Combustor cooling hole pattern
First Claim
1. A combustor liner assembly comprising:
- a liner defining an opening;
a first group of cooling holes formed in said liner beginning upstream of said opening and continuing downstream of a leading edge of said opening; and
a second group of cooling holes disposed outside of said first group of cooling holes, said second group of cooling holes spaced apart a greater distance than said first group of cooling holes.

Abstract
A combustor assembly includes an inner and outer liner defining a combustion chamber. The inner and outer liners include a plurality of cooling holes spaced a specified distance apart. The cooling holes include first, second and third groups. The first group of cooling holes is the most densely spaced, followed by the second group and then the third group. The first group of cooling holes begin upstream of a leading edge of a large opening and terminates downstream of the leading edge. The increased density of cooling holes adjacent the large openings provide increased cooling airflow in areas where cooling may be affected by local disturbances in cooling airflow.
