Abstract
Die Erfindung betrifft eine Messstrecke fuer Windkanaele fuer aeroakustische Messungen, wobei um das Messobjekt ein einen Kanal bildendes ganz oder teilweise akustisch transparentes Flaechengebilde angeordnet ist.

 

DE 19939196 A UPAB: 20010809 NOVELTY - The wind tunnel has an aero acoustic measurement section that has a partial acoustically transparent area forming a channel. A measurement object is placed in the channel of the measurement section. USE - For aero acoustic investigation. ADVANTAGE - Ensures improved measurement with reduced noise levels. Optimizes necessary divergence for various test items with computational paths. Ensures small wall friction and pressure loss due to low coarseness of walls inside measurement area.
