Abstract:

This report presents a technical evaluation and assessment of the AGARD Fluid Dynamics Panel Symposium on Aerodynamic Data Accuracy and Quality Requirements and Capabilities in Wind Tunnel Testing, held in September 1987 in Naples, Italy. The major issues addressed were what data accuracy do users need what accuracy is presently achieved and what can be done to improve the situation Users have asked that cruise drag be measured to a precision of one drag count for transports and two for military fighters and it was shown that this is possible when reference methods can be used. However, one or two drag count uncertainty is not state-of-the-art for the direct scaling concept and improvement will require a thorough understanding of all those parameters which significantly contribute to wind tunnel uncertainty, including bias and precision. A reduction in total uncertainty appears possible but a reduction to a level of one or two drag count also appears formidable. Keywords Aerodynamic characteristics Accuracy Wind tunnel tests Precision Measurement NATO furnished.
