Full text not available from this repository.
Selected results of 2D wall interference studies in the new variable slot width and shape transonic test section of the VKI-S1 wind tunnel are introduced. It was found that overall wall interference could be minimized but significant gradients remained. In addition to airfoil and wall pressures, detailed plenum pressures were recorded. They indicated unfavourable wall/plenum pressure gradients in certain areas which did not support the wall cross flow direction needed for a further reduction of the wall interferences. A two chamber arrangement per horizontal wall is suggested. Supporting detailed results on wall and plenum pressures, actual and needed wall cross flows, and needed suction or blowing rates are provided.
