摘要： A wind turbine for producing electricity using wind. In a power generating section, a driving shaft, columns, and a guide shaft are installed between a base frame fastened to a support plate and a cover frame positioned above the base frame. Guide rails are fastened to the columns to define closed loops which surround the driving shaft, guide shaft and columns. Sail structures each of which can be adjusted in its wind pressure acting area by means of a geared motor and a coil spring are connected to sprocket chains provided in the guide rails such that the sail structures can be moved along the guide rails by wind force to rotate sprocket chains and sprockets of the driving shaft which are meshed with the sprocket chains. Two power generating sections are installed to transmit power generated by the driving shaft to an auxiliary sprocket through power transmitting chains.

摘要： A Vertical Axis Wind Turbine comprising: A hub housing an alternator or generator, gearbox, arbor, tachometer and programmable logic controller. At the upper outer radius of the hub is a track supporting the landing gear for the wind rotor. Above the hub a large elongated wind rotor is attached to the arbor with landing gear that ride on the track. The rotor is the support structure providing anchoring for masts, sails and boom control systems. Attached to the top/center of the rotor is a tower with cables supporting the outer perimeter portions of the rotor arms. At the top of the tower is a weathervane and position controller. Fabric sails are attached to the mast assemblies and controlled by resolvers. When the wind causes rotation the programmable logic controller adjusts the sails to best catch the wind regardless of wind direction or their position while the rotor is rotating.

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 invention details a method of determining and controlling the attack angle of fixed-speed wind turbine blade aiming at finding out an appropriate angle of attack for optimal extraction of wind energy at low to medium wind speed, which comprises three steps: step 1—defining basic parameters of the turbine including the blade length and width, fixed rotational speed, rated wind speed, start-up speed and the lowest speed at which the turbine is forced to stop, and the relationship with the wasted power; step 2—defining wind speed based on which a set of attack angles can be calculated to form an overall optimal attack angle of the wind turbine blade; step 3—calculate necessary physical parameters to come up with the most effective method of controlling the turbine blade; this invention is applicable to the manufacture of fixed speed wind turbine that can be directly connected to the grid, making wind power costs as low as those of other conventional energy sources.
