Description

Die Erfindung betrifft eine Aufklärungssonde, die als abwerfbarer Lastkörper von einem Trägergeschoß in ein Zielgebiet verbringbar ist und nach dem Aufsetzen auf dem Erdboden zielrelevante Informationen detektiert.The invention relates to a reconnaissance probe, which can be brought as a thrown off load body from a carrier projectile into a target area and detects target-relevant information after placement on the ground.

Eine derartige Sonde ist beispielsweise aus der DE 199 06 970 C2 bekannt. Zur Ermittlung der zielrelevanten Informationen umfaßt diese bekannte Sonde unter anderem mehrere gleichartige akustische Sensoren, die an den äußeren Enden von Sensorträgern angeordnet sind. Dabei sind die Sensorträger an den außenseitigen Enden, paddelförmig ausgebildeter Stützbeine von einer eingeklappten in eine ausgeklappte Stellung schwenkbar befestigt, welche die Sonde nach dem Aufsetzen auf den Erdboden abstützen. Als nachteilig hat es sich bei dieser bekannten Aufklärungssonde unter anderem erwiesen, daß die akustischen Sensoren bei ihrer bestimmungsgemäßen Verwendung einen nur relativ geringen Abstand zum Erdboden aufweisen, so daß Ziele häufig nicht oder nicht rechtzeitig detektiert werden.Such a probe is for example from the DE 199 06 970 C2 known. To determine the information relevant to the target, this known probe comprises, inter alia, a plurality of identical acoustic sensors which are arranged at the outer ends of sensor carriers. The sensor carrier at the outside ends, paddle-shaped support legs are pivotally mounted from a folded into an unfolded position, which support the probe after placing it on the ground. It has proved to be disadvantageous in this known reconnaissance probe, inter alia, that the acoustic sensors have only a relatively small distance to the ground when used as intended, so that targets are often not or not detected in time.

Weitere gattungsgemäße Sonden sind aus den US 5 339 281 A und EP 1 494 189 A2 bekannt.Other generic probes are from the US 5 339 281 A and EP 1 494 189 A2 known.

Der Erfindung liegt die Aufgabe zugrunde, eine Aufklärungssonde mit mehreren gleichartigen Sensoren, insbesondere akustischen Sensoren, anzugeben, die bei ihrer bestimmungsgemäßen Verwendung sowohl einen möglichst großen Abstand zum Erdboden als auch einen möglichst großen Abstand voneinander aufweisen.The invention has for its object to provide a reconnaissance probe with a plurality of similar sensors, in particular acoustic sensors, which have in their intended use both the greatest possible distance from the ground and the greatest possible distance from each other.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

Die Erfindung beruht im wesentlichen auf dem Gedanken, die aufklappbaren Sensorträger nicht an den Stützbeinen der Aufklärungssonde schwenkbar anzuordnen, sondern im Bereich der dem Erdboden abgewandten Oberseite des Gehäuses der Auflclärungssonde, wobei die Sensorträger aus mehreren rohrförmigen Tragarmen bestehen, die teleskopartig auseinanderschiebbar ausgebildet sind. Dabei umfaßt die Aufklärungssonde Mittel, die sicherstellen, daß die Tragarme des jeweiligen Sensorträgers beispielsweise mittels einer Druckfeder erst auseinandergeschoben werden, wenn die Sensorträger sich in ihrer ausgeklappten Stellung befinden oder wenn der jeweils in die ausgeklappte Stellung sich bewegende Sensorträger bei seiner Entfaltung nicht mehr bei dieser Schwenkbewegung (z.B. durch den Erdboden) behindert werden kann.The invention is based essentially on the idea of not pivotally arranging the hinged sensor carrier on the support legs of the reconnaissance probe, but in the area the upper side facing away from the ground of the housing of the Auflclärungssonde, wherein the sensor carrier consist of a plurality of tubular support arms which are formed telescopically auseinanderschiebbar. In this case, the reconnaissance probe comprises means which ensure that the support arms of the respective sensor carrier are first pushed apart, for example by means of a compression spring, when the sensor carrier are in their unfolded position or if the respectively in the unfolded position moving sensor carrier in its unfolding no longer in this Pivoting movement (eg through the ground) can be hindered.

