Conceptual study of a morphing winglet based on unsymmetrical stiffness [PDF]

, 2016
Morphing technology has the potential to increase aircraft performance. Among the morphing technologies, the morphing winglet is a promising solution due to its small size and large effect on the aerodynamics. Morphing winglets have to carry the spanwise

Basal complex: a smart wing component for automatic shape morphing

Communications Biology, 2023
Insect wings are adaptive structures that automatically respond to flight forces, surpassing even cutting-edge engineering shape-morphing systems. A widely accepted but not yet explicitly tested hypothesis is that a 3D component in the wing’s proximal ...
