A method is provided for operating a gas turbine engine that includes a high pressure compressor and a water injection apparatus for injecting water into a flow of the engine upstream from the high pressure compressor. The method includes the steps of operating the engine without injecting water into the gas flow of the engine, injecting water at a first flow rate into the gas flow for power augmentation once engine full power is about reached, and injecting water into the engine at an increased second flow rate for evaporative cooling of engine components downstream from the high pressure compressor.

1. A method for operating a gas turbine engine including a high pressure compressor and a water injection apparatus for injecting water into a flow of the engine upstream from the high pressure compressor, said method comprising the steps of:operating the engine without injecting water into the gas flow of the engine; injecting water into the gas flow at a first flow rate for power augmentation once engine full power is about reached; and injecting water at an increased second flow rate into the engine to evaporative cool engine components downstream from the high pressure compressor; wherein said method further includes the step of injecting water through a circumferential manifold having a plurality of alternating radially-inward extending long and short nozzles, each of said short nozzles being positioned substantially in-between two long nozzles.
