| 20090324399 | Reverse curved nozzle for radial inflow turbines - A nozzle for radial inflow turbines having an outer surface having a concave shape, and an inner surface having a non-concave, i.e. straight or convex, shape. Also a leading edge may have a hole that is capable of receiving a fastener to secure the nozzle vane to an assembly housing. | 12-31-2009 |
| 20110058936 | TURBINE DUCT ARRANGEMENT - A wind turbine duct arrangement having a plurality of frusto-conical ducts each having an open apex and an open base defining an air intake, the ducts radially joined at their apexes to define a convergence zone wherein operatively rotating blades of a turbine may be installed transverse to the plurality of ducts. In use, the turbine duct arrangement provides a combination catchment and channelling area through the open bases of the plurality of ducts for channelling wind intake through the arrangement onto blades of a wind turbine transversely installed in the convergence zone defined by the radially joined apexes of the plurality of ducts. | 03-10-2011 |
| 20120121398 | Wind Turbine Utilizing Wind Directing Slats - Various embodiments of a wind turbine are disclosed having a support structure with a rotor disposed about the support structure and having first and second scoops. Each of the scoops can have medial and lateral openings, and the medial opening can include a plurality of apertures that remain open during a complete rotation of the rotor. | 05-17-2012 |
| 20140234094 | TURBOMACHINES HAVING GUIDE DUCTS - Turbomachines having guide ducts are disclosed. One disclosed example turbomachine includes a rotor rotatable about an axis of rotation and having rotor blade ducts, a housing having housing ducts to allow the inflow or outflow of working medium and guide blade ducts fixed in the housing, where the rotor blade ducts are in fluid communication with the housing ducts via the guide blade ducts. | 08-21-2014 |
| 20140271157 | FAN CONTAINMENT SYSTEM - A fan containment system arranged to be fitted around an array of radially extending fan blades mounted on a hub in an axial gas turbine engine. Each fan blade has a respective tip. The system includes: a cylindrical fan case including a hook projecting in a radially inward direction and positioned axially forward of the radial array of fan blades; a fan track liner disposed on the radially inner surface of the fan case; and a damaging tool which projects radially inwards from the fan case towards the tips. The damaging tool has a tip radially outward of the fan blade tips. The damaging tool is configured that in the event that one of the fan blades is released from the hub, the tip of the damaging tool damages the fan blade tip of the released fan blade to promote penetration of the fan blade into the fan track liner. | 09-18-2014 |
| 20140356148 | RADIAL VANE AND METHOD OF MANUFACTURING SAME - Provided is a radial vane with which manufacturing is possible with superior economy, without incurring a cut loss associated with vane separation in a weld part of a thread bundle With a longitudinal intermediate part of a contiguous bundle of threads being a fold-over part, both end parts of the fold-over part of the thread bundle are opened into radial shapes and superpositioned, leaving a space in the center part of the fold-over part, a ring-shaped fold-over part ( | 12-04-2014 |
| 415187000 | Plural, axially spaced sets of distributors | 4 |
| 20110189001 | ROTATABLE VANED NOZZLE FOR A RADIAL INFLOW TURBINE - A variable nozzle system can comprise a gas inlet ring, an opposing gas outlet ring, an actuation ring, guides, and vanes circumferentially spaced about and disposed between the gas inlet ring and the gas outlet ring. The gas inlet ring, the gas outlet ring, and the vanes can form nozzles, the nozzles being variable by rotation of the vanes about a pivot axis. The plurality of guides can extend from the gas inlet ring, the gas outlet ring, or the actuation ring, and the vanes can be connected to the actuation ring, so that each vane can be rotated by rotation of the actuation ring and by sliding against a respective guide from the plurality of guides. The actuation ring can have a gear rack and can be rotated by rotatable engagement of the gear rack with a pinion attached to the end of a rotatable gear shaft. | 08-04-2011 |
| 20120328425 | DOUBLE TUNNEL WIND TURBINE - A wind turbine apparatus includes a shaft carrying a plurality of rotor wheels fixed at axially spaced intervals. Each rotor wheel includes buckets at the periphery thereof. First and second generally cylindrical housing are disposed in concentric relationship to define a blind annular chamber surrounding the rotor wheels that directs ambient winds to through the inner wall of the inner cylindrical housing to the periphery of the respective rotor wheels. One extremity of the blind annular chamber is open for receiving ambient air flow and a second axial extremity proximate is closed, whereby axial airflow into the annular chamber is substantially directed in a radial direction by the toward the buckets carried on the rotor wheels to cause rotation of the shaft. | 12-27-2012 |
| 20150063991 | TURBINE - A turbine, including: a volute and an impeller. The volute includes: a volute gas inlet, a volute gas feeding flow passage, and a volute gas outlet. The impeller includes: blades, an impeller gas feeding flow passage, an impeller gas inlet, an impeller gas outlet, and a partition plate. The impeller gas feeding flow passage includes: an inner flow passage and an outer flow passage. The impeller is disposed inside the volute. The blades are disposed on an outer part of the impeller. The partition plate is circumferentially disposed between the impeller gas inlet and the impeller gas outlet. The partition plate divides the impeller gas feeding flow passage into the inner flow passage and the outer flow passage. | 03-05-2015 |
