Description
- 1. Field of the invention
- The present invention relates to turbines for power generation.
- 2. Description of Related Art
- The use of fluids to generate power or rotate turbines to generate thrust is well known. However, the vast majority use propellers, fins, and the like to transform energy from fluid flow to power generation. For example, U.S. Pat. No. 2,996,266 to Rebasti uses fan blades to blow air down through his device; U.S. Pat. No. 2,997,254 to Mulgrave et al. uses a fluid impeller; U.S. Pat. No. 4,021,135 to Pedersen et al. uses two curved cowlings to guide air into the turbine blades, and to create a vortex downwind of the turbine blades to make the blade spin faster; and U.S. Pat. No. 4,066,381 to Earnest uses a stator to redirect the flow and uses fan blades to impel fluid through holes.
- Other developments include U.S. Pat. No. 4,140,433 to Eckel uses a plurality of fixed blades to guide air into the turbine blades, and one curved cowling to create a vortex downwind of the turbine blades to make the blade spin faster; and U.S. Pat. No. 5,170,963 to Beck which discloses a fluid flow pattern which exits radially from the fan axis of rotation.
- However, there remains a need for more efficient, economical, and safer turbines. This invention satisfies these needs among others.
- The present invention is a fluid-powered turbine with many unique features which increases rotational velocity and torque over conventional turbines. In particular, the turbine has two impulse-type turbine portions which, when used in combination, synergistically create increased power from a fluid input by twice extracting energy from the fluid, thereby increasing the turbine's efficiency. More particularly, the first impulse-type turbine portion rotates as ambient fluid is passed through a plurality of chutes. After passing through the chutes, the fluid is then reused by directing it to the periphery of the device where it contacts a second impingement-type turbine portion, thereby extracting additional energy from the fluid.
- This turbine also uses vastly more surface area than previous developments, which increases the surface area available for impingement, thus facilitating rotation of the rotor assembly. Additionally, it uses the energy of the flowing fluid in multiple stages to increase power. Because of this, the turbine will rotate much more rapidly compared to conventional turbines, based upon comparable fluid input, thus generating more torque. Additionally, when used as a windmill or other exposed turbine, the hazard of killing birds or other wildlife is substantially reduced due low profile vanes.
- Accordingly, provided is a turbine comprising a rotatable shaft having an axis of rotation; and a rotor assembly comprising (a) a rotatable disk having a direction of rotation, a center to which said rotatable shaft is joined, a front surface, a rear surface, and a perimeter, (b) a first impingement-type turbine portion comprising a plurality of chutes disposed between said front and rear surfaces, wherein each chute comprises an impingement surface, a chute inlet, a chute outlet, and a chute channel fluidly connecting said chute inlet and chute outlet, wherein said impingement surface is sloped from the front surface to the rear surface and orthogonally with respect to a radial direction of said disk, and (c) a second impingement-type turbine proportion comprising an upstream rotor and a downstream rotor, wherein said upstream rotor comprises a plurality of ducts disposed between said front and rear surfaces, wherein each duct has a duct inlet fluidly connected to one of said chute outlets, a duct outlet disposed at said perimeter, and a channel fluidly connecting one or more of said duct inlets to one of said duct outlets, and wherein said downstream rotor portion comprises an annular rim having a periphery, and a plurality of vanes joined to said rim and disposed along said periphery, wherein said vanes have a primary fluid contact surface and wherein said primary fluid contact surface is in a plane parallel to said axis of rotation and is angled from about 45 to less than 90 degrees from a radial direction from said disk..

In certain embodiment, said impingement surfaces comprise a majority of said front surface. - During operation, fluid traveling toward the
rotor assembly 30 contacts theimpingement surfaces chute inlet 51, through thechute channel 53, and to thechute outlet 52. This fluid flow causes therotor assembly 30 to rotate in the direction ofrotation 42 which, in turn, causes the rotor shaft to rotate. The rotating shaft can then be used to generate power. - Upon exiting the
chute outlet 52, the fluid enters a second impingement-type turbine portion 60 of the rotor assembly. (FIG. 2 ) The second impingement-type turbine portion of the rotor assembly comprises aupstream rotor 70 and downstream rotor 80 (FIG. 3 ).

In certain preferred embodiments, the upstream rotor is a part of the disk. - The downstream rotor comprises an annular rim having a plurality of
deflection vanes 26 attached to itsperiphery 82. In certain embodiments, the rim is attached to the disk. In certain other embodiments, the rim is a part of the disk. In still other embodiments, the rim and the disk are independently rotatable about the shaft.

duct inlet 62 through the channel in a radial orsemi-radial direction 68. In certain embodiments, the channel is constructed to increase the velocity of fluid flowing through the channel, preferably without substantially restricting the fluid flow through the channel. In certain embodiments, the chutes may have one or more devices, such as auxiliary openings, to facilitate high velocity fluid flow through the channel. - As the fluid exits the duct outlet it impinges the downstream rotor, causing the downstream rotor to rotate. For embodiments in which the downstream rotor and the upstream rotor rotate independently, the downstream rotor preferably rotates at a higher velocity compared to the upstream rotor.
- The turbine is preferably constructed of a plastic, metal, fiberglass or a composite material disk such as carbon fiber.
