Aerodynamic Data Accuracy and Quality: Requirements and Capabilities in Wind Tunnel Testing.
Abstract
The wind tunnel continues to be the main instrument for providing experimental aerodynamic data for the purpose of load and performance evaluation and for verification of theoretical results. In both cases it is imperative that the user has confidence in the quality of the results, which means that they must have information as to what accuracy to attach to the data. The quality of wind tunnel results depends upon both the accuracy of measurements and the imperfections provided by the wind tunnel environment. It was the purpose of this symposium to try to define what accuracy has presently been achieved in modern facilities and to compare these achievements with the actual demands of the user. Session topics included: Wind tunnel data comparisons; Uncertainties analysis; Drag accuracy achievements; Facility problems; Simulation problems; Progress in testing techniques; Requirements. Keywords: Wind tunnel test methods; West Germany; Great Britain; france; Transonic airfoils; Wing body configurations; Wind tunnel models; Jet transport aircraft; Aerodynamics; Transonic Wind tunnels; Measurement uncertainty; Aerodynamic drag estimates; Civil aviation; Unsteady flow; Wind tunnel nozzle design; Boundary layer interference; Wind tunnel walls; Computational fluid dynamics; Air flow corrections; Reynolds number; Boundary layer transition; Hypersonic wind tunnels; Flow fields; Computerized thermography; Boundary layer separation.
