Integrated modeling of motion decoupling and flexure deformation of carrier in transfer alignment

•This paper established the integrated transfer alignment model of decoupled and flexed deformation.•Combined with FBGs to measure the deflection of the aircraft wing, a general deflection model of the aircraft wing is established, and the accuracy of the model is verified by finite element analysis.•The coupling is solved, and the system error equation is updated. The feasibility and accuracy of the proposed transfer alignment model are verified by semi physical simulation experiments.
