A wind turbine has an internal rotor carrying a plurality of turbine vanes in a circular path between an inlet opening and an exhaust opening. The inlet opening includes a stationary dividing vane that delivers one portion of the inlet airflow to a primary flowpath traversing the turbine vanes at two locations. The stationary dividing vane also delivers a second portion of the inlet airflow to a second flowpath which drives the turbine vanes as those vanes move in the part of the circular path from the exhaust opening toward the inlet opening. The turbine vanes may be mounted so as to have variable angular positions in different portions of the circular path. Turbine vane position can be controlled either magnetically or mechanically. Where vane position is varied magnetically, a plurality of permanent magnets with suitable controls adjust the turbine vane position. Where vane position is varied mechanically, a pair of cam arrangements may be employed.

[ What is claimed is:] [1.] A wind driven turbine device comprising:a housing having sides, a primary inlet opening, a secondary inlet opening within the primary inlet opening, an exhaust opening, and guidance means for orienting the primary inlet opening in general alignment with atmospheric wind;turbine means for generating rotary power from atmospheric wind, rotatably mounted in the housing for movement in response to atmospheric wind movements;baffle means for directing wind through the housing and the turbine means, the baffle means connecting the primary inlet opening, secondary inlet opening, and the outlet opening of the housing while defining an annular path for the turbine means, directing a first portion of wind from the primary inlet through a first portion of the annular path, directing wind from the secondary inlet through a second portion of the annular path and into confluence with a second portion of the wind from the primary inlet, and directing confluent second portion of wind from the primary inlet and wind from the secondary inlet outwardly through the turbine means to the outlet;mounting means attached to the housing for rotatably supporting the housing while permitting movement of the housing about an axis; andmeans for moving individual ones of the turbine blades between a first position and a second position during movement of the rotor within the housing.
