Journal ArticleDOI
Influence of flexibility on the aerodynamic performance of a hovering wing.
TL;DR: It was found that flexibility can enhance aerodynamic performance and that the best performance is realized when the wing is excited by a non-linear resonance at 1/3 of the natural frequency, which points to the importance of considering non- linear resonances for enhancing aerodynamics performance.
Journal ArticleDOI
A strongly coupled, embedded-boundary method for fluid–structure interactions of elastically mounted rigid bodies
TL;DR: In this paper, the Navier-Stokes equations for incompressible flow are solved on a Cartesian grid which is not aligned with the boundaries of a body that undergoes large-angle/large-displacement rigid body motions through the fixed grid.
Journal ArticleDOI
Nonlinear free and forced oscillations of piezoelectric microresonators
TL;DR: In this article, a refined integro-partial differential model is developed for a clamped?clamped composite beam structure and used for studying the nonlinear transverse vibrations of these resonators.
Dissertation
Numerical Simulations of Interactions Among Aerodynamics, Structural Dynamics, and Control Systems
Journal ArticleDOI
Novel Strategy for Suppressing the Flutter Oscillations of Aircraft Wings
TL;DR: In this paper, a nonlinear phenomenon of saturation is proposed for controlling the flutter of a wing, which is illustrated by means of an example with a rather flexible, high-aspect wing of the type found on such vehicles as high-altitude long-endurance aircraft and sailplanes.
