Abstract

An aircraft propulsion system includes an open propulsor rotor, an open guide vane structure, a turbine engine and a heat exchanger. The open guide vane structure includes a plurality of open guide vanes. The turbine engine is configured to drive rotation of the open propulsor rotor. The turbine engine includes a flowpath, a compressor section, a combustor section and a turbine section. The flowpath extends through the compressor section, the combustor section and the turbine section from a flowpath inlet to a flowpath exhaust. The flowpath inlet is disposed axially downstream of the open propulsor rotor and is fluidly coupled to an external environment. The heat exchanger is disposed radially outboard of the flowpath. At least a portion of the heat exchanger is disposed axially between the flowpath inlet and the open guide vanes. The heat exchanger is configured to transfer heat energy between air and a liquid working fluid.
