Abstract
A fan assembly for use in a gas turbine engine of an aircraft includes a fan disk having a number of fan blades and a windage shield coupled to the fan disk to move therewith. The fan assembly supplies air for use in the engine. The windage shield rotates with the fan disk during operation of the gas turbine engine and directs air supplied by the fan blade.
Claims18
A gas turbine engine comprising
- a fan disk arranged to hold a plurality of fan blades for rotation about a central axis of the gas turbine engine, the fan disk being formed to include an axial wall and a pilot receiver extending axially from the axial wall,
- a windage shield arranged to guide incoming air provided by the fan blades through the gas turbine engine, the windage shield coupled to the fan disk to move therewith, and
- a pilot unit coupled to the windage shield to move therewith and arranged to extend downwardly and engage the pilot receiver, the pilot unit including a pilot mount appended to the windage shield and arranged to extend toward the pilot receiver, a pilot anchor located in spaced-apart radial relation to the pilot mount and arranged to engage the pilot receiver and axial wall of the fan disk, and a bias link arranged to extend between and interconnect the pilot mount and the pilot anchor, the bias link elastically deformed to encourage the pilot anchor toward the pilot receiver and axial wall of the fan disk to maintain alignment of the windage shield with the fan disk during operation of the gas turbine engine.
A process of coupling a first component to a second component in a gas turbine engine, the process comprising the steps of
- arranging a first component and a second component along a central axis of the gas turbine engine,
- contacting a first portion of the second component against the first component to align the second component relative to the first component,
- biasing a second portion of the second component toward the first component to elastically deform a third portion of the second component coupled between the first and second portions to force the first portion against the first component, and
- retaining the second component on the first component such that contact between the first portion of the second component and the first component is maintained as radial loads placed on the second component vary during operation of the gas turbine engine.
