Abstract

An assembly for an aircraft propulsion system (20) includes an open propulsor rotor (34), a housing structure (54), and a turbine engine core (76). The open propulsor rotor (34) includes a plurality of open propulsor blades (42) arranged circumferentially around an axis (24). Each of the plurality of open propulsor blades (42) projects radially out into an environment (22) external to the aircraft propulsion system (20). The housing structure (54) includes an engine case assembly (106) and a nacelle (108). The nacelle (108) forms at least a portion of an exterior flow boundary (56) for the aircraft propulsion system (20). The nacelle (108) forms a guide vane structure receptacle (136) at the exterior flow boundary (56). The nacelle (108) further includes a nacelle interior skeletal structure (140) disposed at the guide vane structure receptacle (136). The turbine engine core (76) is housed within the engine case assembly (106). The turbine engine core (76) is configured to drive rotation of the open propulsor rotor (34) about the axis (24).
