1. A propulsion system for an aircraft comprising:
a core engine including a core flow path where air is compressed in a compressor section, communicated to a combustor section, mixed with a hydrogen based fuel and ignited to generate a high energy gas flow that is expanded through a turbine section;
a hydrogen fuel system configured to supply hydrogen fuel to the combustor through a fuel flow path;
a condenser arranged along the core flow path and configured to extract water from the high energy gas flow, the condenser including a plurality of spiral passages disposed in a collector, wherein the spiraling passages are configured to receive the high energy gas flow and generate a transverse pressure gradient to direct water out of the high energy gas flow toward the collector, and a plurality of cooling flow passages that extend axially along a condenser axis and each of the plurality of spiraling passages wrap around a corresponding one of the plurality of cooling flow passages; and
an evaporator arranged along the core flow path and configured to receive a portion of the water extracted by the condenser to generate a steam flow, wherein the steam flow is injected into the core flow path upstream of the turbine section.
