Abstract

An assembly for an aircraft propulsion system includes an open propulsor rotor having variable geometry propulsor blades and an open guide vane/stator assembly having a plurality of guide vanes (stator blades) in a fixed position relative to the rotor and assembly. The geometry (e.g., pitch, camber, etc.) of the guide vanes can be manually adjusted by ground personnel but are incapable of adjustment during a flight mission (a flight). The open propulsor rotor is configured to rotate about an axis, and the guide vane assembly includes the plurality of guide vanes arranged circumferentially about the axis and is disposed axially next to and downstream of the propulsor rotor.
