Technical Evaluation Report on the Fluid Dynamics Panel Symposium on Aerodynamic Data Accuracy and Quality: Requirements and Capabilities in Wind Tunnel Testing

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.
