A turbine airfoil (12) includes opposite pressure and suction sides (18,20) extending in span from a flowpath surface (28). The flowpath surface (28) has chordally opposite forward and aft edges (30,32) and laterally opposite first and second endfaces (34,36) corresponding with the airfoil pressure and suction sides (18,20). The flowpath surface (28) joins the first endface (34) at the forward edge (30) in a forward bullnose (42) and joins the second endface (36) at the aft edge (32) in an aft bullnose (44), with the bullnoses (42,44) varying in radius from the opposite edges (30,32). |
