Abstract

Dispositif pour réduire, dans une chambre d'essais de soufflerie, les effets de bord dus à la limitation des dimensions de cette chambre. Il comporte un ensemble d'éléments longitudinaux plans et rigides 3 juxtaposés pour former au moins une paroi horizontale 5, verticale 4 ou inclinée, chacune des deux extrémités 3a, 3b de certains au moins de ces éléments longitudinaux 3 étant reliée à un point 7 fixe dans l'espace par l'intermédiaire d'un organe de réglage 9 permettant de modifier, pour lui donner des caractéristiques finales déterminées, le vecteurDevice for reducing, in a wind tunnel test chamber, the edge effects due to the limitation of the dimensions of this chamber. It comprises a set of flat and rigid longitudinal elements 3 juxtaposed to form at least one horizontal wall 5, vertical 4 or inclined, each of the two ends 3a, 3b of at least some of these longitudinal elements 3 being connected to a fixed point 7 in space by means of an adjustment member 9 making it possible to modify, in order to give it determined final characteristics, the vector
