Patent number: 9408287Abstract: A plasma actuator system includes a first electrode having a first slit formed in a first peripheral section of the first electrode. The first slit directs flow of a gaseous medium along a radial direction of the first electrode. Further, the plasma actuator system includes a second electrode coupled to the first electrode and is disposed concentrically around the first electrode. The second electrode includes a second slit formed in a second peripheral section for directing flow of the gaseous medium along the radial direction. Further, the system includes a power source coupled to the first and second electrode for supplying electric power to the electrodes for ionizing gaseous medium to generate plasma.Type: GrantFiled: November 27, 2012Date of Patent: August 2, 2016Assignee: General Electric CompanyInventors: Dmytro Floriyovych Opaits, Seyed Gholamali Saddoughi

Patent number: 9353729Abstract: An aerodynamic hub assembly for a wind turbine is disclosed. The hub assembly may include a hub extension, a rotor blade having a blade root and a blade tip, and a hub airfoil section mounted at least partially over the hub extension. The hub airfoil section may be fixed relative to the rotor blade or may be configured to rotate about a common pitch axis with the rotor blade. The hub extension may be connected to and extend radially from a center of the hub assembly. Further, the hub assembly may include a pitch bearing having an inner race and an outer race, wherein the pitch bearing may be coupled between the hub extension and the blade root. Additionally, the hub assembly may also include an aerodynamically-shaped spinner, wherein the spinner may house at least a portion of a root structure extending radially from the center of the hub assembly.Type: GrantFiled: July 2, 2013Date of Patent: May 31, 2016Assignee: General Electric CompanyInventors: Ian David Wilson, Kevin Wayne Kinzie, James Henry Madge, Daniel Jason Erno, Michael Colan Moscinski, Zaeem Ashraf Khan, Dmytro Floriyovych Opaits

Patent number: 9194363Abstract: A deployable aerodynamic component configured to be mounted to a wind turbine. The wind turbine includes at least one rotor blade. The deployable aerodynamic component configured to be positioned in front of an inner portion of the at least one rotor blade, and is structurally configured to cover a substantial portion of the inner portion of the at least one rotor blade in a wind direction during deployment of the deployable aerodynamic component and to allow the passage therethrough of an incoming wind when non-deployed. Further described is a wind turbine including the above-described deployable aerodynamic component and method for aerodynamic performance enhancement of an existing wind turbine, wherein the method includes mounting the above-described deployable aerodynamic component to a wind turbine.Type: GrantFiled: June 29, 2012Date of Patent: November 24, 2015Assignee: General Electric CompanyInventors: Dmytro Floriyovych Opaits, Seyed Gholamali Saddoughi, Grover Andrew Bennett, Jr., Matthew Patrick Boespflug, Stephen Bertram Johnson, Peggy Lynn Baehmann, Anurag Gupta

Patent number: 9162754Abstract: A method for actively manipulating a primary fluid flow over a surface using an active flow control system including an active fluid flow device to provide lift enhancement and lift destruction. The method including the disposing of an active fluid flow device in the surface. The active fluid flow device is then operated to generate at least one of a steady blowing secondary fluid flow, a pulsed secondary fluid flow or an oscillating secondary fluid flow. While flowing the primary fluid over the surface to create a primary flow field, a secondary fluid flow is injected in an upstream direction and substantially opposed to the incoming primary fluid flow. The injecting of the secondary fluid flow in this manner provides for influencing of the primary flow field by manipulating a momentum of the secondary fluid flow to influence the incoming primary fluid flow and resultant lift.Type: GrantFiled: April 27, 2012Date of Patent: October 20, 2015Assignee: General Electric CompanyInventors: Matthew Patrick Boespflug, Seyed Gholamali Saddoughi, Grover Andrew Bennett, Jr., Dmytro Floriyovych Opaits

Patent number: 9038920Abstract: An electro-hydrodynamic wind energy conversion system is presented. The system includes a wind passage allowing wind flow. Further, the system includes a reservoir having an opening in communication with the wind passage and configured to hold a liquid. The system also includes an agitator coupled to the reservoir and configured to convert the liquid into droplets. Additionally, the system includes a charging system disposed substantially opposite the reservoir opening and configured to deposit an electrostatic charge on the droplets and draw the droplets into the wind passage. Moreover, the system includes a charge collector disposed at a distal end of the wind passage and configured to collect the electrostatic charge from the droplets.Type: GrantFiled: December 21, 2011Date of Patent: May 26, 2015Assignee: General Electric CompanyInventors: Chiranjeev Kalra, Charles Erklin Seeley, Dmytro Floriyovych Opaits, Sunilkumar Onkarnath Soni, Gary Lee Leonard
