TURBINE ENGINE INCLUDING A STEAM SYSTEM

Abstract: a turbine engine for an aircraft includes a turbo-engine with a core air flow path, a fan having a fan shaft coupled to the turbo-engine to rotate the fan shaft, and a steam system. the core air flow path includes a plurality of core air flow path zones. a combustor is positioned in the core air flow path to combust fuel and to generate combustion gases. the steam system extracts water from combustion gases and vaporizes the water to generate steam. the steam system is fluidly coupled to a core air flow path to inject the steam into the core air flow path at a plurality of steam injection zones to add mass flow to the core air. each steam injection zone of the plurality of steam injection zones corresponds to a core air flow path zone of the plurality of core air flow path zones.
