Abstract: Measurements in the full-scale Vertical Wind Tunnel and in a 1:12 scale model of this tunnel were made to determine if a dynamic pressure distribution required for the spinning of airplane models could be achieved by a honeycomb of cozrventional type. Test results indicate that a minor change of the nozzle contour at the place where the honeycomb is installed is a possible means to obtain the required dynamic pressure distribution.
