Based on numerical simulations, the losses mechanisms generated in supersonic turbine rotors are studied. The flow pattern is mainly characterized by the presence of shock waves which are responsible of the most part of the losses. The contributions of aerodynamic conditions and geometrical parameters are evaluated for different typical rotor blade. The study concludes that the shock waves are the main origin of the losses.
