Abstract: According to the overall requirements of the Mechanics “101 Plan”, this article discusses the design and practice for the core practices - aeronautical practical projects. Focusing on our university's “Chief Engineer Cultivation Culture” and starting from the cultivation of the characteristics of a “chief engineer” with “specialized expertise, strong systematic perspective, emphasis on practice, and capable of taking responsibility”, the objectives for aeronautical practical projects are established according to the current development status and trends in the aeronautical field. 10 practical projects covering aerodynamics, solid mechanics, and aeroelastics have been designed at three levels of basic projects, advanced projects and cutting-edge projects. Taking aircraft vibration theory teaching practice as an example, we introduce the specific implementation of aeronautical practical projects in our school's mechanics course teaching.
