Abstract: Embodiments of hot streak alignment for gas turbine durability include structures and methods to align hot streaks with the leading edges of aligned first stage nozzle vanes in order to improve mixing of the hot streaks with cooling air at a stator nozzle of a first stage turbine and reduce usage of cooling air at first stage non-aligned stator nozzle vanes disposed adjacent to the aligned stator vanes.

CPC classification number: F01D5/186 , F01D5/187 , F01D9/02 , F05D2240/303 , F05D2260/202 , Y02T50/673 , Y02T50/676
Abstract: A durable nozzle vane includes a leading edge where hot combustion gas impinges on the vane, a pressure side extending from the leading edge to a trailing edge and a suction side extending from the leading edge to the trailing edge, a blunt region along the suction side between the leading edge and a high curvature region, the blunt region having small curvature in the length between the leading edge and the high curvature region allowing for at least two rows of cooling apertures.
Abstract translation: 耐用的喷嘴叶片包括其中热燃烧气体撞击在叶片上的前缘，从前缘延伸到后缘的压力侧和从前缘延伸到后缘的吸力侧，沿着吸力侧的钝区 在前缘和高曲率区域之间，平坦区域在前缘和高曲率区域之间的长度上具有小曲率，允许至少两排冷却孔。
