Improving the accuracy of production wind tunnel testing for commercial and business aircraft

点击翻译按钮获取中文摘要

The aerodynamic design of commercial and business aircrafts requires a careful mix of computational analysis and experimental testing to ensure a timely market delivery at a limited level of risk. Ground test facilities like wind tunnels continue to provide the bulk of experimental data that are used to calibrate CFD codes, validate the aerodynamic design, and generate the aerodynamic database necessary to implement flight control systems. In recent years, market dynamics have provided a strong incentive for aircraft manufacturers to reduce the design cycle time while simultaneously maintain or even reduce the amount of risk associated with aerodynamic design. This is a challenging environment for wind tunnel operators, who are constantly confronted with simultaneous requests for increased efficiency and reduced uncertainty in aerodynamic testing.
