Abstract
A method for operating a gas turbine engine including a high pressure compressor, a variable inlet guide vane assembly and a water injection apparatus for injecting water into a flow of the engine is provided. The method comprises transmitting engine operating parameters including a temperature of the gas flow at an outlet of the high pressure compressor, T3, to an engine controller, using the controller to regulate a flow of water injected into the gas flow and to adjust a relative position of the inlet guide vane assembly until engine full power is about reached as determined by a pre-defined T3 operating parameter limit, and adjusting the controller to then facilitate operation of the engine with an increased output without exceeding the pre-defined T3 operating parameter limit.
