An analytical investigation was conducted to provide a method for determining the cooling-air requirements for transpiration-cooled turbine stator and rotor blades for practically all engine and flight operating conditions, and the cooling-air requirements were evaluated for typical cases to determine trends that would be encountered for a wide range of variables.
