Heat Transfer, Surface Pressure, and Boundary-Layer Surveys on Conic and Biconic Bodies with Boundary-Layer Trips at Mach 6. Phase 2

Abstract

Heat transfer, surface pressure, and boundary-layer surveys were obtained on a 7-deg cone as well as 10.5/7 deg and 14/7-deg biconic bodies. These data were obtained to determine the influence of boundary-layer trips on boundary-layer characteristics when compared with a naturally turbulent boundary layer. Flow field measurements included pitot-pressure, total temperature, and Preston tube data. Surveys were performed at several longitudinal stations along the bodies. Boundary-layer trips consisted of Carborundum grit bonded to the nose tips or a single row of spherical elements. Data were obtained at a nominal Mach number of 6 at free-stream Reynolds numbers of 2,5000,000 and 4,700,000 per ft. A variety of nose bluntness and trip combinations were tested at zero angle of attack.
