Abstract
A runner type wind turbine designed to utilize maximum of the available energy carried by low speed stream. This turbine has a turbine disc which deflects and discharges a wind stream in radial and parallel direction relative to the disc; a rotor construction permits the disc and its power shaft to be arranged and assembled in a vertical or a horizontal position. The turbine includes a disc, mounted on a shaft located in central guides affixed to an outer stationary turbine stand. The disc mounts a plurality air blade shaped in such a way that the incoming air impinges on the blades radially, circumferentially and outwardly relative to the turbine disc.
Claims18
A turbine blade, for use in a wind turbine, for receiving a flow of air from a windstream at an inlet of said blade and deflecting the air to an outlet of said blade, the blade comprising a pair of opposed planar sides joined by a arcuate portion to form a hollow conoidal shaped body having a longitudinal axis and tapering from said inlet to said outlet, and a cross-section decreasing longitudinally along said axis, from said inlet to said outlet, means for connecting the blade with said axis of the hollow conoidal shaped body at an angle to said flow of air to the blade.
The device of claim l, wherein said conoid-shaped body has a pair of spaced-apart lateral sides, each one of said pair having angularly disposed terminal side edges extending upwardly and outwardly towards said discharge outlet.
A method of recovering usable energy from a moving fluid stream having a principal fluid flow in a primary first direction comprising disposing a conoid-shaped body in said fluid flow, said conoid-shaped body having a hollow interior in which said hollow interior faces said fluid flow direction, intercepting a first component of fluid flow of said fluid stream in an inlet portion of said conoid body to deflect said first component and tangentially to the principal fluid flow direction of said fluid stream, angularly intercepting a second component of said fluid flow within said conoid-shaped body and deflecting said intercepted second component in tangentially of the fluid flow direction, combining the axial fluid flows of said first and second components, causing the combined axial flow to pass through an area of reduced cross-section, and deflecting the combined axial flow in a direction angularly disposed relative to the principal direction of the combined axial flow.
A blank for forming a turbine blade comprising a sheet of bendable non-flexible material, said sheet having a generally planar configuration with a pair of opposed major surfaces, said sheet forming a body having a first side forming an arcuately contoured inlet edge for said body, a pair of opposed lateral sides angularly disposed relative to said contoured first side and extending backwardly and outwardly therefrom, a second pair of sides angularly disposed relative to said first pair of sides and extending inwardly and rearwardly of said body, and a rearwardly projecting recess between said sides of said second pair of sides, said blank being bendable along an axial line extending between said first arcuate side and said last mentioned side to form a body of a generally conoid configuration.
