  • Publication number: 20190092469
    Abstract: A dispenser for storing and launching countermeasures from an aircraft, comprising an elongate body provided with at least one launch opening where the countermeasures are stored in cartridges, where the cartridges are interconnect to each other in a slidable manner, and where the cartridges are adapted to be tilted by a tilting means to a selected angle, such that the openings of the cartridges can be directed in a selected direction. The advantage of the invention is that a countermeasure can be directed in a desired angle before it is launched.

  • Publication number: 20130167711
    Abstract: A pyrotechnic countermeasure dispensing system. A first magazine accommodates countermeasures. The first magazine is mountable in a housing such that a contacting body of each countermeasure communicates with a contacting member of launching circuitry. An electronic unit is associated with the launching circuitry for actuating the countermeasure in the first magazine. A second magazine accommodates at least one countermeasure. The dispenser can be loaded with the first or second magazine. The second magazine is mountable in the housing such that a contacting body of the countermeasure communicates with a contacting member of the launching electronic circuitry via an adapter. The adapter includes an electrically insulated plate including a first side including a first point contacting the contacting body and a second side including a second point contacting the contacting member. The first and second points electrically communicate. A launch signal travels from the electronic unit to the contacting member.

  • Publication number: 20120091252
    Abstract: A system for protection of a vehicle against a possible threat approaching the vehicle. A sensor is configured to detect the possible threat and to transmit raw data and to continue the detection as long as there is a possible or confirmed threat. A control unit is configured to receive the raw data transmitted from the sensor and to evaluate the possible threat in view of the raw data to produce and transmit processed information. A counter-measure apparatus is configured to receive the processed information of the threat from the control unit if the evaluation by the control unit confirms that there is a threat. A launcher is configured to receive preliminary processed information of the direction of the threat from the control unit and to receive a launching signal from the control unit for launching the counter-measure apparatus towards the threat when the threat is confirmed.

  • Patent number: 8033225
    Abstract: A dispenser system for a platform. The dispenser system is configured to be mounted to the platform and connected to power- and control-system of the platform. The dispenser system includes a dispenser for countermeasure boxes. The dispenser is configured for non-pyrotechnic dispensing and opening of the boxes. Each box is sealed by a detachable closure that includes a first opening member and at least one passive, second opening member stationarily fixed to the dispenser, which is provided with a motor gear. The first and second opening members are configured for detaching the closure by mutual interaction simultaneously as each box under the influence of the motor gear is launchable from the dispenser.

  • Patent number: 7600477
    Abstract: A method for discharging countermeasures, a rocket launcher, and a dispenser arrangement. A space for one or more rockets in a rocket launcher is used as a carrier for a dispenser arrangement for countermeasures. The dispenser arrangement is designed with one or more cylindrical sections specially adapted to the rocket space in the rocket launcher. Equipment already adapted to aircraft can be used in supplementing the countermeasure equipment of the aircraft.

  • Patent number: 7373886
    Abstract: A method and an arrangement for discharging countermeasures from a carrier craft in the form of an aircraft or equivalent. The countermeasures are intended to be spread initially in the form of unit packs that, after they have left the carrier craft, are to screen the same from missiles approaching is guided by built-in sensors, or other threats. It is especially characteristic of the invention that the unit countermeasure packs are spread from the carrier transversely to the lying direction of the carrier craft.

  • Patent number: 6568292
    Abstract: A method and a device are provided for achieving a step-by-step feeding, based on a rotary shaft which optionally can be made to execute one or more well-defined, whole rotation turns. The step-by-step feeding is achieved by mechanical connection between a driver joined to an output shaft and the inner periphery of a drive drum directly driven by a drive motor and arranged concentrically relative to both the driving and the driven shaft. The system is based upon the driver being adjustable between a first driving position and a second locked position.

  • Patent number: 6539833
    Abstract: The present invention relates to a dropping device, preferably borne by a carrier aircraft, for distributing interference medium and especially electronic raspberry. The device according to the invention represents in principle an improvement to the device known through SE 8302508-0 and it is characterized firstly in that it has been provided with separately rotatable accelerator shafts (14, 15), which have the dual function firstly of acting as locks for an unwanted feed-out of interference medium packs (4) and secondly, when a feed-out has been activated, of executing this and giving the fed-out interference medium pack (4′) an increased feed-out speed, partly due to the device having been provided with a totally new, specially configured indexing mechanism.
