Turbine rotor blade with serpentine cooling

摘要

A turbine rotor blade has a number of serpentine flow cooling circuits to provide cooling to forward and aft sections of the airfoil and to upper span and lower span sections of the airfoil in order to provide specific cooling to directed sections of the airfoil. A common cooling air supply channel extends the entire spanwise length of the airfoil and supplies cooling air to each of the serpentine flow cooling circuits.
