The dynamic stall phenomenon is present in many engineering problems and its prediction represents a great modeling challenge. Working airfoils in the dynamic stall condition can lead to serious aeroelastic vibration problems or loss of aerodynamic efficiency. The various physical events that result from airfoils dynamic stall imply in difficulties in the preparation of a mathematical mod…
The objective of this proposal is for FAPESP financial support in order to make possible the technical visit of Prof. Muhammad R. Hajj, during the period October 28 to November 8, 2013, under the coordination of Dr. Flávio D. Marques, and to address issues related to academic and research cooperation in nonlinear aeroelasticity. They are also planned other activities such as short-course …

The search for more flexible aeroelasticity structures drive the study of dynamic stall phenomena. In this research project, the objective is to obtain the optimal parameters of a Beddoes e Leishman semi-empirical model to predict aerodynamic loads caused by the dynamic stall for a serie of aerodynamic profiles. For this purpose, an algorithm using Genetic Algorithm (GA) and supervised ma…
As the search for more flexible aircraft structures increases, so does the need to incorporate the intrinsic nonlinearities in their aeroelastic analyses. In that manner, it becomes essential to fully characterize the aeroelastic behavior and to investigate the effects that common external disturbances, such as atmospheric gust turbulence, might induce in flight dynamics. Hence, the prese…
Vortex shedding in the flow during unsteady aerodynamic phenomena gives rise to deviations from the expected static behavior. This type of event can be harmful as it can cause undesired vibrations and load spikes. In this sense, the appearance and development of leading-edge vortices are of great interest to the field of unsteady aerodynamics. In the LDVM model (LESP-modulated discrete vo…
Fluid flow can be responsible for vibrations in structures, as happens in the phenomena of Vortex-Induced Vibrations in immersed bodies and galloping in eletric transmission lines. These mechanical vibrations are an important topic in several engineering areas, since they can lead to structural fatigue and catastrophic failures. Thus, the study of their control is of interest. This resear…
Shimmy is an aeromechanical phenomenon characterized by a potential for instability in aircraft landing gears, even when they are in contact with the ground. The appearance of this phenomenon reveals a self-excitation mechanism. High levels of vibrations are observed in the aircraft's landing gear, which can cause fatigue and structural limb failures, and therefore are undesirable and mus…
The fluid-structure interaction often leads to undesirable consequences, such as divergence, command reversal and flutter and therefore needs a deeper analysis, taking into account the effects not predicted by classical theories. Thus, reliable models are needed that can predict the physical behavior of devices that operate at high angles of attack or high frequency movements. The present…

The proper analysis of high-angles of attack, large-amplitude, and high-frequency aircraft wings maneuvers needs models that correctly account for the nonlinear effects of the vortical structures developed in unsteady phenomena. Although the CFD methods are exceptional in analyzing unsteady flows, they require high computational power. Meanwhile, low-order methods showed noteworthy perfor…
Aircraft flexibility has been trending upwards as the performance requirements are pushed to the limits. At the core of the associated aeroelastic challenges are the consideration of nonlinearities arising from large displacements and separated airflow, and a suitable model for the prediction of gust-induced instabilities. The present research proposal aims to build an enhanced computatio…
Aeroelastic systems can operate in a self-excited mechanism. Under this condition, these can exhibit self-sustained oscillations resulting in a catastrophic unstable behavior or undesired limit cycle oscillations (LCOs). The mitigation and/or harvesting process of the energy contained in the structures when these phenomena take place has been received significant interest from the researc…
The present research project proposes the improvement of a semi-analytical inviscid model for two-dimensional separated flow over an unsteady airfoil. The potential theory, the Kutta condition and the Joukowsky transformation between a circle and the plate cross-section were used, being analyzed the kinematic and dynamic characteristics of the flow for high angles of attack. This work com…
