Abstract
Combustor panels of gas turbine engines and gas turbine engines are described. The combustor panels include a hot side configured to be exposed to combustion within a gas turbine engine, a cold side opposite the hot side of the combustor panel, the cold side configured to receive cooling flow thereon, and a peak-valley gridded pattern formed on the cold side, the peak-valley gridded pattern comprising a plurality of recessed cells arranged in a grid pattern, with each recessed cell having a peak, angled sidewalls, and an effusion hole located at a bottom of the angled sidewalls.
Claims18
A combustor panel of a gas turbine engine comprising:
- a hot side configured to be exposed to combustion within the gas turbine engine;
- a cold side opposite the hot side of the combustor panel, the cold side configured to receive cooling flow thereon, wherein the cold side defines a reference planar surface;
- and
- a peak-valley gridded pattern formed on the cold side, the peak-valley gridded pattern comprising a plurality of recessed cells arranged in a grid pattern, with each recessed cell having angled sidewalls with peaks disposed distally to the angled sidewalls and opposite the hot side and a respective effusion hole located at a bottom of the angled sidewalls and the plurality of recessed cells are recessed relative to the reference planar surface and the peaks contact the reference planar surface or are recessed relative to the reference planar surface, and
- wherein the angled sidewalls of at least one cell of the plurality of recessed cells have linear slopes.
A gas turbine engine comprising:
- a combustor section having a combustor shell and one or more combustor panels mounted to the combustor shell,
- wherein at least one combustor panel of the one or more combustor panels comprises:
- a hot side configured to be exposed to combustion within the combustor section;
- a cold side opposite the hot side of the at least one combustor panel, the cold side facing the combustor shell and configured to receive cooling flow thereon, wherein the cold side defines a reference planar surface;
- and
- a peak-valley gridded pattern formed on the cold side, the peak-valley gridded pattern comprising a plurality of recessed cells arranged in a grid pattern, with each recessed cell having angled sidewalls with peaks disposed distally to the angled sidewalls and opposite the hot side and a respective effusion hole located at a bottom of the angled sidewalls and the plurality of recessed cells are recessed relative to the reference planar surface and the peaks contact the reference planar surface or are recessed relative to the reference planar surface, and
- wherein the angled sidewalls of at least one cell of the plurality of recessed cells have linear slopes.
