Abstract : An apparatus was designed to measure local skin friction near the sharp leading edge of a flat plate by the floating element technique in a low density Mach 6 wind tunnel. It was found that the accuracy of the data was strongly influenced by extremely small irregularities on the model surface. It was concluded that further model refinement was needed. Even though the data were of marginal quality they suggested that the skin friction was less than predicted by strong interaction boundary layer theory. (Author)
