This paper presents an iterative solution method and calculation examples of the flow distribution, the temperature increase and the heat transfer coefficient of the air-cooled turbine blades in the composite air-cooled turbine blade. The effects of the rotation effect on the flow and heat transfer of the cold air are also discussed. And successfully applied to the design of air-cooled blades for high-performance propulsion system. It can also be used for gas turbine blades retrofitting and mold bottom analysis, checking
