Wall elements for gas turbine engine combustors
摘要：
A combustor wall element arrangement for a gas turbine engine comprises an upstream wall element (50A) overlapping a downstream wall element (50B) and defining a gap (37) and an outlet (35) therebetween. In use, a coolant flow exits the outlet (35) to provide a coolant film (D) across at least a part of the downstream wall element (50B). The outlet (35) has a smaller dimension, normal to the downstream wall element (50B), than the gap (37) thereby increasing the velocity of the coolant flow across at the downstream wall element (50B). The resultant film coolant flow is effective further across the downstream wall element.
摘要（中）：

用于燃气涡轮发动机的燃烧器壁元件装置包括与下游壁元件（50B）重叠并在其间限定间隙（37）和出口（35）的上游壁元件（50A）。 在使用中，冷却剂流离开出口（35）以在穿过下游壁元件（50B）的至少一部分提供冷却剂膜（D）。 出口（35）比间隙（37）具有与下游壁元件（50B）垂直的较小的尺寸，从而增加在下游壁元件（50B）处的冷却剂流的速度。 所得薄膜冷却剂流动在下游壁元件进一步有效。
