    摘要： There is provided an adjustable vane turbine and turbine generator using the same, in which hydrodynamic properties are employed to adjust adjustable vanes automatically in response to flow condition such as the flow rate of the working fluid, thereby simplifying the system using the adjustable vanes and reducing cost. In the adjustable vane turbine, a turbine wheel is installed in a turbine housing and rotatably supported by a shaft, and a plurality of adjustable vanes are movably installed between the turbine housing and the turbine wheel, wherein each of the adjustable vanes includes an adjustable vane member having one end portion rotatably fixed to the turbine housing, a vane control element attached on one side of the adjustable vane member at a set angle, and a guide element attached on the other side of the adjustable vane member, the plurality of adjustable vanes being connected using links between neighboring vanes.

    摘要： A system is provided to adjust the operating angle of attack of a variable pitch impeller blade in response to different conditions. The impeller blade is pivotally mounted around a pivot axis and a small control surface attached to the blade provides a turning moment around the pivot axis to oppose a similar moment provided by the lift component of the blade. The operating angle of attack of the blade is determined by the angle at which the moment from the control surface tapers off as it approaches stall range, thus equalizing the moment from the impeller blade.
