Surface Pressure Measurements on Slender Bodies at Angle of Attack in Supersonic Flow

Abstract

Measurements of wall static pressure on the surface of bodies with both secant and tangent ogive noses and with both straight tails and boattails are reported. Data were taken at three supersonic Mach numbers (2, 3, and 4) and at six angles of attack (0, 1, 2, 4, 6, and 10 degs). Pressure data were obtained at ten longitudinal stations along the models. The models were rolled to obtain data at azimuthal positions every 10 degs about the body. Some comparisons of the data with numerical computations based on inviscid theory are given. These comparisons show good agreement at small angles of attack.
