Experimental results are presented that show the existence of organized structures in a compressible, turbulent boundary layer. Results were obtained using arrays of hot wires and wall pressure transducers in a Mach 3 zero pressure gradient boundary layer. The inferred angle from correlations between two hot wires, and between a hot wire and a wall pressure transducer, indicate that the average structure is inclined at approxinately 45DEGREES for a large part of the boundary layers. Measurements of the instantaneous angle show a wide distribution of structure angles, and the general behaviour of the large scale structures is consistent with the hairpin loop model of wall turbulence.
