ABSTRACT:
Undersized cooling holes for air cooling a gas turbine component or the like, are formed at low cost, and are later enlarged to increase the flow rate of cooling air therethrough by blowing a mixture of abrasive grit through the holes to enlarge them. Air without the grit is thereafter passed through the holes and the resulting increased flow rate is measured to see if it is at a satisfactory level. If it is not, the process is repeated until the desired accurate flow rate is achieved.
