Title: Transonic Flutter Computations for a 2D Supercritical Wing
Authors: S. Weber, K.D. Jones, J.A. Ekaterinaris and M.F. Platzer
Abstract:
A numerical investigation of the transonic two-degree-of-freedom
bending/torsion flutter characteristics of
the NLR 7301 section is presented using a time domain method.
An unsteady, two-dimensional, compressible, thin-layer Navier-Stokes
flow-solver is coupled with a two-degree-of-freedom structural model.
Furthermore, the Baldwin-Lomax, the Baldwin-Barth and the
Spalart-Allmaras turbulence models are implemented, each in
conjunction with the transition model of Gostelow et al. The
transition onset location can either be predicted with Michel's
criterion or specified as an input parameter. Computations of the
steady transonic aerodynamic characteristics show good agreement
with the experimental results using the Baldwin-Barth or the
Spalart-Allmaras model in combination with transition modeling. The
aeroelastic computations predict limit-cycle flutter in agreement
with the experiment. However, the computed flutter amplitudes are an
order of magnitude larger than the measured ones.
