Abstract: A hollow air cooled airfoil blade (10) castable with a single pull core and having internal trip strips (28) at the leading edge. Parallel ribs (16, 18) extend from the pressure side (12) of the blade to the suction side (14). A parting line (32) passes through the most forward point (34) of the airfoil, this being located on the suction side of the leading edge (36).
