摘要: A turbine nozzle includes a row of vanes extending radially in span between inner and outer bands. The vanes include opposite pressure and suction sidewalls and opposite leading and trailing edges. Each vane includes an inner pattern of inner cooling holes and an outer pattern of outer cooling holes distributed along the leading edge. The inner and outer holes diverge toward the corresponding inner and outer bands to preferentially discharge cooling air.
摘要翻译: 涡轮喷嘴包括在内部和外部带之间沿跨度径向延伸的一排叶片。 叶片包括相对的压力和吸力侧壁以及相对的前缘和后缘。 每个叶片包括内部冷却孔的内部图案和沿着前缘分布的外部冷却孔的外部图案。 内孔和外孔朝向相应的内外带发散,优先排出冷却空气。
