Definitions

  • the present invention relates to a torpedo recovery device.
  • torpedoes In the so-called drill configuration, used for performance testing and practice, torpedoes have negative buoyancy and so tend to sink at the end of the mission, thus making them difficult to recover for the next mission. It is an object of the present invention to provide a recovery device that can be housed inside the torpedo, without affecting the streamline contour of the torpedo, and which provides for positive buoyancy of the torpedo at the end of the mission or, at any rate, in predetermined activation conditions.
  • Document JP 2001 141400 discloses a torpedo recovery device as defined in the preamble of claim 1.
  • number 1 indicates as a whole a torpedo.
  • torpedo 1 comprises a recovery device 2 housed inside the torpedo, preferably at the front, close to the head 3.
  • Recovery device 2 comprises a substantially cylindrical supporting structure 4 forming a section of the overall structure of torpedo 1.
  • Structure 4 substantially comprises two tubular end portions 5, 6, of the same outside diameter as the torpedo and connected to the adjacent sections of the torpedo; and an intermediate portion 7 smaller in outside diameter and integral with one (6) of the tubular portions.
  • the intermediate portion of device 2 is defined externally by a frangible cylindrical housing 8 flush with the outer surface of tubular portions 5, 6.
  • frangible is used here in its widest sense, and applies equally to a housing made of a number of detachable parts, as well as to a one-piece housing that can be broken off or detached from structure 4.
  • housing 8 preferably comprises three 120° segments 9 fixed releasably to tubular portions 5, 6 by respective dove-tail joints 10, 11, and defining, with intermediate portion 7, an annular chamber 12 housing an inflatable bag 13.
  • Bag 13 comprises an annular sheet of high-pressure-resistant, rubber-coated canvas fixed hermetically along its lateral edges 17, 18 to the axial ends 15, 16 of intermediate portion 7 of structure 4 to form an air chamber 19 with intermediate portion 7.
  • each lateral edge 17, 18 of bag 13 is thicker than the rest of the sheet to form a raised toroidal rib 20, and is gripped between a first ring 21 fitted hermetically to the respective end 15, 16 of intermediate portion 7 and defining a shoulder 22 for the lateral edge, and a second ring 23 which slides onto the first and is locked in the grip position by a ring nut 24.
  • Shoulder 22 and second ring 23 are shaped to mate with lateral edge 17, 18, and in particular with relative rib 20.
  • bag 13 At rest, bag 13 is folded accordion-fashion inside annular chamber 12, and is kept in this position by a rip-off retaining belt 25 ( Figure 4 ) surrounding bag 13, and which comprises two fabric portions 26 laced together by laces 27 (only one shown) made of string with a predetermined break strength.
  • Bag 13 has three compensating valves 28 located 120° apart and offset, with respect to the centre line of the bag, towards lateral edge 17 (i.e. in use, towards head 3 of torpedo 1).
  • Each compensating valve 28 comprises a casing 29 fixed hermetically to an opening 30 in bag 13 and defining a cavity 31 communicating with air chamber 19 and the outside through respective openings 32, 33.
  • a shutter 34 associated with opening 32 is held in a normally closed position by a spring 35, and opens when the difference in pressure between air chamber 19 and the outside exceeds a predetermined threshold value defined by the setting of spring 35.
  • Structure 4 of the device houses a cylinder 36 of high-pressure, e.g. 300-bar, compressed air, which is fixed rigidly to structure 4 by three supports 37 (only one shown in Figure 3 ), each fixed to an inner flange 38 of structure 4 by screws 39.
  • a cylinder 36 of high-pressure e.g. 300-bar, compressed air
  • Cylinder 36 is connected to air chamber 19 by a pneumatic circuit comprising a fitting 40, an explosive-actuated valve 41, a pipe 42, and a diffuser 43.
  • valve 41 comprises a breakable partition 44 associated with an electrically-activated explosive actuating device (squib) 45, which receives an activating signal S resulting from an AND operation between a control signal C1 and a consent signal C2.
  • squib electrically-activated explosive actuating device
  • Control signal C1 is in turn the result of an OR operation between three signals : a signal S1 from a first pressure sensor P1; a signal S2 from a second pressure sensor P2; and an activation control signal S3.
  • Sensors P1 and P2 are set to define the minimum and maximum pressure respectively to which device 2 can be subjected during the mission, i.e. the compulsory operating depth range of the device.
  • Consent signal C2 is generated by a salinity sensor SS designed to only permit activation of device 2 in seawater, and so prevent accidental activation during transport or storage.
  • Device 2 operates as follows.
  • Device 2 is activated at the end of the torpedo 1 mission, either by activation control signal S3 (end of mission) or, in the event of a malfunction causing the torpedo to stray from the predetermined depth range, by pressure sensor P1 or P2 generating respective signal S1 or S2.
  • squib 45 breaks partition 44 to allow compressed-air flow from cylinder 36 through fitting 40, valve 41, pipe 42, and diffuser 43 into air chamber 19.
  • Diffuser 43 prevents high-pressure airflow from striking bag 13 directly and so damaging the material.
  • Bag 13 is thus inflated and, in so doing, snaps laces 27 and rips off retaining belt 25; and the outward mechanical thrust exerted by bag 13 also detaches segments 9.
  • Bag 13 is now free to expand and inflate fully into a toroidal shape about torpedo 1 to achieve positive buoyancy of torpedo 1.
  • compensating valves 28 maintain a constant pressure difference between air chamber 19 and the outside, to prevent bag 13 from expanding to breaking point as a result of the reduction in external pressure as torpedo 1 rises.
  • valves 28 are so located as to face upwards, and so be freely accessible, in the above recovery position.
  • One of the three compensating valves 28 is conveniently fitted with a line 46 fixed to shutter 34, and which is operated manually to deflate bag 13 and so assist recovery of torpedo 1.
  • device 2 provides for surfacing torpedo 1 at the end of the mission or in the event of a malfunction, thus simplifying recovery.
  • the structure of the device complies with the dimensional requirements, dictated by the geometry of the torpedo, of in no way affecting the streamline profile of the torpedo either before or during the mission, and of ensuring maximum safety during handling and use.
