The aerodynamic characteristics of two standard, hypervelocity, ballistic-type models, designated HB-1 and HB-2 were investigated in the supersonic and hypersonic regimes. The tests were conducted at nominal Mach numbers of 1.5, 2, 3, 4, 5, 8, and 10 at Reynolds numbers from 0.07 to 2.55 x 10 to the 6th power, based on body diameter, and through an angle-of-attack range from -2 to 15 deg. The effects of Mach number, Reynolds number, and model attitude on the static stabil ity and axial-force characteristics of the two configurations were investigated. The zero-lift, forebody, axial-force coefficient, CA, for both configurations was found to be sensitive to Reynolds number variations; whereas the initial normal-force curve slope, CN alpha, and center of-pressure, xcp/l, for only the flared-tail model (HB-2) were dependent upon the Reynolds number.
