Abstract
The evolution of the spanwise-hole blade cooling technique is described from its employment in the original blade cooling design of the late 1960’s to its current applications in modern industrial combustion turbines. Descriptions of the design, along with analytical and manufacturing advances which have enabled this technique to remain competitive at higher firing temperatures with the relatively complex designs are included. Verification of the spanwise cooling hole designs by means of pyrometer testing is also presented.
