Abstract : Two-dimensional boundary layer velocity profiles, as well as pressure distributions, turbulence intensities, and Reynolds stresses were measured on a six-caliber secant-ogive model for angles of attack of 0 deg, 2 deg. Test conditions were a Reynolds number of 2.7 times 10 to the sixth feet, Mach number of 3.2, and a P of 20 psia.
