Unsteady and non-linear aeroelastic analysis of large horizontal-axis wind turbines
(Pergamon-Elsevier Science Ltd., 2014-01)
Analysis results, obtained from numerical simulation, for non-linear and unsteady aeroelastic behavior of large horizontal-axis wind turbines are presented in this paper. Simulations are carried out using a partitioned ...
A co-simulation methodology to simulate the nonlinear aeroelastic behavior of a folding-wing concept in different flight configurations
(Springer, 2019-10)
A methodology to simulate the unsteady, nonlinear aeroelastic behavior of a folding-wing concept in multiple flight configurations is presented. It is based on a partitioned or co-simulation scheme, which divides the ...
Control-Surface Structural Nonlinearities in Aeroelasticity: A State of the Art Review
(Amer Inst Aeronautics Astronautics, 2022-02-16)
This paper presents a review and assessment of more than six decades of research in aeroelastic stability, including control-surface nonlinearities. The work covers free play, friction, cubic stiffness, and an actuator in ...
Fluid-structure interaction study of the start-up of a rocket engine nozzle
(Elsevier, 2010-08)
The aim of this paper is to analyze the aeroelastic processes developed during the starting phase of a rocket engine via a coupling fluid/structure code. This analysis gives a better understanding of the behavior of the ...
Influence of friction and asymmetric freeplay on the limit cycle oscillation in aeroelastic system: An extended Henon's technique to temporal integration
(Elsevier B.V., 2020-07-01)
Nonlinear effects such as friction and freeplay on the control surfaces can affect aeroelastic dynamics during flight. In particular, these nonlinearities can induce limit cycle oscillations (LCO), changing the system ...

Aeroelastic deformation of a perforated strip
(Amer Physical Soc, 2018)
We perform a combined experimental and numerical investigation into the static deformation of perforated elastic strips under uniform aerodynamic loading at high-Reynoldsnumber conditions. The static shape of the porous ...
