A variable penetration dilution jet array for a single can and scroll assembly includes a plurality of differentially sized dilution openings around the circumference of the combustor can. The alternating smaller and larger openings provide for circumferential and radial mixing uniformity with the smaller openings giving shallow penetration and the larger openings enabling deep core penetration. The larger openings provide dilution air to the hot gas flow core without the need for an increase in combustor pressure drop. The smaller openings provide a fi...
We claim: 1. A combustor assembly comprising: a combustor can used with a scroll; and a variable penetration dilution jet array positioned in an aft portion of said combustor can there through, said variable penetration dilution jet array providing a dilution air flow such that a pattern factor at an exit plane of said combustor can is reduced and provides a film cooling flow to said scroll. 2. The combustor assembly of claim 1, wherein said variable penetration dilution jet array is positioned in one axial plane of said aft portion. 3. The combust...
