A compressor wash nozzle integrated in an inlet case strut of a turbine engine is described. A fluid passage and a nozzle are defined in the inlet case strut for delivering a wash/rinse fluid into the inlet gas path of the engine. A fluid connector communicates with the fluid passage and is positioned exteriorly of the inlet gas strut and adapted for receiving pressurized wash/rinse fluid for injection through the nozzle into gases flowing in the inlet gas path and in the direction of the compressor for washing and/or rinsing the blades of the compressor.

1. A compressor wash nozzle arrangement for a gas turbine engine having an inlet case strut extending transversally across an inlet gas path upstream of a compressor section of the gas turbine engine, the compressor wash nozzle arrangement comprising a fluid passage extending through the inlet case strut, a nozzle integrated to said inlet case strut and in fluid flow communication with said fluid passage and disposed for discharging a pressurized wash/rinse fluid into incoming air flowing through the inlet gas path, a fluid connector communicating with said fluid passage and positioned exteriorly of said inlet case strut and adapted for connection with a source of pressurized wash/rinse fluid for injection through said nozzle into gases flowing though the inlet gas path in the direction of the compressor section. 2. A compressor wash nozzle arrangement as claimed in claim 1, wherein said nozzle is provided on a trailing edge of said inlet case strut. 3. A compressor wash nozzle arrangement as claimed in claim 2, wherein said nozzle is a spray nozzle which is oriented to spray said wash/rinse fluid in the direction of a first stage of rotor blades of the compressor section. 4. A compressor wash nozzle arrangement as claimed in claim 1, wherein said fluid connector is a hose connector accessible from outside of the gas turbine engine. 5. A compressor wash nozzle arrangement as claimed in claim 1, wherein said fluid passage is a conduit drilled or cast in the inlet case strut. 6. A compressor wash nozzle arrangement as claimed in claim 5, wherein said nozzle is a drill hole in communication with said fluid conduit. 7. A gas turbine engine comprising a compressor wash nozzle arrangement as claimed in claim 1, wherein the gas turbine engine is one of a turbo shaft, turboprop or turbofan engine.
