Clocking of downstream turbine airfoils can provide significant thermal and other performance benefits. The benefit from clocking the downstream airfoils is improved by skewing the airfoil wakes in the upstream turbine airfoils so that an increase in the amount of the radial spans of the clocked, downstream airfoils are impacted by the upstream wakes. This is achieved by skewing the upstream wakes using vortexing and restacking of the upstream airfoils so that the upstream wakes impact a mid-span portion of one clocked, downstream airfoil and two outer span portions of an adjacent clocked, downstream airfoil. |
