Non-streamlined propeller e.g. unducted fan propeller, for turbomachine, has ring screwed on body of plate and placed on outer surface of rotor element by bearing, where plate has expanded end outwardly arranged on inner surface of element

摘要

The propeller has blades rotatably mounted around axes in radial housings (138) of an annular rotor element (136), where each blade is fixed on a plate (144). The plate has an expanded radial inner end (168) outwardly arranged on an inner surface of the rotor element by a bearing (152). A ring (150) is screwed on a cylindrical body (146) of the plate at exterior of the housing. The ring is placed on an outer surface (164) of the rotor element by another bearing (154). The plate and the ring are centered and rotatably guided by the bearings.
