20110091323 | COMPRESSOR HOUSING FOR TURBOCHARGER - A compressor impeller | 04-21-2011 |
20120128496 | WIND ENERGY USE - The invention provides wind energy use. One application provides wind energy use for water harvesting from natural humid air. The method is based on changing thermodynamic state properties of ambient airborne wind passed through a convergent-divergent system. The device comprises a cascade of sequentially arranged wind converging and wing-like components. Those components transform the wind into fast, cooled, out-flowing air portions. The decrease in static pressure and temperature triggers condensation of water-vapor into water-aerosols. Another application of the method provides an effective mechanism for harvesting electrical energy from naturally warm air using renewable wind energy, including the wind inertia, internal heat, and potential energy stored in the air mass in the Earth's gravitational field. The electrical energy harvesting mechanism is also applicable to use of natural renewable energy of streaming water. | 05-24-2012 |

20130272882 | AXIALLY-SPLIT RADIAL TURBINES AND METHODS FOR THE MANUFACTURE THEREOF - Embodiments of an axially-split radial turbine, as are embodiments of a method for manufacturing an axially-split radial turbine. In one embodiment, the method includes the steps of joining a forward bladed ring to a forward disk to produce a forward turbine rotor, fabricating an aft turbine rotor, and disposing the forward turbine rotor and the aft turbine rotor in an axially-abutting, rotationally-fixed relationship to produce the axially-split radial turbine. | 10-17-2013 |
20140072432 | BLADE ARRANGEMENT FOR A TURBO ENGINE - A blade arrangement for a turbo engine, in particular a gas turbine, with a rotor and several blades fastened thereto, which are configured to be systematically different, wherein at least two adjacent blades have systematically different shrouds ( | 03-13-2014 |
20150037153 | Cross Flow Turbine with Straight Vertical and Helical Slanted Blades - A structural duct apparatus includes a cross flow turbine for use in a fluid flow. The turbine has at least one straight vertical aerofoil blade and at least one helical aerofoil blade slanted toward the direction of rotation. Inner and outer walls of the duct apparatus provide an inner diffuser flow passageway that houses turbine power take off modules with the outer surfaces of the duct influencing flow direction so that where there are at least two ducts an open flow barrage is advantageously formed. | 02-05-2015 |
20150300177 | BLADE HAVING A DIVIDED SHAFT AND BLADE UNIT UTILIZING THE BLADE AND METHOD FOR MAKING THE BLADE UNIT - A method for making blade unit with divided shaft facilitating drastically the productivity and assembling compared to a method fixing blade to a shaft using many connecting parts. The method for making blade unit includes steps for making a blade with divided shaft comprising a blade and a divided shaft that is attached integrally to a root portion of the blade and divided into a plurality of portions in a direction of length of the shaft, and combining a plurality of made blades with divided shaft together with one another through the divided shaft. | 10-22-2015 |
20160159458 | PROPELLER - A propeller includes a hub coaxially surrounding a longitudinal axis. A ring shroud coaxially surrounds the longitudinal axis and is spaced radially from the hub. At least one propeller blade is fixedly attached to both the hub and ring shroud and extends radially therebetween for mutual rotation therewith. At least one stub blade has a first stub end radially spaced from a second stub end. The first stub end is fixedly attached to a selected one of the hub and ring shroud. The second stub end is cantilevered from the first stub end and is radially interposed between the first stub end and the selected one of the hub and ring shroud. | 06-09-2016 |
