Abstract：Because of the extreme and complex working environment, the aviation industry has very strict requirements for the processing quality and accuracy of material. Compared to traditional manufacturing technology, laser processing technology has the characteristics of small heat-affected zone, high efficiency and easy automation, therefore it has broad application prospects in the field of aeronautical manufacturing. Combining with the characteristics of aviation industry, the applications of laser cladding, drilling, cleaning and processing functional surface structures have been reviewed in the study. The mechanisms of laser processing have been clarified, and the roles of laser processing on improving surface properties and processing quality have been analyzed. Finally, we summarized and prospected the outlet of laser processing in the field of aviation.
