TURBINE AIRFOIL COOLING SYSTEM WITH PLATFORM EDGE COOLING CHANNELS |
摘要 |
A turbine airfoil of a turbine engine having cooling channels positioned on side surface edges of a platform of the airfoil. The platform may include at least one angled side surface that may be aligned with a side surface of a platform of an adjacent turbine blade. The airfoil may include a suction side edge formed from a first surface at an obtuse angle relative to an upper surface of the platform and a second surface at an obtuse angle relative to a bottom surface of the platform. One or more film cooling slots may be positioned in the first surface and may include a diffusion portion. A damper may also be positioned in a groove between the second surface and an adjacent platform. The damper may include cooling slots on a side surface proximate to the second surface of the suction side edge.
