IPC: F03D1/02
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To convert wind power energy into electric power energy, etc., in a wide range of wind velocity. SOLUTION: Plural sets of sail units 4, each of which consists of at least two plate-like stocks 4a, 4b, are radially mounted to the periphery of a rotary shaft 3 of a windmill at equal angles. The flow of a wind blowing from the front into between the stocks 4a, 4b, which is a laminal flow in the upstream zone, develops into a turbulent flow in the downstream zone, and the boundary between the laminar flow and the turbulent flow is moved to the upstream with increasing the wind velocity. Thus, the wind receiving surfaces of the stocks 4a, 4b of the plural sets of the sail units 4 are inclined respectively at different angles to each other and in the same direction as the plane of rotation in order that the rotation of the sail unit 4 is suppressed by the grown turbulent flow to produce the decelerative effect when the wind velocity exceeds a constant value.
