Rapid repair technique of aircraft damage is the requirement of military operations and training. It's also an important support to ensure the mastery of the air in modern high-tech war. With the development of new structural materials, traditional aircraft damage repair techniques have failed to meet the demands, with their shortages being analyzed. For its unique superiority, laser technique for the damages repair of aircraft structure is summarized, such as laser cutting, laser welding, and laser cladding used for battle field damage, corrosion and wear, including the conception of functional gradient material. Alloy powder system, microstructure, micro hardness regularities of distribution, resistance to wear and fatigue behavior of laser cladding are investigated. The merits of laser cutting are explained, and a mobile laser material processing system is introduced. Meanwhile, the need for further research is also briefly discussed.
