The transonic aileron efficiency is a hotspot and difficulty in the field of static aeroelastic analysis. The computational fluid dynamics (CFD)/computational structural dynamics (CSD) interaction method can supply high-accuracy resolutions, but it still has problems of mesh deformation robustness and lack of verification. Aimed at the above issues, a new method of mesh deformation based on dummy grids and dummy deformation was developed, and for the problems of non-physical oscillation and non-uniformly convergence in the process of interaction, the lax iteration method and comprehensive residual criterions were used. Based on the methods, the transonic (
