WIND TUNNEL FLUTTER TEST OF AEROELASTIC MODEL AE1 SUCCESFULLY COMPLETED!

May 2023

The first week of May, 2023, the flutter test of aeroelastic model AE1 has been successfully completed at POLIMI’s Large Wind tunnel. Different velocities, angles of attack as well as chordwise positions of the strut- wing connection have been successfully tested. The identification phase has been carried out combining an air jet nozzle to excite the model with modern Output only Modal Analyses (OMA) techniques in case of turbulence based self-excitation. Classical piezoelectric accelerometers as well as camera based photogrammetric techniques have been adopted as measurement systems.

U-HARWARD will consider the use of innovative aerodynamic and aeroelastic designs in a multi-fidelity multi-disciplinary optimal design approach to facilitate the development of Ultra-High aspect ratio wings for large transport aircraft. A conceptual design study, building on the current state of the art, will perform trade-off studies to determine the potential gains of different wing configurations and loads alleviation concepts in terms of aerodynamics, weight, noise, fuel-burn and range. Scaled model wind tunnel tests will be used to validate parametric variations in the aerodynamic and acoustic characteristics. Starting from a reference aircraft, the preliminary design of the best candidate configuration will be completed and the estimated gains validated using high fidelity tools and a larger scale aeroelastic test.
