Abstract
A combustor includes an outer liner having a first row and a second row of circumferentially distributed air admission holes penetrating therethrough. The combustor further includes an inner liner circumscribed by the outer liner and having a first row and a second row of circumferentially distributed air admission holes penetrating therethrough. The combustor further includes a plurality of fuel injectors extending into the combustion chamber and configured to deliver an air-fuel mixture to the combustion chamber. Each of the plurality of fuel injectors are associated with two air admission holes in the first row of the outer liner, two air admission holes in the first row of the inner liner, four air admission holes in the second row of the outer liner, and two air admission holes of the second row of the inner liner.
