摘要:
Die vorliegende Erfindung betrifft einen Dichtungskörper (1) zum Abdichten eines äußeren Bauteils (2) gegenüber einem inneren Bauteil (3), insbesondere bei einer Brennkammer einer Gasturbine. Das äußere Bauteil (2) weist eine Durchgangsöffnung (4) auf, durch die das innere Bauteil (3) aus dem äußeren Bauteil (2) herausragt. Der Dichtungskörper (1) ist im Einbauzustand im Bereich der Durchgangsöffnung (4) angeordnet, umfasst das innere Bauteil (3) umfangsmäßig geschlossen, liegt mit einer inneren Dichtzone (7) an einer Außendichtfläche (6) des inneren Bauteils (3) umfangsmäßig geschlossen an und liegt mit einer äußeren Dichtzone (8) an einer Innendichtfläche (5) des äußeren Bauteils (2) umfangsmäßig geschlossen an. Der Dichtungskörper (1) ist aus wenigstens einem in Umfangsrichtung geschlossenen bandförmigen Metallblech durch Umformung hergestellt. An einem Profil des Dichtungskörpers (1) sind entlang des gesamten Umfangs die innere Dichtzone (7) und die äußere Dichtzone (8) ausgebildet.
摘要:
A liner cap assembly (30) is disclosed for use in a gas turbine engine combustor (12). The assembly includes an outer ring (52) that extends along an axis. Multiple struts (44) are circumferentially arranged about an inner diameter of the outer ring (52) and extend radially inwardly therefrom. A plate (46) is supported by and axially aligned with the struts (44). The plate (46) includes multiple circumferential openings (66) that support a collar (38) and a premix tube (42) at each of the openings (66). The plate (46) is arranged between leading and trailing edges (80,82) of the struts (44) to provide a stiffened liner cap assembly (30) that is robust and resistant to the vibrations typically found in dry low NOx systems.

A transfer tube (34) for use in a late lean injection system of a combustor, wherein the combustor includes an inner radial wall (24), which defines a primary combustion chamber downstream of a primary fuel nozzle, and an outer radial wall (26), which surrounds the inner radial wall forming a flow annulus (27) therebetween, the outer radial wall including a late lean nozzle (33) and a transfer tube (34) including flow directing structure that defines a fluid passageway. At a first end (45), the flow directing structure may include an inlet and attachment means (41) that attach the transfer tube (34) to the late lean nozzle (33). The flow directing structure may have a configuration such that the fluid passageway spans the flow annulus (27) and positions the outlet at a desirable injection point in the inner radial wall (24).

A vane assembly has an outer support ring (96), an inner support ring (92), an outer liner ring (98), an inner liner ring (94), and a circumferential array of vanes (70). Each vane (70) has a shell (180) extending from an inboard end (182) to an outboard end (184) and at least partially through an associated aperture (198) in the inner liner ring (94) and an associated aperture (199) in the outer liner ring (98). There is at least one of: an outer compliant member (212) compliantly radially positioning the vane (70); and an inner compliant member (210) compliantly radially positioning the vane (70).

A flexible annular seal (10) for insertion between concentrically assembled turbine combustor components includes an annular inner seal portion (12) having a first solid annular edge (16) and first plurality of spring fingers (14) extending axially from the first solid annular edge; and an annular outer seal portion (18) having a second solid annular edge (22) and a second plurality of spring fingers (20) extending axially from the second solid edge and overlying the first plurality of spring fingers such that the inner and outer seal portions are substantially fully engaged along an entire length dimension of the flexible annular seal. The second plurality of spring fingers (20) are circumferentially offset from the first plurality of spring fingers, and free ends of the first plurality of spring fingers (14) are bent around and over free ends of the second plurality of spring fingers (20).
摘要:
A mount device (100) and mounting assembly (102) for a turbine system (10) are disclosed. The mounting assembly (102) includes a transition duct (50) extending between a fuel nozzle and a turbine section. The transition duct (50) has an inlet (52), an outlet (54), and a passage (56) extending between the inlet (52) and the outlet (54) and defining a longitudinal axis (90), a radial axis (94), and a tangential axis (92). The outlet (54) of the transition duct (50) is offset from the inlet (52) along the longitudinal axis (90) and the tangential axis (92). The mounting assembly (102) further includes a mount device (100) connecting the transition duct (50) to the turbine section. The mount device (100) is configured to allow movement of the outlet (54) about at least two axes.

A system includes a gas turbine combustor (16), which includes a combustion liner (42) disposed about a combustion region, a flow sleeve (44) disposed about the combustion liner (42), an air passage (46) between the combustion liner (42) and the flow sleeve (44), and an aerodynamic mounting assembly (66) disposed in the air passage (46). The aerodynamic mounting assembly (66) is configured to retain the combustion liner (42) within the flow sleeve (44). The aerodynamic mounting assembly (66) includes a flow sleeve mount (68) coupled to the flow sleeve (44) and a liner stop (70) coupled to the combustion liner (42). The flow sleeve mount (68) includes a first portion of an aerodynamic shape and the liner stop (70) includes a second portion of the aerodynamic shape, which is configured to direct an airflow (82) into a wake region (67) downstream of the aerodynamic mounting assembly (66). The flow sleeve mount (68) and the liner stop (70) couple with one another to define the aerodynamic shape.
