Abstract
A rotor blade such as a turbine rotor blade for a jet engine. The airfoil blade portion of the rotor blade has a plurality of longitudinally extending coolant passageways preferably interconnected to define a serpentine coolant circuit. Each passageway has a wedge shape including a base and an opposing tapered tip. For passageways channeling coolant from the blade root to the blade tip, the bases are positioned proximate the pressure side of the airfoil blade and the tapered tip is positioned proximate the suction side of the airfoil blade to take advantage of the Coriolis force acting on the coolant in the passageway of the rotating blade to improve overall heat transfer effectiveness.
