  • Adjustable fins on a turbine
    Patent number: 11971004
    Abstract: A downhole turbine includes a plurality of fins. The plurality of fins have an exit angle that exerts a tangential force on the fin, which imparts a torque on a hub. The fins have an adjustable exit angle that changes in response to changes in the properties of a drilling fluid. The changing exit angle changes the tangential force, which changes the torque on the hub.
