A wind powered generating device 1 has a one piece symmetrical aerofoil 2, which is driven by the wind in a reciprocating motion. The foil 2 is pivoted at mid chord and has end stops 3 to limit the pitch angle (angle of attack). A piston and cylinder arrangement 7 is used to reverse the pitch at each end of the stroke, and also serves to damp the reversing movement. The end stops 3 can be adjusted by actuators 8 according to the operating conditions. The device may be pivotally mounted so that it automatically turns into the wind, and may be installed on a floating platform |
