Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F | IPC F

Claim 0:
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 water recovery system including a condenser arranged along the core flow path that is configured to extract water from the high energy gas flow;
a water monitoring system including at least one sensor disposed downstream of the condenser and a controller programed to determine a condition of water and generate a prompt based on information communicated from the at least one sensor; and
an evaporator in thermal communication with a core engine heat source and configured to generate a steam flow from a portion of water extracted by the condenser, wherein the steam flow is injected into the core flow path upstream of the turbine section.
