Résumé

Supersonic axial stages with big pressure ratio are increasingly in demand. There is a problem to elevate pressure ratio of a stage up to 3 and more. Efficiency of a stage can be limited by shock wave losses at high supersonic speeds. The numerical analysis of losses was made in a plane cascade. Calculated losses in shock waves depend on a velocity coefficient and an angle of a shock wave. Pressure loss calculation in subsonic parts of a stage was made by a loss coefficient. Its value was chosen by an expert assessment. It is shown shock that wave losses are not an obstacle for an acceptable level of stage efficiency up to a velocity coefficient value 1.5.
