Abstract

A fairing assembly includes an outer wall, a first side wall, a second side wall, and a saddle. The first side wall and the second side wall extend from opposing sides of the outer wall. Together the first side wall, the second side wall, and the outer wall form a cavity within the fairing assembly. The saddle is positioned within the cavity and extends between the first side wall and the second side wall. The saddle has a first rib adapted to connect to the first side wall and a second rib adapted to connect to the second side wall. The first rib and the second rib connect together at a central hub.

First claim

The invention claimed is:

1. A fairing assembly comprising:
an outer wall;
a first side wall and a second side wall extending from opposing sides of the outer wall, wherein together the first side wall, the second side wall, and the outer wall form a cavity within the fairing assembly; and
a saddle disposed within the cavity and extending between the first side wall and the second side wall, wherein the saddle has a first linkage adapted to connect to the first side wall and a second linkage adapted to connect to the second side wall, and wherein the first linkage and the second linkage extend from a central hub.

2. The fairing assembly of claim 1 , wherein the central hub, the first linkage, and the second linkage have one or more openings therein.

3. The fairing assembly of claim 2 , further comprising:
a hub having one or more tabs extending therefrom, wherein the one or more tabs have an aperture therethrough; and
a pin received in the aperture and extending through the one or more tabs and an aperture of the central hub to mount the fairing assembly to the hub;
wherein the one or more openings in the saddle are adapted to allow the one or more tabs to extend into the cavity within the fairing assembly.

4. The fairing assembly of claim 3 , wherein the first side wall and the second side wall have one or more openings therein that are adapted to receive the one or more tabs.

5. The fairing assembly of claim 3 , further comprising one or more bushings disposed about the pin adjacent the one or more tabs.

6. The fairing assembly of claim 1 , wherein the saddle comprises a single structure that extends from a forward portion of the cavity to a rear portion of the cavity, and wherein the saddle is integral to and co-molded with the first side wall and the second side wall.

7. The fairing assembly of claim 1 , wherein the saddle comprises a first saddle and a second saddle, wherein the first saddle is spaced at a distance from the second saddle, and wherein the first and second saddles comprise separately formed details that are secondarily bonded to the first side wall and the second side wall.

8. The fairing assembly of claim 1 , wherein surfaces of the saddle include features that extend along outer surfaces of first and second linkages, which facilitate bonding of the saddle to the first side wall and the second side wall.

9. A fan assembly comprising:
a hub having one or more tabs extending therefrom, wherein the one or more tabs have an aperture extending therethrough;
a pin received in the aperture and extending through the one or more tabs; and
a fairing assembly mounted to the hub, the fairing assembly comprising:
an outer wall;
a first side wall and a second side wall extending from opposing sides of the outer wall, wherein the first side wall, the second side wall, and the outer wall together form a cavity within the fairing assembly; and
one or more saddles that are adapted to receive both the one or more tabs and the pin to mount the fairing assembly to the hub, wherein one or more openings in each of the one or more saddles are adapted to allow the one or more tabs to extend into the cavity within the fairing assembly, and wherein the one or more saddles are disposed within the cavity and extend between the first side wall and the second side wall, and wherein each of the one or more saddles has a first linkage adapted to connect to the first side wall and a second linkage adapted to connect to the second side wall, and wherein the first linkage and the second linkage extend from a central hub.

10. The assembly of claim 9 , further comprising a plurality of fan blades mounted to the hub, wherein the fairing assembly is disposed between adjacent fan blades adjacent the hub.

11. The fan assembly of claim 9 , wherein the first side wall and the second side wall have one or more openings therein that are adapted to receive the one or more tabs.

12. The fan assembly of claim 9 , wherein the one or more saddles comprise a single structure that extends from a forward portion of the cavity to a rear portion of the cavity, and wherein the one or more saddles are integral to and co-molded with the first side wall and the second side wall.

13. The fan assembly of claim 9 , wherein the one or more saddles comprise a first saddle and a second saddle, wherein the first saddle is spaced at a distance from the second saddle, and wherein the first and second saddles comprise separately formed details that are secondarily bonded to the first side wall and the second side wall.

14. The fan assembly of claim 13 , wherein and the second saddles include features that extend along outer surfaces thereof which facilitate bonding of the first saddle and the second saddle to the first side wall and the second side wall.

15. The fan assembly of claim 9 , wherein the one or more saddles include features that extend along outer surfaces thereof which facilitate bonding of the one or more saddles to the first side wall and the second side wall.

16. A gas turbine engine comprising:
a fan hub having one or more tabs extending therefrom, wherein the one or more tabs have an aperture extending therethrough;
a pin received in the aperture and extending through the one or more tabs; and
a fairing assembly mounted to the fan hub, the fairing assembly comprising:
an outer wall;
a first side wall and a second side wall extending from opposing sides of the outer wall, wherein the first side wall, the second side wall, and the outer wall together form a cavity within the fairing assembly; and
one or more saddles that are adapted to receive both the one or more tabs and the pin to mount the fairing assembly to the hub, wherein one or more openings in each of the one or more saddles are adapted to receive the one or more tabs, and wherein the one or more saddles are disposed within the cavity and extend between the first side wall and the second side wall, and wherein each of the one or more saddles has a first linkage adapted to connect to the first side wall and a second linkage adapted to connect to the second side wall, and wherein the first linkage and the second linkage extend from a central hub.

17. The gas turbine engine of claim 16 , further comprising a plurality of fan blades mounted to the hub, wherein the fairing assembly is disposed between adjacent fan blades adjacent the hub.
