摘要：
A cooled airfoil (38) includes an impingement rib (54) having a multiple of openings (58) which supply a cooling airflow from a cooling circuit flow path (26) toward an airfoil leading edge (36). The multiple of openings (58) are offset in the impingement rib (54) opposite an outer airfoil wall (40S) which includes gill holes (62). Offsetting the multiple of openings (58) opposite an outer airfoil wall (40S) which includes the gill holes (62) focuses the cooling airflow across turbulators (64) to increase the cooling airflow dwell time to increase the thermal transfer therefrom in higher temperature airfoil areas.
