Abstract

Due to fuel efficiency, advanced aerodynamic and structural concern, more and more composite materials used in aircraft desgin. In composite structure aeroelastic tailoring process, an accurate and efficient method to evaluate the aeroelastic stability is very required. The traditional CFD-based POD/ROM has been shown its accuracy and efficiency for transonic aeroelastic analysis at fixed system. In aeroelastic tailoring process, in order to meet the requirements of aeroelastic performance, the parameters of the composite structure need to be modified repeatedly and the aerodynamic model have to be reconstructed. However, these reconstruction procedures take a considerable time, and greatly increasing the time cost of the aircraft design. To develop a more efficient composite structure aeroelastic tailoring method, starting with improving the efficiency of aeroelastic performance evaluation, this paper propose an approximate aeroelastic characteristics evaluation method based CFD-based POD/ROM by introducing the structural dynamic reanalysis method. The improved AGARD 445.6 composite wing was employed to verify the accuracy and efficiency of the proposed method. The results show that the proposed evaluation method can not only accurately predict the aeroelastic response of the structure, but also greatly improving the efficiency of transonic composite structure aeroelastic tailoring.
