摘要:
A combustor wall is provided for a turbine engine. The combustor wall includes a shell, a heat shield and a cooling element. The shell defined a first set of apertures. The heat shield defines a second set of apertures. The cooling element extends between the shell and the heat shield within a tapered cooling cavity defined between the shell and the heat shield. The tapered cavity is fluidly coupled with the first and the second sets of apertures. The cooling element is thermally coupled to one of the shell and the heat shield.

An assembly is provided for a turbine engine. This turbine engine assembly includes a combustor wall, which includes a shell, a heat shield and an annular body. The body at least partially defines a first aperture through the shell and the heat shield. The body also defines one or more second apertures through which air is directed into the first aperture and provides non-uniform cooling to the body.

A multi-walled structure is provided for a turbine engine. This structure includes a shell with a textured first surface, and a heat shield with a second surface. The heat shield is attached to the shell. The first and the second surfaces vertically define a cooling cavity between the shell and the heat shield. The cooling cavity fluidly couples a plurality of cooling apertures defined in the shell with a plurality of cooling apertures defined in the heat shield.

An assembly is provided for a turbine engine. This turbine engine assembly includes a body, a shell and a heat shield panel. The panel is attached to the shell with a tapered cooling cavity between the shell and the panel. The panel defines a cooling aperture configured to direct air out of the cooling cavity to impinge against the body.

A fuel injector (68) guide is provided for a turbine engine combustor 954). The fuel injector guide (68) includes a tubular base (86), an annular flange (88), a plurality of ribs (90, 92) and a flow turbulator (94). The base (86) extends along an axis (96) between first and second ends (98, 100). The flange (88) extends radially out from the base (86) at the second end (100). The ribs (90, 92) are disposed around the base (86) and extend axially out from the flange (88) towards the first end (98). The flow turbulator (94) is disposed between an adjacent pair of the ribs (90, 92).

A nozzle guide (105; 205; 300; 305; 405) is provided for a combustor (110) of a gas turbine engine (100). The nozzle guide includes an annular structure (130; 230; 330; 430) including a plurality of cooling holes (135; 235; 335; 435), a guide plate (140; 240; 340; 440) including a plurality of openings (145; 245; 345; 445) on an outer periphery of the guide plate, and a plurality of cooling passages (247; 334; 426) within the annular structure to provide air flow from the plurality of cooling holes to the plurality of openings.

An assembly for a turbine engine 20 is provided that includes a combustor wall 76, 78, which includes an aperture body 100 between a shell 86, 88 and a heat shield 82, 84. The aperture body 100 at least partially forms a cavity 132 and an aperture 72, 74 that extends through the combustor wall 76, 78. An inlet passage 134 extends in the combustor wall 76, 78 to the cavity 132. An outlet passage 136 extends in the combustor wall 76, 78 from the cavity 132 to the aperture 72, 74.
摘要:
A combustor liner is arcuate in shape and defines an axis and a circumferential direction. The combustor liner includes a first row of dilution openings and a second row of dilution openings. The first row runs in the circumferential direction. The second row runs parallel to the first row and is axially spaced from the first row. Each dilution opening of the second row overlaps in an axial direction a portion of each of two adjacent dilution openings of the first row.
