Abstract
An orifice plate assembly for a gas turbine engine that facilitates extending a useful life of bearing assemblies within the gas turbine engine is described. Each orifice plate assembly is coupled in flow communication with an engine air source, and includes a first body portion and a second body portion. The first body portion includes a channel and a flow opening. The channel is sized to receive the second body portion, such that the second body portion may slide with respect to the first body portion. The orifice plate assembly is adjustable after engine shutdown to regulate bearing loading.
