Abstract
An assembly is provided for a turbine engine. This turbine engine assembly includes a combustor wall, which includes a shell and a heat shield. The heat shield includes a base and a plurality of panel rails. The panel rails are connected to the base and extend vertically to the shell. The panel rails include first and second rails. A vertical height of the first rail at a first location is less than a vertical height of the second rail at a second location.
Claims15
An assembly for a turbine engine, the assembly comprising:
- a combustor wall including a shell and a heat shield, the heat shield including a base and a plurality of panel rails connected to the base and extending vertically to the shell, the plurality of panel rails including first and second rails;
- wherein a vertical height of the first rail at a first location is less than a vertical height of the second rail at a second location;
- and
- wherein the vertical height of the first rail varies as the first rail extends longitudinally along the base.
An assembly for a turbine engine, the assembly comprising:
- a combustor wall including a shell and a heat shield, the heat shield including a base and a plurality of panel rails connected to the base and extending vertically to the shell, the plurality of panel rails including first and second rails:
- a mechanical attachment attaching the base to the shell;
- and
- a plurality of protrusions arranged around the mechanical attachment and connected to the base;
- wherein a vertical height of the first rail at a first location is less than a vertical height of the second rail at a second location, and
- wherein a vertical height of one of the plurality of protrusions is equal to the vertical height of the first rail at the first location.
An assembly for a turbine engine, the assembly comprising:
- a combustor wall including a shell and a heat shield, the heat shield including a base and a plurality of panel rails connected to the base and extending vertically to the shell, the plurality of panel rails including first and second rails;
- wherein a vertical height of the first rail at a first location is less than a vertical height of the second rail at a second location;
- and
- wherein the plurality of panel rails includes a third rail and a fourth rail, and the first rail and the second rail extend between the third rail and the fourth rail.
A combustor wall for a turbine engine, the combustor wall comprising:
- a combustor shell;
- and
- a combustor heat shield panel including a plurality of panel rails that extend vertically to the combustor shell, the plurality of panel rails including an intermediate rail arranged between first and second end rails,
- wherein a mean vertical height of the intermediate rail is less than a mean vertical height of the first end rail;
- and
- wherein the mean vertical height of the first end rail is less than a mean vertical height of the second end rail.
