The paper shows some results from the experimental testing of a turbine stage equipped with 3D shaped stator blades. Data measured behind the stator and rotor clearly revealed the difference between Compound Lean and Compound Twist blades. The effects of the 3D stator shaping on flows are presented in comparison with classical Prismatic blades. The design of a new stage with 3D shaped stator and also rotor blades is described.
