An assembly is provided for a turbine engine. A combustor wall of the turbine engine assembly includes a shell and a heat shield. The combustor wall defines a quench aperture through the shell and the heat shield. The heat shield defines an effusion outlet a distance from the quench aperture equal to between about twenty-five times and about seventy-five times a width of the effusion outlet.

Components for gas turbine engines having a hot side surface, a cold side surface, the cold side surface receiving cooling impingement at one or more cold locations, and at least one thermal transfer feature located between the hot side surface and the cold side surface within the component and arranged such that a condenser section of the thermal transfer feature is located proximate at least one of the cold locations and an evaporator section of the thermal transfer feature is located away from the cold location.

A burner of a turbomachine, particularly a gas turbine engine, has at least one burner section having an annular wall surrounding a respective section of a burner interior, the annular wall including: an annular inner surface delimiting the burner interior, and a plurality of dampening cavities for the dampening of thermo-acoustic vibrations in the burner interior, each dampening cavity being connected to the annular inner surface through at least a dampening hole. A method of manufacturing such a burner includes additive manufacturing of the annular wall as an integrally formed component, or additive manufacturing of the upstream burner section, wherein the intermediate burner section and the downstream burner section as integrally formed component.

A combustor wall is provided for a turbine engine. The combustor wall includes a shell and a heat shield that is attacked to the shell. The heat shield includes a rail and a cooling element connected to the rail in a cavity. The cavity extends in a vertical direction between the shell and the heat shield. The cavity fluidly couples a plurality of apertures in the shell with a plurality of apertures in the heat shield.

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.

An annular grommet is provided for a wall assembly of a combustor section of a gas turbine engine. The annular grommet includes a wall that at least partially defines a chamber. A wall assembly within a gas turbine engine includes a liner panel with a hot side and a cold side. The wall assembly also includes an annular grommet with a passage wall and a flange wall transverse to the passage wall. The annular grommet includes a chamber therein. A method of cooling a wall assembly within a gas turbine engine includes injecting air through a chamber in an annular grommet.

A gas turbine with a sequential combustor arrangement as disclosed includes a first combustor with a first burner for admitting a first fuel into a combustor inlet gas during operation and a first combustion chamber for burning the first fuel, a dilution gas admixer for admixing a dilution gas to the first combustor combustion products leaving the first combustion chamber, a second burner for admixing a second fuel and a second combustion chamber. To assure a temperature profile after the dilution gas admixer and to increase the gas turbine's power and efficiency a vane and/or blade of the turbine has a closed loop cooling. The outlet of the closed loop cooling is connected to the dilution gas admixer for admixing the heated cooling gas leaving the vane and/or blade into the first combustor combustion products.

An annular air swirler configured to receive a fuel injector in a central bore. The swirler has one or more annular channels, defined by radially facing channel walls and having an inlet for receiving compressed air and an axially distal outlet. The channel walls converge inwardly towards the outlet and swirl vanes extend between opposing faces of the walls. The swirler turns incoming air to create a vortex at the channel outlet. An annular cooling apparatus associated with the air swirler is arranged axially adjacently downstream of the channel outlet(s), and includes a skirt portion radially spaced from a converging portion of the outermost channel wall defining a converging portion of a bowed coolant channel. A radially outwardly extending wall connects with the outermost channel wall and, with a face of the skirt portion, defines a radially outwardly extending portion of the bowed coolant channel adapted for increased heat exchange.

A combustor for a gas turbine engine includes a support shell with an angled shell interface; a first liner panel mounted to the support shell via a multiple of studs, the first liner panel including a first rail that extends from a cold side of the first liner panel adjacent to the angled shell interface; and a second liner panel mounted to the support shell via a multiple of studs, the second liner panel including a second rail that extends from a cold side of the second liner panel adjacent to said first rail, the second rail adjacent to the angled shell interface.

In accordance with one aspect of the disclosure, a combustor is disclosed. The combustor may include a shell and a liner disposed within the shell. The combustor may further include a grommet at least partially defining a hole communicating through the shell and liner and a cooling channel communicating through the grommet.
