A rotor driven for an axial flow gas turbine engine compressor is formed as a composite structure of inner and outer skins with a core therebetween and a set of tensile reinforcing rings each located in a respective groove of a corrugated outer surface of the drum. In the completed drum the drum body is preferably under compressive prestress while the reinforcing rings are under tensile prestress.
A drum for a compressor rotor having recess means for mounting rotor blades which comprises: an internal layer of material; an external layer of material; a core layer of material sandwiched between said internal and external layers of material, said external layer of material being formed with peripheral ridges and grooves; and tensile reinforcing rings positioned within said grooves of said external layer of material.
