摘要： A propeller type runner is described in which the leading edge of each blade "leans" forward from the root in the direction of rotation to reduce cavitation and increase efficiency. The "lean" provided to each blade of a five blade design is such that the leading edge of each blade obscures a large portion of the trailing edge of the preceding blade.

摘要： The application relates to unidirectional hydrokinetic turbines having an improved flow acceleration system that uses asymmetrical hydrofoil shapes on some or all of the key components of the turbine. These components that may be hydrofoil shaped include, e.g., the rotor blades (34), the center hub (36), the rotor blade shroud (38), the accelerator shroud (20), annular diffuser(s) (40), the wildlife and debris excluder (10, 18) and the tail rudder (60). The fabrication method designs various components to cooperate in optimizing the extraction of energy, while other components reduce or eliminate turbulence that could negatively affect other component(s).

摘要： The invention disclosed herein comprises a system focusing water current into a relatively smaller diameter lumen, imparting vortical movement to the current, and directing the water vortex through an even smaller diameter lumen en route to turbine blades having long curved blades rotatable along an axis parallel with the lumen. Rotation of the turbine blades turns gearing interfacing with the circumference of the turbine assembly, to rotate a drive shaft connected to a generator.

摘要： The present disclosure relates to a turbine for hydraulic power generation comprising two bladed wheels (11, 12, 31, 32) successively arranged in a turbine tube section (10, 21) as a fore wheel (11, 31) and an after wheel (12, 32) with respect to the water flow direction (23) along a common rotation axis (30) extending in the water flow direction (23), the wheels (11, 12, 31, 32) being configured to rotate in opposite directions driven by the water flow, and to a corresponding hydroelectric power plant. In order to improve the turbine characteristics for hydraulic power generation, in particular in view of low head power generation, the invention suggests that a first gear (46) and a second gear (47) are arranged along the rotation axis (30), each connected to a wheel (11, 12, 31, 32) and mutually connected via an engagement gearing (48) such that the fore wheel (11, 31) and the after wheel (12, 32) are coupled to each other with respect to their rotation speed, the engagement gearing (48) being connectable to a power generator.
