摘要:
A combustor heat shield has a body with heat exchange promoting protuberances extending from a back face thereof. The density of protuberances is less in hot spot regions than in other heat shield regions which require less cooling.
摘要:
Impingement hole patterns are provided in a combustor dome panel to provide efficient cooling of a combustor dome heat shield. The impingement holes are substantially aligned or located above partial height protuberances provided on the back face of the heat shield.

摘要:
A gas turbine engine combustor having a dome heat shield includes a cooling scheme having a plurality of impingement cooling holes extending through the combustor and a plurality of adjacent ejector holes for directing cooling air past the heat shield lips of the dome heat shields. The impingement and ejector holes are preferably staggered to reduce interaction therebetween.
