Description

Die Erfindung bezieht sich auf einen Tandemgefechtskopf mit einem Sekundärgeschoß wie aus DE-C-3 544 528 bekannt (siehe den Oberbegriff des Anspruchs 1)The invention relates to a tandem warhead with a secondary floor as known from DE-C-3 544 528 (see the preamble of Claim 1)

Bei einem Tandemgefechtskopf mit einem Sekundärgeschoß entsprechend der US-A1-4,803,928 ist eine kopfseitige Hohlladung über abscherbare Schrauben in einer Rohrhülse gehalten, wobei diese Rohrhülse mit einem Abschußrohr für ein abschießbares Sekundärgeschoß verschraubt ist. Das Sekundärgeschoß ist bodenseitig mit einer Treibladungshülse abscherbar verstiftet. Ein spezieller Schwadenschutz zum Schutz der Sekundärladung ist nicht vorgesehen. Die Ursache dafür liegt darin, daß die Anzündung der Hohlladung bzw. Bohrladung durch das, sich in Bewegung befindende Sekundärgeschoß eingeleitet wird. Und außerdem das Sekundärgeschoß im Bereich seines Zünders eine sehr große Wanddicke aufweist.In a tandem warhead with a secondary floor according to US-A1-4,803,928 is a hollow charge at the head using shearable screws in one Tube sleeve held, this tube sleeve with a launch tube for a shootable Secondary floor is screwed. The secondary floor is on the floor side pinned with a propellant charge shearable. A special steam protection to protect the secondary charge is not provided. The cause of that is that the ignition of the shaped charge or drilling charge by the, in Moving secondary floor is initiated. And also the secondary floor has a very large wall thickness in the area of its detonator.

Anders sieht es bei einem Gefechtskopf nach der FR-A1 1.002.092 aus. Bei dem in Figur 1 dargestellten Geschoß ist eine kopfseitige Hohlladung durch einen Schwadenschutz gegenüber einem nachfolgenden Wuchtgeschoß getrennt. Der Schwadenschutz ist als etwa kalibergroße Scheibe ausgebildet und sitzt auf der Geschoßogive des Wuchtgeschosses auf. Damit soll die Ogive des Wuchtgeschosses geschützt werden, während die Hohlladung einen Durchschußkanal im Ziel erzeugt. Der Werkstoff des Schwadenschutzes ist nicht angegeben.The situation is different for a warhead according to FR-A1 1.002.092. At the in Figure 1 shown floor is a hollow charge on the head side by a vapor protection separated from a subsequent balancing projectile. The steam protection is designed as an approximately caliber-sized disc and sits on the floor arch of the balancing bullet. This is to protect the ogive of the balancing bullet while the shaped charge creates a bullet channel in the target. The material of the steam protection is not specified.

Ein kegeliger, Detonationsfragmente ablenkender Schwadenschutz ist aus der DE-C-3 544 528 bekannt. Dieser deckt bei einem Tandemladungssystem eine Führungsrohrmündung für eine Nachschußladung ab. Zwischen dem Schwadenschutz und der Nachschußladung ist ein Ringspalt vorgesehen. Dadurch wird zwar weitgehend ein Eindringen von reibungserhöhenden Partikeln erreicht, jedoch nicht verhindert, daß Sprengstoffschwaden zwischen Führungsrohr und Nachschußladung gelangen. A tapered vapor protection deflecting fragments of detonation is from the DE-C-3 544 528 known. In a tandem charging system, this covers a guide tube mouth for a margin load. Between the steam protection and an annular gap is provided for the additional charge. This does largely penetration of friction-increasing particles is achieved, but not prevents explosive swaths between the guide tube and the additional charge reach.

Der Erfindung liegt die Aufgabe zugrunde, eine funktionssichere Anordnung eines Sekundärgeschosses in einem Tandemgefechtskopf vorzuschlagen. Hierbei ist das Sekundärgeschoß als Splittergranate mit Zünder ausgebildet. Dadurch besteht die Gefahr, daß Sprengstoffschwaden die Rückseite des Sekundärgeschosses aufbrechen und zu einer irreversiblen Beschädigung des Sekundärgeschosses führen. The invention has for its object a reliable arrangement of a Propose secondary floor in a tandem warhead. Here is that Secondary storey designed as a frag grenade with detonator. This means that Danger of explosive swaths breaking open the back of the secondary floor and lead to irreversible damage to the secondary floor.

