ABSTRACT:
A turbomachinery airfoil with at least one internal cooling passage is disclosed. The passage has a pair of opposite walls with turbulence promoters, such as ribs or pin arrays, integral therewith. The ribs/pin arrays are angled with respect to the center line of their respective wall and ribs/pin arrays on opposite walls are angled with respect to each other. At least one gap is provided in each rib to provide a flow path for dust which might otherwise collect behind each rib.