Vorzugsweise ist der erste Tragarm mit dem größten Durchmesser im auseinandergeschobenen Zustand des jeweiligen Sensorträgers auf der von dem Gehäuse abgewandten Seite des Sensorträgers angeordnet und weist auf seiner dem Gehäuse zugewandten Seite mindestens ein Führungselement auf, das in der eingeklappten Stellung des Sensorträgers in eine Führungsnut einer fest mit dem Gehäuse verbundenen Führungsplatte eingreift, derart, daß dieser Tragarm bei der Schwenkbewegung des Sensorträgers in seine ausgeklappte Stellung zunächst schwenkbar mit dem Gehäuse verbunden bleibt und daß erst nach Erreichen eines vorgegebenen Öffnungswinkels der Führungsbolzen von der Führungsnut freigegeben wird, so daß der Sensorträger erst anschließend, z.B. durch die Druckfeder, auseinandergeschoben werden kann.Preferably, the first support arm is arranged with the largest diameter in the telescoped state of the respective sensor carrier on the side facing away from the housing side of the sensor carrier and has on its side facing the housing at least one guide element which in the folded position of the sensor carrier in a guide groove of a fixed engaged with the housing guide plate engages, such that this support arm initially pivotally connected to the housing during the pivoting movement of the sensor carrier in its unfolded position and that is released only after reaching a predetermined opening angle of the guide pin of the guide, so that the sensor carrier only afterwards , eg by the compression spring, can be pushed apart.

Um eine einfache und schnelle Montage der erfindungsgemäßen Auflclärungssonde zu erreichen, hat es sich als zweckmäßig erwiesen, daß der jeweilige Sensorträger einschließlich des den Sensorträger verschwenkenden Mechanismus eine vormontierbare modulare Einheit bildet, die ein mit dem Gehäuse der Auflclärungssonde verbindbares Gestell umfaßt, in dem der Sensorträger mittels einer Feder um eine Drehachse schwenkbar angeordnet ist, wobei zwei Seitenplatten des Gestelles die Führungsplatten mit den Führungsnuten bilden, in welche die Führungselemente des ersten Tragarmes eingreifen.In order to achieve a simple and rapid assembly of the invention Auflclärungssonde, it has proved expedient that the respective sensor carrier including the sensor carrier pivoting mechanism forms a preassemblable modular unit comprising a connectable to the housing of Auflclärungssonde frame in which the sensor carrier is arranged pivotably about an axis of rotation by means of a spring, wherein two side plates of the frame form the guide plates with the guide grooves, in which engage the guide elements of the first support arm.

In den Fig.1-3 ist mit 1 eine Aufklärungssonde bezeichnet, die beispielsweise von einem Trägergeschoß über ein Zielgebiet verbracht, dort abgeworfen wurde und dann mittels eines nicht dargestellten Fallschirmes zur Erde gelangt.In the Fig.1-3 is denoted by 1 a reconnaissance probe, for example, spent by a carrier projectile over a target area, was dropped there and then reaches the earth by means of a parachute, not shown.

Nach dem Auftreffen auf den Erdboden werden vier paddelförmig ausgebildete, gewölbte Stützbeine 2, die vorher einen Außenmantel bildeten, aufgeklappt, um die Aufklärungssonde 1 aufzurichten und anschließend einen sicheren Stand der Aufklärungssonde 1 auf dem Erdboden zu gewährleisten (Fig.2).After hitting the ground, four paddle-shaped arched support legs 2, which previously formed an outer sheath, are unfolded in order to erect the reconnaissance probe 1 and then to ensure a secure state of the reconnaissance probe 1 on the ground ( Fig.2 ).

Nach dem Aufklappen der Stützbeine 2 werden fünf gleichmäßig über den äußeren Umfang eines Gehäuses 3 verteilt angeordnete Sensorträger 4 freigegeben, die jeweils um eine im oberen Bereich 5 des Gehäuses 3 befindliche Drehachse 6 von einer Ruhestellung, bei der sie etwa parallel zur Längsachse 100 des Gehäuses 3 angeordnet sind, in eine ausgeklappte Stellung, bei der sie im wesentlichen radial zur Längsachse 100 des Gehäuses 3 nach außen geklappt sind, schwenkbar an dem Gehäuse 3 (oder einem Gehäusedeckel) befestigt sind (Fig.4). Die Sensorträger 4 sind jeweils durch eine Doppelschenkelfeder 7 vorgespannt und werden in ihrer Ruhestellung durch ein lösbares Fixierelement 101, welches in Fig.2 schematisch als Seil angedeutet ist, gehalten.After unfolding the support legs 2, five evenly distributed over the outer circumference of a housing 3 arranged sensor carrier 4 are released, each about a located in the upper region 5 of the housing 3 axis of rotation 6 from a rest position at they are arranged approximately parallel to the longitudinal axis 100 of the housing 3, in an unfolded position, in which they are folded outward substantially radially to the longitudinal axis 100 of the housing 3, are pivotally mounted on the housing 3 (or a housing cover) ( Figure 4 ). The sensor carriers 4 are each biased by a double leg spring 7 and are in their rest position by a releasable fixing element 101, which in Fig.2 schematically indicated as a rope held.

