Definitions
- the invention relates to a payload projectile according to the preamble of patent claim 1.
- the seat for the disk with the same diameter merges into the space for the detonator, while the rear surface of the lifting ring screw is formed flat.
- the lifting ring screw is first unscrewed, the igniter inserted and then the lifting ring screw screwed in again.
- the disc between the igniter and the discharge charge serves to protect the igniter: its central bore forms an ignition channel on the one hand to initiate the discharge charge and on the other hand protects the igniter during the build-up of pressure, so that the pressure that builds up is largely available for the discharge process.
- the ignition temperature of the discharge charge is in the region of 130 ° C.
- the fuse was actuated in time, despite the fact that the fuse had been actuated in time: the washer had come to rest against the flat rear surface of the lifting ring screw, and the passage cross-section of the ignition channel was not sufficient to prevent damaging internal pressure.
- the invention has for its object to provide a generic payload projectile in which an ejection of the submunition in the unlit payload projectile is avoided with certainty.
- a payload projectile has a carrier casing 10 with an oval region 12, an ejection disk 52 dividing the interior into a front pressure chamber 54 and a load chamber 46 containing submunition 50, and a detachable part 48. If the internal pressure building up in the pressure chamber 54 after the initiation of an ejection charge 18 exceeds a predetermined value, then the force causing an intended shear effect is transmitted directly to the part 48 for ejecting the submunition 50 via the ejection disk 52 and the column formed by the submunition 50.
- Fig. 2 shows in the pressure chamber 54, the receptacle 14 with a sleeve 16 for the ejection charge 18, a seat 20 for the disc 22 with its central bore (ignition channel) 24, a space 26 for a detonator 27 shown in dashed lines and a bore with an internal thread 28 for a lifting ring screw 30.
- the latter has a body with an external thread 32 and an unspecified surface for fixing a seal 33.
- In the rear surface 34 of the lifting ring screw 30 there is a passage 36 for the fuse 38.
- the space 26 for the igniter 27 has a larger clear diameter than the seat 20 for the disk 22.
- a pressure building up in the sleeve 16 can move the disk 22, overcoming a predetermined mechanical resistance, from its seat 20 in the direction of the longitudinal axis A of the bullet against the rear surface 34 of the lifting ring screw 30. (See dash-dot representation of disc 22). Protrusions 40 on the rear surface 34 ensure that the hot gases flow not only through the ignition channel 24, but also around the disk 22, as indicated by flow arrows 56 and 58, and through one of the fuse 38 (as not shown) released passage 35 can emerge without an internal pressure leading to the ejection of the submunition 50 being able to build up in the pressure chamber 54.
- the security against unintentional ejection of the submunition in a payload projectile can not only be ensured in a very simple manner, but also no additional manipulation is required when the payload projectile is fired, which - especially under operating conditions - not only resulted in a loss of time but also could also be forgotten.

Description
Die Erfindung betrifft ein Nutzlastgeschoß nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a payload projectile according to the preamble of patent claim 1.
Bei einem bekannten gattungsgleichen Nutzlastgeschoß geht der Sitz für die Scheibe mit gleichem Durchmesser in den Raum für den Zünder über, während die Rückseitenfläche der Heberingschraube planeben ausgebildet ist. Während der depotseitigen Lagerung und des Transports des Nutzlastgeschosses befindet sich aus Gründen der Sicherheit kein Zünder in dem für ihn vorgesehenen Raum. Zur Bezünderung des Nutzlastgeschosses am Einsatzort wird zunächst die Heberingschraube ausgedreht, der Zünder eingesetzt und dann die Heberingschraube wieder eingedreht. Im bezünderten Zustand dient die Scheibe zwischen Zünder und Ausstoßladung dem Schutz des Zünders: ihre zentrale Bohrung bildet einerseits einen Zündkanal zum Initiieren der Ausstoßladung und schützt andererseits während des Druckaufbaues den Zünder, so daß der sich aufbauende Druck weitestgehend vollständig für den Ausstoßvorgang verfügbar ist.In a known type of payload projectile of the same type, the seat for the disk with the same diameter merges into the space for the detonator, while the rear surface of the lifting ring screw is formed flat. For safety reasons, there is no detonator in the space provided for it during storage and transportation of the payload floor. To ignite the payload projectile on site, the lifting ring screw is first unscrewed, the igniter inserted and then the lifting ring screw screwed in again. In the ignited state, the disc between the igniter and the discharge charge serves to protect the igniter: its central bore forms an ignition channel on the one hand to initiate the discharge charge and on the other hand protects the igniter during the build-up of pressure, so that the pressure that builds up is largely available for the discharge process.
