Definitions

  • the technical sector of the present invention is that of missiles of the cargo projectile type, carrying a plurality of sub-assemblies arranged inside the body of the missile having a generally cylindrical shape.
  • the present invention relates to a vehicle carrying ammunition or payloads, the operation of the vehicle and loads of which is conditioned by the presence of a liquid.
  • the ejection and / or firing of submunitions is subject either to the conditions of firing or flight of the carrier projectile, or to the impact speed of the latter on the ground.
  • Signaling devices for locating at sea consisting of a projectile containing a single charge with a specific effect, generally unique, of the smoke or lighting type.
  • the firing of the marking charge is triggered by the speed of impact of the device on the surface of the water.
  • patent WO-A-88 01364 which describes a flare, launched from a submarine, containing a composition projected into the air when the rocket is on the surface of the water.
  • This rocket notably includes a tilt detector and a sensor detecting the position of its nose above the water, conditioning the start of the launching and firing cycle of the lighting composition.
  • the energy required for the electrical circuit comes from seawater batteries activated by the opening of a valve when the rocket reaches the surface of the water.
  • This rocket containing a single illuminating charge, has the disadvantage of being powered by seawater batteries which are generally bulky to deliver sufficient power. They are also expensive and ill-suited to the operation of many payloads contained in a cargo projectile.
  • US Pat. No. 4,335,656 is known, describing a flare launched from a submarine and containing one or more smoke and / or lighting pyrotechnic compositions connected to a parachute.
  • the charge for ejecting the compositions is initiated by an electric detonator powered by a seawater battery.
  • An electronic timer connected to a detector for stable vertical position of the rocket body on the surface of the water, is placed between the battery and electric detonator.
  • the electrical circuit of this multi-charge rocket is also powered by a seawater battery, with the drawbacks mentioned above.
  • GB-A-2 210 147 showing a reversible arming mechanism for a pyrotechnic marker floating, comprising in particular an electric detonator powered by a battery activated by the presence of water.
  • This type of energy source does not provide sufficient constant power to ensure the proper functioning of a cargo projectile carrying several sub-assemblies initiated in a predetermined sequence.
  • Patent DE-A-2 209 445 which describes a cargo projectile containing several sub-assemblies of the hollow charge type arranged in a cylindrical body, for destroying ships and more particularly submarines.
  • This cargo projectile launched above the target, disperses the sub-assemblies at altitude thanks to a central dispersal charge and detonating cords which cut the cylindrical body.
  • Each sub-assembly is autonomous and in particular comprises a thermal battery activated by a heating element and a switch of the electric circuit closed by water connecting its two electrodes when the sub-assembly is immersed. If one of the subsets does not reach its target, it self-destructs by explosion of the shaped charge after a predetermined delay.
  • thermal batteries like seawater batteries, have a limited operating time after activation, preventing their use in long-term sequential shooting.
  • this cargo projectile only allows simultaneous ejection of the sub-assemblies. Only the self-destruction of each sub-assembly by explosion of the hollow charge is planned and not that of the cargo projectile carrying these sub-assemblies.
  • the devices described in the patents mentioned above provide for bootable batteries to provide the energy necessary for their operation, having multiple constraints incompatible with the requirements of a multi-purpose cargo projectile.
  • the object of the present invention is to remedy the drawbacks mentioned above by proposing a missile-type missile carrier carrying ammunition or payloads, capable of triggering the ejection and / or the operation thereof, whatever the conditions in which the machine is brought into contact with a liquid medium, and comprising an electric circuit supplied in a sustainable manner with an autonomous energy source operating independently of the liquid medium.
  • the present invention also aims to allow the choice of ammunition or identical or varied payloads arranged in the machine, in order to obtain simple or multiple effects, adapted to the circumstances of use.
  • Another object of the invention is to ensure automatic destruction of the machine, regardless of its launching conditions, the initiation and the operation of the sub-assemblies carried by the machine.
  • the subject of the invention is a device of the multi-purpose cargo projectile type carrying sub-assemblies such as in particular ammunition or payloads, capable of operating in the presence of a liquid, characterized in that it comprises a sub-assembly control device provided with an electrical circuit comprising an autonomous energy source and a switch which closes the circuit in the presence of the liquid.
  • control device comprises a central unit managed by a microprocessor ensuring the operation of the sub-assemblies according to a predetermined sequence.
  • control device comprises a detector for positioning the machine with respect to the surface of the liquid medium.
  • the central unit may include an electronic timer, conditioning the start of the operating sequence of the sub-assemblies.
  • control device can be provided with a pyrotechnic timer, replacing the electronic timer of the central unit.
  • the device may include at least one means of self-destruction, preferably by immersion of the body of the device, and a means of marking by coloring the surface of the water.
  • the subsets can be initiated simultaneously, continuously or discontinuously.
  • each sub-assembly can occur after their ejection from the carrier, or directly into the body of the machine without prior ejection.
  • At least one of the sub-assemblies can be constituted by a smoke, illuminating charge, of infrared marking, decoying, mining, demining, or rejoicing fires for example; or by a load comprising a mixture of two or more of the different types of loads listed.
  • this machine Because of its versatility, this machine has the advantage of being usable from many air vehicles (drome, aircraft, missile, rocket, etc.), sailors or submarines (ship, torpedo, etc.), for perform different missions (visual, sound and / or infrared marking, decoying, marking, mining, firing of bonfire lights, etc.), these missions can be combined with one another.
