Definitions

  • the present invention relates to a pyroacoustic device forming a jammer or decoy, for the protection of submarines or surface buildings.
  • the object of the present invention is to propose a new device more effective than the known prior devices with regard to torpedo homers.
  • a housing 100 cylindrical of revolution around a vertical O-O axis in use.
  • This box 100 is connected to a positioning structure controlled underwater.
  • a structure of controlled positioning underwater can be the subject of many modes of production.
  • it is an inflatable buoy 240 to which the box 100 is connected by a cord 2100, as will be explained later.
  • the positioning structure can understand not an inflatable buoy, but an inflated buoy from the origin, or any equivalent means able to float on water to support the housing 100 via the rope 2100, or even capable of control the descent of the housing 100.
  • the structure of positioning may not include something floating on the surface water, but something, such as a parachute canopy suitable for control the descent of the housing 100 in the water.
  • the housing 100 accommodates a plurality of loads 110 adapted for each generate an acoustic effect. According to the representation given on the FIG. 1, these charges 110 which open onto the external surface of the housing 110 are distributed on a propeller centered on the axis O-O.
  • the housing 100 houses means adapted to initiate successively loads 110 according to a controlled timing.
  • these means consist of a motor reducer 120 placed in the upper part of the housing 100 and associated with a power supply stack 130.
  • the reduction motor 120 drives a shaft 122 centered on the O-O axis.
  • the shaft 122 is non-cylindrical in revolution. He is in taken with a plate 124 which, on the one hand is engaged in a spiral guide formed on the housing 100 and on the other hand carries at least one brush 125 electrically conductive, preferably two brushes electrically conductors 125, 126 so that when driving the shaft 122 by the motor 120, the brushes 125, 126 come into contact successively with igniter pads of different charges 110.
  • Each of the charges 110 is preferably formed of a housing 111 generally cylindrical in revolution, tapered radially towards inside the case 100.
  • Each case 111 houses a sound composition 112.
  • each box 111 is provided with a ejection flush 113.
  • On the interior thereof each housing 111 further includes a pyrotechnic delay 114.
  • an igniter 115 is carried by the structure of the housing 100 receiving the charges 110 next to each flush 113.
  • Each igniter 115 communicates with an ejection flush 113.
  • each igniter 115 has a power supply terminal in contact with the housing 100 electrically conductive on the one hand, and a second terminal accessible by look of the movement path of the brushes 125, 126 on the other hand.
  • the housing 100 can contain 700 loads 110 implemented in steps of 0.25 seconds.
  • each charge 110 is ensured between the housing 100, for example by means of an O-ring 116 engaged on the radially internal end of each housing 111.
  • each case 111 is held in the case 100 by means capable of yielding during the implementation of the hunt ejection 113.
  • Such temporary retention means can be formed for example a toothed washer 117 engaged with a stud 118 formed on the radially outer surface of each housing 111 and coming from elsewhere in engagement with the internal surface of each housing of the housing 100 receiving a charge 110.
  • Priming the battery 130 powers the motor 120. This drives the rotary striker assembly 140 which is designed to strike automatically the percussion caps 130 according to its displacement, according to an adequate timing. Percussion primers 130 initiates the pyrotechnic ejection hunts 113 which ignite the pyrotechnic delays 114 and eject the pyroacoustic charges elementary 110.
  • each pyrotechnic delay 114 initiates the associated sound composition 112, thus creating the desired acoustic effect.
  • FIGS. 7 to 9. Another variant embodiment has been illustrated in FIGS. 7 to 9. according to which the housing 100 accommodates several circular pancakes 150 stacked axially.
  • each wafer 150 accommodates itself a plurality of elementary charges 110, in chambers which open axially onto a main surface of the pancakes 150, orthogonal to the axis O-O during storage.
  • the housing 100 can thus accommodate by example 30 pancakes each containing for example 18 loads 110.
  • the motor 120 is replaced by an electronic box 121 connected by via a bundle of cables 128 to 1150 ejection channels inserted between the wafers 150.
  • each wafer 150 carries a electric igniter 152, preferably in the central position.
  • Each load 110 of the embodiment illustrated in FIGS. 7 to 9 consists of a body 111, preferably made of plastic, which contains the sound composition 112, and a pyrotechnic delay 114.
  • the priming of the battery 130 supplies the electronic unit 121. This initiates the electrical igniters 152 of each wafer according to a adequate sequencing.
  • the initiation of an igniter 152 causes the ignition of a flush associated ejection 1150, which causes the separation of the wafer 150, the release of its elementary pyroacoustic charges and the ignition of all of the pyrotechnic delays 114 of these charges 110.
  • each delay 114 has a different duration.
  • each pyrotechnic delay 114 initiates the associated sound composition 112, creating the desired acoustic effect. Sequencing of the case electronics 121 is such that the end of combustion of the last delay 114 of a wafer 150 corresponds to the initiation of the next wafer 150.
  • This munition 200 comprises an essentially cylindrical body of revolution, around an axis O-O.
  • This body includes a primary part 210 and an abutment 250.
  • the primary part 210 is located at the end of the rocket 200. It houses preferably stabilizing fins 220, a propulsion motor 212 (this motor can be a powder motor) and preferably a set with parachute 230.
  • the secondary part 250 houses the useful part of the load comprising the buoy structure 240 and the housing 100 containing the charges sound 110.
  • the ammunition 200 also has an impeller pyrotechnic 235 placed between the primary part 210 and the secondary part 250 to separate the engine 212 from the 240/100 payload when it is initiation.
  • a second impeller located in the rocket warhead allows also, after firing, to request a piston ensuring the deposition of the 240/100 payload out of its container tube to free the device from countermeasure.
  • the firing of the first and second powder impellers is done, for example, through an electronic device.
  • parachute assembly 230 can be housed in the secondary part 250 and not in the primary part 210.
  • the engine 212 can be associated with a parachute asymmetrical ensuring a change of trajectory to the engine 212, after initiation of the first impeller, to prevent the motor from disturbing the payload path 240/100.
  • a parachute can comply with the provisions described in document FR-A-2 724 222.
  • the operation of the system according to the present invention is basically the following.
  • the ammunition is fired at an elevation and with a precise flight time calculated to reach the desired range ( Figures 11a and 11b).
  • the chain pyrotechnic is initiated and the rear impeller is ignited. This ensures the separation of engine 212 and payload 240/100.
  • Engine 212 is ejected backwards.
  • the brake parachute 230 still not deployed, and the 240/100 payload is ejected forward. A halyard connecting the two previous sets are loosened until reaching tension.

  • the 240/100 payload reaches the surface of the water.
  • a sensor ensures the separation of the buoy structure 240 and the housing 100 and authorizes the unwinding of the connection cord 2100 between them.
  • the initiation of the housing 100 is operated when the rope 2100 by which the box 100 is suspended from the buoy structure 240, is tensioned.
  • the buoy structure 240 can be inflated by any means suitable for impact on water, for example by a CO2 capsule activated by a striker itself released during the fusion of a salt block fuse in contact with water, for example NaCl.
  • the means ensuring the temporary connection, before impact on water. between the buoy structure 240 and the housing 100 can be the subject of many embodiments.
