rope 28 axially arranged substantially immovable. The arrangement is made such that the moldings 27 can rotate about the cable 28. For simplicity, in Fig. 8, the tail 26 is shown directly connected to the towed antenna 10, more specifically to its VIM. For the sake of a simple change of tail 26 and type of towed antenna 10, the cable 28 is attached to a tailpiece 26 associated hose member, which in turn is connected to the VIM of the towed antenna. The tube member comprises a liquid- or gel-filled, elastic tubular casing which is stiffened by means of a molded piece. A loosely pulled-in rope prevents unacceptably high elongation of the tubular casing.

Die aus einem gut gleitfähigen Material, z.B. Teflon, hergestellten Formkörper 27 sind identisch ausgebildet. Jeder Formkörper 27 ist zweiteilig und setzt sich aus einem langgestreckten Trichterteil 29, das in Fig. 9 bis 11 detailliert dargestellt ist, und aus einem Abschlußkegel 30 zusammen, der in Fig. 12 und 13 in Unteransicht und in einem Längsschnitt dargestellt ist. Im Trichterteil 29 ist ein Trichter 31 mit in Schlepprichtung weisender Trichteröffnung 32, sowie eine an dem von der Trichteröffnung 32 abgekehrten Ende des Trichterteils angeordnete Endscheibe 33 ausgebildet, die über den Trichtermantel 311 radial vorsteht. Die Umrißkanten der Endscheibe 33 sind zu beiden Scheibenflächen hin abgerundet. Die Rundungen sind in Fig. 11 mit 331 gekennzeichnet. Der Trichteröffnung 32 ist ein zylindrischer Ringrand 34 vorgelagert, dessen lichter Durchmesser gleich dem Durchmesser der Trichteröffnung 32 und dessen Außendurchmesser gleich dem Außendurchmesser der Endscheibe 33 bemessen ist, der im Ausführungsbeispiel etwa halb so groß ist wie die axiale Länge des Trichterteils 13. Auf den Trichtermanel 311 sind vier in Umfangsrichtung um 90° gegeneinander versetzt angeordnete Axialstege 35 aufgesetzt, die sich jeweils von dem Ringrand 34 bis zur Endscheibe 33 erstrecken. Die äußere Steglinie 351 der Axialstege 35, die parallel zu der Trichterachse verläuft, hat einen radialen Abstand von der Trichterachse, der gleich dem Außenradius der Endscheibe 33 und dem Außenradius des Ringrands 34 ist. In die Endscheibe 33 ist eine zentrale Durchgangsbohrung 36 eingebracht, die im Trichtergrund mündet.Made of a good lubricious material, e.g. Teflon, molded body 27 are formed identically. Each shaped body 27 is in two parts and is composed of an elongated funnel portion 29, which is shown in detail in FIGS. 9 to 11, and a closure cone 30, which is shown in FIGS. 12 and 13 in a bottom view and in a longitudinal section. In funnel part 29, a funnel 31 with a funnel opening 32 pointing in the direction of towing, and an end plate 33 arranged at the end of the funnel part remote from funnel opening 32 are formed which projects radially over funnel jacket 311. The outline edges of the end plate 33 are rounded towards both disc surfaces. The curves are marked 331 in FIG. 11. The funnel opening 32 is preceded by a cylindrical ring edge 34, whose clear diameter is equal to the diameter of the funnel opening 32 and whose outer diameter is equal to the outer diameter of the end plate 33, which in the embodiment about half as large as the axial length of the funnel part 13. On the funnel man 311 four offset in the circumferential direction by 90 ° staggered axial webs 35 are placed, each extending from the ring edge 34 to the end plate 33. The outer web line 351 of the axial webs 35, which is parallel to the funnel axis, has a radial distance from the funnel axis, which is equal to the outer radius of the end plate 33 and the outer radius of the annular rim 34. In the end plate 33, a central through-bore 36 is introduced, which opens in the funnel base.

