Abstract

An assembly (30) is provided for an aircraft propulsion system (20). This assembly (30) includes an open propulsor rotor (34) and an open guide vane structure (36). The open propulsor rotor (34) is configured to rotate about an axis (24). The open propulsor rotor (34) includes a plurality of open propulsor blades (42) arranged circumferentially about the axis (24) in a blade array. Each of the open propulsor blades (42) projects spanwise into an environment (22) external to the aircraft propulsion system (20) to a respective blade tip (46). The open propulsor blades (42) include a first span propulsor blade (42A) and a second span propulsor blade (42B). The first span propulsor blade (42A) has a first span length (48A). The second span propulsor blade (42B) has a second span length (48B) that is less than the first span length (48A). The open guide vane structure (36) is axially next to the open propulsor rotor (34).
