| 20090053037 | TURBINE VANES WITH AIRFOIL-PROXIMATE COOLING SEAM - Aspects of the invention relate to a turbine vane in which the inner and outer platforms are located substantially entirely on either the pressure side or the suction side of the airfoil. When a plurality of such vanes are installed in the turbine, a seam is formed by the circumferential end of the inner and outer platforms and a portion of the airfoil of a neighboring vane. During engine operation, a high pressure coolant is supplied to at least one of the platforms. The coolant can leak through the seam. Because the seam is located proximate the airfoil, the coolant leakage through the seam can be productively used to cool the transition region between the vane platforms and the airfoil. In addition to such cooling benefits, aspects of the invention can result in a potential increase in engine efficiency as well as component life. | 02-26-2009 |

| 20120009055 | REACTION-TYPE TURBINE - The present invention relates to a reaction-type turbine. The reaction-type turbine of the present invention is configured such that a jet and rotating unit and a turbine shaft rotate by the repulsive force generated when steam spurts from the jet and rotating unit, so as to generate propulsion force. Thus, the operating stability of a steam turbine can be maintained even when condensate water is mixed with the steam, and manufacturing costs can be significantly reduced. Further, in order to reduce a loss of energy, the flow resistance of the steam is remarkably reduced or pressure leakage is prevented, thereby obtaining a low-cost and high-efficiency turbine. | 01-12-2012 |

| 20130156546 | REACTION-TYPE TURBINE - According to the present invention, a reaction-type turbine includes: a housing including a housing passage between an inlet and an outlet; a turbine shaft rotatably coupled to the housing to transmit torque; and at least one nozzle assembly coupled to the turbine shaft and rotatably provided in the housing passage. The nozzle assembly includes circumferential injection holes therein for injecting a high-pressure fluid in a circumferential direction and generating torque. Accordingly, when turbines having different capacities are manufactured, common parts can be compatibly used and assembling efficiency is improved. In addition, the eccentric rotation of the turbine shaft is prevented to significantly improve the durability of the reaction-type turbine. Furthermore, since the injection holes are long, the reaction-type turbine can be miniaturized and the efficiency thereof is improved. | 06-20-2013 |
| 20140133961 | METHOD AND DEVICE FOR PRODUCING A DRIVING FORCE BY BRINGING ABOUT DIFFERENCES IN A CLOSED GAS/LIQUID SYSTEM - The invention relates to a method for producing a continuous driving force by providing kinetic energy of a liquid medium by means of bringing about differences in pressure in a closed system that is filled with liquid medium, in particular water, and gaseous medium, in particular air, and relates to a device for implementing the method, wherein the device consists of a vessel ( | 05-15-2014 |
| 20140154052 | WIND AEOLIPILE - Described herein is essentially a high-efficiency, hybrid fluid-aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid-flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle-effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle-effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency, than is possible in conventional blade-type wind turbines. | 06-05-2014 |

The runner has an introduction pipe that rises upward from an opening at the center of a bottom face to introduce high-pressure water; first guide pipes that extend radially from around the introduction pipe; and first injection nozzles provided at the tips of the first guide pipes, wherein the reactive force of the high-pressure water injected is utilized to turn the runner. | 07-03-2014 |
