Patent attributes
A bearing damper assembly for a bearing compartment of a gas turbine engine includes a squirrel cage, a bearing support, an outer sleeve, and an inner sleeve. The bearing support is disposed radially outward from a portion of the squirrel cage. The outer sleeve extends axially from the bearing support. The inner sleeve is attached to the squirrel cage and is disposed radially inward from the outer sleeve. An outward surface of the inner sleeve has a first contoured portion having a first axially extending contour and an inner surface of the outer sleeve has a second contoured portion having a second axially extending contour. The outward surface of the inner sleeve and the inner surface of the outer sleeve define a gap extending between the first contoured portion and the second contoured portion. The gap forms a fluid damper.