Während die Schmelzsicherung in einem Durchlaß der Heberingschraube bereits bei einer Temperatur von etwa 95 C anspricht, liegt die Entzündungstemperatur der Ausstoßladung im Bereich um 130°C. Trotzdem kam es bei Brand oder starker Sonneneinstrahlung trotz rechtzeitig betätigter Schmelzsicherung zum unbeabsichtigten Ausstoß: Die Scheibe hatte sich nämlich gegen die ebene Rückseitenfläche der Heberingschraube gelegt, und der Durchtrittsquerschnitt des Zündkanals reichte nicht aus, um einen schädlichen Innendruck zu verhindern.While the fuse in a passage of the lifting ring screw already responds at a temperature of approximately 95 ° C, the ignition temperature of the discharge charge is in the region of 130 ° C. In spite of this, in the event of fire or strong sunlight, the fuse was actuated in time, despite the fact that the fuse had been actuated in time: the washer had come to rest against the flat rear surface of the lifting ring screw, and the passage cross-section of the ignition channel was not sufficient to prevent damaging internal pressure.
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgleiches Nutzlastgeschoß zu schaffen, bei welchem ein Außstoß der Submunition beim unbezünderten Nutzlastgeschoß mit Sicherheit vermieden wird.The invention has for its object to provide a generic payload projectile in which an ejection of the submunition in the unlit payload projectile is avoided with certainty.
Gelöst wird diese Aufgabe nach der Lehre des Patentanspruchs 1 mit den im kennzeichnenden Teil angegebenen erfinderischen Merkmalen.This object is achieved according to the teaching of claim 1 with the inventive features specified in the characterizing part.
Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten bevorzugten Ausführungsbeispiels näher erläutert.The invention is explained below with reference to a preferred embodiment shown in the drawing.
Es zeigen, jeweils in einem längsaxialen Schnitt,They show, each in a longitudinal axial section,
- Fig. 1 ein Nutzlastgeschoß mit der Erfindung undFig. 1 is a payload floor with the invention and
- Fig. 2 einen zum Verdeutlichen von Einzelheiten vergrößert dargestellten Vorderteil des Gegenstands nach Fig. 1.FIG. 2 shows a front part of the object according to FIG. 1 shown enlarged to clarify details.
Gemäß Fig. 1 weist ein Nutzlastgeschoß eine Trägerhülle 10 mit einem Ogivalbereich 12, einer den Innenraum in einen vorderen Druckraum 54 und einen Submunition 50 enthaltenden Lastenraum 46 unterteilenden Ausstoßscheibe 52 und einen absprengbaren Teil 48 auf. Überschreitet der sich nach dem Initiieren einer Ausstoßladung 18 im Druckraum 54 aufbauende Innendruck einen vorgegebenen Wert, dann wird über die Ausstoßscheibe 52 und die durch die Submunition 50 gebildete Säule die eine beabsichtigte Scherwirkung verursachende Kraft unmittelbar auf den Teil 48 zum Ausstoßen der Submunition 50 übertragen.1, a payload projectile has a
Fig. 2 zeigt im Druckraum 54 die Aufnahme 14 mit einer Hülse 16 für die Ausstoßladung 18, einen Sitz 20 für die Scheibe 22 mit deren zentraler Bohrung (Zündkanal) 24 einem Raum 26 für einen gestrichelt eingezeichneten Zünder 27 sowie eine Bohrung mit Innengewinde 28 für eine Heberingschraube 30. Letztere weist einen Körper mit Außengewinde 32 und eine nicht näher bezeichnete Fläche zum Fixieren einer Dichtung 33 auf. In der Rückseitenfläche 34 der Heberingschraube 30 befindet sich ein Durchlaß 36 zur Schmelzsicherung 38. Der Raum 26 für den Zünder 27 weist einen größeren lichten Durchmesser auf als der Sitz 20 für die Scheibe 22. Wird in Abwesenheit des Zünders 27 die Ausstoßladung 18 ungewollterweise initiiert, kann ein sich in der Hülse 16 aufbauender Druck die Scheibe 22 unter Überwindung eines vorgegebenen mechanischen Widerstandes aus ihrem Sitz 20 in Richtung der Geschoßlängsachse A gegen die Rückseitenfläche 34 der Heberingschraube 30 bewegen. (Siehe strichpunktierte Darstellung der Scheibe 22). Durch Vorsprünge 40 auf der Rückseitenfläche 34 wird gewährleistet, daß die heißen Gase nicht nur durch den Zündkanal 24, sondern auch um die Scheibe 22 herum, wie durch Strömungspfeile 56 und 58 angedeutet, strömen und durch einen von der Schmelzsicherung 38 (wie nicht dargestellt) freigegebenen Durchlaß 35 austreten können, ohne daß sich im Druckraum 54 ein zum Ausstoß der Submunition 50 führender Innendruck aufbauen kann. Mit der Erfindung läßt sich die Sicherheit gegen unbeabsichtigten Ausstoß der Submunition bei einem Nutzlastgeschoß nicht nur auf sehr einfache Weise gewährleisten, sondern es bedarf auch beim Bezündern des Nutzlastgeschosses keiner zusätzlichen Manipulation, welche - vor allem unter Einsatzbedingungen - nicht nur zu einem Zeitverlust führte, sondern auch vergessen werden könnte.Fig. 2 shows in the
