Abstract
A gas turbine engine airfoil includes a tip corner disposed at the juncture of the airfoil tip and trailing edge, and a cooling hole extends therethrough in direct flow communication with an internal cooling passage thereof. A cross-hole extends perpendicularly into the tip corner and into the cooling hole for discharging from the airfoil a portion of cooling air channeled into the cooling hole. The airfoil tip corner is therefore cooled by the air channeled through the cross-hole received from the intersecting cooling hole.