Die Erfindung löst diese Aufgabe entsprechend den kennzeichnenden Merkmalen des Anspruches 1.The invention solves this problem according to the characterizing features of claim 1.

Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments of the invention can be found in the subclaims.

Das Sekundärgeschoß ist über eine Gewindeverbindung form- und kraftschlüssig in einem, als Halterohr ausgebildeten Rohrstück des Tandemgefechtskopfes gehalten. Ein Schwadenschutz sichert das Sekundärgeschoß unmittelbar an der Gewindeverbindung. Bei auftretenden Detonationsschwaden der bereits gezündeten Hohlladung wird der Schwadenschutz in den sich nach rückwärts verengenden Ringraum hinein komprimiert und dadurch die eigentliche Dichtwirkung erzielt. In einer zweiten Phase erfolgt gleichzeitig mit einer Vorschubbewegung des Sekundärgeschosses aufgrund seiner Massenträgheit das Aufbrechen eines, mit dem Rohrabschnitt einstückig verbundenen Konusabschnittes des Gehäuses des Tandemgefechtskopfes. Dies führt zu einem Aufbrechen der Gewindeverbindung, so daß das Sekundärgeschoß aufgrund seiner Massenträgheit seine Freiflugphase bis zum Eintreffen in einen, von der Hohlladung bewirkten Krater eines Durchschußkanales.The secondary storey is positively and non-positively connected via a threaded connection a tube piece of the tandem warhead designed as a holding tube. A steam protection secures the secondary storey directly at the threaded connection. In the event of detonation swaths of the already ignited shaped charge the steam protection in the ring space narrowing backwards compressed into it, thereby achieving the actual sealing effect. In a second phase takes place simultaneously with a feed movement of the secondary floor due to its inertia, breaking open one with the pipe section integrally connected cone section of the housing of the tandem warhead. This leads to a break in the threaded connection, so that Secondary storey due to its inertia its free flight phase until Arrival in a crater of a bullet channel caused by the shaped charge.

Die Befestigungsteile und der Schwadenschutz sind einfach und kostengünstig herstellbar. Die Funktionssicherheit dieser Teile liegt ebenfalls vor.The fastening parts and the steam protection are simple and inexpensive producible. The functional safety of these parts is also available.

An embodiment of the invention is shown in the drawing. It shows:
Fig. 1
a tandem warhead with a secondary floor in partial section and
Fig. 2
1 in section and the adjacent housing parts.

Nach Figur 1 ist eine Sekundärgeschoß 1 in einem Rohrabschnitt 2 eines Gehäuses 3 eines Tandemgefechtskopfes 4 gelagert und über eine Gewindeverbindung 5 mit dem Gehäuse 3 verbunden. Ein Schwadenschutz ist mit 6 bezeichnet.According to Figure 1 is a secondary floor 1 in a pipe section 2 of a housing 3 of a tandem warhead 4 mounted and with a threaded connection 5 with connected to the housing 3. A steam protection is designated 6.

Der vordere Teil des Tandemgefechtskopfes 4 weist einen Abstandszünder 7 und eine Hohlladung 8 mit einem Zünder 9 auf. The front part of the tandem warhead 4 has a detonator 7 and a shaped charge 8 with an igniter 9.

Das Sekundärgeschoß 1 besteht aus zwei, über ein Gewinde 35 miteinander verschraubten Gehäuseteilen 10, 11. An den Gehäuseteilen 10, 11 sind Ogiven 44, 45 vorgesehen. Beide Ogiven 44, 45 weisen eine Splitterladung 23, 24 auf. Die Splitterladungen 23, 24 sind durch Hüllen 67, 68 gegen, aus Sprengstoff bestehenden Wirkladungen 13, 14 abgedeckt. Ein Zünder 20 trennt die beiden Wirkladungen 13, 14 voneinander.The secondary floor 1 consists of two, screwed together via a thread 35 Housing parts 10, 11. On the housing parts 10, 11 there are ogives 44, 45 intended. Both ogives 44, 45 have a splinter charge 23, 24. The fragments 23, 24 are by sleeves 67, 68 against, consisting of explosives Active charges 13, 14 covered. An igniter 20 separates the two active charges 13, 14 from each other.