Die Sensorträger 4 umfassen bei dem dargestellten Ausführungsbeispiel jeweils drei ineinandergeschobene rohrförmige Tragarme 8-10 (Fig.3), die z.B. durch eine Druckfeder teleskopartig auseinanderschiebbar sind. Dabei weist der erste Tragarm 8 des jeweiligen Sensorträgers 4 den größten Durchmesser auf und ist im auseinandergeschobenen Zustand des Sensorträgers 4 auf der von dem Gehäuse 3 abgewandten Seite des Sensorträgers 4 angeordnet. An diesem Tragarm 8 ist ein akustischer Sensor 12 befestigt.In the exemplary embodiment illustrated, the sensor carriers 4 each have three telescoping tubular support arms 8 - 10 (FIG. Figure 3 ), which are telescopically pushed apart, for example by a compression spring. In this case, the first support arm 8 of the respective sensor carrier 4 has the largest diameter and is arranged in the pushed-apart state of the sensor carrier 4 on the side facing away from the housing 3 side of the sensor carrier 4. At this support arm 8, an acoustic sensor 12 is attached.

Außerdem weist der Tragarm 8 auf seiner dem Gehäuse 3 zugewandten Seite mindestens einen Führungsbolzen 13 auf, der in der eingeklappten Stellung des Sensorträgers 4 in eine Führungsnut 14 einer an dem Gehäuse 3 angeordneten Führungsplatte 15 eingreift (Fig.4).In addition, the support arm 8 has on its side facing the housing 3 at least one guide pin 13, which engages in the folded position of the sensor carrier 4 in a guide groove 14 of a arranged on the housing 3 guide plate 15 ( Figure 4 ).

Nach Lösen des Arretierelementes (z.B. durch ein nicht dargestelltes Schneidwerkzeug) werden zunächst die Sensorträger 4 durch die Doppelschenkelfedern 7 in Richtung auf ihre ausgeklappte Stellung verschwenkt (Fig.2). Dabei wird der Führungsbolzen 13 entlang der Führungsnut 14 der Führungsplatte 15 geführt, so daß der erste Tragarm 8 bei der Schwenkbewegung des Sensorträgers 4 zunächst mit dem Gehäuse 3 verbunden bleibt. Erst nach Erreichen eines vorgegebenen Öffnungswinkels zwischen der Achse des jeweiligen Sensorträgers 4 und der Längsachse 100 des Gehäuses 3 von z.B. 90° wird der Führungsbolzen 13 von der Führungsnut 14 freigegeben, und der Sensorträger 4 kann sich vollständig axial entfalten und wird in seine durch einen Endanschlag 16 vorgegebene Endlage bei einem Öffnungswinkel von z.B. 105° gedrückt (Fig.3).After releasing the locking element (for example, by a cutting tool, not shown), the sensor carrier 4 are first pivoted by the double torsion springs 7 in the direction of its unfolded position ( Fig.2 ). In this case, the guide pin 13 is guided along the guide groove 14 of the guide plate 15, so that the first support arm 8 is initially connected to the housing 3 during the pivoting movement of the sensor carrier 4. Only after reaching a predetermined opening angle between the axis of the respective sensor carrier 4 and the longitudinal axis 100 of the housing 3 of eg 90 °, the guide pin 13 is released from the guide groove 14, and the sensor carrier 4 can fully develop axially and is in its by an end stop 16 predetermined end position at an opening angle of eg 105 ° pressed ( Figure 3 ).

Durch einen entsprechenden Verlauf der Führungsnut 14 kann auf einfache Weise erreicht werden, daß auch bereits vor der Freigabe des Führungsbolzens 13 ein leichtes Auseinanderschieben der Tragarme 8-10 des Sensorträgers 4 möglich ist, wenn der jeweilige Abstand zwischen der Drehachse 6 des Sensorträgers 4 und der Führungsnut 14 sich entsprechend vergrößert, wie dieses in Fig.4 angedeutet ist.By a corresponding course of the guide groove 14 can be achieved in a simple manner that even before the release of the guide pin 13, a slight sliding apart of the support arms 8-10 of the sensor carrier 4 is possible if the respective distance between the axis of rotation 6 of the sensor carrier 4 and the guide groove 14 is increased accordingly, as this in Figure 4 is indicated.

