Nose cone for an airplane turbine engine with integrated balancing ring

摘要

The fan (1) has an annular balancing flange (34) coupled in rotation with a fan disk (4) along a longitudinal rotational axis (2), and including weight fixation holes (24) spaced circumferentially from one another. Balancing weights i.e. balancing screws (26), are fixed on the flange by the holes. The flange is arranged inside an inlet cone (20) in a manner that the holes are isolated from a jet (22) of a turbomachine i.e. jet engine, of an aircraft. A blade retaining ring (16) axially retains fan blades (6) with respect to the disk. The ring and the flange are formed of a single piece.
