Abstract

The virtual determination of static aeroelastic deformations of NASA's Common Research Model at high speed flow conditions up to high angles of attack is described. Aeroelastic equilibrium conditions are computed using a fluid-structure interaction simulation approach based on high-fidelity numerical fluid dynamics and structural analysis methods. The correlation of numerical and experimental results under varying aerodynamic loads and model deformations is investigated. Particular interest was focused on the accurate prediction of aerodynamic loads in the nonlinear flow regime beyond the design point angle of attack. Wind tunnel test data were made available from a recent test campaign performed at the European Transonic Wind Tunnel in Cologne, Germany, as part of the research project ESWIRP (European Strategic Wind tunnels Improved Research Potential). A generally good agreement is found between FSI simulation results and experimental data. Although some deviations remain, all aerodynamic and aeroelastic phenomena were captured correctly.
