STS425A Disruptive Aircraft’s Wing design through innovative Electroactive Morphing towards sustainable aviation I
Mr. Yannick Hoarau (University of Strasbourg , France) , Ms. Marianna Braza (INPT , France)
The present STS at ECCOMAS 2025 will include five contributions concerning novel wing morphing, able to drastically increase the aerodynamic performances leading to a considerable fuel’s consumption decrease and noise sources reduction. Emphasis will be attributed in the efficiency of multiscale electrical actuations with increased DoF over strategic areas of the lifting structures, able to attenuate harmful instabilities and optimise the fluid-structure interaction system by means of AI. These objectives are inscribed in the HORIZON-EIC-2023-2027-PATHFINDER Project N° 101129952 – BEALIVE, "Bioinspired Electroactive multiscale Aeronautical Live skin, http://horizon-europe-bealive.eu/ . The presentations will analyse the morphing effects on the fluid-structure interaction, beneficially manipulating the surrounding turbulence towards simultaneous drag reduction, increase of lift and noise sources attenuation. The new morphing designs ensure a considerable energy decrease for the propulsion, beneficial for all sources of renewal energy. The presentations will demonstrate through well focused experiments on morphing wing prototypes and High-Fidelity numerical approaches, the effects of Travelling Waves (TW) and Standing Waves (SW) produced by the “live-skin”, as well as by other novel morphing concepts thanks to new generation of smart actuators. These designs are able to produce optimal interfacial layers interacting with the coherent and chaotic turbulence structures and applying deformation of strategic parts of the wing. The topic of this session prepares future wing design for aeronautics industrial applications aiming at saving energy and at reducing the pollution through these new, multiple-degrees-of freedom morphing concepts, enabling a considerable reduction of emissions, reaching ACARE’s European Commission targets (DG MOVE/ DG RTD, (https://data.europa.eu/doi/10.2777/15458) Flightpath 2050 that include a 80% reduction in CO2 emissions per passenger kilometers to support the Air Transport Action Group target: “Carbon-neutral growth starting 2020 and 90% or practically zero CO2 emission reduction by 2050”, as well as a 90% reduction in NOx emissions and noise emissions reduced by 65%..
