TLDR
In this paper, the annulus profile of the hot gas path is defined in conjunction with the airfoil profile and the profile of inner and outer walls by the Cartesian coordinate values given in Tables I and II, respectively.Abstract:
A first-stage nozzle vane includes an airfoil having a profile according to Table I. The annulus profile of the hot gas path is defined in conjunction with the airfoil profile and the profile of the inner and outer walls by the Cartesian coordinate values given in Tables I and II, respectively. The airfoil is a three-dimensional bowed design, both in the airfoil body and in the trailing edge. The airfoil is steam and air-cooled by flowing cooling mediums through cavities extending in the vane between inner and outer walls.read more
