A turbine airfoil (14) includes first and second sidewalls (20,22) joined together at leading and trailing edges (24,26), and spaced apart to define first and second cavities (34,36) separated by a septum (38) therebetween. An aft bridge (40) extends along the first cavity and includes a row of outlet holes (44) therein. The septum includes a row of inlet holes (42), and turbulators (46) are disposed in rows inside the first cavity, and extend from the first sidewall toward the second sidewall. The turbulators are aligned with the inlet holes for multiple impingement cooling thereof. <IMAGE> |
