Shape-morphing structures based on pressure actuation promise efficiency gains and
performance improvements in aeronautics, but require complex three-dimensional …

Several modeling extensions and numerical improvements to the unsteady vortex-lattice
method are discussed for the simulation of very flexible aircraft dynamics. In particular …

Folding wingtips address the challenges posed by high-aspect-ratio wings, such as airport
conformity and increased wing root bending moment. Actuated adaptive wingtips extend the …

Increasing the aspect ratio is one way to improve aircraft aerodynamic efficiency. This
reduces the induced drag term but, at the same time, produces an increment of the wing …
