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 ...
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 ...
A Numerical Study of a Rotor Induced Flow Based on a Finite-State Dynamic Wake Model
(Sociedade Brasileira de Matemática Aplicada e Computacional - SBMAC, 2021-07-02)
A Helicopter rotor undergoes unsteady aerodynamic loads ruled by the aeroelastic coupling between the elastic blades and the dynamic wake induced by rotary wings. Modeling the dynamic interaction between the structural and ...
