Using bydroforming process the forming of aircraft large complex double curvature covering parts was completed. The process parameters through analyzing the forming process and numerical simulation were obtained. The simulation results by experiments were verified. Two kinds of typical defects in the forming process were analysed. Finally the part with qualified requirements was formed.
