Patent ID: 8313287

Claim:
A turbine blade comprising: an airfoil including an airfoil outer wall extending radially outwardly from a blade root; a blade tip section including a blade tip floor located at an end of said airfoil distal from said root, said blade tip floor including a pressure side and a suction side joined together at chordally spaced apart leading and trailing edges of said airfoil; and a squealer tip extending radially outwardly from said blade tip floor, said squealer tip comprising: a squealer tip rail located adjacent to said suction side and extending from a first location adjacent to said airfoil trailing edge to a second location adjacent to said airfoil leading edge; and a plurality of chordally spaced fence members located between said airfoil leading and trailing edges, each of said fence members extending from said squealer tip rail toward said pressure side, wherein said fence members are angled in a radial direction toward said airfoil leading edge.
