<p>A turbine blade (24) includes an airfoil portion including a suction side (44) having a suction side contour, a pressure side (45) having a pressure side contour, a leading edge (47), a trailing edge (48) and a tip portion (50), and a squeeler pocket (60) formed in the tip portion (50). The squeeler pocket (60) includes a first side wall (66) and a second side wall (67). The first side wall (66) includes a first internal surface (69) having a first substantially continuous curvilinear profile and the second side wall (67) includes a second internal surface (72) having a second substantially continuous curvilinear profile. A bleed passage (84) extends from the squeeler pocket (60) towards the trailing edge (48). The first and second side walls (66,67) are configured to deliver a substantially unobstructed fluid flow from the squeeler pocket (60) to the bleed passage (84) and limit the fluid flow spillage onto one of the pressure side (42) and the suction side (44).</p> |
