Summary report on aerodynamic characteristics of standard models HB-1 and HB-2 /

All available test data on the standard hypersonic ballistic correlation models, HB-1 and HB-2, were examined to establish reference characteristics for use in the correlation of experimental results among the various aerodynamic facilities. The data presented are comprised primarily of static stability and zero-lift forebody axial-force coefficient results at Mach numbers from about 1.5 to 20 for a Reynolds number range from 0.01 to 2700000 based on centerbody diameter. Selected pressure distribution, dynamic stability, and heat-transfer data are included. Comparisons of data from various test facilities show excellent correlation in spite of the appreciable Reynolds number dependence of test results for model HB-2 with natural boundary- layer transition."July 1964."Includes bibliograqphic references (page 8).All available test data on the standard hypersonic ballistic correlation models, HB-1 and HB-2, were examined to establish reference characteristics for use in the correlation of experimental results among the various aerodynamic facilities.
