Turbine stator vane segment having internal cooling circuits

Patent Jones, Raymond Joseph [Oxford, MA]; Burns, James Lee [Schenectady, NY]; Bojappa, Parvangada Ganapathy [Simpsonville, SC]; ...

A turbine stator vane includes outer and inner walls each having outer and inner chambers and a vane extending between the outer and inner walls. The vane includes first, second, third, fourth and fifth cavities for flowing a cooling medium. The cooling medium enters the outer chamber of the outer wall, flows through an impingement plate for impingement cooling of the outer band wall defining in part the hot gas path and through openings in the first, second and fourth cavities for flow radially inwardly, cooling the vane. The spent cooling medium flows into the inner wall and inner chambermore » « less

Double-stator electromagnetic pump having alignment ring and spine assembly

Patent Fanning, Alan Wayne [San Jose, CA]; Olich, Eugene Ellsworth [Aptos, CA]; Dahl, Leslie Roy [Livermore, CA]; ...

A support structure for clamping the inner coils and inner lamination rings of an inner stator column of an electromagnetic induction pump to prevent damaging vibration. A spine assembly, including a base plate, a center post and a plurality of ribs, serves as the structural frame for the inner stator. Stacked alignment rings provide structure to the lamination rings and locate them concentrically around the spine assembly central axis. The alignment rings are made of a material having a high thermal expansion coefficient to compensate for the lower expansion of the lamination rings and, overall, provide an approximate match tomore » « less

Ceramic-to-metal stator vane assembly with braze

Patent Chase, Donna J [Scottsdale, AZ]; Fang, Ho T [Scottsdale, AZ]; Irwin, Craig W [Tempe, AZ]; ...

A stator vane assembly for a gas turbine engine that includes a plurality of circumferentially spaced ceramic vanes, each of which has an inner and outer ceramic shroud, and a ceramic post extending from one of the shrouds, and a metallic platform having a plurality of circumferentially spaced recesses. The posts are inserted into a metallic sleeve and then brazed. The brazed sleeves are then mounted in the recesses. A method for assembling these components to form the stator assembly is also described.
