Abstract
A vascular wall of a combustor that may be for a gas turbine engine includes a first face defining at least in-part a combustion chamber, a second face defining at least in-part a cooling air plenum, and a vascular lattice structure located between the first and second faces for distributing cooling air from the plenum and to the chamber. The vascular lattice structure may be configured to enhance cooling air flow where needed whiling providing structural support. The orientation of the vascular lattice structure may further contribute toward acoustic dampening.
Claims14
A combustor wall comprising:
- a hot side panel comprising a first face, the first face defining at least in-part a combustion chamber;
- a cold side panel comprising a second face, the second face defining at least in-part a cooling air plenum;
- and a vascular lattice structure located between the first and second faces for distributing cooling air from the cooling air plenum and to the combustion chamber;
- the cold side panel spaced from the vascular lattice structure so as to define an annular cooling cavity therebetween.
A combustor of a gas turbine engine comprising:
- a hot side panel defining at least in-part a combustion chamber;
- a cold side panel spaced from the hot side panel and defining a cooling air plenum;
- and a vascular lattice structure located in an annular cooling cavity defined between the hot and cold side panels;
- wherein a gap extends between and separates the cold side panel and the vascular lattice structure to define a portion of the annular cooling cavity that accepts air from the cooling air plenum.
