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 electrification of the aviation has brought new aircraft configurations, which generally have lightweight wings with high aspect ratios. These wings tends to be more flexible, which makes them susceptible to large displacements when in operation. Because of that, it's essential to consider their geometric non-linear behavior on the simulations. Furthermore, in the case of the so-calle…
Aeroelastic oscillations control is of great interest due to their high amplitudes self-excited and self-sustained behavior. In this context, passive control methods are interesting due to their simplicity and lack of dependence on external energy sources, such as nonlinear vibration absorbers known as Nonlinear Energy Sinks (NES), in which a secondary mass is attached to the structure th…
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…

Aeroelasticity is an area of science that leads to problems involving the interaction between inertial, elastic, and aerodynamic forces. It determines and explains the causes of many phenomena. One of the most important is the flutter. This interaction between structure (inertial and elastic forces) with the flow (aerodynamics forces) is characterized as an unstable oscillation and auto-e…
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…
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…

The electrification of aviation has led to new aircraft configurations that generally feature light wings with high aspect ratios coupled with several propellers along the wing span. When it comes to the so-called HALE (High-Altitude Long-Endurance) and EVTOLs (Electrical Vertical Take-Off and Landing) aircraft, the problem becomes even more complex, and the aeroelastic behavior of the sy…
In applied sciences, it is common to have a general system of governing equations that describe the behavior and development of the dynamical system. But, thisset of equations is derived from conservation laws, positing empirical relations betweenvariables or through asymptotic reductions. Such a problem is also present in complexaeroelasticity analyses. Therefore, considering a two-degre…
Structural dynamics is an important topic in several engineering fields once dynamic loading becomes a reality in most applications, which can lead to instability or fatigue in components, compromising their operability. Several active and passive methods for controlling unwanted vibrations have been developed over the years. Among them, passive control is promising because it does not de…
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…
