Abstract
A turbine engine assembly generates an exhaust gas flow that is divided into a first exhaust gas flow and a second exhaust gas flow. A desiccation system transfers water vapor from the first exhaust gas flow into the second exhaust gas flow. A condenser extracts water from the second exhaust gas flow and an evaporator system uses thermal energy from the exhaust gas flow to generate a steam flow from at least a portion of water that is extracted by the condenser for injection into the core flow path.
Claims16
A turbine engine assembly comprising:
- a compressor section where an inlet airflow is compressed;
- a combustor section where the compressed inlet airflow is mixed with fuel and ignited to generate an exhaust gas flow that is communicated through a core flow path;
- a turbine section through which the exhaust gas flow expands to generate a mechanical power output, wherein the exhaust gas flow is divided into a first exhaust gas flow and a second exhaust gas flow, and the first exhaust gas flow is exhausted through a first nozzle and the second exhaust gas flow is exhausted through a second nozzle;
- a desiccation system where water vapor from the first exhaust gas flow is concentrated and released into the second exhaust gas flow;
- a condenser where water from the second exhaust gas flow is extracted;
- and
- an evaporator system where thermal energy from the exhaust gas flow is utilized to generate a steam flow from at least a portion of water extracted by the condenser for injection into the core flow path.

An aircraft propulsion system comprising:
- a propulsor section;
- a core engine that defines a core flow path where an inlet airflow is compressed, mixed with fuel, and ignited to generate an exhaust gas flow that generates shaft power to drive the propulsor section, wherein the exhaust gas flow is divided into a first exhaust gas flow and a second exhaust gas flow, and the first exhaust gas flow is exhausted through a first nozzle and the second exhaust gas flow is exhausted through a second nozzle;
- a desiccation system where a desiccant material absorbs water vapor from the first exhaust gas flow and releases the absorbed water vapor into the second exhaust gas flow;
- a condenser configured for extracting water from the second exhaust gas flow;
- an evaporator system configured to use thermal energy from the exhaust gas flow to vaporize water into a steam flow from at least a portion of water extracted by the condenser for injection into the core flow path.
