Abstract: The twist morphing blade for wind turbine is a blade adapted for attachment to the hub of a wind turbine. The blade has a central shaft extending between the root and tip ends of the blade. A guide track is defined in the central shaft. A sliding mass is slidably disposed in the guide track and bears against a bias spring. A driven shaft is coaxially disposed around the sliding mass and bias spring and rotatably coupled to the sliding mass. Connecting rods extend between the driven shaft and root end of the blade and through active and passive ribs alternately spaced between the driven shaft and the root end of the blade. When incident wind rotates the rotor, centrifugal force linearly slides the mass, which rotates the driven shaft and the connecting rods to deflect the ribs, twist morphing the medial sections of the blade.
