Abstract
An assembly is provided for an aircraft. This assembly includes an open propulsor rotor, an engine core and a geartrain. The open propulsor rotor is configured to rotate about an axis. The engine core includes a flowpath, a compressor section, a combustor section, a turbine section and a rotating structure. The flowpath extends through the compressor section, the combustor section and the turbine section from an inlet into the flowpath to an exhaust from the flowpath. The rotating structure includes a compressor rotor in the compressor section and a turbine rotor in the turbine section. The rotating structure is configured to rotate about the axis and drive rotation of the open propulsor rotor. The geartrain is disposed axially between and operatively couples the rotating structure and the open propulsor rotor. The geartrain includes a star gear system and a planetary gear system.
