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.

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.
摘要翻译： 燃烧器隔热罩具有从其背面延伸的具有热交换促进突起的主体。 热点区域的突起密度比其他需要较少冷却的热屏蔽区域要小。

摘要： A combustor liner for a gas turbine engine including first and second annular liner portions engaged to one another with an interference fit. The first liner portion includes at least one anti-rotation feature extending therefrom and engaging the second liner portion and having a threaded hole defined therethrough at least substantially perpendicularly to an adjacent radially extending surface of the second liner portion for threadingly receiving a pushing tool for pushing against that surface.