Das, gegenüber der Hohlladung 8 im Kaliber kleinere Sekundärgeschoß 1 besitzt an seinem Umfang ein Gewinde 85 und dazu entsprechend der Rohrabschnitt 2 ein Innengewinde 86.That, compared to the shaped charge 8 in caliber has a smaller secondary floor 1 a thread 85 on its circumference and correspondingly the pipe section 2 Internal thread 86.

Das Gehäuse 3 weist einen konischen Abschnitt 87 mit dem daran einstückig angeordneten zylindrisch Rohrabschnitt 2 auf. Mit diesem Rohrabschnitt 2 ist ein Boden 88 mit einer der Ogive 46 entsprechenden Ausnehmung 89 über eine Gewindeverbindung 90 verschraubt. Die Ogive 46 liegt also mit einem sehr großen Flächenkontakt an dem Boden 88 auf. Demzufolge stellt die Gewindeverbindung 5 eine sogenannte Kontersicherung dar. Sie gewährleistet während des Transports die sichere Befestigung des Sekundärgeschosses 1 im Tandemgefechtskopf4.The housing 3 has a conical section 87 with the part arranged thereon cylindrical pipe section 2. With this pipe section 2 is a floor 88 with a recess 89 corresponding to the ogive 46 via a threaded connection 90 screwed. The ogive 46 is therefore in contact with a very large area on the floor 88. As a result, the threaded connection 5 sets so-called counter lock. It guarantees the during transport secure attachment of the secondary storey 1 in the tandem warhead 4.

Die Gewindeverbindung 5 zwischen dem Rohrabschnitt 2 und dem Sekundärgeschoß 1 ist in herkömmlicher Weise gegen Lösen gesichert, beispielsweise durch einen Sicherungslack.The threaded connection 5 between the pipe section 2 and the secondary floor 1 is secured against loosening in a conventional manner, for example by a security lacquer.

Der Schwadenschutz 6 ist in Richtung auf die Hohlladung 8 keilförmig ausgebildet. Hierzu liegt eine Stirnfläche 91 in einem spitzen Winkel 102 zur Hauptachse 92 des Tandemgefechtskopfes 4. Die rückwärtigen Flächen 93, 94 liegen an einer Konusfläche 95 und an einer rechtwinklig zur Hauptachse 92 liegenden Bodenfläche 96 an. Dieser Winkel 102 erstreckt sich zwischen 30° und 50°, vorzugsweise 45°, wie gezeichnet.The steam protection 6 is wedge-shaped in the direction of the shaped charge 8. For this purpose, an end face 91 lies at an acute angle 102 to the main axis 92 of the Tandem warhead 4. The rear surfaces 93, 94 lie on a conical surface 95 and on a bottom surface 96 lying at right angles to the main axis 92 on. This angle 102 extends between 30 ° and 50 °, preferably 45 °, as drawn.

Der Schwadenschutz 6 liegt in einem keilförmigen bodenseitig sich verkleinernden Ringraum 101, der durch den konischen Abschnitt 87 des Gehäuses 3 und das Sekundärgeschoß 1 gebildet ist. The steam protection 6 lies in a wedge-shaped bottom that shrinks on the bottom Annulus 101 through the conical section 87 of the housing 3 and the secondary floor 1 is formed.

Die Innenkontur des Schwadenschutzes 6 setzt sich zusammen aus einer, am Sekundärgeschoß 1 anliegenden Dichtlippe 97 und aus einer ebenfalls ringförmigen Stützfläche 98.The inner contour of the vapor protection 6 is composed of one on the secondary floor 1 adjacent sealing lip 97 and also a ring-shaped Support surface 98.

Das Gewinde 86 der Gewindeverbindung 5 liegt zu Beginn des Rohrabschnittes 2. Daran schließt sich in Richtung auf den Boden 88 ein freier Ringraum 99 an. Dieser Ringraum 99 ist im rückwärtigen Teil durch den Boden 88 begrenzt. Der Spalt 100 des Ringraumes 99 beträgt im Mittel ein bis zwei Millimeter. Die Länge des Ringraumes 99 beträgt etwa ein Drittel der Länge des Sekundärgeschosses 1.The thread 86 of the threaded connection 5 lies at the beginning of the pipe section 2. This is followed by a free annular space 99 in the direction of the bottom 88. This Annular space 99 is delimited in the rear part by floor 88. The gap 100 of the annular space 99 is on average one to two millimeters. The length of the Annular space 99 is approximately one third of the length of the secondary storey 1.

