FIELD: engines and pumps.
SUBSTANCE: proposed rotor disk comprises, in fact, axial slots made along its edges to receive and lock vane roots with hooks on their rear ends. Note here that deformable zones are made at slot rear ends formed by cavities. Note also that said cavities are arranged in flanges jointing between-the-vanes surfaces.
EFFECT: decreased wear, longer life.
