1. An engine system, comprising:
an open propulsor rotor;
an inlet duct upstream of and fluidly coupled in parallel with a core inlet and a bypass inlet;
an engine core assembly configured to drive rotation of the open propulsor rotor, the engine core assembly including a core flowpath, a compressor section, a combustor section and a turbine section, and the core flowpath extending through the compressor section, the combustor section and the turbine section from the core inlet into the core flowpath to an exhaust from the core flowpath;
a bypass flowpath bypassing the engine core assembly and extending along a length of the core engine assembly;
a condenser configured to exchange heat energy between combustion products flowing within the core flowpath downstream of the combustor section and bypass air flowing within the bypass flowpath; and
a housing, wherein the engine core assembly and the bypass flowpath are disposed in the housing, the bypass flowpath extending from the bypass inlet, internally through the engine system, to a bypass exhaust, the housing extending along the length of the core engine assembly, and the open propulsor rotor is configured to propel additional air outside of and along the housing to provide thrust.
