GAS TURBINE ENGINE COMBUSTOR BULKHEAD ASSEMBLY

摘要

A bulkhead assembly for a combustor of a gas turbine engine includes a bulkhead support shell with a multiple of swirler openings. Each of the multiple of swirler openings is surrounded by a first multiple of cooling impingement passages that define an angle α with respect to a hot side of the bulkhead support shell and a second multiple of cooling impingement passages that define an angle &bgr; with respect to the hot side of the bulkhead support shell. The angle α is different than the angle &bgr;.
