摘要： A method for forming a liquid cooled airfoil for a gas turbine is disclosed. A plurality of holes are formed at spaced locations in an oversized airfoil blank. A pre-formed composite liquid coolant tube is bonded into each of the holes. The composite tube includes an inner member formed of an anti-corrosive material and an outer member formed of a material exhibiting a high degree of thermal conductivity. After the coolant tubes have been bonded to the airfoil blank, the airfoil blank is machined to a desired shape, such that a portion of the outer member of each of the composite tubes is contiguous with the outer surface of the machined airfoil blank. Finally, an external skin is bonded to the exposed outer surface of both the machined airfoil blank and the composite tubes.

摘要： An improved cooling system for a gas turbine is disclosed. A plurality of V-shaped notch weirs are utilized to meter a coolant liquid from a pool of coolant into a plurality of platform and airfoil coolant channels formed in the buckets of the turbine. The V-shaped notch weirs are formed in a separately machined cylindrical insert and serve to desensitize the flow of coolant into the individual platform and airfoil coolant channels to design tolerances and non-uniform flow distribution.

摘要： In accordance with embodiments of this invention, a pressure actuated leaf seal assembly is provided that includes film riding, hydrodynamic/hydrostatic runners under seal member leaf ends. Leaf seal assemblies according to embodiments of this invention maintain the runner away from a rotating body until adequate rotating speed is present to generate lift required to allow the runner to float on a thin film of operating fluid on the rotating body, so that the runner does not rub the rotating body. In addition, runners are attached, or added, to leaf seal members such that the runners move in a radial direction, while remaining parallel to the rotating body. In one embodiment, a runner can comprise a separate structure coupled to a leaf seal member, and in another embodiment, a runner can comprise a wear-resistant pad on a distal end of a leaf seal member.

摘要： A seal assembly which, among other applications, may be used for sealing fluid leakage between a steam or combustion (gas) turbine rotor and a turbine stator body. The seal assembly includes elements having a plurality of spaced leaf seal members with slots therebetween. Each leaf seal member is angled out-of-plane between a fixed end and a free end thereof, and the free ends slidably engage the rotatable component. In one embodiment, the fixed ends of each leaf seal member are positioned substantially perpendicular to a longitudinal axis of the rotating component. A support may be provided supporting the free end such that it contacts a distal end of the support in an operative state and is out of contact with the distal end in an inoperative state. Seal members may include two different materials having different coefficients of thermal expansion.

摘要： An improved cooling system utilizes flow resistant devices distributing liquid coolant to air foil coolant channels in a bucket of a turbine. A separate flow resistance device associated with each of the air foil coolant channels resist the flow of liquid coolant into the coolant channels whereby a fluid head is developed in a standpipe upstream of the flow resistance devices. The fluid head, together with the outward radial acceleration meters the flow of fluid through each flow resistance device according to the head. In the disclosed embodiments, the flow resistant devices alternately take the form of a tortuous passage, an orifice and a plurality of vortex flow chambers.

The flame holding portion and any other portion where air is introduced into the combustor are made of metal while insulated, imperforate ceramic construction is used for the balance of the combustor liner. In this manner the regions of high local stress are accommodated by cooled metal and the regions of uniform thermal stress are accommodated by resiliently-mounted thermally-insulated ceramic.
