Abstract
The flow of cooling fluid through a core tie hole formed between a pair of internal cooling passageways of an airfoil component is reduced by providing a restriction that meters coolant flow through the inlet passage of one of the passageways so that the pressures in the two passageways are equalized, thereby minimizing the flow of cooling fluid through the hole. The restriction can be a metering plate disposed at the entrance of the inlet passage or a restriction integrally formed in the inlet passage.
