摘要:
Turbine blades with non-axisymmetric forward features are provided. A turbine blade may include a platform and an airfoil extending radially outward from the platform and configured to extend into a fluid flowpath. The airfoil separates an upstream portion of the fluid flowpath from a downstream portion of the fluid flowpath. A sealing member extends axially from the platform toward a stationary nozzle adjacent the platform and separates the fluid flowpath from a wheel space. The platform may have a forward face between the sealing member and the airfoil and, optionally, a forward axial face between the forward face and the airfoil. The forward face or forward axial face may face the upstream portion of the fluid flowpath and may have a profile that is non-axisymmetric with respect to its centerline axis.
