Book excerpt: The effects of changes in geometry on the performance of 15 tandem-bladed stators is reported. Five geometrical parameters were evaluated for flow only in the two-dimensional plane. Using results from this study a tandem blade was designed for which the analytically calculated loss was relatively small. A parameter that approximated the incidence of the mean flow on the rear blade showed an ability to identify effective tandem blade configurations. Boundary-layer calculations indicated that the shorter chord length tandem blade segments could not sustain as high a suction surface diffusion as conventional solid blade sections.
