摘要: The purpose of the present investigation was to establish accurate values sphere drag coefficient in flight regime 0.1 < Mx 6.0 and 2 x 10 Re^ for TJT^ % 1.0. To this end, an extensive series measurements made a ballistic range. These measurements, together with other published data, permit derivation confidents uncertainty + regime. In addition, sifficient information is presented such that reasonable estimates confident can be ^ 1.0, 0.05 M^ 20.0, 10~ Re*, W\
