An efficient approximate POD/ROM reconstruction method was proposed that can use the existing CFD-based POD/ROMs to rapidly obtain the new aeroelastic responses when structural parameters of the transonic aeroelastic system are changed at global level. The approximate method is illustrated and verified by the AGARD 445.6 wing model with different structural parameter variation. The simulation results show that proposed new POD/ROM reconstruction method can accurately capture the new aeroelastic responses and flutter boundary corresponding to the changed system with high efficiency. The proposed method extend the traditional POD/ROM from fix structural aeroelastic system to those with large global structural variations.
