摘要： A sky turbine, having impeller blades with a plurality of panels that can telescope inward and outward. The pitch of the panels can be adjusted, and the pitch of each panel on a blade, passing from the innermost panel to the outermost panel, differs from the pitch of the previous panel by a certain adjustable amount. The sky turbine is preferably mounted above a city at a sufficiently high elevation that air current will be generally faster than just above the ground. In the preferred embodiments, a wing with two pods is pivotally mounted on a tower. Each pod has front and rear shafts, from which four blades extend. Servomotors cause the wing to turn so that its center of symmetry is parallel to the direction the sky is moving, cause the pitch of the panels of the blades to change, and cause the panels of the blades to telescope.

摘要： A wind turbine blade made of a fixed blade section with an integral mounting flange for attachment to a wind turbine hub. A moveable blade section is attached to the fixed blade section and is free to move in a longitudinal direction relative to the fixed blade section. A positioning device controllably positions the moveable blade section to vary the overall length of the blade. This allows the wind turbine's rotor diameter to be adjusted. The rotor diameter can be increased in order to provide high power output in low wind conditions and it can be decreased in order to minimize loads in high wind conditions.

摘要： A system and method for changing wind turbine rotor diameters to meet changing wind speeds and control system loads is disclosed. The rotor blades on the wind turbine are able to adjust length by extensions nested within or containing the base blade. The blades can have more than one extension in a variety of configurations. A cable winching system, a hydraulic system, a pneumatic system, inflatable or elastic extensions, and a spring-loaded jack knife deployment are some of the methods of adjustment. The extension is also protected from lightning by a grounding system.

摘要： Opposing windmill airfoil blades extend from a central hub and are connected thereto by a pair of cables secured to the inner ends of the blades and which each freely engages through the opposite ends of a cross member secured to the hub. These cables then extend to a reel on the hub thus forming a triangular configuration to support each airfoil blade. The reel is driven by a small reversible electric motor which extends and retracts the cables and hence the blades depending upon the tension in the cables which is sensed by a sensor which in turn actuates the electric motor. As the wind speed increases in velocity, the cables lengthen and vice-versa. Guide vanes or control tail wings extend from adjacent the inner ends of each of the airfoil blades and are fixed in manufacture thus automatically presenting the desired angle of attack of the airfoil blades to the wind. The rigidity of the cables, due to centrifugal force, allows the rotation of the assembly to rotate the shaft extending from the hub which may drive a generator. Conventional yaw control means are provided to maintain the blades in the desired direction relative to the wind direction.
摘要翻译： 相反的风车翼型叶片从中心轮毂延伸并且通过固定到叶片的内端的一对缆线连接到其上，并且它们通过固定到轮毂的横梁的相对端自由地接合。 这些电缆然后延伸到轮毂上的卷轴上，从而形成三角形构造以支撑每个翼型叶片。 卷轴由小的可逆电动机驱动，该小型可逆电动机根据由传感器感测到的电缆中的张力来延伸和缩回电缆，因此叶片依赖于电动机的张力，传感器又致动电动机。 随着风速的增加，电缆延长，反之亦然。 引导叶片或控制尾翼从每个翼型叶片的内端部相邻延伸，并且在制造中固定，从而自动地将翼型叶片的迎角迎接到风中。 由于离心力，电缆的刚度允许组件的旋转以使从轴心延伸的轴旋转，这可以驱动发电机。 提供常规的偏航控制装置以将叶片相对于风向保持在期望的方向。

摘要： The lengths and/or chords and/or pitches of wind turbine or propeller blades are individually established, so that a first blade can have a length/chord/pitch that is different at a given time to the length/chord/pitch of a second blade to optimize performance and/or to equalize stresses on the system.
