  • Publication number: 20170114659
    Abstract: A turbine engine compressor has at least one annular row of variable-pitch stator vanes that are substantially radial and have pivots at their radial ends. The radially outer pivots of the vanes are received in first openings in a stator casing and the radially inner pivots are received in second openings in a floating ring that surrounds a rotor of the compressor. An annular stator part is inserted between the floating ring and the rotor of the compressor, and first sealing means are mounted between the stator part and the rotor of the compressor. Second sealing means are mounted between the floating ring and the stator part.

  • Patent number: 9441494
    Abstract: A rotor of a turbomachine, such as a multi-flow turbojet engine fan, has a disc including, on the rim thereof, substantially axial slots with a dovetailed cross-section, and blades mounted individually in the slots, an axial wedge positioned between the root of the blades and the bottom of the slots, and a transverse lock providing upstream axial immobilization of the blades in the slot thereof. The lock is guided in radial notches formed in the flanks of the slots and radially supported against the wedge. The axial wedge is immobilised in the upstream direction, butting up against a transverse annular component secured to the disc.

  • Patent number: 9109465
    Abstract: The invention provides a fan casing for a gas turbine engine, the casing having a substantially cylindrical portion that terminates at one end in an annular flange made of composite material. The flange includes at least one setback in a fraction of its thickness and at least one bolt for fastening pieces of equipment passing right through the flange in the axial direction, the bolt for fastening pieces of equipment having a head that presents a flat that is to bear flat against a rim of the setback, and a shank forming a stud for fastening pieces of equipment on the casing.
