Airbus is moving ahead with its vision of aircraft with active wing control, following successful wind tunnel tests at its facility near Bristol, England. The company is working to mimic the behavior of bird flight with wings that adapt their shape on the fly to optimize aerodynamics, making for more efficient aircraft with lower carbon footprints.The eXtra Performance Wing project was borne out of a similar Airbus project called AlbatrossOne, which in 2019 saw engineers fly a scale-model airplane with flapping wing tips.…
