Flutter and Divergence Characteristics of Composite Plate Wing

Flutter Analysis of a Low Aspect Ratio Swept- Back Trapezoidal Wing at Low Subsonic Flow

A linear, aeroelastic analysis of a low aspect ratio swept back trapezoidal wing modeled as a cantilever plate is presented. An analytical and numerical formulation for both the aerodynamic forcing and structural response of the wing was developed. The analytical model uses a three dimensional time domain vortex lattice aerodynamic method. A Rayleigh-Ritz approach has been used to transfer equa...

Flutter Modeling and Simulation of Wing Section Using Bondgraph Technique

ACKNOWLEDGMENTS I would first like to thank my family especially my parents for instilling at a very young age the many important lessons and positive aspects of life, which plays a crucial role in who I am today. I would also like to give special thanks to my friends, who gave me a lot of help in completing my research and also to The Public Service Department and U.S.M. for the sponsorship of...

Analytical buckling and post-buckling characteristics of Mindlin micro composite plate with central opening by use of nonlocal elasticity theory

The effect of central opening on the buckling and nonlinear post-buckling response of carbon nanotubes (CNTs) reinforced micro composite plate embedded in elastic medium is considered in this paper. It is assumed that the system is surrounded by elastic medium, therefore; the influence of Pasternak foundation on buckling and post-buckling behavior are analyzed. In order to derive the basic form...

Derivative Measurements and Flutter Tests on a Model Tapered Wing

Calculation of Wing Flutter by a Coupled Fluid-Structure Method

An integrated computational  uid dynamics (CFD) and computational structural dynamics (CSD) method is developed for the simulation and prediction of  utter. The CFD solver is based on an unsteady, parallel, multiblock, multigrid Ž nite volume algorithm for the Euler/Navier–Stokes equations. The CSD solver is based on the time integration of modal dynamic equations extracted from full Ž nite e...
