Definitions

  • the present invention relates to a countermeasure apparatus release device.
  • Release devices are known which are fitted to a rear portion of a countermeasure (jammer or decoy) comprising a tubular body housing an apparatus (e.g. receiver or transmitter) that must be released after the countermeasure is fired into the water.
  • a countermeasure jammer or decoy
  • an apparatus e.g. receiver or transmitter
  • the apparatus is normally housed in the cavity defined by the tubular body, and is pushed against the release device by a spring.
  • the release device plugs an exit opening in the tubular body to prevent expulsion of the apparatus by the spring.
  • the countermeasure is launched from launch tubes equipped with a high-pressure (200-250- or even 300-bar) compressed air cylinders to achieve the necessary range.
  • Number 1 in Figure 1 indicates as a whole a release device for releasing an apparatus housed inside a countermeasure.
  • device 1 is fitted to a rear portion 2 of the countermeasure (only shown partly), comprising a circular-section tubular body 3 housing an apparatus 5 (e.g. receiver or transmitter) that must be released after the countermeasure is fired into the water.
  • an apparatus 5 e.g. receiver or transmitter
  • tubular body 3 has a first end 3a connected to a connecting member 6; and a second exit end 3b having a circular exit opening 7 closed, in use, by device 1.
  • Apparatus 5 is housed in the cylindrical cavity defined by tubular body 3, and is pushed against release device 1 by a spring 9 interposed between apparatus 5 and connecting member 6.
  • Release device 1 plugs circular exit opening 7 to prevent expulsion of apparatus 5 by spring 9.
  • device 1 comprises a disk-shaped body 11 comprising two integral portions: a first cylindrical portion 11a of radius R1, and a thinner second cylindrical portion 11b of radius R2 greater than Rl.
  • First cylindrical portion 11a fits inside exit opening 7, and second portion 11b rests against end edges of tubular body 3.
  • Axes A1 and A2 are perpendicular to each other.
  • First and second seat 13, 15 are connected to each other by a cylindrical conduit 22 extending, coaxially with axis A1, between the bottom walls of seats 13, 15.
  • First seat 13 houses in fluidtight manner the cylindrical head 24 of a piston 25 having a rod 27 extending coaxially with axis A1.
  • first portion 27a of rod 27 engages hole 14b, and a second portion 27b of the rod engages cylindrical conduit 22.
  • Piston 25 is movable between a first stop position ( Figure 4 ), in which cylindrical head 24 rests on plug 14, and first portion 27a of the rod projects radially by a length H from plug 14; and a second stop position ( Figure 5 ), in which cylindrical head 24 is much closer to (or rests on) the bottom wall of seat 13, and first portion 27a of the rod does not project from plug 14.
  • Second seat 15 houses a programmed break member 30 fitted to plug 16, and which is broken as piston 25 moves from the first to the second stop position.
  • Each seat 17, 19 houses a retaining device 32 comprising a cylindrical head 34 coaxial with axis A2 and slid axially along seat 17, 19 by a spring 36 interposed between head 34 and plug 18, 20.
  • Head 34 is connected to a cylindrical rod 38 coaxial with axis A2 and engaging hole 18b, 20b.
  • Cylindrical head 34 is movable axially between :
  • Each seat 17, 19 has a drain conduit 40 extending from the bottom wall to conduit 22.
  • drain conduit 40 When piston 25 is in the first axial stop position ( Figure 4 ), drain conduit 40 is closed by the cylindrical surface of second portion 27b of the rod; and, when piston 25 is in the second stop position ( Figure 5 ), drain conduit 40 communicates with a drain conduit 41 formed in rod 27 and for connecting seats 17, 19 to seat 15.
  • rods 38 engage respective holes F ( Figure 4 ) in tubular body 3 to connect release device 1 stably to tubular body 3.
  • an inclined part P (shown schematically in Figures 4, 5 ) contacts and presses portion 27a of rod 27 from the first axial stop position into the second axial stop position.

Claims (8)

  1. Auslösevorrichtung (1) zum Auslösen eines Gegenmaßnahmegerätes (5), das in einem Hohlraum der Gegenmaßnahmeeinrichtung aufgenommen ist, wobei der Hohlraum eine Austrittsöffnung (7) aufweist, die durch die Auslösevorrichtung (1) abgeschlossen wird und über die das Gerät (5) ausgestoßen wird;
    wobei die Auslösevorrichtung (1) umfasst:
    einen Körper (11; 11a, 11b), der die Austrittsöffnung (7) verschließt;
    dadurch gekennzeichnet, dass
    wenigstens ein erstes Betätigungselement (27) axial zwischen einer ersten und einer zweiten Position bewegt werden kann, wenn die Gegenmaßnahmeeinrichtung abgefeuert wird; und
    wenigstens ein Halteelement (38) axial zwischen einer Halteposition, in der es mit einem Abschnitt (3) der Gegenmaßnahmeeinrichtung in Eingriff ist (F, 38), und einer Auslöseposition bewegt werden kann, in der es sich von dem Abschnitt (3) der Gegenmaßnahmeeinrichtung löst, um die Auslöseeinrichtung (1) von der Gegenmaßnahmeeinrichtung zu trennen; und dass
    Bewegung des ersten Betätigungselementes von der ersten Position an die zweite Position Ableiten eines Fluids aus dem Inneren einer Aufnahme (17, 19) aktiviert, um das Halteelement (38) von der Halteposition an die Auslöseposition zu bewegen.
  2. Vorrichtung nach Anspruch 1, wobei die Aufnahme (17, 19) einen Kopf (34) aufnimmt, der, wenn das Fluid abgeleitet wird, durch den Druck einer elastischen Einrichtung (36), die im Inneren der Aufnahme aufgenommen ist, axial an der Aufnahme (17, 19) entlang bewegt werden kann;
