Abstract
An assembly is provided for a turbine engine. This turbine engine assembly includes a combustor wall. The combustor wall includes a shell, a heat shield and an annular body. The annular body extends through the combustor wall and at least partially defines a quench aperture along a centerline through the combustor wall. The shell defines a first cooling aperture radially outwards of the annular body relative to the centerline and is configured to direct air to impinge against a portion of the annular body between the heat shield and the shell.
Claims18
An assembly for a turbine engine, the assembly comprising:
- a combustor wall including a shell, a heat shield and an annular body;
- the annular body extending a first height along a centerline from the heat shield to the shell through the combustor wall and at least partially defining a quench aperture along the centerline through the combustor wall;
- the shell defining a first cooling aperture radially outward of the annular body relative to the centerline and configured to direct air to impinge against a portion of the annular body between the heat shield and the shell;
- and
- a cooling cavity defined between the shell and the heat shield, the cooling cavity having a second height measured at a radial distance from the portion of the annular body, the second height is less than the first height,
- wherein a funnel-shaped portion of the shell extends around the annular body and defines the first cooling aperture, the funnel-shaped portion defined by the first height at the annular body and the second height at the radial distance around the annular body.
An assembly for a turbine engine, the assembly comprising:
- a combustor wall including a shell, a heat shield and an annular body;
- the annular body extending a first height between the shell and the heat shield and defining a quench aperture in the combustor wall;
- and
- a cooling cavity defined between the shell and the heat shield, the cooling cavity having a second height measured at a radial distance from the annular body, the second height is less than the first height,
- wherein a funnel-shaped portion of the shell extends around the annular body and defines a cooling aperture fluidly coupled with the cooling cavity, the funnel-shaped portion defined by the first height at the annular body and the second height at the radial distance around the annular body.
