“…Because the stiffness error consists of errors of both bending stiffness and torsional stiffness, the error calibration should modify these two parts at different levels. According to (4), the coupling stiffness factors can be obtained by specific composites lay-up design [14,15]. Adding composite layers of different thickness and different lay-up orientations on different positions of the skin component would satisfy lay-up design for error calibration.…”

The composite structure-similar flutter model (ComSSM) not only shows higher structural efficiency but also provides convenience for the purpose of fabrication in the aerodynamic flutter model. The manufacturing process of ComSSM is different from conventional composites structures. The geometry parameters and nongeometry parameters of ComSSM need to be controlled cooperatively and precisely to obtain higher product quality. A method of precise manufacturing is developed based on the error calibration of nongeometry parameters. The accuracy of structural performance of ComSSM is ensured by reducing the manufacturing stiffness, controlling the error of mechanical performance, and calibrating the error of modal frequency.
