The use of Gramian matrices for aeroelastic stability analysis
(2013-05-13)
Most of the established procedures for analysis of aeroelastic flutter in the development of aircraft are based on frequency domain methods. Proposing new methodologies in this field is always a challenge, because the new ...

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 ...
Aeroelastic behavior of a wing with a magnetorheological hysteretic model to the damping
(2011)
This paper shows the application of a hysteretic model for the Magnetorheological Damper (MRD) placed in the plunge degree-of-freedom of aeroelastic model of a wing. This hysteretic MRD model was developed by the researchers ...
A reduced order state space model for aeroelastic analysis in time domain
(2017-02-01)
The objective of this paper is to describe a new method for modeling aeroelastic system in time domain based on a modification of the Laguerre Polynomials to represent complex quantities. These polynomials are used to ...
Influence of structural nonlinearities in stall-induced aeroelastic response of pitching airfoils
(European Assoc Structural Dynamics, 2014-01-01)
Stall-induced vibrations are a relevant aeroelastic problem for very flexible aero-structures. Helicopter blades, wind turbines, or other rotating components are severely inflicted to vibrate in stall condition during each ...

Chaotic Patterns in Aeroelastic Signals
(HINDAWI PUBLISHING CORPORATION, 2009)
This work presents the analysis of nonlinear aeroelastic time series from wing vibrations due to airflow separation during wind tunnel experiments. Surrogate data method is used to justify the application of nonlinear time ...
A note on typographical errors defining Theodorsen's coefficients for aeroelastic analysis
(Sage Publications Ltd, 2018-05-01)
The problem of flutter is an important topic involving aeroelastic analysis. The first approach to studying this problem was proposed by Theodore Theodorsen in 1935 and, since that publication, Theodorsen's theory has been ...
