Abstract

A static aeroelasticity analysis is carried out for the AGARD-B wind tunnel model. The Reynolds averaged Navier-Stokes (RANS) solution obtained by the cell-wise relaxation implicit discontinuous Galerkin computational fluid dynamics (CFD) solver is fed into the structural analysis method to iteratively determine the aerodynamic equilibrium configuration of the wind tunnel model. The effect of model deformation on the aerodynamic characteristics is examined. It is shown that an aerodynamic equilibrium configuration can be obtained within several iterations for typical supersonic flow conditions. The displacement computed at the wing tip was found to be less than 1mm for the AGARD-B model. However, the aerodynamic coefficients are shown to be altered with this small deformation.
