Abstract : Base flow closure angle data were obtained from ballistics range and wind tunnel photographs of cones in free flight at low supersonic Mach numbers. These data were compared with laminar theory using the Chapman separated flow model and its recent extensions which take into account the structure of the initial profiles at the separation point. The ballistics range data were in good agreement with the theory which included the effect of the distortion of the boundary layer profiles due to flow turning at the separation point. This suggests that details of the structure of the initial separated shear layer profiles may be quite important in determining the overall properties of the base flow region. (Author)
