Definitions
- This invention pertains to wind mill blades, blades for turning by a water flow and blades for turning in water, that are for mounting to an axle for turning in a frame that is fitted to a tower to turn in the wind and produce a power output for doing work, or for turning in water.
- the present invention is in a new and substantially more efficient wind powered blade structure than any presently available wind mill blade or blade arrangements. Examples of a variety of both old and new blade configurations are shown in U.S. Patents to Logsoon, No. Des.141,589; to Amico, No. 2,023,659; to Preston, No. 2,102,913; to Bunzer, No.4,109, 828; to Krolick, et al., No. 4,708,592; to Worfham, No. 4,779,006; to Arreola, Jr., No. 4,926,061; to Vainrub, No. 5,437.541; to Hosoda, No. 6,249,059; and to Zeng, No.
- the wind sail receptor design of the invention employs a pair of quad blades where each quad blade is formed from a continuous section of material, providing a stronger finished construction than is possible where individual blades are axially fitted together. In which fitting together, at equal distances around a front disk and rear hub, sail portions of the individual blades are equidistant from one another and overlap.
- the blade arrangement provides a greatly improved force of blade turning from even a light or variable wind in that the blades, when attached between the front disk and rear hub, are stiff and will efficiently derive energy from turning that is transferred into an axle connect between the blades front disk and rear hub, with that turning converted to useful energy, such as electrical energy, from a turning of a connected generated and with that produced energy to be stored in a battery or batteries, or can be directed into an electrical grid.
- wind mill blade configurations have lack efficiency, particularly the blades as are turned in a wind farm operation, and operate at only an efficiency of approximately twenty (20), thereby utilizing only a small percentage of the energy of a wind passing through the blades, and, accordingly, have had to be large to produce a worthwhile energy output.
- Present day examples of such wind farm type blades are long, heavy blades, usually three blades, that are both expensive to construct and maintain, particularly as to bearing wear.
- the wind sail receptor of the invention unlike such wind farm blades, or blades like those shown in the above cited prior art, provide a substantially greater efficiency, of approximately ninety (90) per cent in winds of from eight (8) to ten (10) miles per hour and greater, and utilizes a blade arrangement whose diameter is measured in inches rather than in feet.
- Such blade arrangement is far less expensive to construct and maintain, is a significantly more efficient than earlier blade configurations and is therefore a very significant improvement in wind power generation systems.
- Another object of the present invention is to provide, as a preferred blade arrangement, two sets of four equally spaced blades, that are connected axially, forming a single blade arrangement of a wind-powered device for converting wind energy into usable power.
- Another object of the present invention to provide a wind sail receptor were the individual blades are each curved from a leading to trailing edge to perform a function like that of a sail, like that of a head sail or jib of a sailing ship, and which blades are equally spaced from one another around a forward disk to where a flow of air passing across each blade leading edge acts around the curve of the blade to efficiently convert wind energy into blade rotation and turn an axle or shaft extending from the trailing face of a rear hub, turning a power generation device.
- Another object of the present invention is to provide a wind sail receptor where a trailing edge of each blade has an half round section proximate to a blade hub, that translates into a flat outer section that extends to the blade end, and is to provide a flow path for a wind traveling around the blade curved surface to discourage generation of turbulence in the flow at the blade trailing edge.
- Still another object of the present invention is to provide a novel design of wind sail receptor blades that, by their construction from a light gauge material, will respond to an increase in wing speed by becoming more rigid making each blade suitable for turning in even a high wind and water.
- Still another object of the present invention is to provide a wind sail receptor blade assembly having a minimum of one set of three to five blades, and preferably with two sets of blades forming a blade assembly of from six to ten blades, with the blade assemblies for axial assembly between an aligned forward disk and rear hub and with the individual blade bent around a selected arc and are attached, at equal spaced intervals to the forward disk, forming the three to ten equally spaced blades that overlap one another, providing uniform spacing between the blade leading edges, whereby an
- Still another object of the present invention is to provide a wind sail receptor where each set of blades is formed from a flat section of light gauge material where the individual blades are formed by a removal or like spaced curved sections that extend from the center area of the flat section, out to the section edge, squaring off the blade outer end edges and connecting an outer edge end of each blade to a forward disk.
