The outlet fields of the annular stator cascades of a small-Size engine with conventional twisted blades and curved-twisted blades were measured in detail. By the analysis and comparison of the tested results the conclusions are obtained as fiollows:the meridian convergence of the lower endwall can improve the flow in the tip region of the cascade with conventional twisted blades. The good combine of blade curving and controlled vortex design can notably reduce the radial secondary losses and even the reaction of the turbine stage along blade hight.