Der an das Trichterteil 29 angesetzte Abschlußkegel 30 weist drei um 120° Drehwinkel gegeneinander versetzte, axiale Durchgangsöffnungen 37 sowie eine zentrale Durchgangsbohrung 38 auf. Die Durchtrittsöffnungen 37 sind so groß gemacht, daß praktisch nur noch Stege zwischen ihnen verbleiben, die sternförmig angeordnet sind. Im Sternpunkt verläuft die Durchgangsbohrung 38. Von dem der Trichteröffnung 32 zugekehrten Ende des Abschlußkegels 30 steht ein Ringsteg 39 axial vor, dessen Außendurchmesser wenig kleiner als der Innendurchmesser des Ringrands 34 am Trichterteil 29 bemessen ist, so daß der Abschlußkegel 30 mit seinem Ringsteg 29 formschlüssig in den Ringrand 34 des Trichterteils 29 einschiebbar ist. Nach Durchfädeln des Seils 28 durch die Durchgangsöffnungen 37 und 38 werden Trichterteil 29 und Abschlußkegel 30 fest miteinander verbunden, z.B. durch mehrere radial am Umfang versetzte Schraubverbindungen zwischen Ringrand 34 und Ringsteg 39. Die axiale Unverschiebbarkeit der Formkörper 27 auf dem Seil 28 wird beispielsweise durch Knoten im Seil 28 realisiert, wobei sich der Trichtergrund und die Grundfläche des Abschlußkegels 30 jeweils an einem Seilknoten abstützen.The attached to the funnel portion 29 Abschlußkegel 30 has three by 120 ° rotation angle offset from each other, axial through holes 37 and a central through hole 38. The passage openings 37 are made so large that practically only webs remain between them, which are arranged in a star shape. From the funnel opening 32 facing the end of the Abschlußkegels 30 is an annular web 39 axially before, whose outer diameter is less than the inner diameter of the annular rim 34 on the funnel part 29 is dimensioned so that the Abschlußkegel 30 with its annular land 29 positively in the annular edge 34 of the funnel part 29 can be inserted. After threading the cable 28 through the through holes 37 and 38 funnel part 29 and end cone 30 are firmly connected to each other, for example, by a plurality of radially offset on the circumference screw between ring edge 34 and ring land 39. The axial Unverschiebbarkeit the molded body 27 on the rope 28, for example, by nodes realized in the rope 28, wherein the funnel base and the base of the end cone 30 are each supported on a rope node.

Das Spülrohr 40 der Vortriebseinheit 19 mit einer Eintrittsöffnung 401 und einer Austrittsöffnung 402 für die Schleppantenne 10 (Fig. 7 und 8) ist in das Führungsrohr 18 eingezogen und im Führungsrohr 18 gegen die Kraft einer Druckfeder 41 begrenzt axial verschiebbar. Die Austrittsöffnung 402 des Spülrohrs 40 liegt an oder nahe der Austrittsöffnung 182 des Führungsrohrs 18. Auf die Eintrittsöffnung 401 des Spülrohr 40 ist eine Y-Rohrverzweigung 42 aufgesetzt und mittels einer Schraubhülse 43 mit dem Spülrohr 40 und dem Führungsrohr 18 fest verbunden. In den mit dem Spülrohr 40 koaxialen Rohrstutzen 421 der Y-Rohrverzweigung 42 ist die Schleppantenne 10 eingeführt, wobei eine Labyrinthdichtung 44 die Rohrinnenwand gegenüber der Schlauchhülle der Schleppantenne 10 weitgehend druckdicht abdichtet. Der unter einem spitzen Winkel zum Rohrstutzen 421 verlaufende andere Rohrstutzen 422 der Y-Rohrverzweigung 42 bildet einen Wassereinlaß 45 und ist an einer hier nur schematisch angedeuteten Spülpumpe 47 angeschlossen, die einen Wasserdruck im Spülrohr 40 aufzubauen vermag.The flushing pipe 40 of the propulsion unit 19 with an inlet opening 401 and an outlet opening 402 for the towed antenna 10 (FIGS. 7 and 8) is retracted into the guide tube 18 and limited axially displaceable in the guide tube 18 against the force of a compression spring 41. The outlet opening 402 of the flushing pipe 40 is located at or near the outlet opening 182 of the guide tube 18. A Y-branch 42 is placed on the inlet opening 401 of the flushing pipe 40 and firmly connected by means of a threaded sleeve 43 with the flushing pipe 40 and the guide tube 18. In the coaxial with the flush pipe 40 pipe socket 421 of the Y-branch pipe 42, the towed antenna 10 is inserted, wherein a labyrinth seal 44 seals the pipe inner wall against the tubular casing of the towed antenna 10 largely pressure-tight. At an acute angle to the Pipe stub 421 extending other pipe socket 422 of the Y-branch pipe 42 forms a water inlet 45 and is connected to a here indicated only schematically rinsing pump 47, which is able to build a water pressure in the purge pipe 40.

