  • Pyrotechnic device
    Patent number: 11359545
    Abstract: A pyrotechnic device comprising a main pyrotechnic charge, a firing device for firing the main pyrotechnic charge, a discharge passage for discharging the gas generated by firing the main pyrotechnic charge, and an injector device configured to inject a cooling fluid into said gas discharge passage, so as to deliver gas, specifically for driving turbines, at temperatures that are relatively low, and a method of cooling gas generated by firing the main pyrotechnic charge by injecting the cooling fluid.
    Type: Grant
    Filed: November 17, 2017
    Date of Patent: June 14, 2022
    Assignee: Safran Helicopter Engines
    Inventors: François Danguy, Laurent Paul Lattanzio Fabbri, Romain Maurice Henri Yannick Gauthier, Didier Paul Saucereau

  • Sealing system and turbopump comprising such a system
    Patent number: 10359048
    Abstract: A sealing system for at least one floatingly mounted ring in a support for a rotary shaft rotatable about an axis directed along a longitudinal direction provides dynamic sealing between the shaft and the support. The system includes a coupling part interposed between the ring and the support, whereby the ring is secured to the support. A first cylindrical type joint directed with respect to a first transverse direction provides a joint between the support and the coupling part. A second cylindrical type joint directed with respect to a second transverse direction perpendicular to the first transverse direction provides a joint between the ring and the coupling part. A turbopump includes such rotary shafts and sealing systems.
