High-precision CFD/CSD coupling aeroelastic load analysis is an effective way to solve the nonlinear aeroelastic problem of flexible wings. In order to improve calculation
efficiency while ensuring calculation accuracy, a nonlinear static aeroelastic load analysis method accelerated by vortex lattice method is proposed in this article. Vortex lattice method is adopted to achieve a faster convergence both in the iteration of static aeroelastic analysis and trimming process. An RBF-based mesh deformation tool with greedy algorithm is used to realize fast and accurate mesh deformation during the iterations. The numerical model of a commercial aircraft with very flexible wing is investigated by the traditional aeroelastic load analysis method and the accelerated method. Compared with the traditional method. The proposed accelerated method can significantly improve the calculation efficiency while ensuring the high precision.
