Efeitos da aplicação de piezocerâmicas no comportamento aeroelástico de rotores submetidos ao whirl-flutter
Bastos, Sérvio Túlio Suenai Haramura
; De Vasconcellos, Rui Marcos Grombone (Workshop pós-graduação Unesp, 2022) [Artigo]
Com o advento da mobilidade aérea do futuro torna-se fundamental a análise de táticas de controle vibracional para o desenvolvimentos de aeronaves mais eficientes. Sendo que a aplicação de piezoelétricos para o controle ... -
Vibrações induzidas por vórtice em um cilindro com um grau de liberdade e rigidez não linear
Bastos, Sérvio Túlio Suenai Haramura; De Vasconcellos, Rui Marcos Grombone ; (Congresso Ibero-Americano de Engenharia Mecânica, 2019) [Artigo]
In this research project, it is proposed an investigation of the effects of hardening structural nonlinearity in a single degree of freedom cylinder exposed to a transverse flow, presenting the vortex induced vibration ... -
Amplitude reduction through energy harvesting in vortex-induced vibrations
Bastos, Sérvio Túlio Suenai Haramura; De Vasconcellos, Rui Marcos Grombone (International Conference on Advances in Energy Harvesting Technology ICAEHT 2021, 2021) [Artigo]
In this work, an identified electrical-mechanical model is implemented to describe complex behavior, such as upper and lower branches, and the piezoelectric coupling to harvest electric power in a 1DOF cylinder exposed to ... -
Effect of Coriolis acceleration on the span-wise vorticity field over a wind-turbine airfoil
Rodrigues, Pedro Trombini; Gennaro, Elmer Mateus ; Souza, Daniel Sampaio (AIAA, 2022) [Artigo]
The rotation is known to reduce the volume of the region of separated flow on inboard sections of horizontal-axis wind turbine blades. This reduction is frequently attributed to centrifugal pumping. However, recent ... -
Blade Element Momentum simulations using polars extracted from wind-turbine-model experiments
Rodrigues, Pedro Trombini; ; Pagani Júnior, Carlos do Carmo ; Sampaio, Daniel Souza (ABCM, 2021) [Artigo]
Due to rotational effects, the observed load of inboard sections of rotary wings is consistently higher than the load predicted based on the two-dimensional aerodynamic behavior of the corresponding airfoil in linear motion. ... -

Orbital maneuvers for asteroids using genetic algorithm
Neves, Guilherme Marcos; Santos, Denilson P. S. ; Domingos, Rita de C. ; Formiga, Jorge K. S. (Journal of physics: conference series, 2019) [Artigo]
Near Earth objects (NEOs) are comets and asteroids that orbit the vicinity of the Earth. The scientific interest in comets and asteroids is due in large part to their status as remnants remaining relatively unchanged from ... -
Tension force in nanosatellite tethers systems
Moia, Guilherme Parreira; Santos, Denilson P. S. ; Formiga, Jorge K. S. (Journal of physics: conference series, 2019) [Artigo]
The use of innovative technologies in space missions has evolved considerably in the last decade. The use of large cables in space structures to connect spacecrafts and satellites with the goal to minimize cost of missions ... -

A variety of nonlinear features is obtained from aeroelastic systems with discontinuous nonlinearity motivates investigations that may support future applications in controls design, flutter prediction problems, and energy ... -
Influence of structural nonlinearities in stall-induced aeroelastic response of pitching airfoils
; Vasconcellos, Rui M. G.; (Eurodyn 2014: Ix International Conference On Structural Dynamics, 2014) [Trabalho apresentado em evento]
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 ... -
Compressible modes in a square lid-driven cavity
; Gennaro, Elmer Mateus; ; (Aerospace Science And Technology, 2015) [Artigo]
This paper studies the effect of compressibility on the linear stability of a two-dimensional lid-driven cavity flow in the subsonic regime. The base flow is generated by high fidelity direct numerical simulation and a ...
