  • Patent number: 10689992
    Abstract: The invention relates to part of a turbine engine comprising two arms passing through a stream of the turbine engine, wherein each arm comprises an outer surface and an aerodynamic linking device. The aerodynamic linking device comprises fairings extending between the two arms, compressible interface means interposed between the fairings and means for retaining the fairings in place by pressure in relation to the arms, which compress the interface means.
    Type: Grant

    Date of Patent: June 23, 2020
    Assignee: Safran Aircraft Engines
    Inventors: Thierry Kohn, Damien Cesar, Julien Sayn-Urpar
  • Patent number: 10532802
    Abstract: A propulsion assembly includes an engine surrounded by a nacelle, structure for draining the fluids from the engine and structure for guiding said fluids to a retention box. The retention box is arranged outside the engine and has a cavity for storing drained fluids. The retention box is fixed to a cowling of the nacelle and supported thereby.

  • Patent number: 10017238
    Abstract: Stub for discharging drained fluids for a propulsion unit. The stub includes a cavity for storing the drained fluids and at least one orifice for discharging the fluids contained in the storage cavity, and elements for measuring a difference in pressure outside the stub and a member for draining the storage cavity. The member is able to move between a first position of closing the discharge orifice and a second position of releasing the orifice, and is configured so as to move from the first to the second position when the difference in pressure is greater than, or equal to, a predetermined value.
