A reaction-type turbine provided with an output shaft coupled to a power generator, such as an electric generator, and having a plurality of variable-pitch flexible impeller blades, or sails, mounted between the periphery of the output shaft and a concentric tubular shroud rotatable in unison with the output shaft. The pitch of the flexible impeller blades or sails is varied by a centrifugally-actuated pitch controlling unit such that the output shaft has a constant angular velocity irrespective of variations in the velocity of the fluid flowing through the turbine. For actuation by wind, the turbine is mounted on a rotatable platform which is automatically oriented in the direction of the prevalent wind by a servo system controlled by a wind direction detecting device. The mass of air flowing through the turbine is automatically controlled as a function of the wind velocity by an appropriate throttling mechanism controlled by a wind velocity detector. For actuation by water flow, the turbine is mounted such as to be retractable and extendable relative to an appropriate support hull.

A reaction-type turbine rotatable by fluid flow longitudinally therethrough, said turbine comprising a rotatable output shaft, a rotatable tubular shroud disposed concentric to said output shaft, means rigidly interconnecting said output shaft and said tubular shroud for rotation in unison, and a plurality of flexible impeller blades disposed radially between said output shaft and the interior surface of said tubular shroud, said flexible impeller blades having a leading edge, a trailing edge and a pair of opposed lateral edges, one of said lateral edges being fixedly attached to said output shaft and a portion of the other of said lateral edges proximate said leading edge being fixedly attached to the interior surface of said tubular shroud, and means for controllably uniformly varying the pitch of said impeller blades by displacing the peripheral corner of the trailing edge of said blades such as to place said trailing edge at an angle to the leading edge of said blade.
