Jet-boundary corrections for complete and semispan swept wings in closed circular wind tunnels

James C. Sivells, Rachel M. Salmi
Sep 1951

Tables and curves are presented which give values of the induced-upwash-velocity factors, due to the jet boundary, at the horizontal center plane of a closed circular wind tunnel and at that of a closed bipolar wind tunnel which is formed when a reflection plane is installed in a circular tunnel for testing semispan wings. These velocities have been calculated for infinitesimal-span lifting elements located at various points in the horizontal center plane.
