Relatively narrow space for aerodynamic design of long rotor blades applied at last stages of large output steam turbines often results in blades with tips operating at supersonic regimes. This brings number of problems. Main of these are additional sources of loss and rather thin border between sections operating under turbine and compressor regimes one adding to performance and the other deteriorating it. Therefore, aerodynamic cascade data on turbine blading for a range of supersonic inlet and outlet conditions are needed. However, ensuring specified supersonic conditions in a high-speed wind tunnel for blade cascade tests is not an easy task and thus it deserves attention.
