TIME-DOMAIN AEROELASTIC ANALYSIS OF AGARD 445.6 WING
Author(s): Parameshwar Banakar* and Dharmendra A Ponnaswami
A coupled computational fluid dynamic (CFD) and computational structural dynamics (CSD) method is developed
for the simulation and prediction of flutter of an aircraft wing. The CFD solver is based on an unsteady transient
flow finite volume algorithm for the Navier–Stokes’s equations. The CSD solver is based on the time integration of
modal dynamic equations extracted from full finite element analysis. A general remeshing and spring analogy mesh
deformation methods are used to generate dynamically moving grids for the unsteady flow solver. The solutions of
the flow- field and the structural dynamics are coupled strongly in time domain by a fully implicit method. The
coupled CFD–CSD method simulates the aeroelastic system directly on the time domain to determine the stability of
the aeroelastic system. Based on the commercial solvers with availab.. View More»
