Abstract

Washing of the gas turbine engine, during operation of the gas turbine engine, comprises a washing phase that consists in spraying a detergent liquid substance towards the inlet of the compressor of the engine; the mass flow of the detergent liquid substance to be sprayed is set so that the liquid-to-gas ratio at the inlet of the compressor is more than 1% and less than 5% with reference to the rated mass flow of the compressor; the washing phase comprises a first sub-phase during which the flow of the detergent liquid substance is increased gradually and a second sub-phase during which the flow of the detergent liquid substance is maintained constant.
