  • Turbine nozzle having an angled inner band flange
    Patent number: 10830100
    Abstract: A turbine nozzle for a rotary machine including a centerline axis includes an airfoil including a leading edge and a trailing edge. The airfoil defines a throat location proximate the trailing edge. The turbine nozzle also includes an inner band assembly including a platform portion coupled to the airfoil, and a first flange coupled to the platform portion. The first flange is obliquely oriented with respect to the platform portion, and the platform portion and the first flange intersect at a point axially aligned with the throat location.
