Aero-engine model design and assembly practice teaching based on 3D printing

An effective mode is found for student hands-on activities, which are good ways for students to take an active part in after-class activities and strengthen their abilities. Through this kind of mode, the students learn practical skills and enhance their scientific research ability while consolidating their professional knowledge. It has long been a problem that college students have theoretical knowledge but lack practical experience. Our activity creates a brand-new way for students, including freshmen, to gain exposure to aeroengines. In the activity, students learn independently about relevant aviation design software and make their own aeroengine model in person, from preliminary learning to a clear and thorough understanding of the structure of a real aircraft engine. Then the students experience redesign, assembly, and production until a real model is completed, which can be used for hands-on practice for freshmen. This paper discusses the deep participation of students and the details of how the students designed and manufactured an aeroengine assembly model from scratch through teamwork, the profound effect on students themselves, and the experience with aeronautical learning and education. Additionally, the same mode can be applied to other teaching practices, providing students an opportunity to gain exposure to a real object, making it easier to master knowledge through active self-learning.
