Kind Code:
A1
Abstract:
A turbine (3) is provided with a boss part (2) rotatably driven by an electric motor, and a plurality of rotating blades (1) that protrude from the boss part (2) in a radial formation in the radial direction of a rotating shaft (4) of the electric motor and generate an air flow in the axial direction of the rotating shaft (4), each of the the rotating blades (1) having an S-shaped radial-direction cross section of which the inner peripheral side is convex relative to the air flow and the outer peripheral side is concave relative to the air flow, the curvature radius values of the concave portions of the rotating blades (1) having a distribution that gradually decreases from blade leading edges (1b) toward blade trailing edges (1c), and the rate of gradual decrease being smaller toward the blade trailing edges (1c).
