Abstract
A combustor liner for a gas turbine engine, the combustor liner defining a combustion chamber, includes a curved body and a cooling ring. The curved body includes a closed forward end, an open aft end opposite the forward end, an inner wall, and an outer wall radially outward from the inner wall, the outer wall defining an outer liner wall of the combustor liner. The cooling ring includes a fin that has a space filling curve that is modified such that an outer wall of the cooling ring matches a shape of the inner wall of the curved body. An inner wall of the cooling ring defines an inner liner wall of the combustor liner.
Claims18
A combustor liner for a gas turbine engine, the combustor liner defining a combustion chamber and comprising:
- a curved body comprising:
- a closed forward end;
- an open aft end opposite the forward end;
- an inner wall, and
- an outer wall radially outward from the inner wall, the outer wall defining an outer liner wall of the combustor liner;
- and
- a cooling ring comprising a fin that has a space filling curve that is modified such that an outer wall of the cooling ring matches a shape of the inner wall of the curved body, wherein an inner wall of the cooling ring defines an inner liner wall of the combustor liner and wherein the space filling curve is a Hilbert curve or a Peano curve.
A combustor liner for a gas turbine engine, the combustor liner defining a combustion chamber, the combustor liner comprising:
- a body defining a combustion chamber, the body comprising:
- an inner wall;
- and
- an outer wall radially outward from the inner wall;
- and
- a cooling ring comprising:
- a fin, wherein the fin has a Hilbert curve or a Peano curve;
- an inlet formed by the fin at an upstream end of the cooling ring;
- an outlet formed by the fin at a downstream end of the cooling ring opposite the inlet;
- a channel formed by the fin and extending from the inlet of the cooling ring to the outlet of the cooling ring;
- an outer wall extending from the inlet to the outlet;
- and
- an inner wall radially inward from the outer wall and extending from the inlet to the outlet;
- wherein the outer wall of the cooling ring matches a shape of the inner wall of the body;
- and
- wherein the inner wall of the cooling ring defines an inner liner wall of the combustor liner.
