摘要：
A turbine rotor blade with a blade tip cooling circuit that is formed by bonding a blade tip to a top side of an airfoil. The blade tip includes a first series of ribs formed on a bottom side that defines a first layer of tip cooling holes. The top side of the airfoil includes a second series of ribs that define a second layer of cooling holes. The first and second series of ribs are formed before the blade tip is bonded to the airfoil to enclose the two layers of tip cooling holes that open onto the walls of the blade below the tip edge.