Um eine schnelle Montage der erfindungsgemäßen Aufklärungssonde 1 vorzunehmen, hat es sich als vorteilhaft erwiesen, wenn der jeweilige Sensorträger 4 einschließlich des den Sensorträger 4 verschwenkenden Mechanismus eine vormontierbare modulare Einheit bildet, die mit dem Gehäuse 3 der Aufklärungssonde 1 dann anschließend verbindbar ist.In order to carry out a quick mounting of the reconnaissance probe 1 according to the invention, it has proved to be advantageous if the respective sensor carrier 4, including the mechanism pivoting the sensor carrier 4, forms a preassemblable modular unit which can then be subsequently connected to the housing 3 of the reconnaissance probe 1.

Eine derartige mit 20 bezeichnete modulare Einheit ist in Fig.5 dargestellt. Dabei sind mit dem vorhergehenden Ausführungsbeispiel funktionsgleiche Elemente mit gleichen Bezugszeichen versehen.Such a modular unit designated 20 is shown in FIG Figure 5 shown. In this case, functionally identical elements are provided with the same reference numerals with the preceding embodiment.

Die modulare Einheit 20 setzt sich im wesentlichen aus einem mit dem Gehäuse 3 der Aufklärungssonde 1 verbindbaren Gestell 21 zusammen, in dem der wiederum aus drei Tragarmen 8-10 bestehende Sensorträger 4 mittels einer Doppelschenkelfeder 7 um eine Drehachse 6 schwenkbar angeordnet ist. Zwei Seitenplatten 22, 23 des Gestelles 21 bilden dabei die Führungsplatten mit den Führungsnuten 14, in welche die Führungsbolzen 13 des ersten Tragarmes 8 eingreift.The modular unit 20 consists essentially of a connectable to the housing 3 of the reconnaissance probe 1 frame 21, in which the turn of three support arms 8-10 existing sensor carrier 4 is pivotally mounted about a rotation axis 6 by means of a double leg spring 7. Two side plates 22, 23 of the frame 21 thereby form the guide plates with the guide grooves 14, in which the guide pin 13 of the first support arm 8 engages.

Außerdem ist an dem Tragarm 8 eine Halteeinrichtung 24 für den nicht dargestellten akustischen Sensor vorgesehen.In addition, a holding device 24 for the acoustic sensor, not shown, is provided on the support arm 8.

In den Fig.6 und 7 sind der Sensorträger 4 in auseinandergeschobener Stellung dargestellt, wobei mit 24' die sich im Inneren der Tragarme 8-10 befindliche Druckfeder bezeichnet ist, welche in dem Tragarm 10 durch ein Führungsrohr 25 geführt wird.In the Fig.6 and 7 the sensor carrier 4 are shown in a pushed-apart position, wherein 24 'which is located inside the support arms 8-10 located compression spring, which is guided in the support arm 10 by a guide tube 25.

Die Erfindung ist selbstverständlich nicht auf die vorstehend beschriebenen Ausführungsbeispiele beschränkt. So können statt der Federn beispielsweise auch Pyroelemente (Gasgeneratoren) verwendet werden. Die Sensorträger wie die Tragarme des jeweiligen Sensorträgers brauchen in diesem Fall in ihrer Ruhestellung nicht vorgespannt zu werden. Mit dem Auslösen des Gasdruckes wird zuerst ein Verschwenken der Sensorträger und anschließend eine axiale Verschiebung der Tragarme bewirkt.The invention is of course not limited to the embodiments described above. Thus, for example, pyroelements (gas generators) can also be used instead of the springs. The sensor carrier as the support arms of the respective sensor carrier need not be biased in this case in its rest position. With the triggering of the gas pressure, a pivoting of the sensor carrier and then an axial displacement of the support arms is effected first.

Außerdem kann eine Arretiereinrichtung an dem Gehäuse vorgesehen sein, welche den jeweiligen Sensorträger nach Erreichen des Endanschlages in seiner Lage fixiert, so daß der Sensorträger, z.B. bei einem Federbruch, nicht in Richtung auf seine eingeklappte Stellung zurückbewegt wird.In addition, a locking device may be provided on the housing, which fixes the respective sensor carrier after reaching the end stop in its position, so that the sensor carrier, e.g. is moved back in a spring break, not in the direction of its retracted position.

