Patent number: 7870739Abstract: A curved diffuser (210) in a gas turbine engine (201) directs a primary portion of air flow from a compressor (202) through a curved discharge opening (213) into a plenum (220). The curved diffuser (210) also comprises ports (217) through which a secondary portion of air passes into confined space (225) that is defined in part by a pressure boundary element that may be comprised of at least one plate (222) or at least one conduit (306). The at least one plate (222) and the at least one conduit (306) respectively comprise apertures (246, 312) through which pass the secondary portion of air to provide impingement-type cooling to transitions (230, 320). In various embodiments the velocity of the air between adjacent transitions (230, 320) may flow at relatively uniform velocity along the longitudinal distance of the respective transitions (230, 320).Type: GrantFiled: February 2, 2006Date of Patent: January 18, 2011Assignee: Siemens Energy, Inc.Inventor: Robert J.

Patent number: 7870740Abstract: An afterbody for a turbojet engine is disclosed. The afterbody includes an afterburner casing, a thermal protection liner, and a diaphragm-forming assembly interposed between the liner and the casing. The diaphragm-forming assembly defines a flow area which is traversed by a ventilation stream. The diaphragm-forming assembly includes two annular plates overlapping one another, each being perforated with a plurality of apertures and being mounted on the liner and the casing respectively. The apertures jointly define the flow area of the assembly. Furthermore, the assembly is designed such that the expansion of the liner causes an angular displacement of the plate with respect to the plate, leading to an increase in the size of the flow area.Type: GrantFiled: April 27, 2007Date of Patent: January 18, 2011Assignee: SNECMAInventors: Jacques Marcel Arthur Bunel, Thierry Andre Emmanuel Cortes, Alain Pierre Page, Fabienne Vagner

Patent number: 7870741Abstract: A method of assembling a crank assembly for a turbine engine. The turbine engine includes a valve assembly including an outer fairing and an inner fairing coupled to the outer fairing with a strut. The valve assembly further includes an annular slide valve coupled between the inner and outer fairings. The valve assembly is positioned within a duct having a radially outer duct wall and a radially inner duct wall. The method includes coupling a first arm of a crank assembly to the annular slide valve, and coupling a second arm of the crank assembly to the outer fairing such that the crank assembly controls movement of the annular slide valve and for moving the outer and inner fairings between a first operational position and a second operational position to facilitate regulating an amount of airflow channeled through the turbine engine.Type: GrantFiled: May 25, 2007Date of Patent: January 18, 2011Assignee: General Electric CompanyInventors: Donald Michael Corsmeier, David Lynn Dawson

Patent number: 7870746Abstract: Systems and methods for releasing and replacing stored energy comprise capturing inlet air from the ambient environment so the inlet air flows in a first general direction. Released liquid air flows in a second general direction, the second general direction being substantially opposite to the first general direction. The released liquid air is pumped to pressure, and the released liquid air and inlet air flow past each other such that heat exchange occurs. The inlet air warms the released liquid air such that the released liquid air is substantially vaporized, and the released liquid air cools the inlet air. Moisture and carbon dioxide are removed from the inlet air, and the inlet air is compressed and cooled such that the inlet air is substantially liquefied. The substantially liquefied air replaces a portion of the released liquid air; and the substantially vaporized released liquid air is combusted with fuel to produce electricity.Type: GrantFiled: May 27, 2008Date of Patent: January 18, 2011Assignee: Expansion Energy, LLCInventor: David Vandor
