Abstract
Vane assemblies and gas turbine engines having vane assemblies are described. The vane assemblies include a vane having outer and inner diameter ends and at least a leading-edge cavity therein. A direction of flow through the leading-edge cavity is from the outer diameter end toward the inner diameter end. An inner diameter platform is arranged at the inner diameter end of the vane and includes an inner diameter flow path having an exit at an aft side of the inner diameter platform. The inner diameter platform includes an inner diameter flow aperture fluidly coupling the leading-edge cavity and the inner diameter flow path. A baffle is installed within the leading-edge cavity and arranged to reduce a cross-sectional area in the direction of flow of the leading-edge cavity such that the leading-edge cavity has a larger cross-sectional area proximate the outer diameter end than at the inner diameter end.
