Zusammenfassung:	An engine component (80) for a gas turbine engine (10) includes a film-cooled substrate (82) having a hot surface (84) facing hot combustion gas and a cooling surface (86) facing a cooling fluid flow. The substrate (82) includes one or more film holes (90, 130, 160) that have a metering section (98, 138, 168) defining a metering diameter and a diffusing section (100, 140, 170) that defines a hooded length. 种用于燃气涡轮发动机(10)的发动机构件(80)包括膜冷却的基底(82)，该基底(82)具有面对热燃烧气体的热表面(84)和面对冷却流体流的冷却表面(86)。该基底(82)包括个或更多个膜孔(90、130、160)，膜孔具有限定计量直径的计量区段(98、138、168)和限定罩盖长度的扩散区段(100、140、170)。
