Passive Morphing in Insect Wings: From Biological Mechanisms to Aerospace Structures.

Passive morphing enables insect wings to adapt their shape under aerodynamic and inertial loads without direct actuation, contributing to efficient, stable, and agile flight. These natural mechanisms have attracted growing interest as a source of inspiration for adaptive aerospace structures. This review examines the s...
