A reactive blade turbine system works vertically, horizontally, or at an angle and clockwise or counterclockwise according to blade angle and locking position and adjusts to variations in fluid flow such as changes in tidal currents to generate power more efficiently regardless of direction of fluid flow.

The present invention provides a turbine sub-runner that is positioned to be within the vortex zone of a turbine wicket gates (zone “S—R”, FIG. 1). The sub-runner includes at least two sub-runner blades, configured to monitor the relative flow of the vortex created by the wicket gates. A control mechanism is connected to the sub-runner shaft via gear and threaded interface, and is capable of transferring the relative (vs main-runner) rotational energy of the sub-runner into angular movement of the main runner blades. As the sub-runner interacts with the changing conditions of the main vortex within the zone “S—R”, it will act to automatically regulate, adjust, and control the angle of the main runner blades to optimize the performance of the turbine. The sub-runner uses the energy of the vortex existing in the zone “S—R” to perform the monitoring, regulation, adjustment and control of the main runner through regulating angular position of main runner blades.

A marine current turbine rotor comprises a hub and fixed and two or more pitchable blade sections configured to reduce bending moment loads on the pitch bearings and enable the use of non-standard, low-cost structural materials for the hub, blades, and pitch shaft. A submersible pitch drive mechanism or linkage in the hub rotates the pitch shaft to cause the pitchable blade section to move to a specified pitch position. The hub cavity is configured to be “wet” without the expense and maintenance requirement of seals to prevent water intrusion, utilizing water-lubricated pitch bearings.

A turbomachine module with a longitudinal axis, the module comprising: a rotary casing rotatable around the longitudinal axis and arranged to carry a propeller provided with a plurality of blades; a system for changing the pitch of the blades of the propeller comprising: a control, and a mechanism for varying the pitch of the blades of the propeller connecting these blades to the control, wherein the control comprises a rotary actuator comprising a control body and a reference body which is integral with the rotary casing, and wherein the mechanism for varying the pitch comprises a synchronization ring which is driven in rotation around the longitudinal axis by the control body and which is guided in rotation on the rotary casing, the synchronization ring being connected to the blades.

A hydrodynamic power generation assembly and method of use therefor for generating electrical power from the combination of kinetic energy, hydrostatic energy, and turbulent energy of water. The power generation assembly comprises a water accelerator assembly comprising a support structure which is at least partially buoyant and a baffle panel member (or an array of baffle panel members) having an opening, inter-panel spacing, or flow passageway around the baffle panel(s). A hydropower converter is supported from, by, or on the support structure and is operatively coupled to a generator. The hydropower converter is positioned behind baffle assembly. Water flowing through or around the baffle assembly has an increased velocity relative the ambient current and therefore is capable of generating more power relative to the ambient water where power generation assembly is deployed. Particular types of hydropower converters suitable for use with the invention are turbines and water wheels.

The present invention provides a turbine sub-runner that is positioned to be within the vortex zone of a turbine main runner. The sub-runner includes at least two sub-runner blades, configured to monitor the relative flow of the vortex created by the main runner. A sub-runner hub will be positioned downstream of the main runner blades. A sub-runner shaft, having a threaded section, will also be a part of the sub-runner, and will be connected to the sub-runner hub housing adjustable sub-runner blades and the mechanism enabling to regulate angular position of sub-runner blades. A main runner blades control mechanism will be connected to the sub-runner shaft via threaded interface, and is capable of transferring the rotational energy of the sub-runner into angular movement of the main runner blades. As the sub-runner interacts with the changing conditions of the main runner vortex, it will act to automatically regulate, adjust, and control the angle of the main runner blades to optimize the performance of the turbine. The sub-runner uses the energy of the sub-runner blades to perform the monitoring, regulation, adjustment and control of the main runner through regulating angular position of main runner blades.

A hydrokinetic turbine system for harvesting energy from riverine and tidal sources, including a first floating dock, a marine hydrokinetic turbine mounted on the first floating dock, and a second floating dock. The system further includes a winch assembly mounted on the second floating dock and operationally connected to the first floating dock and a linkage assembly operationally connected to the first floating dock and to the second floating dock. The linkage assembly may be actuated to pull the first floating dock into contact with the second floating dock. The linkage assembly may be actuated to distance the first floating dock from the second floating dock, and the winch assembly may be energized to orient the first floating dock into a position wherein the marine hydrokinetic turbine is above the first floating dock and wherein the winch assembly may be energized to orient the first floating dock into a position wherein the marine hydrokinetic turbine is below the first floating dock.

A kinetic fluid energy to mechanical energy conversion system includes hubs that are rotatable with respect to a hub carrier and support one or more independently controlled articulating energy conversion plates (“ECP”) and a track orientation control mechanism (“TOCM”) for alternating the independent control of each ECP in response to operating conditions. Each ECP has opposed surfaces and leading and trailing edges and may have one or more lips projecting from one of the opposed surfaces, wherein the one or more lips comprise at least an inboard end lip extending transversely from an inboard end of the plate. Articulation of each ECP is controlled by a follower within a track that is rotatable with respect to the hub carrier, and service lines pass through a chase or bore passing through the hub carrier to bring power and/or control signals to the TOCM for effecting controlled, powered rotation of the track.
