Bioinspired morphing wings for extended flight envelope and roll control of small drones
TL;DR: A novel morphing wing design composed of artificial feathers that can rapidly modify its geometry to fulfil different aerodynamic requirements is described and shows that a fully deployed configuration enhances manoeuvrability while a folded configuration offers low drag at high speeds and is beneficial in strong headwinds.
