초록 ▼

This invention relates to a flexible tethered wind turbine useful, among other things, for generating electricity. A flexible shaft supported by guy wires is provided at its upper end with a flexible rotor and an airfoil assembly. Rotation of the airfoils in response to wind creates centrifugal force and tension which causes the rotor to become rigid during use. The light flexible shaft easily follows the rotating sails, which permits the entire turbine to automatically track the wind as it changes direction. As the rotor spins, its rotational energy is transferred to the shaft, which rotates along its entire flexible length.

대표청구항 ▼

A flexible tethered wind turbine comprising: a flexible and resilient load-bearing drive shaft having upper and lower ends, said shaft being tapered toward the upper end along at least a portion of its length, and being straight in a non-rotational rest mode and actively bendable in response to changing wind conditions through a curve in a rotational operating mode; a flexible and non-resilient rotor having a hub and a rim, said hub being affixed to the upper end of said shaft and having at least one flexible sail affixed to said hub and rim, said rim being flaccid in the non-rotational rest mode and firm in the rotational operating mode; a first support means having a lower bearing in axial cooperation with said shaft, proximate to the lower end thereof, said lower bearing permitting free rotation and restrained vertical and horizontal movement of the shaft; and a second support means comprising an upper bearing disposed on the shaft between said lower bearing and said upper and, and guy wires affixed to said upper bearing via restraining means in a manner which tethers said shaft without interfering with the rotation and movement thereof.
