  • Patent number: 4549489
    Abstract: A cartridge for launching electromagnetic decoys with multiple charges comprises an elongated tube having an open upper end and a closed lower end, in which a plurality of flat holders, containing electromagnetic decoys are stacked over the length of the tube. At least one of the upper and lower surfaces of each flat holder is a conical surface in the shape of a flattened cone and each flat holder is provided in its lower part with a pyrotechnic charge able to project it upwards and to disperse the decoys. Each charge is connected to an adjacent charge by a pyrotechnic retarder and the upper most charge of the stack is provided with at least one pyrotechnic initiator, such that the arrangement formed by the initiator, the chargers and the retarders forms a continuous pyrotechnic chain, in order to allow, after detonation of the initiator, the successive ejection of the flat holders in a predetermined timed sequence.

  • Patent number: 4524670
    Abstract: Located below an aircraft is a support rod (1) provided with female engagement members (10). Standard missile launcher modules are provided on their flat upper wall with counterpart male engagement members (20). The engagement members (10 and 20) cooperate in the manner of dovetails and for each module location, they are separated from each other according to the same geometric progression along the support rod (1) and the upper wall of the module (2). A device comprising a cam (27) and lever (273) makes it possible to ensure at the same time the translation necessary for locking of the dovetail, as well as the making of contact between the electrical connector members.

  • Patent number: 4479417
    Abstract: A standard launcher module for various missiles, in particular flares, comprises a flat wall forming a base, provided with male engagement members. In the position engaged on the support incorporated in the aircraft, a connector is active. Provided in a central groove is a series of electrical initiators connected selectively to the connector and located opposite counterpart relay channels which lead respectively to the useful charges. A sliding bar located in the groove has orifices, located according to the working geometry of the initiators. Finally, a motor connected to the connector allows the movement of the bar between a safety position and an armed position.

  • Patent number: 4476784
    Abstract: The present invention relates to a mine incorporating a pressure plate. Such a mine comprises, inter alia, a pressure plate, a pyrotechnic firing chain and an arming device. The pyrotechnic chain comprises a firing relay rotatably mobile in two substantially perpendicular directions to ensure alignment of the pyrotechnic chain by a double rotation of a support disc about a shaft and a mobile member about an axis. Maneuvering of an arming button ensures rotation of the mobile member; a clockwork timer device ensures rotation of the support disc. A further feature of the invention resides in the reversibility of arming, the opposite maneuver of the arming button ensuring that the mobile elements of the mine return to their intial position. In addition, an anti-blast device is incorporated in the pressure plate. The invention is applicable to anti-tank mines.

  • Patent number: 4454816
    Abstract: This invention relates to the safety of ammunitions.The projectile of a cartridge has a base which houses a safety stop consisting of a transversely slidable valve. A device ensures that the valve cannot be released until the projectile has been subjected to a powerful acceleration. Another safety device very advantageously ensures that the pyrotechnical chain inserted in the base functions only when the pressure of the ejection charge has been able to release a sealing-block.In particular, the invention may be applied to infra red window releasing cartridges.

  • Patent number: 4374494
    Abstract: Electro-magnetic decoy-launcher ammunition has an external housing, which houses an impeller in its lower section and encloses a charge of electro-magnetic decoy material which can be ejected by a thrust device when the impeller is excited. The charge remains in its tubular transfer container, and the thrust device is mounted within the transfer container and comprises a semi-rigid disc actuated by a piston, fitted with a peripheral projection, which defines with the disc an annular housing for a split ring for taking up play and a felt washer ensuring that the device is fireproof.

  • Patent number: 4222306
    Abstract: A decoy-launching pack for mounting on a directional carriage for foiling or frustrating weapons guidance systems. The pack comprises a rigid base suitable for positioning in a predetermined manner on said carriage, a firing means incorporated with said base for operation in conjunction with a firing-control component integrated in said carriage when said base is located thereupon, and a support located above and secured to said base and having the rack-shaped upper surface defining predetermined angled slopes. A firing transmission pyrotechnical chain extends from said firing means to the level of said angled slopes of the upper surface of said support, and a plurality of mortars are arranged with an ejection charge at the bottom bearing upon said angled slopes of said upper surface of said support, said mortars being predirected in the same plane, according to predetermined angles related to those of said angled slopes of the support surface.

  • Patent number: 4109406
    Abstract: A pyrotechnical mole trap includes:An elongate protective envelope which is open at its ends and which is intended to be placed in the mole run,An electrical contactor placed inside the protective envelope,Two displaceable triggers mechanically controlling the electrical contactor, each of these triggers being placed at one of the ends of the protective envelope,Two electrically fired deflagrating pyrotechnical charges, of which each is placed on the outside of the protective envelope near each of the triggers,A source of electric energy,An electrical circuit which connects together the electrical contactor, the pyrotechnical charges and the source of electrical energy and which is wired in such a way that the action of the mole on either of the triggers closes the electrical circuit and fires the pyrotechnical charge situated in the immediate proximity of that trigger.

  • Patent number: 4069762
    Abstract: An elementary emissive decoy for protecting, say, a ship from an infra-red guided missile has a water-tight case provided with floats and in which there is a liquid aerosol, a high calorific pyrotechnic composition core and an ignition device for the core.