Ferner muß die Fixierung der durch Federn vorgespannten Sensorträger in ihre jeweilige Ruhelage nicht zwingend durch ein Seil erfolgen, sondern es können hierzu auch lösbare mechanische Rastverbindungen oder elektromechanische Verbindungen vorgesehen werden.Furthermore, the fixation of the biased by springs sensor carrier in their respective rest position does not necessarily have to be done by a rope, but it can also be provided for releasable mechanical snap-in connections or electromechanical connections.

Außerdem können die Sensorträger auch nur zwei oder auch mehr als drei teleskopartig auseinanderschiebbare Tragarme umfassen.In addition, the sensor carrier can also comprise only two or even more than three telescopically push-out support arms.

  1. Reconnaissance sonde, which can be deployed as a load body which can be launched from a carrier projectile into a target region and detects target-relevant information after being placed on the ground, having the following features:
    a) the reconnaissance probe (1) comprises a housing (3) and a plurality of tubular sensor mounts (4) which are arranged distributed over the circumference of the housing (3) and can each be pivoted at their first end (17) about a rotation axis (6), which is arranged in the upper area (5) of the housing (3), from a rest position in which they are arranged approximately parallel to the longitudinal axis (100) of the housing (3) to a folded-out position, in which they are folded outwards essentially radially with respect to the longitudinal axis (100) of the housing (3), and which are each fitted at their opposite second end (18) with at least one sensor (12);
    b) the sensor mounts (4) are held in their rest position by a detachable fixing element (101) and can each be pivoted to their folded-out position by means of at least one first element (7) after the locking element has been released;
    c) the sensor mounts (4) each comprise at least two tubular mounting arms (8-10), which are pushed into one another and can be pushed out of one another, telescopically, by means of at least one second element (24');
    d) the reconnaissance sonde (1) has means (13-15; 22, 23) which ensure that the mounting arms (8-10) of the respective sensor mount (4) are not pushed out of one another by the second element (24') until the sensor mounts (4) are in their folded-out position or until the sensor mount (4) which is in each case being moved to the folded-out position can no longer be impeded in this pivoting movement during its unfolding by elements which project into the pivoting path.
  2. Reconnaissance sonde according to Claim 1, characterized in that the sensor mounts (4) each comprise three mounting arms (8-10) which can be pushed out of one another telescopically.
  3. Reconnaissance sonde according to Claim 1 or 2, characterized in that the first mounting arm (8) of the respective sensor mount (4) which has the largest diameter when the sensor mount (4) is in the pushed-out state is arranged on that side of the sensor mount (4) which faces away from the housing (3).
  4. Reconnaissance sonde according to Claim 3, characterized in that the first mounting arm (8) of the respective sensor mount (4) has at least one guide element (13) at its first end (17) which guide element (13) engages, when the sensor mount (4) is in the rest position, in a guide groove (14) in a guide plate (15) which is arranged on the housing (3), such that the first mounting arm (8) remains connected to the housing (3), initially such that it can pivot, during the pivoting movement of the sensor mount (4) to its folded-out position, and in that the guide element (13) is not released from the guide groove (14) until a predetermined opening angle has been reached, such that the sensor mount (4) can be unfolded completely on the basis of the second element (24').
  5. Reconnaissance sonde according to one of Claims 1 to 4, characterized in that the first element (7) is a spring, preferably a spring with two limbs, which prestresses the respective sensor mount (4) in its rest position.
  6. Reconnaissance sonde according to one of Claims 1 to 5, characterized in that the second element (24') is a compression spring.
  7. Reconnaissance sonde according to one of Claims 1 to 4, characterized in that the first and the second element (7, 24') comprise a gas generator which is designed such that, after it is initiated, it first of all pivots the sensor mounts (4) to their folded-out position and then pushes the mounting arms (8-10) of the respective sensor mount (4) out of one another.
  8. Reconnaissance sonde according to one of Claims 1 to 7, characterized in that the detachable fixing element (101) for holding the sensor mounts (4) in their rest position is a cable which can be cut by means of a cutting tool.
  9. Reconnaissance sonde according to one of Claims 1 to 8, characterized in that the sensor mount (4) including the mechanism which pivots the sensor mount (4) forms a modular unit (20) which can be preassembled and comprises a frame (21) which can be connected to the housing (3) of the reconnaissance sonde (1) and in which the sensor mount (4) is arranged such that it can be pivoted about a rotation axis (6) by means of a spring (7) wherein two side plates (22, 23) of the frame (21) form the guide plates with the guide grooves (14) in which the guide elements (13) of the first mounting arm (8) engage.
