FIELD: machine building. ^ SUBSTANCE: multitude of blades are assembled on rotor forming blade wheel rotating around main axle of rotor. Each blade has a setting area. The rotor has main slots and auxiliary slots. Each main slot receives the setting area of the blade. The main and auxiliary slots can change their dimensions at rotation of the blade wheel because of centrifugal forces and heat effects caused with rotation. Changed dimensions exert pressure onto the setting area of the blade and maintain it inside the main slot. ^ EFFECT: change of dimensions at rotation of blade wheel due to centrifugal forces and heat effects caused with rotation. ^ 20 cl, 6 dwg |
