Abstract: A turbine engine for an aircraft includes a fan that rotates to generate a volume of air, a core turbine engine, a nacelle, and a steam system. The core turbine engine includes a combustor that generates combustion gases, and a turbine including a shaft. The combustor and the turbine define a core air flowpath. The fan is drivingly coupled to the shaft. The nacelle circumferentially surrounds the fan and defines a bypass airflow passage between the nacelle and the core turbine engine. The volume of air flows into the bypass airflow passage as bypass air and flows into the core air flowpath as core air. The steam system extracts water from the combustion gases, vaporizes the water to generate steam, and injects the steam into the core air flowpath to add mass flow to the core air. A bypass ratio of the turbine engine is greater than 18:1.

Abstract: A turbine engine for an aircraft including a turbo-engine, a fan having a fan shaft coupled to the turbo-engine, and a steam system. The steam system is fluidly coupled to a core air flow path at a plurality of steam injection locations to selectively inject steam into the core air flow path at each of the plurality of steam injection locations, using a steam flow control valve. The plurality of steam injection locations include (i) an upstream steam injection location located to inject steam into the core air flow path at a primary combustion zone of a combustor or upstream thereof and (ii) a downstream steam injection location located to inject steam into the core air flow path downstream of the primary combustion zone.
