Airbus researches shape-shifting wing

Airbus is researching an “extra-performance wing” capable of changing shape during flight, as part of efforts to make future aircraft more efficient and reduce carbon emissions

Wing demonstrator will be tested on Cessna Citation VII business jet

“Gust sensors”: Measure turbulence so wing control surfaces can automatically adjust, reducing need for aircraft to make detour

Demonstrator conducted under Airbus’ flying-tech subsidiary, UpNext

Multi-functional morphing trailing edges 
Dynamically change shape of wing during flight to improve overall aerodynamic efficiency of aircraft

“Semi-aeroelastic” hinged wingtips
Allows aircraft to have longer wingspan with minimal impact on weight – creating less drag

Folding wingtips also allow large aircraft to fit inside standard airport gates

Pop-up spoilers

Plates rapidly deflect at right angles to airflow, to achieve optimum performance – like a bird twisting its feathers
