A lift-driven wind turbine has a turbine rotor with blades mounted to the turbine shaft by two struts hinged to the shaft and each blade to form a four-bar linkage. The blades' airfoil cross section generates lift that rotates the blades around the axis in the presence of a prevailing wind. The airfoil chord forms a geometric angle of attack &#x3b1;relative to the tangent of the blade path and the struts orient the blades with an outward tilt angle &#x3b3;. The turbine is designed with values of &#x3b1;and &#x3b3; that cause the lift generated by each blade to have an upward component that supports the blade against the force of gravity and a mean radially inward component that substantially balances centrifugal forces on the blade. Wind turbines designed according to the principles disclosed herein facilitate the construction of free-floating utility scale wind turbines for deep water installations.
