The design of supersonic turbines for the Ariane 5 rocket motor is discussed. From the specification an optimization study was carried out. Influence factors led to requirements on the turbines where functions combining turbine weight, performance, development cost, production cost, and program risk were optimized. The full scale turbine produces a specific torque 7% lower than the subscale turbine. The performance is shown to be lower for both the stator and the rotor. Deviations which may explain the reduced performance are detailed.
