Abstract: The object of this invention is to create the elements necessary to supply lifting energy in flowlines or recipients containing motionless fluids. The invention provides a motive force through hollow shafts or hollow stators inside a streamlined housing having a rotor comprised of two concentric and coplanar arrays of external and internal blades working together as pump and turbine on the same plane. To operate, the artifact requires a source of fluid supply acting as motive fluid to boost a static or relative slow-motion fluid. The motive fluid travels from an internal hollow shaft toward an external hollow shaft, or from a scroll case throughout hollow stators to an internal array of blades to induce movement on the rotor. The present invention is designed to be used in different locations for different applications in different positions, to support the transportation of fluids. It operates with any fluid supply such as gas or liquid or a mix of both.

Abstract: A wind power system including a wind turbine affixed to a support tower, and a wind deflector deployable relative to a direction of air flow and configured to control the movement of at least a portion of air flow passing through rotor blades of the wind turbine to reduce wind loads on the components of the wind turbine while maintaining the air flow in an operating power production range.

Abstract: A BOAS segment for a turbine includes an impingement cavity with circular cooling air supply holes adjacent to a leading edge side of the cavity and is connected to main body axial cooling holes that open onto the trailing edge side of the BOAS segment. Cooling supply holes are located at the four corners of the impingement cavity and are connected to multiple cooling holes that open onto both edges of the segment in that corner. Thin metering cooling slots are positioned along the mate face sides in the cavity and are each connected to multiple cooling holes that discharge cooling air onto the mate face edges.

Abstract: A platform cooling structure for a gas turbine moving blade is provided which is capable of improving cooling performance of a platform and of improving reliability of a moving blade in such a manner that a portion in the vicinity of a side edge of the platform which is away from moving blade cooling passageways and is easily influenced by thermal stress caused by high-temperature combustion gas, that is, an upper surface of the side edge is effectively cooled by guiding high-pressure cooling air, flowing to the moving blade cooling passageways, to a discharge opening formed in a surface of the platform in the vicinity of the side edge of the platform without particularly attaching an additional member such as a cover plate to the platform. A moving blade cooling passageway 17c is formed in the inside of the gas turbine moving blade.

Abstract: A rotor blade suitable for use in a gas turbine engine includes an attachment section which defines at least one internal cooling passage along a passage axis through the attachment section.

Abstract: An aero-engine nose cone anti-icing system (10) using a rotating heat pipe (12) is provided to replace the current method of blowing hot compressor bleed air over the nose cone surface. Heat is transferred from a hot source (36) within the engine (22) to the nose cone (18) through a rotating heat pipe (12) along the central shaft (16). A condenser (20) and evaporator (14) are provided which are adapted to the heat transfer requirements and space constraints in the engine (22).

Abstract: A rotary pressure transfer device utilizes a multi-channel, generally cylindrical rotor (15) that revolves with its flat end faces juxtaposed with flat end surfaces of a pair of flanking end covers (19, 21) in which inlet and outlet passageways are provided. The design is such that there are only oblique ramps (65) in the passageways on the high pressure side which create directional flow of liquid to cause rotor revolution in the desired direction. Passageways (27a, 27b) on the low pressure side may be shaped so that there is essentially axial or longitudinal flow entry and discharge of liquid between the channels and the passageways, or passageways (71) may be constructed to create directional flow that slightly retards rotor revolution in such desired direction.

Abstract: In a supercharger (10) with an electric motor in accordance with the invention, an inner side of the center housing (10) is provided with an air introduction path (38) introducing a part of a compressed air within the compressor housing (8) to the electric motor (20), and a cooling structure portion (40) cooling the air flowing through the air introduction path (38). The center housing (14) has a cooling fluid flow path (34) which is formed so as to surround the electric motor (20) and puts a cooling fluid for cooling the electric motor (20) in circulation inside. The cooling structure portion (40) is structured such as to be capable of heat exchanging between the cooling fluid and the air flowing through the air introduction path (38).

A number of horizontal beams connect each adjacent pair of columns together beneath the roof. Each of the beams has an inner surface and an opposed, outer surface. A plurality of movable panels is suspended from the horizontal beams. Each of the panels is hingedly connected, at the top thereof, to one of the beams and, at the bottom thereof, normally contacts and presses downwardly upon the inner surface of another one of the beams whereby passing winds swing the bottoms of the panels inwardly and enter the wind collector.

The electric motor (20) is cooled by the first cooling structure portion (38). The diffuser portion (25) is cooled by the second cooling structure portion (39).

Abstract: A turbine impeller pump particularly for use in a geothermal pumping system has a casing with a hollow cylindrical stator or axle fixedly connected in the longitudinal axis thereof which stator or axle defines a flow passage for motive fluid and enables a rotor assembly to be rotatably mounted thereon. The rotor has spaced composite impellers which lie in assembled position in medially disposed pumping chambers in the casing having a suction inlet for fluid to be pumped and a discharge outlet for pumped fluid. The rotor further has first and second multi-stage axial flow driving assemblies disposed on opposite sides of the spaced composite impellers so that the motive fluid for driving the same can be passed to the respective adjacent composite impellers and delivered with the fluid being pumped.
