  • Device with gratings for ejecting microjets in order to reduce the jet noise of a turbine engine
    Patent number: 10408165
    Abstract: A device for reducing the jet noise of a turbine engine includes an outer cover having an inside wall defining the outside of an annular passage for passing a bypass stream from the engine, the wall of the outer cover including a plurality of microjet circuits, each including intakes for taking a gas stream from the bypass stream flow passage and leading to a single feed duct, which in turn opens out into the trailing edge of the outer cover via at least one ejection grating suitable for splitting the intake gas stream into a plurality of gas streams of right sections of dimensions less than a right section of the feed duct.
    Type: Grant
    Filed: March 25, 2016
    Date of Patent: September 10, 2019
    Assignee: SAFRAN AIRCRAFT ENGINES
    Inventors: Jacky Mardjono, Philippe Chanez, Jeremy Gonzalez, Maxime Koenig, Marc Versaevel, Franck Zaganelli, Henri Yesilcimen
  • Turbine engine nacelle fitted with a heat exchanger
    Patent number: 10294822
    Abstract: A nacelle of a turbine engine includes an external cowling, an internal cowling, and a heat exchanger associated with at least one circulation duct for a fluid. In particular, the circulation duct forms a recirculation loop through the heat exchanger, and the recirculation loop includes at least one circulation area extending at least partially along the external cowling in contact with a wall of the external cowling so as to allow exchange of heat by conduction with the air outside the nacelle.
