First Claim
Patent Images
1. A gas turbine engine comprising:
- a fan spinner;
a fan disk; and
an elastic vibration damper disposed within an interior of the fan spinner and operatively interposing the fan spinner and the fan disk;
wherein the elastic vibration damper contacts the fan spinner forward of an aft edge of the fan spinner and is squeezed generally radially between the fan spinner and the fan disk.

Abstract
Dampers for fan spinners of aircraft engines are disclosed. An example fan module for a gas turbine engine may include a fan disk; fan blades mounted to the fan disk and extending radially therefrom; a fan spinner operatively coupled to the fan disk at an axially upstream position; and/or one or more elastic vibration dampers operatively interposing the fan spinner and the fan disk. The elastic vibration dampers may be disposed circumferentially around an interface between the fan spinner and the fan disk and may be compressed axially and/or radially.
