摘要

A bearing compartment for a gas turbine engine comprises a housing that surrounds an engine axis of rotation and has an inner surface and an outer surface spaced radially outward of the inner surface. The housing defines an open volume for a lubricant and includes a bearing seat to seat a bearing for rotation about the engine axis of rotation. The housing includes at least one cooling protuberance extending into the open volume.
