Abstract

A vane array adapted to be coupled to a vane carrier within a gas turbine engine is provided comprising: a plurality of elongated airfoils comprising at least a first airfoil and a second airfoil located adjacent to one another; a U-ring; first connector structure for coupling a radially inner end section of each of the first and second airfoils to the U-ring; second connector structure for coupling a radially outer end section of each of the first and second airfoils to the vane carrier; a platform extending between the first and second airfoils; and platform connector structure for coupling the platform to one of the U-ring and the vane carrier.

Turbine blade and non-integral platform with pin attachment

Patent Campbell, Christian Xavier; Eng, Darryl; Marra, John J.

Platforms (36, 38) span between turbine blades (23, 24, 25) on a disk (32). Each platform may be individually mounted to the disk by a pin attachment (42). Each platform (36) may have a rotationally rearward edge portion (50) that underlies a forward portion (45) of the adjacent platform (38). This limits centrifugal bending of the rearward portion of the platform, and provides coolant sealing. The rotationally forward edge (44A, 44B) of the platform overlies a seal element (51) on the pressure side (28) of the forwardly adjacent blade, and does not underlie a shelf on that blade.

Gas turbine vane platform element

Patent Campbell, Christian X [Oviedo, FL]; Schiavo, Anthony L [Oviedo, FL]; Morrison, Jay A [Oviedo, FL]

A gas turbine CMC shroud plate (48A) with a vane-receiving opening (79) that matches a cross-section profile of a turbine vane airfoil (22). The shroud plate (48A) has first and second curved circumferential sides (73A, 74A) that generally follow the curves of respective first and second curved sides (81, 82) of the vane-receiving opening. Walls (75A, 76A, 77A, 78A, 80, 88) extend perpendicularly from the shroud plate forming a cross-bracing structure for the shroud plate. A vane (22) may be attached to the shroud plate by pins (83) or by hoop-tension rings (106) that clamp tabs (103) of the shroudmore » « less

Non-vaned swirl core configurations

Patent Siebert, Brett W.

A non-circular coolant passage is disclosed, which includes one or more walls axially defining a flow path; an inlet connecting to a first end of the flow path; and an exit connecting to a second end of the flow path, wherein a size of a passage cross-section varies in the axial direction. In certain exemplary embodiments the passage cross-section size varies uniformly, while in others the passage cross-section size varies incrementally. In certain exemplary embodiments, an angular orientation of the passage cross-section varies in the axial direction. The cross-section angular orientation can vary uniformly, incrementally, or a combination of both.more » « less
