  • Patent number: 10415937
    Abstract: An electromagnetic mobile active system for fitting in a missile with a detonation-operated magnetic field compressor. The magnetic field compressor has at least one stator coil and at least one armature casing, which is at least partially surrounded by the stator coil and kept at a radial distance. The magnetic field compressor has at least one explosive charge embedded in the armature casing. The magnetic field compressor has at least one power source. For activating the detonation of the explosive charge, a trigger system is provided. The trigger system can be controlled by a pulse of current from the power source, depending on a signal supplied by the missile. A great amount of electrical energy can be generated in the stator coil by the detonation. For the directional radiation of the electrical energy generated by the detonation of the explosive charge, the active system has at least one directional antenna.

  • Patent number: 10228226
    Abstract: A monitoring device and system are provided for monitoring normal sequence of an initiation. The device includes at least one sensor in a region of an explosive charge and/or in a region of at least one ignition device for the explosive charge of the munitions system, and also a control device for evaluating output signals of the sensor with the control device connected to at least one ignition device in a controlling manner on a basis of the evaluation. At least one sensor is arranged at an output of a first ignition device for subdetonative initiation of the explosive charge. The control device is connected to a further ignition device and enables or inhibits it on a basis of a signal supplied by the sensor and assessed in the control device, and at least one sensor is designed for sensing pressure, temperature, light, electrical current or changing of mechanical states.

  • Patent number: 9829297
    Abstract: A device for the controlled initiation of a subdetonative reaction of an explosive charge arranged in a shell includes at least one explosive charge core extending in a region of a longitudinal axis of the explosive charge. A transverse dimension of the explosive charge core is adaptable to a radial extent of the shell in a longitudinal direction of the explosive charge, while a charging of the explosive charge core is set homogeneously or locally variably over a length of the explosive charge core with respect to a type of explosive material.

  • Patent number: 9766048
    Abstract: The invention relates to a device on the ignition device of a weapon, which can be triggered, for pressure relief, before or simultaneously with the initiation of the deflagrative reaction of the explosive charge, and has at least one channel that can be opened in a controlled manner and connects the interior of the weapon with the external surroundings of the weapon.
