  • Patent number: 11225879
    Abstract: An abradable element (7) for a turbomachine comprises a body (8) formed from an abradable material and extending between a wear face (11) and a bottom (9). The body comprises blind cavities (12) opening up into the wear face and filled in with a material with a colour different from the colour of the material forming the body of the element (7) to form wear indicators of the wear face (11) of the element (7).
    Type: Grant
    Filed: January 9, 2020
    Date of Patent: January 18, 2022
    Assignee: SAFRAN AIRCRAFT ENGINES
    Inventors: Antoine Robert Alain Brunet, Alexandre Franck Arnaud Chartoire, Eric Pierre Georges Lemarechal, David Joseph Serlan
  • Patent number: 10941667
    Abstract: A stator vane including a vane root, a vane tip, a leading edge extending between the root and the tip, the leading edge having a serrated profile having a succession of teeth and of troughs each having an amplitude and a thickness, wherein a series of at least three teeth and three consecutive troughs starting from the vane root and/or from the vane tip have a growing amplitude and/or thickness.

  • Patent number: 10392952
    Abstract: A guide vane for a dual flow aircraft turbine engine, the aerodynamic part of the vane including an inner duct for lubricant cooling extending in a main direction and being partly bounded by a pressure side wall and a suction side wall of the vane. A heat conduction matrix is lodged in the duct, and presents main heat transfer wings extending parallel to the direction, and laid out in staggered rows.

  • Patent number: 10378556
    Abstract: A guide vane for a dual flow aircraft turbine engine includes an aerodynamic part. The aerodynamic part includes an inner duct for lubricant cooling extending in a main direction and being partly bounded by a pressure side wall and a suction side wall of the vane. The aerodynamic part is embodied as a single piece, and includes heat transfer fins arranged in the duct expanding substantially parallel to a direction of the duct. The fins are spaced from each other depending on the direction of the duct and a transversal direction of the vane, so that at least some of the fins are arranged substantially staggered.

  • Publication number: 20170204879
    Abstract: The invention relates to a guide vane (24) for a dual flow aircraft turbine engine, the aerodynamic part (32) of the vane comprising an inner duct (50a) for lubricant cooling extending in a main direction (52a) and being partly bounded by a pressure side wall (70) and a suction side wall (72) of the vane. According to the invention, the aerodynamic part (32) of the vane is embodied from as a single piece, including also the heat transfer fins (80), arranged in the duct (50a) expanding substantially parallel to the direction (52a), the fins (80) being spaced from each other depending on the direction (52a) as well as a transversal direction (60) of the vane, so that at least some of the fins (80) are arranged substantially staggered.
