TURBINE AIRFOIL INCLUDING TIP FILLET

摘要

PROBLEM TO BE SOLVED: To provide a turbine airfoil including a tip fillet.SOLUTION: A turbine blade can include a root configured to connect to a turbine and supporting an airfoil configured to extend into a flowpath of the turbine. The airfoil can include a tip disposed substantially opposite the root, and a first tip fillet disposed proximately to the tip, and the first tip fillet can extend substantially perpendicularly to a local flow direction at points along a surface of the turbine blade over the extremity of the first tip fillet. The tip fillet can enhance performance of the turbine by beneficially altering a flow through a stage in which the blade is included.
