    摘要: The invention resides in providing a windmill for highly efficient wind power generation by enabling to efficiently rotate the windmill even in starting or at a low wind speed region by improving a blade of a vertical shaft type windmill of a lift type. In a windmill for wind power generation in which a plurality of blades are provided in parallel with a rotating shaft in a face orthogonal to the vertical rotating shaft at constant angles centering on the rotating shaft, the blade is of a blade type having a high lift coefficient at low Raynolds number and a notch portion is formed at a rear edge portion of a lower face of the blade.

    摘要: The present invention concerns a rotor blade for a wind power installation and a wind power installation comprising at least one rotor blade according to the invention. The smaller the surface area on which the wind acts, that is to say in particular the rotor blade area, the correspondingly lower is the load level for which the installation has to be designed and the correspondingly more easily can the rotor blade be transported. On the other hand the size of the wind power installation entails minimum dimensions which are unavoidable for operation and below which the installation dimensions may not fall. In order to provide a rotor blade which on the one hand has the aerodynamically required surface area but which on the other hand is so designed that the surface area of the rotor blade and therewith the depth thereof can be reduced in predetermined situations a part of the surface of the rotor blade is deformable or movable.

    摘要: The invention relates to a method and a device for regulating the airflow around a blade of a windmill. The device comprise a spoiler, which is provided with a cavity. The spoiler is mounted to a surface of the blade in connection with an another flow regulating unit, and the spoiler can change the airflow around the blade by assuming 12 different forms. When the spoiler is in a deactivated form no particular changes of the airflow takes place, as the spoiler runs continually and follows the contour of the blade. When the spoiler is in an activated form the airflow, however, is changed in that the spoiler no longer follows the contours of the blade and creates a discontinuity or at least changes the profile of the blade in such way that the airflow conditions are changed. In particular the airflow conditions can be changed so the effect of the second flow regulating unit completely or partly is eliminated. The change of the form takes place by supplying a fluid, such as compressed air or hydraulic oil, to the cavity in the spoiler. The change of the airflow is an advantage in that is thus is possible to regulate the speed of rotation of the rotor, which the blade is mounted on.

    摘要: The present invention relates to a windmill power generation system which includes at least two variable camber blades fastened to a rotatable hub, which blades are driven by a fluid such as wind. Each of the variable camber blades has embedded shape memory alloy members. The system also includes a source of electrical power connected to the shape memory alloy members for varying the shape of the blades in response to changes in the speed of the fluid driving the blades. The power generating system further includes a power regulator connected to the electrical power source for regulating the electrical power being supplied to the shape memory alloy members and a controller for transmitting a power command signal to the power regulator. The controller preferably comprises a preprogrammed computer having an algorithm for generating the optimum blade shape for a particular wind speed or condition.

    摘要: An apparatus may include a cage that rotates around a cage axis and a turbine located at an end of the cage and rotating around a turbine axis. A turbine blade may have an adaptable shape. A frame of the turbine blade may have a first frame portion that pivots relative to the second frame portion. The curvature of the turbine blade may be controlled by shortening a connection while concurrently lengthening another connection. Controllers may control the rotation of the cage(s) and/or turbine(s) based on a speed, a direction, a velocity, an acceleration of wind, and/or a load carried by the apparatus. The apparatus may be a Savonius machine. Rotation of the cage(s) and/or turbine(s) may induce a Magnus effect. A seat and user controls near the seat may be included. The user controls may control the rotation of the cage(s) and/or turbine(s).
