  • Annular gasket disposed at one axial extremity of a rotor and covering blade feet
    Patent number: 5330324
    Abstract: An annular gasket includes, at least partially conically shaped portion and is supported on a rotor via three bearing surfaces. The conical shape makes it possible to reject the center of gravity of the sections of the rotor which provokes substantial rotational movement when centrifugal forces exist and allows for an improved imperviousness via the internal and external bearings. This invention is applicable for the rotors of aircraft engines provided with axial broachings in which blade feet are able to slide.
