摘要： A turbine airfoil (22E-H) extends from a shank (23E-H). A platform (30E-H) brackets or surrounds a first portion of the shank (23E-H). Opposed teeth (33, 35) extend laterally from the platform (30E-H) to engage respective slots (50) in a disk. Opposed teeth (25, 27) extend laterally from a second portion of the shank (29) that extends below the platform (30E-H) to engage other slots (52) in the disk. Thus the platform (30E-H) and the shank (23E-H) independently support their own centrifugal loads via their respective teeth. The platform may be formed in two portions (32E-H, 34E-H), that are bonded to each other at matching end-walls (37) and/or via pins (36G) passing through the shank (23E-H). Coolant channels (41, 43) may pass through the shank beside the pins (36G).
摘要翻译：涡轮机翼（22E-H）从柄（23E-H）延伸。平台（30E-H）支架或围绕柄部（23E-H）的第一部分。相对的齿（33,35）从平台（30E-H）横向地延伸以与盘中的相应的槽（50）接合。相对的齿（25,27）从在所述平台（30E-H）下方延伸的所述柄（29）的第二部分横向延伸，以接合所述盘中的其它狭槽（52）。因此，平台（30E-H）和柄（23E-H）通过其相应的齿独立地支撑它们自己的离心载荷。平台可以形成为两个部分（32E-H，34E-H），它们在通过柄（23E-H）的匹配端壁（37）和/或通孔销（36G）处彼此结合。冷却剂通道（41,43）可以穿过销（36G）旁边的柄。

摘要： The outer air seal of a gas turbine engine is continuously cooled by compressor discharge air (primary) and a by-pass line (secondary) which can be throttled or shut off, augments cooling during high power conditions and is throttled or shut off at reduced power conditions, allowing the casing scrubbed by fan discharged air to shrink and reduce the clearance of the tips of the turbine blades. The air from the continuous flow (primary) line is routed to the outer air seals in a manner to avoid scrubbing the engine case.

摘要： A turbine blade with a spar and shell construction in which the spar and the shell are both secured within two platform halves. The spar and the shell each include outward extending ledges on the bottom ends that fit within grooves formed on the inner sides of the platform halves to secure the spar and the shell against radial movement when the two platform halves are joined. The shell is also secured to the spar by hooks extending from the shell that slide into grooves formed on the outer surface of the spar. The hooks form a serpentine flow cooling passage between the shell and the spar. The spar includes cooling holes on the lower end in the leading edge region to discharge cooling air supplied through the platform root and into the leading edge cooling channel.

摘要： A thermal mechanical fatigue test rig for testing a coating, such as a thermal barrier coating, under high temperature and pressure to simulate the actual operating environment of the coating. The test rig includes a combustor to produce a hot gas flow, a hollow test specimen on which the coating is placed, and a sapphire vessel that encloses the hollow test specimen to form a hot gas flow path over the coating. The sapphire vessel is clear so that the coating can be observed by a camera during the testing. An exhaust plenum is formed around the sapphire vessel to collect the exhaust form the hot gas flow in which additional cooling air and water for quenching can be injected to reduce the temperature of the hot gas flow prior to discharge from the test rig.

A fiber metal strip component (309) may be attached to the flattened portion (305) to define a first engagement surface adapted to engage an upstream side (336) of an outer vane seal rail (337), and a second engagement surface 308, adjacent the free edge (307), provides an opposed wear surface adapted to engage a downstream side (338) of the outer vane seal rail (337). System embodiments also are described, in which such transition-to-turbine seal (300) is isolated from a hot gas path (350) by provision of a plurality of cooling apertures (327) in the transition (325).

摘要： A turbine blade with a spar and shell construction in which the spar includes a blade tip and a dove-tail on the root end of the spar. A pair of platform halves form a fir-tree attachment capable of sliding into an attachment slot formed within a rotor disk. The platform halves form a slot within the fir-tree configuration that will pinch the dovetail slot of the spar and secure the spar to the platform halves against radial displacement. The shell is secured between the spar tip and the platform of the platform halves when assembled together. The spar includes cooling air passages and impingement cooling holes to provide backside impingement cooling of the shell. A fastener secures the two platform halves together so that the spar and shell blade assembly can slide into the attachment slot within the rotor disk.

摘要： A turbine airfoil (22E-H) extends from a shank (23E-H). A platform (30E-H) brackets or surrounds a first portion of the shank (23E-H). Opposed teeth (33, 35) extend laterally from the platform (30E-H) to engage respective slots (50) in a disk. Opposed teeth (25, 27) extend laterally from a second portion of the shank (29) that extends below the platform (30E-H) to engage other slots (52) in the disk. Thus the platform (30E-H) and the shank (23E-H) independently support their own centrifugal loads via their respective teeth. The platform may be formed in two portions (32E-H, 34E-H), that are bonded to each other at matching end-walls (37) and/or via pins (36G) passing through the shank (23E-H). Coolant channels (41, 43) may pass through the shank beside the pins (36G).

摘要： A turbine blade for a gas turbine engine, in which the turbine blade includes an airfoil portion with a root having a dovetail shape, and two platform halves that include a dovetail shaped opening within the platform halves to secure the blade root within the platform halves when fastened together. The platform halves have an outer fir tree shaped surface so that the blade assembly can be inserted into a slot within a rotor disk. the blade is uncoupled from the platform in the invention so that the airfoil can be made from a single crystal material with low casting defects because the platform is not cast with the airfoil. the two platform halves include the openings with side walls that are curved to follow the contour of the airfoil root so that the airfoil is secured within the platform halves against all directions of movement. An annular groove extends around the platform opening to provide for a seal to produce a seal between the high pressure cooling air supply passage within the platform and the lower pressure hot gas flow passing through the blade.
