Abstract:

A procedure has been developed for designing supercritical cascade airfoils satisfying practical aerodynamic and structural requirements. The purpose of the research reported herein is to improve the calculation of flow turning and profile loss for these airfoils through the use of a model of the viscous wake. Wakes were measured in a large-scale, low-speed facility for two cascades. The first cascade configuration was a fore-loaded supercritical design the second was a conventional aft-loaded design. The experimental results were used to analytically model the viscous wake in an inviscid potential flow calculation.
