Turbine engine including a steam system

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.
