Abstract: An airfoil for a turbine engine comprises: - an outer wall defining a pressure sidewall (98) and a suction sidewall (100), extending chord-wise from a leading edge (102) to a trailing edge (104) and span-wise from a root to a tip (80); - a tip shelf (126) disposed in the pressure sidewall and at least partially defined by the outer wall; and - at least one film hole (132) extending into the tip shelf and having an inlet and an outlet connected by a passage fluidly coupling the inlet to the outlet, with the outlet having an expansion section (136).
