A combustor component according to at least one embodiment of the present invention includes a cylindrical body which internally includes a combustion chamber, and includes a weld part where a plurality of through holes opening to the combustion chamber are formed, and a housing which is disposed on an outer circumferential side of the cylindrical body to cover a part of the weld part, and defines an acoustic damping space communicating with the combustion chamber via at least one of the through holes. The plurality of through holes in the weld part has a formation density which is higher in a first region of the weld part covered with the housing than in a second region of the weld part positioned outside the housing.

Wall assemblies for a combustor of a gas turbine engine are disclosed. A wall assembly comprises an outer shell made of a metallic material, adjacent first and second inner panels mounted to the outer shell via an insert and a damper disposed between the outer shell and at least one of the first and second inner panels. The first and second inner panels may be spaced apart from the outer shell to define a double-wall configuration with the outer shell. The first and second inner panels may be made of a composite material. The insert may be made from substantially the same or other type of composite material.

A combustor including a combustor lining, a tile including a recess at an end defining a receiving surface, and a tile holder. The tile holder includes an elongate retaining head having a combustor surface configured to face a combustion chamber of a combustor, and a securing portion extending from the head, the securing portion being configured to secure the head to a combustor lining. The retaining head extends laterally with respect to an elongate direction of the retaining head to define a retaining surface laterally adjacent to the securing portion; and the retaining surface cooperates with the receiving surface of the tile to retain the tile against the combustor lining. There is also disclosed a tile holder and a tile.

A combustor may comprise an outer combustor panel and an inner combustor panel radially inward of the outer combustor panel. A bulkhead panel may extend radially between the outer combustor panel and the inner combustor panel. An outer spacer may be located between an outer flange of the bulkhead panel and the outer combustor panel. An inner spacer may be located between an inner flange of the bulkhead panel and the inner combustor panel.

A combustor for a gas turbine engine, the gas turbine engine defining a longitudinal centerline extending in a longitudinal direction, a radial direction extending orthogonally outward from the longitudinal centerline, and a circumferential direction extending concentrically around the longitudinal centerline, the combustor including: a forward liner segment; an aft liner segment disposed downstream from the forward liner segment relative to a direction of flow through the combustor, the forward and aft liner segments at least partially defining a combustion chamber; and an intermediate member disposed at least partially between the forward and aft liner segments and extending in the circumferential direction.

In this method for mounting a combustor component, a component hanging step for attaching a string material to a hanging jig mounted on a combustor component and hanging the combustor component with the string material together with the hanging jig, and a component mounting step for mounting a mounting flange of the combustor component at a combustor mounting position of a gas turbine casing are executed. The hanging jig has a hanging tool having a portion which becomes a suspension point contacted by the string material when the string material is attached and hanging the combustor component. The suspension point is positioned on the distal end side of the center of gravity of the combustor component in the combustor axial line direction when the hanging jig has been mounted to the mounting flange.

A turbofan gas turbine engine configured to reduce hotspots within combustors. The engine includes an axis and a combustor that is circumferentially disposed about the axis. The combustor includes an annular combustor liner that includes a front portion and a rear portion. The annular combustor liner is joined to an annular combustor dome via front portion and defines a chamber and a nozzle is mounted within the annular combustor dome and is configured to inject fuel into a plurality of swirlers. At least one or more dilution openings is circumferentially distributed around the liner such that a region is fluidly connected through the annular combustor liner to the chamber. Each one of the pluralities of dilution openings includes an opening and a radial support wall that is positioned aft of the opening such that the radial support wall extends into the chamber.

The present disclosure provides devices for guiding an element in a combustion chamber wall opening. Between the welds or brazes joining a bushing with a cup and the trajectory of the ring edge, an intermediate space is reserved in an internal annular groove for said welds or brazes to protrude into, so that said welds or brazes lie outside the trajectory of the ring edge.

A combustion chamber of a gas turbine having a peripheral support structure and a heat shield arranged therein. The support structure has a reduced cross-section on the downstream side and a stop element on the upstream side. There is a gap between the heat shield and the stop element to compensate for different strains and tolerances. For reduction of the cooling air consumption, a peripheral sealing groove which is open towards the heat shield and has a sealing element arranged therein is provided in the stop element, which sealing element rests against the heat shield and covers the gap.
