摘要： Disclosed are a casing arrangement and a method to reduce vibrations in a gas turbine casing. The casing arrangement includes a turbine exhaust cylinder connected to a turbine exhaust manifold establishing a fluid flow path, the fluid flow path including an inner and an outer flow path. A damping blanket damps the vibrations and is coupled to a surface of the inner flow path via a constraining layer.

摘要： A vane carrier assembly is provided for supporting vanes within a main engine casing of a gas turbine engine. The vane carrier assembly comprises a plurality of vane support panels positioned adjacent to one another so as to define a vane support assembly. The support panels are assembled such that the support panels expand circumferentially to minimize radial expansion of the vane support assembly during operation of the gas turbine engine. A control ring is coupled to the main engine casing, and the vane support assembly is coupled to the control ring. The control ring may be formed from a material having a coefficient of thermal expansion less than that of the material from which the vane support assembly is formed.

摘要： A flange (28A-C, 28E, 30A-E) with a primary contact surface (29B-C, 31B-D) that is curved (C) in a section plane (P) normal to a direction of the flange around a perimeter (60) of a component. The curve may have a maximum departure (D), from a straight line drawn between the ends (34, 35) of the curve, of at least 5% of a length of the straight line. The curve may be a circular arc with a span angle (A) of at least 40 degrees. The primary contact surface (29C, 31C) may be defined by an annular portion of a torus. Alternately, the primary contact surface (31D) may follow a non-circular perimeter path. A toric or other non-planar flange interface (32A-B) may be formed by mating contact surfaces on first (22, 36) and second (24, 38) components.

摘要： An electrode (10) is presented including a sheath (14) formed of a ductile material, an outer coating (16) including a flux material, and a core (12) including at least one of flux material and alloying material. The ductile material may be an extrudable subset of elements of a desired superalloy material and the alloying material may include elements that complement the ductile material to form a desired superalloy material when the electrode is melted. The outer coating may be formed of a flexible bonding material or it may be segmented (18, 20) to facilitate bending the electrode onto a spool. Any hygroscopic material of the electrode may be included in the core to protect it from exposure to atmospheric moisture.

摘要： An acoustic transceiver is implemented for measuring acoustic properties of a gas in a turbine engine combustor. The transceiver housing defines a measurement chamber and has an opening adapted for attachment to a turbine engine combustor wall. The opening permits propagation of acoustic signals between the gas in the turbine engine combustor and gas in the measurement chamber. An acoustic sensor mounted to the housing receives acoustic signals propagating in the measurement chamber, and an acoustic transmitter mounted to the housing creates acoustic signals within the measurement chamber. An acoustic measurement system includes at least two such transceivers attached to a turbine engine combustor wall and connected to a controller.

摘要： An annular fluid distribution device (20) for distributing fluid into a gaseous flow (14), that includes: a first fluid distribution manifold (30) having a first fluid inlet and first fluid outlets (24), wherein the first fluid outlets inject a first fluid into the gaseous flow; and a second fluid distribution manifold (32), having a second fluid inlet and second fluid outlets (26), wherein the second fluid outlets inject a second fluid into the gaseous flow. The second fluid manifold is isolated from the first fluid distribution manifold, and the first fluid outlets and the second fluid outlets are disposed on a common fluid outlet plane (43).

摘要： A component (34A, 34B, 34C) has a core formed of a stack (25, 36) of sheets (20) of material with cutouts (22A) aligned to form passages (38) in the core. An outer casing (29) spans the stack axially (51), brackets at least parts of opposed ends of the stack, and holds the sheets together in axial compression (46). Respective cooperating elements (30, 31) on the casing and the stack may register the casing with respect to the stack. Pins (24) in some sheets may engage holes (23) in adjacent sheets to register the sheets with each other. The casing may be segmented (28A, 28B, 28C). A hoop (66) may be compressed around the segmented casing. A gas turbine fuel injector may be formed of a stack (36) with an inlet element (44) compressed (46) onto the stack by the casing (29).

摘要： Internal components of power generation machines, such as gas or steam turbines, are inspected with a laser profilometer inspection system that is inserted and positioned within the turbine, for example through an inspection port that is in communication with an open inter-row spacing volume between an opposing turbine vane and turbine blade row. Component surface profile scans are performed to determine relative profile heights along a two-dimensional scan line generated by the profilometer. Three-dimensional profile information is obtained by translating the scan line across the surface. Real time profile information is gathered without physical contact, which is helpful for extracting off-line engineering information about component surface conditions, including surface spallation, perforation, and gaps between components. The system is capable of determining blade tip gap between a turbine blade tip and its opposing abradable surface in the turbine casing.
