Based on the theory of combustion chamber design, material selection, parts forming, welding and post-processing, the basic forming and manufacturing methods such as stamping, welding, cutting and heat treatment are known through hands-on practice. Practical projects focus on integrating theory with practice, emphasizing the process of knowledge acquisition, comprehensive application of knowledge and innovative ability, and deepening students’ systematic cognition of the manufacturing process of general welding products. Through team cooperation labor practice, cultivate engineering literacy（including labor literacy）, engineering practice ability and innovative spirit. At the same time, by making jet engines by themselves, students are encouraged and guided to have enthusiasm for aviation, so as to improve the effect of practical teaching. 燃烧室 实践教学 焊接加工 工程能力 combustion chamber practical teaching welding processing engineering ability TG44-4;G712 2022-03-08 9 51
