A gas turbine engine is disclosed in which water is used to cool the turbine. The water is turned to steam in the hot turbine; is super-heated, and then injected into the combustor to aid in the gasification of the fuel, to reduce the flame temperature and improve emissions, as well as increasing the specific output of the engine.
