Axial flow angled condenser arrangement for an aircraft propulsion system

A water recovery system for an aircraft propulsion system comprising:

• an exhaust duct assembly comprising a central portion turning an exhaust gas flow radially outward through a plurality of radial struts into a corresponding one of a plurality of splitters configured to turn the exhaust gas flow axially rearward;
• a plurality of condenser pairs where water is condensed from an exhaust gas flow received through a corresponding one of a plurality of the splitters, wherein each of the condenser pairs are angled relative to each other and the corresponding one of the plurality of exhaust ducts and a cooling airflow is communicated through each condenser into a space between corresponding ones of the condenser pairs;
• a plurality of water separators where water from corresponding ones of the plurality of condenser pairs is separated from the exhaust gas flow;
• an evaporator where water from the plurality of water separators is transformed into a steam flow and communicated to a combustor, wherein the evaporator comprises a plurality of evaporators disposed within a corresponding one of the plurality of splitters;
• and
• a plurality of superheaters where steam flow is further heated.

A method of operating an aircraft propulsion system comprising:

• generating an exhaust gas flow with a core engine comprising a compressor, combustor, and turbine section;
• coupling a propulsor to a power turbine configured to be driven by expansion of the exhaust gas flow about a propulsor axis by the core engine;
• communicating the exhaust gas flow through an exhaust duct assembly comprising a central portion turning an exhaust gas flow radially outward through a plurality of radial struts into a corresponding one of a plurality of splitters configured to turn the exhaust gas flow axially rearward;
• condensing water in a plurality of condensers pairs wherein each of the condenser pairs are angled relative to each other and a corresponding one of a plurality of splitters and each condenser of the plurality of condenser pairs comprises an outward facing side in flow communication with a cooling air flow and an inward facing side through which the cooling air flow is exhausted;
• separating water from the exhaust gas flow in one of a plurality of water separators;
• generating a steam flow from water extracted from the exhaust gas flow in an evaporator;
• and
• heating the steam flow from the evaporator in a superheater disposed within a corresponding one of the plurality of exhaust ducts.
