Abstract
For evaluate the aerodynamic character of the turbine cascades which have the aft-loaded profile, the experimental investigation is carried out on the low speed annular wind tunnel. And the detailed measurements of the aerodynamic parameters are made from upstream to downstream of the two type turbine cascades, the one is the conventional straight blades cascade, the other is the curved blades cascades. The static pressure distributions on the endwall and the blade surface are also carried out. The influence of the aft-loaded profile and the curved blade on the development of loss and the pressure distribution is discussed, and the different flow phenomena and mechanism in two type turbine cascades are analyzed.
