摘要 |
The present invention relates to an aircraft turbomachine fan (1) comprising a turbomachine inlet cone (20) that has an exterior surface (19) intended to be closely followed by a flow section (22) of the turbomachine, an annular balancing flange (34) that rotates as one with a fan disk (4) about an axis of rotation (2) and is equipped with a plurality of weight-fixing holes (24), the fan also comprising one or more balancing weights (26) mounted fixedly on said annular balancing flange. Furthermore, the annular balancing flange (34) is positioned inside the inlet cone (20) in such a way that its weight-fixing holes (24) are isolated from the flow section (22). According to the invention, the flange (34) is produced as a single piece with a fan blade retaining ring (16). |
