Abstract

A static aeroelasticity analysis is carried out for AGARD-B wind tunnel calibration model. RANS solution obtained by the pointwise relaxation implicit discontinuous Galerkin CFD solver is fed into structural analysis using NX Nastran to iteratively determine aerodynamic equilibrium configuration of the wind tunnel model. The effect of model deformation on aerodynamic characteristics is examined. It is shown that an aerodynamic equilibrium configuration is obtained with three iterations for typical supersonic flow conditions. The computed displacement at the wing tip is found to be less than 1 mm. However, the aerodynamic coefficients are shown to be altered with this small deformation.
