Abstract
There is provided a method for cleaning the compressor of a gas turbine engine. The method comprises providing a fluid passage in the inlet case strut with a nozzle communicating with the fluid passage and the inlet gas path. The fluid passage has a fluid connector for connecting wash/rinse fluid under pressure to the fluid passage. The method further comprises motoring the gas turbine engine, and injecting, through the nozzle, the wash/rinse fluid into the inlet gas path to mix with an incoming flow of air and flow into compressor rotor blades of the compressor.
