A bulkhead panel 28 for use in a combustion chamber of a gas turbine engine comprises a first side 34 and a second side 32, a plurality of panel holes 60,62 extending from the first side 34 to the second side 32 through which cooling air flows, and a circumferential inner rail 54 on said first side 34 dividing said first side 34 into a first cavity region 56 having a plurality of the panel holes 60 and a second cavity region 58 having a plurality of the panel holes 62. Each of the panel holes 60,62 has an exit nozzle which is angled so as to create a swirling flow of cooling air over the second side 32 of the panel 28.
