Abstract
Different aeroelastic problems require different levels of fidelity, for transonic aeroelasticity calculations we apply eigenvalue stability analysis to large dimension aeroelastic models, that arise from the exploiting CFD. The efficiency of this method allows for several non-deterministic analysis to be carried out through the use of an approximate Newton solver, including flutter uncertainty quantification due to structural variability and data assimilation.
To predict the aeroelastic effects in nonlinear structures, an Harmonic Balance method was developed to compute Limit Cycle Oscillations. As with the eigenvalue formulation, the efficiency of the HB method permits the practical use of non-deterministic techniques, which are exploited to assess the impact of uncertainty in the development of LCO on aircraft structures.
