Publication number: 20120070275Abstract: Example embodiments described herein relate an integral and/or multi-piece airfoil and a shrouded fluid turbine having the same. The airfoil can have a generally circumferential body extending circumferentially about a central axis, and can be referred to herein as a “ringed airfoil.” The airfoil can have a front portion defining a leading edge of the airfoil and a rear portion defining a trailing edge of the air foil. A cross-sectional thickness of the front portion can be non-uniform and vary along a mean camber line of the airfoil from the leading edge to a transition area. A cross-sectional thickness of the rear portion can be uniform and constant along the mean camber line of the airfoil from the transition area to the trailing edge of the airfoil.Type: ApplicationFiled: September 16, 2011Publication date: March 22, 2012Applicant: FLODESIGN WIND TURBINE CORPORATIONInventors: Walter M.

Patent number: 8021100Abstract: A Mixer/Ejector Wind Turbine (“MEWT”) system is disclosed which routinely exceeds the efficiencies of prior wind turbines. In the preferred embodiment, Applicants' MEWT incorporates advanced flow mixing technology, single and multi-stage ejector technology, aircraft and propulsion aerodynamics and noise abatement technologies in a unique manner to fluid-dynamically improve the operational effectiveness and efficiency of wind turbines, so that its operating efficiency routinely exceeds the Betz limit. Applicants' preferred MEWT embodiment comprises: an aerodynamically contoured turbine shroud with an inlet; a ring of stator vanes; a ring of rotating blades (i.e., an impeller) in line with the stator vanes; and a mixer/ejector pump to increase the flow volume through the turbine while rapidly mixing the low energy turbine exit flow with high energy bypass wind flow.Type: GrantFiled: March 24, 2008Date of Patent: September 20, 2011Assignee: Flodesign Wind Turbine CorporationInventors: Walter M. Presz, Jr., Michael J. Werle

Publication number: 20110058937Abstract: A shrouded wind turbine comprises a shroud disposed about an impeller. The impeller surrounds a nacelle body which is shaped to enhance smooth flow of wind through the impeller. Some embodiments include an inlet and an outlet in the nacelle body, allowing airflow through an interior cavity. Other nacelle bodies may be tapered, flared, include mixing lobes around a trailing edge, or may have other shapes that enhance fluid flow. Some nacelle bodies include an annular groove that promotes flow attachment. Maintaining airflow attachment to the nacelle body within the turbine increases the energy generation capacity of the wind turbine.Type: ApplicationFiled: June 4, 2010Publication date: March 10, 2011Applicant: FLODESIGN WIND TURBINE CORPORATIONInventors: Walter M. Presz, JR., Michael J. Werle, Thomas J. Kennedy, III, William Scott Keeley

Publication number: 20110027067Abstract: A wind turbine has an impeller surrounded by a shroud. The shroud includes an interior surface and an exterior surface. The surface is coated with a silicone polyurethane polymer. The resulting surface has reduced surface energy, and can shed rain, snow, and ice more easily.Type: ApplicationFiled: June 4, 2010Publication date: February 3, 2011Applicant: FLODESIGN WIND TURBINE CORPORATIONInventors: Thomas J. Kennedy, III, Walter M. Presz, JR., Michael J. Werle

Publication number: 20110014038Abstract: A wind turbine comprises a turbine shroud and optionally an ejector shroud. The turbine shroud and/or the ejector shroud include a skeleton support structure, with a skin covering at least a portion of the turbine shroud and/or ejector shroud skeleton. In other embodiments, leading and trailing edges of the turbine shroud and/or ejector shroud are made of a rigid material and are not covered by the skin of the shroud.Type: ApplicationFiled: June 25, 2010Publication date: January 20, 2011Applicant: FloDesign Wind Turbine CorporationInventors: Michael J. Werle, William Scott Keeley, Thomas J. Kennedy, III, Walter M. Presz, JR., Robert Dold

Publication number: 20110002781Abstract: A wind turbine produces a unique pressure profile downstream of the wind turbine. This pressure profile reflects the structure of the wind turbine, which includes a shroud that has mixing lobes on a trailing edge thereof. The pressure profile includes high pressure and low pressure regions corresponding to the number and location of the mixing lobes on the shroud.Type: ApplicationFiled: June 3, 2010Publication date: January 6, 2011Applicant: FLODESIGN WIND TURBINE CORPORATIONInventors: Walter M.

Publication number: 20100316493Abstract: A Mixer/Ejector Wind Turbine (“MEWT”) system is disclosed which routinely exceeds the efficiencies of prior wind turbines. Unique ejector concepts are used to fluid-dynamically improve many operational characteristics of conventional wind turbines for potential power generation improvements of 50% and above. Applicants' preferred MEWT embodiment comprises: an aerodynamically contoured turbine shroud with an inlet; a ring of stator vanes; a ring of rotating blades (i.e., an impeller) in line with the stator vanes; and a mixer/ejector pump to increase the flow volume through the turbine while rapidly mixing the low energy turbine exit flow with high energy bypass fluid flow. The MEWT can produce three or more time the power of its un-shrouded counterparts for the same frontal area, and can increase the productivity of wind farms by a factor of two or more. The same MEWT is safer and quieter providing improved wind turbine options for populated areas.Type: ApplicationFiled: May 19, 2010Publication date: December 16, 2010Applicant: FLODESIGN WIND TURBINE CORPORATIONInventors: Walter M.

Publication number: 20100314885Abstract: A wind turbine comprises a turbine shroud and optionally an ejector shroud. The wind turbine encloses a permanent magnet ring generator. A static ring of phase windings is located in the turbine shroud, and wind airflow causes a rotor having permanent magnets thereon to rotate, creating an electric current in the static ring. The permanent magnets are arranged to form a Halbach cylinder with the magnetic field being exterior to the rotor.Type: ApplicationFiled: July 1, 2010Publication date: December 16, 2010Applicant: FLODESIGN WIND TURBINE CORPORATIONInventors: Walter M.