Bei vollständig auf die Speichertrommel 11 aufgewickelter Schleppantenne 10 ist das am Ende der Schleppantenne 10 mittels des Seils 28 befestigte Antennen-Endstück 26 mit seinen Formkörpern 27 vollständig in das Spülrohr 40 eingezogen. Das Ende der Schleppantenne 10, bzw. das mit der Schleppantenne 10 verbundene Schlauchglied des Antennen-Endstücks 26, ragt in die Eintrittsöffnung 401 des Spülrohrs 40 hinein. Am Eintritt der Schleppantenne 10 bzw. des Schlauchglieds in den Rohrstutzen 421 der Y-Rohrverzweigung 42 dichtet eine Labyrinthdichtung 44 die Rohrinnenwand gegen die schlauchförmige Schleppantenne 10 bzw. das Schlauchglied ab. Die Formkörper 27, deren Außendurchmesser nur wenig kleiner ist als der lichte Durchmesser des Spülrohrs 40, sind mittels der Endscheibe 33, des Ringrands 34 und der Axialstege 35 im Spülrohr 40 geführt und besitzen aufgrund des für ihre Herstellung verwendeten Materials eine gute Gleitfähigkeit. Wird nunmehr mit Beginn des Ausbringvorgangs oder Fierens der Schleppantenne 10 ein Wasserdruck von z.B. 2 - 3 bar im Spülrohr 40 erzeugt, so wirken die Formkörper 27 wie Kolben, die durch den Wasserdruck in Richtung Austrittsöffnung 402 des Spülrohrs 40 verschoben werden und dadurch über das Seil 28 die Zugkraft FA an der Schleppantenne 10 erzeugen. Nach Erreichen der Austrittsöffnung 402 des Spülrohrs 40 treten die Formkörper 27 sukzessive aus dem Spülrohr 40 aus und tauchen in das Heckwasser des Wasserfahrzeugs ein. Das voll aus dem Spülrohr 40 ausgezogene Antennen-Endstück 26 erzeugt weiterhin, nunmehr aufgrund seines dem Wasser entgegengesetzten Strömungswiderstandes, die Zugkraft FA, die durch seinen Strömungswiderstand und die Schleppgeschwindigkeit des Wasserfahrzeugs bestimmt ist. Diese Zugkraft stellt weiterhin sicher, daß die Schleppantenne 10 störungsfrei durch das Spülrohr 40 hindurch ausgezogen wird, bis sie in ihrer vollen Länge im Wasser ausliegt und an ihrem vorderen Ende über das ebenfalls ausgezogene Zugkabel mit der auf dem Wasserfahrzeug festgelegten Speichertrommel 11 verbunden bleibt.When fully wound on the storage drum 11 towed antenna 10 is attached to the end of the towed antenna 10 by means of the cable 28 antenna end piece 26 with its moldings 27 completely drawn into the flushing pipe 40. The end of the towed antenna 10, or the hose member of the antenna end piece 26 connected to the towed antenna 10, protrudes into the inlet opening 401 of the flushing pipe 40. At the entrance of the towed antenna 10 or the hose member into the pipe socket 421 of the Y-branch pipe 42, a labyrinth seal 44 seals the pipe inner wall against the tubular towed antenna 10 or the hose member. The moldings 27, the outer diameter of which is only slightly smaller than the clear diameter of the flushing pipe 40, are guided in the flushing pipe 40 by means of the end disk 33, the annular rim 34 and the axial webs 35 and have a good lubricity due to the material used for their production. If a water pressure of, for example, 2 to 3 bar is now generated in the flushing pipe 40 at the beginning of the discharge process or when the towed antenna 10 is being