Abstract: “Aeroengine Structure” is a core course for undergraduate students majoring in maintenance engineering. This course helps students understand aeroengine from a macro perspective, master the basic structure of aviation gas turbine engine, understand how major component systems work, work characteristics, and structural disassembly, so as to lay a necessary theoretical foundation for students to engage in civil aviation maintenance engineering in the future. Aiming at the problems of complicated, abstract and difficult to understand in the existing teaching process, this paper adopts the complementary multi teaching method based on diversified technology, which combines "online and offline" and "virtual and reality", to realize the process assessment, so as to provide better support for students to learn at any time and anywhere, enable students to master the relevant knowledge of aeroengine structure faster.