- Still another object of the present invention is to provide a wind sail receptor that is simple and economical to produce where the single set or the two sets of blades are easily manufacture by stamping methods, and with the sets secured as a stack at their center rear hubs and with the individual blades formed by a connecting each blade outer edge end to a forward disk to form the wind sail receptor where the individual blades are equally spaced and including a shaft or axle fitted between the forward disk and rear hub to turn or be turned by a power producing device, producing a power output from the blade turning.
- the present invention is in a unique wind sail receptor configuration for inclusion in a wind power or water operated system where blade turning converts wind or water flow energy into usable power, or where blade turning provides thrust through water.
- Two wind sail receptor segments of three to five blades each can be used, with a four-blade assembly being preferred and are herein referred to as a quad blade assembly, for forming the wind sail receptor assembly.
- the two segments of three to five blades each are fitted one over the other and connected at rear hub sections, with ends of each of the blades then bent through a selected arc as determined by the relationship of the axial spacing distance between the rear hub and forward disk and the blade length between which hub and its connection point to the forward disk, with the blade ends connected, at spaced intervals, around the forward disk.
- a shaft or axle is secured between the rear hub sections and forward disk, and that shaft is journaled between bearings in a frame or housing to allow the shaft or axle to be turned by blade turning responsive to an air of water flow through the blades, or the axle itself can be turned to turn the blades in water to generate thrust.
- Each blade segment is formed from a flat section of a stiff material, such as from light gauge steel, plastic, fiberglass or an elastomeric material, such as urethane.
- a stiff material such as from light gauge steel, plastic, fiberglass or an elastomeric material, such as urethane.
- a hole is formed in a dog leg bend of each blade of each of two blade segments, and each blade is bent through an arc that is determined from the ratio of the length of the axle between the rear hub and forward disk to the length of the blade between its hub and the blade's mounting to the forward disk at the hole in the blade dog leg bend.
- Which ratio, to form the b lade of the invention, requires that the axle length be approximately point seventy-five (.75) to point eighty-five (.85) of the blade length.
- the pair of wind sail receptor sections are aligned over one another, and, with the rear hubs of each section aligned, each blade is bent through the arc determined by a ratio of the distance between the rear hub and front disk, with that hub to disk spacing ratio being from point seventy-five (.75) to point eighty-five (.85) of the blade length, connecting the blade dog leg bent to the forward disk, at one of spaced radial holes that are each equidistant from the center of which forward disk, forming the wind sail receptor.

- the curved blade surface receives an air or water flow that passes between the adjacent blades that is essentially without turbulence and acts upon that curved area that functions like a head or jib sail, efficiently converting wind or water flow energy into blade turning.
- the invention can incorporate the single blade section of three to five equal spaced blades that are fitted to an axle and, which blade assembly will still function like, though not as efficiently, as the stack of blade sections that form the six to ten blade assembly, within the scope of this disclosure.
- the invention can be mounted in a frame where the wind sail receptor is mounted to an axle journaled therein to turn freely to receive an air flow directed therethrough. Further, the invention mounted onto an axle can be turned by a power source in water to produce an output thrust.
- a frame is appropriate to mount the axle between bearing, and where the wind sail receptor is for use as a wind mill, such frame will be preferably mounted to a pivot that, in turn, will be fitted to pivot on, a pole, tower, or the like.

- an electrical generator 45 is shown herein as a device that the wind sail receptor 10 of the invention can be connected to so as to produce a power output, it should be understood that other devices that are turned to produce an energy output could be used within the scope of this disclosure, and that the wind sail receptor is suitable for turning in a liquid flow, such as water, and for turning in a liquid, such as water, to generate thrust.
- wind sail receptor 10 preferably includes the pair of wind sail receptor sections 11 that are axially connected together
- a single wind sail receptor section 11 can be utilized to produce wind power, within the scope of this disclosure.
- Such single section 11 would not, however, be as efficient in operation as is the pair of sections 11 arranged as the wind sail receptor 10.
