Rotor blade arrangement of wind wheel for small wind-power plant, has rotor blades fastened over hub, where hub carries propeller cover at wind facing end, which effects wind concentration on rotor blades
摘要
<p>The rotor blade arrangement (1) has rotor blades (2) fastened over a hub (5). The hub carries a propeller cover (4) at the wind facing end, which effects a wind concentration on the rotor blades. The external radius of the rotor blade arrangement is about 3 meters and the largest radius of the circle of the propeller cover amounts to 0.8 meters, at which the rotor blades lie.</p>
