Abstract
A sealing and retention device for the blades of a rotor which engage with axial pin settings of the rotor wherein the device includes, in a first embodiment, a flange in the shape of a circular collar which engages the rotor and a locking ring which engages the blades and the flange wherein the locking ring has a conical portion which engages a first protuberance portion of the blades such that upon centrifugal sliding of the locking ring in a radially outward direction, the locking ring is axially displaced toward the flange. The device may also include a conical crest located on the rotor and the flange may have a conical surface for engaging the conical crest of the rotor.
