Effect of engine location on flutter speed and frequency of a tapered viscoelastic wing
May 2018 • Youssef S. Matter, Tariq Darabseh, Abdel‐Hamid I. Mourad
The flutter of a tapered viscoelastic wing carrying an engine and subjected to a follower thrust force is investigated. The wing is considered as a cantilever tapered Euler-Bernoulli beam, made of a linear viscoelastic material where Kelvin-Voigt model is assumed to represent the viscoelastic behaviour of the material. In addition, quasi-steady and unsteady aerodynamic forces models are introduced along with the follower thrust force. The mass and inertia of the engine are modelled in order to achieve more realist…
