摘要： A gas turbine nozzle segment has outer and inner bands. Each band includes a side wall, a cover and an impingement plate between the cover and nozzle wall defining two cavities on opposite sides of the impingement plate. Cooling steam is supplied to one cavity for flow through apertures of the impingement plate to cool the nozzle wall. The side wall of the band and inturned flange define with the nozzle wall an undercut region. The inturned flange has a plurality of apertures for directing cooling steam to cool the side wall between adjacent nozzle segments.

摘要： A cooling architecture for flanges of a steam turbine casing, which effectively cools the flanges coupled by bolts to prevent the leakage of the steam caused by a decrease of the fastening force of the bolts. An upper casing 10 and a lower casing 11 are joined together at flanges 12 and 13 which are fastened and secured by bolts to hermetically seal a steam turbine. Pipes 20 are secured so as to be contacted to the peripheral of the flanges 12 and 13, and a side heat insulator 15a is fitted thereto from the outer side. Each pipe 20 is arranged corresponding to each bolt, or a plurality of pipes are arranged corresponding to each bolt 14. The flanges 12 and 13 are heated by the internal high-temperature steam, the ambient air 30 is introduced into the pipe 20 from the lower end thereof due to the natural convection thereby to cool the flanges 12, 13 and the bolts 14. Accordingly, a decrease of the fastening force of the bolts, and steam leakage, hardly occur.

摘要： An assembly that includes a CMC article, and a method of forming the assembly, so as to reduce the likelihood during a transient thermal condition of the CMC article becoming interlocked with the worn shank of a fastener used to secure the article to its support structure. The CMC article has oppositely-disposed first and second surfaces, a hole through the article and intersecting the first and second surfaces so as to define oppositely-disposed first and second openings at the first and second surfaces, respectively, and continuous chamfers along the entirety of the first and second openings. The assembly further includes a support structure adjacent the article, and a fastener received in the hole of the CMC article and securing the CMC article to the support structure. The location of the chamfers at the perimeter of each opening eliminates a relatively sharp edge that could interlock with the worn shank of the fastener during a thermal excursion.

摘要： A turbine vane assembly which includes an outer endcap having a plurality of generally straight passages and passage segments therethrough, an inner endcap having a plurality of passages and passage segments therethrough, and a vane assembly having an outer shroud, an airfoil body, and an inner shroud. The outer shroud, airfoil body and inner shroud each have a plurality of generally straight passages and passage segments therethrough as well. The outer endcap is coupled to the outer shroud so that outer endcap passages and said outer shroud passages form a fluid circuit. The inner endcap is coupled to the inner shroud so that the inner end cap passages and the inner shroud passages from a fluid circuit. Passages in the vane casting are in fluid communication with both the outer shroud passages and the inner shroud passages. Passages in the outer endcap may be coupled to a cooling system that supplies a coolant and takes away the heated exhaust.

摘要： A turbine casing includes a multilayer casing wall in which an intermediate layer in the form of a non-metallic bulk material, preferably sand, is provided between an inner layer and an outer layer, to cope with high steam states. A method of manufacturing a multilayer turbine casing includes inserting a core representing an intermediate layer into a casting mold while forming a cavity for the inner layer and/or the outer layer. The cavity is then filled with a casting material, with the core expediently remaining as the intermediate layer in the casing wall. Alternatively, first of all a U-shaped profile part is made and an intermediate space formed by the outer layer and the inner layer is filled with the bulk material.

摘要： A heat dissipation fan having a side mount configuration includes a casing having a bottom wall and a surrounding side wall extending from the bottom wall to define an open top. The side wall also defines a side opening to guide an air flow toward a heat source. A cross bar is detachably mounted to the open top or is made of resilient material. A shaft is arranged inside the casing and has upper and lower ends removably received in a recess defined in the cross bar and a notch defined in the bottom wall of the casing. A blade assembly comprised of a cylinder and blades extending from the cylinder is rotatably mounted to the shaft. Windings and magnets are arranged inside the cylinder. Electrical wires are electrically connected to the windings via conductive pads formed on the upper end of the shaft or by extending through openings defined in the upper end of the shaft. No control circuit is included in the casing, the distance between the blades and the bottom wall can be substantially reduced and the structure is simplified.

摘要： Gas turbine engine components which are supplied with longitudinal ribs on the areas that are in contact with a gas flow, whereby the riblets have a length of at least 5 mm, a height of at least 0.02 mm and a width of at least 0.01 mm. Those riblets are applied using the High Velocity Oxyfuel Process (HVOF). Using this technique material in the form of a powder is applied at high velocity onto the substrate of the gas turbine engine components with the riblets created preferably by positioning a mask in front of the subject part. If necessary, prior to the application of the HVOF coating, a bondcoat can be applied on the subject parts.
