Claim Text:
1. An apparatus for cleaning gas turbine engines, comprising: means for pressurizing a wash fluid, wherein said means comprises a low-pressure fluid delivery system; means for incorporating additives and/or detergents into the wash fluid; and a manifold and injection nozzle assembly, having a plurality of nozzles mounted on a moveable manifold that is fluidly connected to a source of wash fluid, the manifold positionable directly in front of an air inlet of a gas turbine engine for delivering the wash fluid into the air inlet of the gas turbine engine and connectable to the gas turbine engine, wherein the manifold and injection nozzle assembly is configured to deliver the wash fluid in at least one finely divided spray, with the wash fluid at each nozzle at a corresponding pressure of about 200 psi to about 725 psi and a total delivery rate through all of the nozzles of about 1 gallon per minute to about 50 gallons per minute, and wherein at least one of the nozzles has a first configuration that produces a first spray as to droplet size, flowrate, and dispersion spray pattern, and wherein at least one other of the nozzles has a second configuration, different from the first configuration, that produces a second spray, different from the first spray, as to droplet size, flowrate, and dispersion spray pattern.
