Outline
The aircraft landing gear endures complex loads and harsh service environments over extended periods， making it susceptible to various forms of damage. Remanufacturing technology provides an efficient means of repairing such damage and restoring performance， playing a vital role in ensuring flight safety. Focusing on the enhancement of overall performance， the design of both structure and materials has undergone continuous iterations and optimization. Traditional fixed landing gear gradually evolves into lightweight， high-strength retractable systems， while material design philosophies shift from static strength-based approaches toward multi-objective optimization that simultaneously considers damage tolerance， fatigue life， and maintainability. This paper reviews the types， materials， structural composition， typical damage mechanisms， and remanufacturing technologies of aircraft landing gear， emphasizes the typical failure modes and damage mechanisms encountered during service， and systematically summarizes key technological aspects of the remanufacturing process， including precise non-destructive testing and damage assessment， high-energy beam repair and surface strengthening techniques， as well as dimensional restoration and precision assembly repair processes. Furthermore， it highlights future trends such as the application of advanced high-performance materials， intelligent manufacturing technologies， and green remanufacturing processes. This review provides theoretical foundations and technical references for the engineering application and systematic development of aircraft landing gear remanufacturing technologies.
