Abstract
A combustor includes a skeleton mesh structure having a plurality of structural elements configured to mesh together to form the skeleton mesh structure, each of the plurality of structural elements including a frame and, a plurality of louvers connected to the frame. The combustor also includes an inner liner mounted to the skeleton mesh structure to define a combustion chamber. The inner liner includes a plurality of inner planks mounted to the skeleton mesh structure, each of the plurality of inner planks being mounted to a corresponding one of the plurality of structural elements.
Claims18
A combustor comprising:
- a skeleton mesh structure comprising a plurality of structural elements configured to mesh together to form the skeleton mesh structure, each of the plurality of structural elements comprising a frame and a plurality of louvers connected to the frame;
- and
- an inner liner mounted to the skeleton mesh structure to define a combustion chamber, the inner liner comprising a plurality of inner planks mounted to the skeleton mesh structure, each of the plurality of inner planks being mounted to the frame of a corresponding one of the plurality of structural elements, the plurality of inner planks being exposable to hot flames within the combustion chamber, each of the plurality of inner planks comprises a plurality of holes,
- wherein two successive louvers in the plurality of louvers are configured such that a first distance L1 between bottoms of the two successive louvers in the plurality of louvers is less than or equal to a second distance L2 between tops of the two successive louvers in the plurality of louvers such that the two successive louvers are spaced apart by a gap to define an opening to allow airflow to pass therethrough, and the plurality of holes of each of the plurality of inner planks are oriented such that a first portion of airflow exiting through the opening enters through at least one of the plurality of holes, and a second portion of airflow exiting through the opening propagates along a surface of each of the plurality of inner planks in a space between the bottoms of the two successive louvers and the surface of each of the plurality of inner planks.
A turbine engine comprising:
- a combustor comprising:
- (a) a skeleton mesh structure comprising a plurality of structural elements configured to mesh together to form the skeleton mesh structure, each of the plurality of structural elements comprising a frame and a plurality of louvers connected to the frame;
- and
- (b) an inner liner mounted to the skeleton mesh structure to define a combustion chamber, the inner liner comprising a plurality of inner planks mounted to the skeleton mesh structure, each of the plurality of inner planks being mounted to the frame of a corresponding one of the plurality of structural elements, the plurality of inner planks being exposable to hot flames within the combustion chamber,
- wherein two successive louvers in the plurality of louvers are configured such that a first distance L1 between bottoms of the two successive louvers in the plurality of louvers is less than or equal to a second distance L2 between tops of the two successive louvers in the plurality of louvers such that the two successive louvers are spaced apart by a gap to define an opening to allow airflow to pass therethrough, and a plurality of holes are defined through each of the plurality of inner planks and are oriented such that a first portion of airflow exiting through the opening enters through at least one of the plurality of holes, and a second portion of airflow exiting through the opening propagates along a surface of each of the plurality of inner planks in a space between the bottoms of the two successive louvers and the surface of each of the plurality of inner planks.
