The directing system includes a base structure, a plurality of directing segments attached to the base structure, downstream of the base structure, and a directing segment adjustment system for adjustably positioning the directing segments between a retracted configuration and a deployed configuration. The directing segments, in the deployed configuration, extend beyond the base structure in a direction transversal to the inlet flow direction and deflect the fluid towards an outer circumference of the plurality of turbine blades corresponding to a higher torque area of the blades. A directing system for directing fluid entering a cross-flow turbine is also disclosed. In the cross-flow turbine, the fluid is directed towards a centerline of the rotor of the turbine, which is a high torque area of the turbine blades.

    摘要： A wind driven electrical power generating apparatus includes a rotor rotating by receiving wind force, a gear assembly having an input shaft connected to the rotor, a generator connected to an output shaft of the gear assembly, a sensor for detecting generating capacity of the generator and a controller for varying gear ratio of the gear assembly based on a signal from the sensor. In this construction, the controller controls so that the generator keeps rotating at around the lowest rotational speed within a range of rotational speed, the range being determined so as to include a maximum power operation region of the generator. Alternatively, the controller controls so that rotational speed of the output shaft of the gear assembly is adjusted to at around the lowest rotational speed within a range of rotational speed, the range being determined so as to include a rated power region as an upper operational limit.

    摘要： The disclosed wind turbine has a circular turbine wheel with a plurality of soft, furlable and unfurlable airfoils depending between a rim and hub. Each airfoil has associated with it a stepping motor for selectively furling and unfurling the airfoils. The turbine wheel is supported on a carriage which is in turn supported in a cantilevered manner from a central anchor which allows for revolving of the carriage, and therefore the turbine wheel, about the anchor. Control is provided for rotating the turbine wheel into a position upwind and normal to the wind direction. An upstanding pylon mounted on the anchor maintains the turbine wheel in an upright position. The pylon allows for revolving and rotating of the turbine wheel. It also provides for pivoting of the turbine wheel about a generally horizontal axis parallel to and spaced from the plane of the turbine wheel. A plurality of generators are driven by power take-off wheels mounted on the carriage which directly support the turbine wheel rim. Turbine wheel rotational speed control is maintained by varying the number of generators driven by the power take-off wheels and by furling and unfurling the airfoils.
