  • Plasma torch incorporating electrodes separated by an air gap and squib incorporating such a torch
    Patent number: 6740841
    Abstract: A plasma torch including at least two electrodes separated by an insulating cylindrical case having a void, wherein the electrodes are separated by a distance (D) for forming an igniting arc therebetween when the electrodes are connected to a voltage, the distance (D) and the voltage being selected to form substantially a 1 Megavolt/meter electrical field between the electrodes, for forming an arc and causing plasma to be generated from the plasma generating material.
    Type: Grant
    Filed: November 1, 2001
    Date of Patent: May 25, 2004
    Assignee: Giat Industries
    Inventors: Luc Brunet, Jean Mary Lombard, Jean Francois Pierrot, Jean Luc Taillandier
  • Plasma torch incorporating a reactive ignition tube and igniter squib integrating such a torch
    Patent number: 6703580
    Abstract: The invention relates to a plasma torch (1) comprising at least two electrodes (7, 8) separated by a cylindrical insulating case (6) delimiting an internal volume, said electrodes connected by a conductive ignition fuse (11) placed in the internal volume. This torch is characterized in that the fuse (11) comprises at least one conductive material associated with at least one energetic material or one able to react with the conductive material. Application to the ignition of the propellant charge of a munition.

  • Plasma torch comprising electrodes separated by an air gap and igniter incorporating same
    Publication number: 20020134767
    Abstract: The invention relates to plasma torch (1) comprising at least two electrodes (7, 8) separated by an insulating cylindrical case (6) delimiting an inner volume, said torch wherein the electrodes (7, 8) are separated by a sufficiently small distance (D) for an igniting arc to appear between the electrodes (7, 8) when a serviceable voltage supplied by a generator (19) is applied between them.
