Book Description
Drag, heat transfer, and number flux were measured on sharp cones in the near free, molecule flow regime, and the results were compared with available Monte Carlo calculations. In general, the calculations predicted the magnitude of the data; however, the heat transfer and drag increased with increasing Knudsen number at a faster rate than predicted. Also the drag coefficients measured for the slender cones at high Knudsen number were higher than predicted for free molecule flow. These disagreements between theory and experiment could possibly be attributed to the simplicity of the surface interaction laws assumed in the theory. Reynolds analogy factors obtained from the experimental measurements agreed with free-molecule values and also with that obtained by the Monte Carlo technique.

Book Description
The drag forces experienced by a sphere and a sharp slender cone were measured under hypersonic rarefied flow conditions using a flow modulation technique. The resulting drag coefficients are in substantial agreement with those obtained by other investigators, and extend, by nearly two orders of magnitude in the case of the cone, to more rarefied conditions than previously reported.

Book Description
This Paper describes an experimental study performed in the RAE Low Density Tunnel to determine the aerodynamic characteristics of a range of slender axisymmetric bodies in rarefied hypersonic flow. The main purpose of this study was to assess the effects of cone angle, nose bluntness and Reynolds number on the zero incidence drag of cones. In addition, some measurements of axial force, normal force and pitching moment at incidence were made. The bodies were tested at a nominal Mach number of 10 and at flow conditions which correspond to those in the transitional rarefied flow regime. These data have been compared with correlations developed to represent the change in drag coefficient in this flow regime between continuum and free molecular flow.
