Cleaning solvent is sprayed about the periphery of the air intake of a gas turbine engine in that area of the intake where the air speed is turbulent and relatively slow. The pattern of spray is created by a plurality of nozzles uniformly spaced about the periphery of the air intake. The nozzles each have an arm bent at an angle of approximately 30°and mounted to create a spray pattern of a fan shape at an angle of 90°respecting the exit aperture of the nozzle. The spray cloud thus created in the area of low speed relatively turbulent air before the compressor of the engine creates a uniform intake of cleaning fluid into the engine when the engine is operated at or near full speed and at or near full load. The 90°fan shape pattern at the nozzle aperture narrows to 60°when the engine reaches operating speed and load.

Apparatus for cleaning a compressor of a gas turbine engine said apparatus comprising: means for operating the compressor at or near full speed and load; means for pressurizing a cleaning solvent; a plurality of nozzle means connected to said pressurizing means for receiving said cleaning solvent; each of said nozzle means including an arm, said arm extending outwardly to a point, a bend in said arm at said point at an angle of approximately 30°with respect to said arm, and an aperture located remote from said point along said arm and means for mounting each of said nozzle means, said mounting means being located in proximity to the air intake of said compressor so that the apertures of each of said nozzle means extends in proximity to the area of low and turbulent air velocity in said air intake.
