The invention relates to a device for cleaning a gas turbine engine (2), in particular for cleaning an engine of a cleaning turbine fan type. The invention also relates to a method for cleaning the engine. The device comprises a plurality of spray nozzles (31, 33, 35); and the spray nozzles (31, 33, 35) are deployed at the upstream of a fan (25) of the engine (2) and at an air inlet (20) of the engine (2) so that cleaning liquid in gas flow is atomized. According to the invention, a first spray nozzle (31) is deployed at some position, so that the cleaning liquid emitted from the first spray nozzle (31) approximately impacts the surface of a blade (40) on a pressure side (53); a second spray nozzle (35) is deployed at some position, so that the cleaning liquid emitted from the second spray nozzle (35) approximately impacts the surface of the blade (40) on a suction side (54); and a third spray nozzle (33) is deployed at some position, so that the cleaning liquid emitted form the third spray nozzle (33) approximately passes through the blade (40) and enters an inlet (23) of a core engine (203). Consequently, the invention can effectively remove different types of scale found on the fan and the core engine compressor of the turbofan engine. |
