  • Patent number: 6502512
    Abstract: The slapper type initiator comprises essentially: a connector unit (2) having two connection pins (3, 4), a first dielectric foil (5) with two drilled holes (6, 7), with a fuse (8) formed on the rear face of this first dielectric foil, a second dielectric foil (9) on the front face of which there are formed two metal pads (10, 11) facing said holes, a perforated plate (12) and a body (13) containing a pyrotechnic charge 14. The assembly is hermetically sealed. The first foil introduces a galvanic discontinuity that ensures a well-defined firing voltage, with a value high enough to prevent induced parasitic currents.

  • Patent number: 5723811
    Abstract: A warhead includes an explosive charge placed in a confinement casing and bounded towards a front portion by a liner, the entire warhead having an axis of symmetry of revolution. A detector is provided in front of the charge and processing and command circuits are provided in a rear portion of the charge. A multiple-point detonator is communicated with an axial space providing a detector-circuit link without harming the efficiency of the charge.

  • Patent number: 5657948
    Abstract: The disclosure pertains to a projectile guided by successive lateral gas jets by way of pairs of impellers. The impellers of one pair are fired so as to exert opposite moments of rotation. According to the disclosure, the impellers are brought together in two groups. Of the impellers of one pair, one is in one group and the other is in the other group. The impellers of each of the groups are separated by diode bulkheads that withstand the pressure of the impeller that is located on one side of the bulkhead and is fired first, but does not withstand the firing of the impeller that is located on the other side of the bulkhead and is fired second. The impellers of one group lead into one and the same nozzle. Thus, the making of the guidance impellers is simplified at the same time as the control of the guidance is improved.
