Patent attributes
A system for in situ cleaning of internal components of a gas turbine engine may generally include a plug assembly defining a fluid passageway that is configured to be installed within an access port of the engine such that the fluid passageway defines a flow path between inner and outer casings of the engine. The plug assembly may include an inner sleeve at least partially defining the fluid passageway and an outer sleeve configured to receive a portion of the inner sleeve. The system may also include a fluid conduit configured to be coupled between a fluid source positioned external to the gas turbine engine and an inlet end of the plug assembly for supplying a cleaning fluid to the plug assembly. The cleaning fluid may be directed through the fluid passageway and may then be expelled from the plug assembly into the interior of the gas turbine engine.
