Identification of flutter margins in modern aeroelastic systems is a challenging task due to increased nonlinearities novel designs, which can result instabilities occurring below the linear speed. These pose significant risk as they may involve multiple stable solutions, such large-amplitude self-sustained oscillations. The lack efficient nonlinear bifurcation analysis methods for experimental exacerbates challenges associated with postflutter analysis. This paper presents data-driven...
Abstract Galloping is a self-excited vibration problem that structures immersed in fluid flow can experience. Due to its essential nonlinear phenomena, the structure exhibits limit cycle oscillations (LCOs), which, at high levels, lead failure of systems. This work proposes an investigation electromagnetic-enhanced energy sinks (NES-EH) for hybrid mitigation aeroelastic LCOs and harvesting. The study focuses on prismatic bluff body with linear suspension airflow, using classical steady...
This paper presents a stability robustness analysis of the helicopter ground-resonance phenomenon. By using lifting procedure uncertain linear-time-periodic model is transformed into an augmented linear-time-invariant that allows application -analysis tools. The involves periodic switching piecewise computed oversampling system period. representativeness lifted for various period values and methods discussed compared with Floquet several parametric configurations. A then applied to find...
Recent works have studied ground resonance in helicopters under the aging or damage effects. Indeed, blade lead-lag stiffness may vary randomly with time and differ from to blade. The influence of dissimilarities between blades on stability phenomenon was determined through numerical investigations into periodic equations motion, treated using Floquet's theory. A chart highlights appearance new instability zones as a function perturbation introduced one In order validate theoretical results,...
Abstract An expandable and Fire, Smoke, Toxicity (FST) compliant epoxy foam is proposed as an interesting alternative to Nomex® honeycomb cores for the development of Multi‐Functional Structures (MFS). The paper first analyzes processing conditions using several experimental techniques differential scanning calorimetry (DSC), rheology, expansion in a closed volume order evaluate reaction kinetics, chemorheological behavior, kinetics material. data are used identify empirical models...
Introdução: A Helicobacter pylori é uma bactéria gram-negativa com grande capacidade de virulência, sendo o principal fator relacionado a essa virulência gene associado à citotoxina (CagA). Embora na maioria das pessoas infecção seja assintomática, em alguns casos ela pode desencadear doenças como gastrite, úlceras gastroduodenais e linfoma do tipo MALT. Objetivo: Avaliar relação entre incidência Metodologia: Trata-se revisão integrativa base dados PUBMED utilizando os descritores...
