Abstract

Official abstract text for this publication.

A link part for a turbine engine which mounted between a fan cone and a fan disk supporting fan blades is provided. The link part includes an annular wall pierced by a plurality of orifices, each orifice for receiving a fastener member and terminated by a substantially perpendicular rim having an outer surface that provides an aerodynamic extension of the fan between an outer surface of the fan cone and an outer surface of a fan blade platform. The annular wall is made of a first material that is composite and is provided on an inner surface of the rim with a ring made of a second material that is different from the first and that is suitable for radially retaining the fan blade platform.

First claim

Opening claim text (preview).

What is claimed is: 1. A link part for a turbine engine, the link part being mounted between a fan cone and a fan disk supporting fan blades, said link part comprising: an annular wall pierced by a plurality of orifices, each orifice for receiving a fastener member and terminated by a substantially perpendicular rim having an outer surface providing an aerodynamic extension between an outer surface of said fan cone and an outer surface of a fan blade platform, wherein said annular wall is made of a first material that is a composite material and is provided on an inner surface of said rim with a ring made of a second material which is a metal material including titanium or a metal alloy based on titanium and aluminum and is suitable for radially retaining said fan blade platform. 2. A link part according to claim 1 , wherein said orifices are provided with metal inserts made of titanium or of metal alloy based on titanium. 3. A link part according to claim 1 , wherein said outer surface providing the aerodynamic extension is covered in a fabric of composite material for withstanding lightning or erosion. 4. A fan including at least one link part according to claim 1 . 5. A turbine engine including the fan according to claim 4 . 6. A link part for a turbine engine, the link part being mounted between a fan cone and a fan disk supporting fan blades, said link part comprising: an annular wall pierced by a plurality of orifices, each orifice for receiving a fastener member and terminated by a substantially perpendicular rim having an outer surface providing an aerodynamic extension between an outer surface of said fan cone and an outer surface of a fan blade platform, wherein said annular wall is made of a short-fiber composite material and is provided on an inner surface of said rim with a ring made of a long-fiber composite material that is different from the short-fiber composite material and is suitable for radially retaining said fan blade platform, wherein said outer surface providing the aerodynamic extension is covered in a fabric of composite material for withstanding lightning or erosion, and wherein the ring abuts the fan blade platform. 7. A link part according to claim 6 , wherein said orifices are provided with metal inserts made of titanium or of metal alloy based on titanium. 8. A fan including at least one link part according to claim 6 . 9. A turbine engine including a fan according to claim 8 . 10. A link part according to claim 6 , wherein said long-fiber composite material is of a type involving winding a yarn, a tape, or a woven or stitched preform of carbon, glass, or aramid fibers.
