Novel approach to better evaluate air transport system aerodynamics

An EU initiative has improved the aerodynamic analysis of aeronautical transport systems by contributing to the development of optimised experimental diagnostics.

The introduction of new diagnostic techniques in wind tunnels, such as particle image velocimetry (PIV) and pressure-sensitive paint (PSP), has advanced the range of diagnostics with major tools for understanding critical aerodynamic phenomena. At present, PIV is the major diagnostic method to obtain the mean flow-field and turbulent fluctuations. The surface pressure can be measured non-intrusively with PSP, but there is essentially no means to conveniently access the pressure inside the flow.
