A STUDY OF THE SONIC-BOOM CHARACTERISTICS OF A BLUNT BODY AT A MACH NUMBER OF 4.14

摘要

An experimental and theoretical study of the sonic boom generated by a blunt body at a high supersonic Mach number has shown that the applicability of farfield sonic-boom theory previously demonstrated for more slender shapes may now be extended to bodies with ratios of diameter to length as great as two and to Mach numbers at least as high as 4.14. This finding is of special significance in view of the limitations to the use of existing methods for the extrapolation of close-in experimental data that were uncovered in the study.
