Airfoil

A blading member for a turboengine, the blading member comprising:

• a foot;
• and
• at least one airfoil, the airfoil extending along a spanwidth direction from a base to a tip, the base being connected to the foot of the blading member, wherein the airfoil includes:
• an airfoil aerodynamic body, the aerodynamic body having a suction side surface, a pressure side surface, a leading edge, a trailing edge and a tip, said tip of the aerodynamic body having a tip cross section and a cross-sectional contour circumscribing the tip cross section;
• a rim disposed at the tip of the aerodynamic body and extending to the tip of the airfoil and following said cross-sectional contour on the pressure side, the suction side, and extending over the leading edge of the airfoil, the rim delimiting a tip cavity which is open at the tip of the airfoil, wherein the rim is open at the trailing edge of the airfoil such that the tip cavity is open at the trailing edge of the airfoil;
• and
• at least one fluid duct having a discharge orifice which opens out onto a bottom of the tip cavity through said discharge orifice the at least one fluid duct being arranged and configured as a film cooling duct.
