摘要： A water power plant for the generation of electric current from a flowing medium by means of a turbine, which includes a housing around which the flow passes on an outer side, a stator of an electric generator which operates in a low-speed mode, and a rotor of the generator, which is rotatably mounted relative to the stator. The rotor includes a rotor ring with an annular surface and, starting from the rotor ring, an arrangement of inwardly extending turbine blades, thereby defining a free-standing axis of rotation. The housing defines an inlet portion with a first front-side cutting edge which delimits a circular inlet opening, from which extends an inlet-side guide surface to the rotor, and an outlet portion with an outlet opening, between which a flow path passing the rotor ring can be formed. It is provided that the inlet opening has a free inlet cross-section which is maximally as large as a cross-sectional area delimited by the rotor ring.

摘要： Described herein is essentially a high-efficiency, hybrid fluid-aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid-flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle-effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle-effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency, than is possible in conventional blade-type wind turbines.

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.

The OWC turbine includes a shaft (101) rotatable about a central axis (103), and first and second ports (112, 114) disposed around the central axis. A flow passage (104) extends radially-inward from the ports and extends axially therebetween. Rotor blades (120) are coupled to the shaft, intersect the flow passage, and are offset from the central axis by a first distance. First guide vanes (116) intersect the flow passage and are disposed proximal the first port. The first guide vanes (116) include first and second stators (116a, b), the first stators (116a) being positioned between the first port (112) and the second stators (116b). Second guide vanes (118) intersect the flow passage and are disposed proximal the second port. The first and second guide vanes are offset from the central axis by a second distance that is greater than the first distance.

摘要： A power generator assembly for using kinetic energy from a flowing fluid to generate power. The power generator assembly includes a blade assembly and a generator. The blade assembly has a head end for facing oncoming flowing fluid, a tail end spaced from the head end for facing in the direction of flow of the fluid, and a rotational axis extending between the head end and the tail end. The blade assembly includes a blade arrangement which is arranged in generally helical fashion about the rotational axis, and at least one mounting formation connected to the blade arrangement. Each mounting formation is adapted to permit mounting of the blade assembly for rotation about its rotational axis, so that in use fluid flowing past the power generator assembly interacts with the blade arrangement to rotate the blade assembly about its rotational axis. The generator is drivingly connected to the blade assembly for generating power in response to rotation of the blade assembly.

摘要： A device having a pair of blades spinnable about a spin axis. The pair of blades includes a first blade and a second blade, with the first blade canted about a first-blade canting axis at a first-blade canting angle and the second blade canted about a second-blade canting axis at a second-blade canting angle. The first-blade canting axis is oriented at a first-blade canting axis angle relative to a first-blade radial and the second-blade canting axis is oriented at a second-blade canting axis angle relative to a second-blade radial, each canting axis angle being other than 90 degrees. The first-blade radial is oriented perpendicular to a first chord plane that passes through the first blade and contains a first-blade chord, and the second-blade radial is oriented perpendicular to a second chord plane that passes through the second blade and contains a second-blade chord. The first-blade chord is oriented at a first-blade chord pitch angle determined at least in part by the first-blade canting axis angle and the first-blade canting angle. The second-blade chord is oriented at a second-blade chord pitch angle determined at least in part by the second-blade canting axis angle and the second-blade canting angle.

摘要： An unevenly loaded turbine blade is disclosed including a first region configured for extracting power from a fluid flow and a second region configured for adding power to the fluid flow. The power extracted from the fluid flow is typically greater than the power added to the fluid flow resulting in a net power extracted for the blades. The addition of power to the fluid flow advantageously results in localized injections of high velocity fluid flow which provide distributed mixing of wake and tip vortices along the length of the blade.
