Abstract
An integrated airfoil and platform cooling system () for a turbine rotor blade () includes an inlet () located at the root () for receiving a supply of a coolant (K), and at least one cooling leg () fluidly connected to the inlet () and configured for conducting the coolant (K) in a radially outboard direction. The cooling leg () is defined at least partially by a span-wise extending internal cavity () within a blade airfoil (). An entrance of the cooling leg () comprises a flow passage () that extends radially outboard and laterally into a blade platform (), so as to direct a radially outboard flowing coolant (K) to impinge on an inner side () of a radially outer surface () of the blade platform (), before leading the coolant (K) into the cooling leg ().
