Abstract
A rotor including a circumferential groove in which blade roots are retained. A locking means between two of the blades includes a part in the groove engaging the groove walls, and a retaining element movable radially of the rotor disk as well as rotatable about an axis lying along a radius of the disk. Tabs projecting radially outwardly from the retaining element are accommodated by a slot between the platforms of two rotor blades, when the retaining element is in one angular position. When the retaining element is rotated to another angular position, the tabs are held beneath the platforms of the two adjacent blades, and the inner end of the retaining element enters a recess in the bottom of the circumferential groove. Retaining slots may be provided in the bottom surfaces of the platforms for accommodating the tabs, and a spring may be provided to urge the retaining element radially outwardly.
