Abstract

A turbine blade includes a root, tip, and airfoil. The turbine blade defines a serpentine interior passage having first through third legs, and first and second junctions. The first leg receives pressurized gas from a supply channel of the root. The first leg extends radially and the first junction connects it to the second leg proximate the tip. The second leg extends radially between the first and second junctions. The second junction connects the second and third legs. The third leg extends radially toward the tip. The tip defines cooling apertures open through a pressure side thereof. The cooling apertures include a forward aperture with a forward end opening into the first junction and an aftward end opening through the pressure side surface of the tip at a location that is radially outward of the third leg and axially aftward of at least a portion of the third leg.
