ABSTRACT OF THE DISCLOSURE A subcircular type rotor is disclosed comprising an axial central hub, radial webs supported by the central hub and each including a mass localised at the outer end of the web which mass constitutes the major part of the total mass of the web, and a subcircular rim supported on the webs, wherein the radius of curvature of the sectors of the rim between each pair of consecutive webs is greater than the outer radius of the webs and the size of the localised masses is selected so that the centrifugal force that they exert when the rotor rotates counteracts the radial compressive force which the subcircular rim exerts on each web inwardly towards the hub when the rotor is stationary, In a rotor according to the present invention, the radial stresses exerted on each web may advantageously be reduced as compared to prior art rotors.
