Rotor for a wind power generator

摘要

A rotor according to a preferred embodiment of the invention has at least one blade arranged at a hub of the rotor, wherein the blade has a curvature between its leading edge and its trailing edge which curvature has a first convex surface and an opposite second concave surface, wherein the first surface is to be arranged against the direction of the wind striking the blades. The convex profile of the first surface and the concave profile of the opposite second surface are spaced by the thickness of the blade which is preferably constant. The hub is arranged at the rotational axis.

主权项

1. A rotor for a wind power generator having at least one blade rotatable around a rotational axis, which blade has a first surface between a leading edge and a trailing edge, which surface in perpendicular to the longitudinal axis of the blade has a convex profile having an apex line extending approximately in parallel to the longitudinal axis of the blade, wherein at the apex line surface sections of the first surface adjoin in an angle and the opposite second surface is concave in that surface sections of the second surface adjoin in an angle along an apex line of the second surface in parallel to the apex line of the first surface, wherein the surface section of the blade extending between the apex line of the first surface and the trailing edge has a third buckling edge along which a planar surface section adjoining at the trailing edge is bent by about 5°.
