PROBLEM TO BE SOLVED: To provide an airfoil of a turbine blade defined by a pressure side outer wall and a suction side outer wall.SOLUTION: A pressure side outer wall 26 and a suction side outer wall 27 connect along a leading edge 28 and a trailing edge 29 and form a radially extending chamber for receiving a coolant flow. A rib configuration may include: a leading edge transverse rib connecting to the pressure side outer wall and the suction side outer wall and partitioning a leading edge passage from the radially extending chamber; and a first center transverse rib connecting to the pressure side outer wall and the suction side outer wall and partitioning an intermediate passage from the radially extending chamber directly aft of the leading edge passage. The intermediate passage is defined by the pressure side outer wall, the suction side outer wall, the leading edge transverse rib and the first center transverse rib, and thus spans an airfoil between its outer walls.SELECTED DRAWING: Figure 4
