The 3 D scanning and reverse design technology has the characteristics of advanced technology,high precision and efficiency. In recent years, it has been more and more widely used in the field of industrial manufacturing. Therefore, the application of three-dimensional scanning and reverse design technology to the design, manufacturing and machining quality inspection of airplane impeller has become a current research hotspot. Through the application of the new win3 D-M scanning system three-dimensional scanner and related design software, the reverse design, surface reconstruction and improvement of the impeller have been carried out in the text, which widens the application scope of three-dimensional scanning and reverse design technology, and provides reference for the development of the impeller. By comparing with the traditional theoretical research and experimental research, the application of reverse engineering to design impeller can shorten the design cycle and reduce the design cost;the three-dimensional geometric model provides a certain reference for the subsequent research, improvement and optimization of impeller structure and subsequent cam machining. At the same time, this method can be used in the teaching of related majors in universities to improve students’ innovative design ability and stimulate students’ enthusiasm for large aircraft manufacturing.
