A rotary drum of an axial compressor having a web made of composite material has an upstream flange for fastening the fan, a segment having a sealing flange upstream, a segment with a groove adapted to receive the bases of the vane of a first row of vanes, a segment with a groove adapted to receive the bases of the vane of a second row of vanes, and a segment with a groove adapted to receive the bases of the vane of a third row of vanes. These segments are made of metallic material mostly for reasons of mechanical resistance to the centrifugal forces. The segments are connected to each other with web segments made of composite material. The ends of the metallic segments have a dovetail-shaped section in a longitudinal plane that is able to ensure a positive connection with the composite material.
