Taking inspiration from bats, researchers build a flexible membrane wing that can create more lift than a stiff wing by bending and changing shape when it is flapped back and forth, causing air to flow along the wing without creating a vortex. In PNAS: www.pnas.org/doi/10.1073/...

Bat wings boost hovering efficiency
EPFL researchers have designed flexible, batlike wings that boost lift and improve flight performance. This innovation could lead to more efficient drones or energy-harvesting technologies.
Exciting to see EPFL News featuring our (@unfold-epfl.bsky.social) work on how flexible, bat-like wings generate lift more efficiently! 🦇 By bending just right, they boost performance—insights that could shape future drones & energy tech. 🚀

🚨 New paper alert 🚨
@alexandergehrke.bsky.social's work on membrane wings is now published in @pnas.org 🎉
Flexible membrane wings can outperform stiff wings and, surprisingly, they perform best when the formation of a leading edge vortex is suppressed 🌀
