ABSTRACT:
A turbine airfoil for use in a gas turbine engine, the airfoil formed from a support spar with a leading edge rib having a row of impingement cooling holes, the support spar having an array of modules formed on the pressure side and the suction side of the spar, and a number of cavities separated by ribs extending across the walls of the support spar. Each module is rectangular in shape and includes an impingement compartment and a diffusion compartment separated by a rib with crossover holes to connect the two compartments. Impingement holes connect the impingement compartment to a first cavity, and spent air cooling holes connect the diffusion compartment to a second cavity located downstream from the first cavity.
