Wind tunnel testing is a reliable means for R&D aerial vehicles of aerospace, e.g. aircraft, missiles, rockets etc. The wind tunnel models are the objects used in the tests, and stiffness-similar models are important for the structural and aerodynamic design of aerospace vehicles. The accuracy and economy of the model design and fabrication have a significant impact on the quality and cycle of vehicle R&D. The review will first give an overview introduction of the wind tunnel models with stiffness-similarity, and then detail design procedure and fabrication processing, which are developed by the author’s group based on 3D printing. The review can provide new methods to design and fabricate stiffness-similar models for wind tunnel tests for designers and researchers concerning the structural and aerodynamic studies in the aerospace industry.
