Abstract
A method for enables a gas turbine engine to be assembled. The method comprises forming at least one substantially elliptically-shaped opening within a flange extending from a fan disk, inserting a fastener including a first body portion, a second body portion, and an anti-rotation stop extending therebetween, at least partially through the at least one flange opening, and coupling the fastener to the flange such that the fastener stop is positioned within the at least one flange opening.
Claims19
A method for assembling a gas turbine engine, said method comprising:
- forming at least one substantially elliptically-shaped opening within a flange extending from a fan disk;
- inserting a fastener at least partially through the at least one flange opening, wherein the fastener includes a first body portion, a second body portion;
- and
- coupling the fastener to the flange such that a fastener stop is positioned within the at least one flange opening.
A fan assembly for a gas turbine engine, said fan assembly comprising:
- a fan disk comprising a plurality of hubs coupled to a disk rim by a plurality of webs;
- and
- an annular forward extension comprising a flange, said forward extension extending forwardly from an upstream most of said webs, said flange comprising a plurality of circumferentially spaced openings extending therethrough, at least one of said openings being substantially elliptically-shaped.
A fan assembly comprising:
- a fan disk comprising an annular flange comprising at least one opening extending therethrough;
- at least one fastener comprising a first body portion, a second body portion, and an anti-rotation stop extending therebetween;
- and
- a spinner coupled to said fan disk by said at least one fastener, said fastener stop facilitates aligning said at least one fastener with respect to said flange.
