Free oscillation pitch-damping measurements were made on a nine degree half-angle cone at a Mach number of 8.0. The report discusses the design of the support, the water cooling system and its effectiveness in controlling the thermal environment of the bearings. In addition, an outline is given of a theoretical technique for calculation of the damping in pitch derivative for slender cones called the shock expansion method. Comparisons are made between theory and experiment. (Author).
