Abstract

A turbofan gas turbine engine for use in an aircraft includes a fan, an engine core, and a cleaning system. The fan and engine core cooperate to provide thrust for an aircraft when in use but may suffer performance degradation when dirty. The cleaning system is configured to conduct a cleaning agent from a supply into the turbofan gas turbine engine to clean the turbofan gas turbine engine.
