    • The wind turbine has a central axis that supports pairs of blades offset by 90°, each pair is integral with a single supporting shaft able to rotate relative to the central axis of the turbine owing to coupling by means of bearings. The pairs of blades are orientated automatically in order to present the maximum possible surface area of the blades to the wind when they move in the direction of the wind, at the same time minimizing the surface area of the blades when they move against the wind. The large surface exposed to the action of the wind is not opposed by a braking action due to the blades moving against the wind, which produces a very high torque on the central axis. The turbine operates with the wind blowing from any direction and is able to start moving even in the presence of very light winds.
    • 风力涡轮机具有支撑成对的叶片偏移90°的中心轴线,每对与由于通过轴承联接而能够相对于涡轮机的中心轴线旋转的单个支撑轴线成对。 成对的叶片自动定向,以便当它们沿风向移动时呈现叶片对风的最大可能表面面积,同时使叶片相对于风移动时的表面积最小化。 暴露于风的作用的大表面不会由于叶片相对于风而运动而产生制动作用,这在中心轴上产生非常高的扭矩。 涡轮机以风向任意方向运转,即使存在非常轻的风也能开始移动。