started, the shaped bodies 27 act like pistons which are displaced by the water pressure in the direction of the outlet opening 402 of the flushing pipe 40 and thereby over the cable 28 generate the tensile force F A on the towed antenna 10. After reaching the outlet opening 402 of the flushing pipe 40, the molded bodies 27 emerge successively from the flushing pipe 40 and dip into the stern water of the watercraft. The fully drawn out of the flushing pipe 40 antenna tail 26 continues to generate, now due to its water resistance opposed to the flow, the tensile force F A , which is determined by its flow resistance and the towing speed of the vessel. This traction further ensures that the towed antenna 10 is smoothly pulled through the purge pipe 40 therethrough until it lies in its full length in the water and remains connected at its front end on the likewise extended traction cable with the storage drum 11 fixed on the vessel.

Beim Wiedereinholen der Schleppantenne 10 und Aufwickeln auf die Speichertrommel 11 lassen sich die Formkörper 27 des Antennen-Endstücks 26 aufgrund des dem Trichterteil 29 vorgesetzten Abschlußkegels 30 mühelos in das Spülrohr 40 einführen. Am letzten Formkörper 27 des Antennen-Endstücks 26 ist ein kegelstumpfförmiges Verschlußglied 46 angeordnet, das zum Verschließen der Austrittsöffnung 402 des Spülrohrs 40 ausgebildet ist und einen Anschlag zur Begrenzung der Einzugsbewegung der Schleppantenne 10 bildet. Das Verschlußglied 46 ist an der Endscheibe 33 befestigt. Alternativ kann es am Seil 28 befestigt oder mit der Endscheibe 33 einstückig ausgebildet sein. Ist das Antennen-Endstück 26 vollständig eingezogen, so schlägt das Verschlußglied 46 am Spülrohr 40 an, und das Spülrohr 40 wird gegen die Kraft der Druckfeder 41 im Führungsrohr 18 verschoben. Die Axialverschiebung des Spülrohrs 40 oder das Anwachsen der Federkraft der Druckfeder 41 wird sensiert und daraus ein Abschaltsignal für die Motoren 111, 121 und 141 von Speichertrommel 11, Spulwagen 12 und Führungsrad 14 generiert.When retrieving the towed antenna 10 and winding on the storage drum 11, the shaped body 27 of the antenna end piece 26 can be easily inserted into the flushing pipe 40 due to the funnel part 29 superior termination cone 30. On the last shaped body 27 of the antenna end piece 26, a frusto-conical closure member 46 is arranged, which is designed to close the outlet opening 402 of the wash tube 40 and forms a stop for limiting the retraction movement of the towed antenna 10. The closure member 46 is attached to the end plate 33. Alternatively, it may be attached to the cable 28 or integrally formed with the end plate 33. If the antenna end piece 26 is completely retracted, then the closure member 46 abuts the flushing pipe 40, and the flushing pipe 40 is displaced against the force of the compression spring 41 in the guide tube 18. The axial displacement of the flushing pipe 40 or the increase in the spring force of the compression spring 41 is sensed and used to generate a switch-off signal for the motors 111, 121 and 141 of the storage drum 11, winding carriage 12 and guide wheel 14.
