Summary

A theoretical and experimental investigation has been conducted of the pressure distribution on the surface of either a circular cylinder or a truncated cone located within the base region of another circular cylinder at Mach number 2. A similar analysis of pressure distribution was made for rearward-facing two-dimensional steps, and theoretical results were compared with experimental results of earlier investigations. Theoretical base-pressure ratios of two-dimensional steps agreed well with experimental results; however, as a result of the simplifying assumptions made for axisymmetric configurations, only a range of values for theoretical base-pressure ratio could be calculated within which the experimental results were expected to occur. The data generally followed the trends predicted by the theory, and deviations apparently could be explained.