  • This machine has the advantage of operating thanks to a single and autonomous energy source, consequently independent of the liquid medium, capable of supplying the electrical circuit during long duration sequences.
  • Another advantage lies in the possibility of significantly increasing the marking time compared to existing signaling devices, by combining several vehicles carrying multiple charges drawn continuously.
  • This invention has the advantage of providing machines with very low manufacturing costs and simplified logistics.
  • the vehicles carrying variegated underloads make it possible, for example, to advantageously resolve the problems encountered by the naval airship during operations taking place in foggy weather.
  • a missile-type missile of the invention consisting in particular of a generally tubular hollow body 1 containing several sub-assemblies 2 arranged longitudinally in its central part. One end of the body is closed by a shutter having as many orifices as there are sub-assemblies contained in the machine, the other end comprising a first element 3 housed in the body and secured by any known means (crimping by example) with a second element 4 of substantially semi-spherical shape external to the body 1.
  • the first element 3 comprises the lower end of each sub-assembly provided with a firing means 12 adapted to the type of sub-assembly concerned, this means possibly being an electric or electropyrotechnic igniter 12 of known type for example.
  • This first element also comprises a cylindrical tube 18 connecting the self-destruction means 7 of the machine (included in element 4) with the central part of the machine containing the sub-assemblies.
  • the second extreme element 4 comprises in particular two water inlet orifices 20, arranged transversely and communicating with a longitudinal channel containing a water switch 6 provided with two electrodes connected to a central control unit 5, and two self-destruct means 7 identical also connected to the central unit.
  • the water switch 6 consists of two electrodes passing through an insulator having a conical end having an apex angle of approximately 30 °, the ends of each electrode being slightly set back relative to the tip of the cone.
  • Each self-destruct means 7 (FIG. 3), also ensuring the marking by coloring of the surface of the water near the machine, consists of a hollow body having an opening closed by a straw 22 forming an obstacle between the liquid medium and a coloring substance 23 contained in the body.
  • An electric or electro-pyrotechnic igniter 13 of known type (possibly identical to the igniters 12 mentioned above), connected to the central unit 5, is housed in the center of the body also comprising two orifices 19 made in the part opposite to that receiving the straw 22 .
  • FIG. 4 shows more particularly the device for controlling the subassemblies 2 contained in the body 1 of the machine.
  • This control device comprises an electrical circuit open or closed by the water switch 6 associated with a positioning detector 9 of the machine relative to the surface of the water, the ignition means 12 and 13, connected to the central control unit 5 comprising a microprocessor 10, the entire circuit being supplied by a stabilized autonomous energy source 8, via a switch electronics 16 associated with a relay and a stabilizer 17.
  • This autonomous energy source 8 integrated in the central control unit 5 consists of two "button" lithium batteries having a long service life.
  • This energy source is autonomous and therefore independent of the ambient environment. In the standby state or in the initial state, the energy consumption is zero. The electric current is delivered only when the circuit is closed by the water switch 6 on the one hand, and the machine is stabilized in a vertical position on the surface of the water on the other hand.
  • the microprocessor conditions the charging of a capacitor 11 via an electronic timer 14.
  • the capacitor supplies the various firing means 12 and 13 according to the operating sequence determined by the microprocessor.
  • control device may include a pyrotechnic timer of known type (not shown), replacing the electronic timer 14 of the central unit mentioned above.
  • the central unit 5 also includes a self-test socket 15, making it possible to verify its correct operation.
  • the cargo projectile-type device containing a plurality of sub-assemblies is placed on the surface of the water by any means.
  • the machine stabilizes vertically on the surface of the water, allowing the positioning detector 9 to authorize the closing of the electronic switch 16 and supply of the entire circuit by the autonomous energy source 8 (batteries).
  • the microprocessor 10 analyzes the time of continuous presence of the water in contact with the electrodes of the water switch 6. When this time is greater than the predetermined time T measured by the timer 14, the microprocessor 10 authorizes the charging of the capacitor 11.
  • the microprocessor 10 verifies that the operating safety conditions, constituted by the presence of the liquid medium (water switch 6) and the vertical position of the machine (detector 9), are always met, it then authorizes the firing of the electro-pyrotechnic igniters 12.
  • the igniters 12 of the different sub-assemblies 2 are fired according to the operating sequence programmed in the microprocessor 10.
  • the specific effects produced can be simultaneous, continuous or discontinuous.
  • the self-destruct function of the machine is independent of the conditions of launching it, the initiation and the operation of each sub-assembly.
  • microprocessor 10 which authorizes the firing of the self-destruction means (s) 7 at the determined time of the operating sequence of the control device.
  • the self-destruction function can be coupled with a marking function by coloring the surface of the water near the machine.
  • the straw 22 for closing each self-destructing and coloring means 7 is punctured by the ignition of the igniter 13 authorized by the microprocessor.
  • the straw 22 being punctured the water attacks the coloring substance 23 of the self-destruct means 7 and dissolves it, which causes the coloring of the surface of the water near the craft.
  • the dissolution time of the coloring substance 23 and the coloring of the water depend in particular on the size and compression characteristics of this substance.
  • the two discs 21 are released, allowing the passage of water through the orifices 19.
  • the water enters the head of the machine, passes through the tube 18 and enters the body 1 .
  • the machine self-destructs by immersion at the bottom of the water.
  • the self-destruction means 7 can be used only to ensure marking by coloring of the surface of the water without causing the immersion of the machine.
  • the orifices 19 are removed or kept closed by any appropriate means, thus preventing water from entering the head and the body of the machine.
