OSTI ID:6463194
A wind-turbine having a horizontal shaft carrying the turbine blades, hinged in such a manner that a limited flapping movement is possible. The flap angle of the turbine blade is adjustable by means of the position of the piston of a double-acting pistoncylinder drive means. The two chambers of the piston-cylinder drive means are connected to one another over a regulatable throttle valve. A regulatable pump is coupled in parallel with the throttle valve and coacts with it to oscillate or lock the blades.