Bei Aufschlag des Tandemgefechtskopfes 4 auf eine nicht dargestellte, feindliche Deckung wird durch die Hohlladung 8 eine Krater mit anschließendem Durchschußkanal in der Deckung erzeugt. Bei Detonation der Hohlladung 8 beeinflussen die rückwärtigen Sprengstoffschwaden sowohl den Schwadenschutz 6 als auch das Gehäuse 3.Upon impact of the tandem warhead 4 on a hostile, not shown Coverage is through the hollow charge 8, a crater with subsequent bullet generated in the cover. If the shaped charge detonates, influence 8 the rear explosive swaths both the swath protector 6 and that Housing 3.

Bei zeitlich gestreckter Betrachtungsweise wird der Schwadenschutz 6 aufgrund des hohen Druckes der Sprengstoffschwaden innerhalb des noch bestehenden Gehäuses 3 komprimiert, so daß die Sprengstoffschwaden nicht durch die Gewindeverbindung zum Boden 88 gelangen können. Hierbei wird die Dichtlippe 97 in entsprechender Richtung umfangsseitig auf das Sekundärgeschoß 4 gepreßt. Auch liegt ein erhöhter Anpreßdruck des Schwadenschutzes 6 an den Flächen 95, 96 und am Gewinde 85 vor. Der Schwadenschutz 6 hält die Sprengstoffschwaden natürlich nicht auf Dauer ab, sondern nur im entscheidenden Mikrosekunden-Bereich. In diesem Zeitbereich lenkt die konische Stirnfläche 91 das Druckmaximum geringfügig nach außen, also weg von der Gewindeverbindung 5.
In einer zweiten Phase bricht das Gehäuse 3 zusammen mit der Gewindeverbindung 5, wobei sich das Sekundärgeschoß 1 aufgrund seiner Massenträgheit bereits in einer Vorwärtsbewegung befindet. Aufgrund des aufbrechenden Gehäuses 3 liegt eine Druckentlastung bezüglich des Sekundärgeschosses 1 vor, so daß eine Gefahr des Aufbrechens des Sekundärgeschosses 1 aufgrund der Sprengstoffschwaden nicht mehr besteht.When viewed in a stretched manner over time, the vapor protection 6 is compressed due to the high pressure of the explosive vapor within the still existing housing 3, so that the explosive vapor cannot reach the floor 88 through the threaded connection. Here, the sealing lip 97 is pressed on the secondary floor 4 in the corresponding direction on the circumference. There is also an increased contact pressure of the vapor protection 6 on the surfaces 95, 96 and on the thread 85. The vapor protection 6 naturally does not keep off the explosive vapor in the long term, but only in the crucial microsecond range. In this time range, the conical end face 91 guides the pressure maximum slightly outwards, that is to say away from the threaded connection 5.
In a second phase, the housing 3 breaks together with the threaded connection 5, the secondary storey 1 already being in a forward movement due to its inertia. Due to the opening of the housing 3, there is a pressure relief with respect to the secondary storey 1, so that there is no longer a risk of the secondary storey 1 being broken open due to the explosive vapor.

Der Rohrabschnitt 2 bleibt aufgrund des Schwadenschutzes stabil, d. h., er wird durch die Detonationsschwaden nicht zerstört. Damit erfolgt bei der Vorwärtsbewegung des Sekundärgeschosses 1 aufgrund des Ringraumes 99 eine Lagestabilisierung des Sekundärgeschosses 1. Dadurch ist gewährleistet, daß das Sekundärgeschoß 1 eine gewisse Führung erhält um eine stabile freie Flugphase durchführen zu können und zwar bis zum Auftreffen in den Krater des Durchschußkanales.The pipe section 2 remains stable due to the vapor protection, i. that is, he will not destroyed by the detonation swaths. This takes place during the forward movement of the secondary storey 1 is stabilized due to the annular space 99 of the secondary floor 1. This ensures that the secondary floor 1 receives a certain guidance in order to carry out a stable free flight phase to be able to do so until it hits the crater of the bullet canal.

Der Schwadenschutz besteht aus einem elastischen, also komprimierbaren Kunst stoff. Es eignen sich hierfür PVC und auch PP, PA, PE, POM oder PTFE.The steam protection consists of an elastic, compressible art material. PVC and also PP, PA, PE, POM or PTFE are suitable for this.
