A method based on geometric factors of the coolant passage was evolved for the rapid selection and evaluation of coolant passage configurations for air-cooled turbine rotor blades. The more promising coolant passage configurations, as selected by the simple blade evaluation criteria, are then analyzed by detailed methods to obtain absolute values of the required cooling-air weight flow, the pressure loss, and the strength characteristics.
