Current economic constraints and environmental regulations call for design of more efficient
aircraft configurations. An observed trend in aircraft design to reduce the lift induced drag …

Flutter is a dynamic aeroelastic instability driven by the interaction of inertial, elastic, and
aerodynamic forces. It is an undesirable phenomenon in aircraft because it causes divergent …

This is an introduction and overview of the work that has been done in nonlinear
aeroelasticity prior to the last decade. Many of the issues discussed here are still under …

The unsteady vortex-lattice method provides a medium-fidelity tool for the prediction of non-
stationary aerodynamic loads in low-speed, but high-Reynolds-number, attached flow …

ON 17 DECEMBER 1903, the Wright brothers set about the task of launching an airplane
into the sky. Their multiple successes that day have been hailed as the start of heavier-than …

Theoretical development of a nonlinear aeroelastic analysis for high-aspect-ratio wings is
presented. The analysis couples a geometrically exact beam theory with a nonplanar …

HIGH-ALTITUDE long-endurance (HALE) vehicles feature wings with high-aspect-ratio.
These long and slender wings, by their inherent nature, can maximize lift-over-drag ratio. On …

The paper presents results obtained for limit-cycle oscillations (LCOs) in high-aspect-ratio
wings caused by structural and aerodynamic nonlinearities. The analysis is based on …

Aeroelasticity is still dynamic, challenging, and a key part of cutting-edge airplane
technology. Emerging trends, as well as challenges and needs in the eld of airplane …
