The Effect of Spanwise Folding on the Aerodynamic Performance of a Passively Deformed Flapping Wing
BiomimeticsThe wings of birds exhibit multi-degree-of-freedom motions during flight. Among them, the flapping folding motion and chordwise passive deformation of the wings are prominent features of large birds in flight, contributing to their exceptional flight ...

Characteristics of deploying longitudinal folding wings with compound actuation
Advances in Mechanical EngineeringA mechanism has been developed to achieve rapid deployment of longitudinally folding wings by utilizing compound actuation from the firing powder and the compressive spring. A theoretical model based on rigid-body dynamics was first proposed to study the
