Preliminary Surveys of the Three Dimensional Boundary Layer on a Yawed, Spinning Body of Revolution
Abstract
Experimental measurements of the three dimensional boundary layer on a yawed, spinning tangent-ogive-cylinder model in supersonic flow are reported. The measurements were made using a flattened total head probe at one axial station near the base of the model for 10 azimuthal stations about the circumference. The test conditions were: M = 3, angle of attack = 4 deg, omega = 0 and 10,000 RPM. The trends observed in comparing measurements with and without the model spinning were: (1) the boundary layer is more thick and less full where surface spin opposes the crossflow velocity; and (2) the boundary layer is less thick and more full where surface spin is in the same direction as the crossflow velocity.
