Abstract
A horizontal axis wind-turbine includes a stationary support structure, a two-bladed rotor supported by the stationary support structure, and a hollow shaft rotationally attached to the stationary support structure through a bearing. Teeter hinges are spaced apart from each other and connect the hollow shaft to a rotor-hub to allow a teetering action of the rotor-hub with respect to the hollow shaft. The hollow shaft structurally supports the two-bladed rotor with respect to the stationary support structure, with a maximum outer diameter of the hollow shaft being greater than an outer diameter of the bearing.
