PROBLEM TO BE SOLVED: To provide a method and device for jetting water into a gas turbine engine 10 by a nozzle 40, wherein the gas turbine engine is furnished with an air circuit 80, water circuit 82, and a revolver 100 to reduce erosion inside the nozzle. SOLUTION: The air circuit is formed with a first conduit 84 extending along the nozzle, while the water circuit is configured with a second conduit 86 extending along the nozzle and positioned inside in the radial direction from the first conduit. The two circuits are put in communications hydraulically with a discharge opening 90. Adjacent to the discharge opening, air revolver is installed to spray the air into the atomized water emitted from the water circuit and promote the water evaporation for lowering the engine operating temperature.
