<p>Device for converting wind flow energy into mechanical energy, having a base construction (4) and a rotor (8) having a number of rotor blades (20; 20a) which are connected to an annular rotary support (18) and extend essentially in a plane through the axis of rotation (14) of the support. The wind-braking area of the rotor (8) is adjustable. Each rotor blade (20; 20a) or a part thereof is hingedly connected to the rotor support (18) for setting the rotor blade or part thereof in a predetermined lengthwise orientation at a predetermined distance relative to the axis of rotation (14) of the support by moving the rotor blade or part thereof in a plane through the axis of rotation. The rotor blades (20; 20a) may be directly hingeably connected to the rotor support (18), or by means of an arm assembly (17; 22; 24). The rotor blades are made up of a number of elongated parts (74, 76, 78; 92) for varying the effective length of the blades.</p> |
