1. A turbine engine assembly comprising:
a core engine generating an exhaust gas flow communicated through an exhaust gas flow path;
a condenser where water is extracted from the exhaust gas flow;
an evaporator disposed within an exhaust gas flow path where heat is input into the water extracted by the condenser, without superheat to generate a first steam flow;
a steam turbine where the first steam flow is expanded and cooled; and
a superheater disposed within the exhaust gas flow path such that a flow of exhaust gas through the superheater is parallel to a flow of exhaust gas flow through the evaporator, wherein all of the first steam flow exhausted from the steam turbine is heated in the superheater to generate a second steam flow, wherein the second steam flow is injected into a core flow path of the core engine.
