  • ROTORS FOR EXTRACTING ENERGY FROM WIND AND HYDROKINETIC SOURCES
    Publication number: 20150192105
    Abstract: Rotors for devices such as wind turbines have one or more blades that each include a first airfoil, and a second airfoil positioned proximate the first airfoil so that the first and second airfoils interact aerodynamically during rotation of the rotor. The first airfoil can be configured to pivot so that its angle of attack remains approximately zero.
