Wind-driven generating plant comprising at least one blade rotating about a rotation axis

A wind-driven generating plant comprising:

• a support means;
• a rotor assembly having a pair of members, at least one of which is a blade having an airfoil cross-section, said rotor assembly having a rotor assembly rotational axis about which said assembly rotates, each of said members lying at an angle in a range of approximately 40.degree.-80.degree. to the rotor assembly rotational axis;
• a rotor hub mounted on said support means for rotation about a vertical axis, said hub receiving said rotor assembly for rotation about said rotor assembly rotational axis and for orienting said axis at an angle in a range of 30.degree.-70.degree. to the horizontal, said hub having energy transmission means coupled to said rotor assembly;
• a pylon mounted on said rotor assembly and extending along said rotor assembly rotational axis;
• and
• guy members extending between said rotor assembly members and pylon, said guy members being fixed to the blade eccentrically with respect to the blade center of gravity for altering the angle of incidence of said blade.
