Abstract:

Boundary layer measurements have been carried out on a sharp-edged delta wing with turbulent boundary layers. From the velocities at the outer edge of the boundary layer on the upper and the lower side of the wing the bound vortex lines in the lifting surface were determined. A comparison with former investigations concerning laminar boundary layers shows the influence of the status of the boundary layer on the vortex formation. Investigations of the flow downstream of the wing trailing-edge indicate, that the trailing vortex sheet rolls up into a vortex, the rotation of which is opposite to that of the leading-edge vortex. The axis of this so called trailing-edge vortex forms a spiral within the leading-edge vortex. Author
