Landing gear has complex structure and the maintenance of landing gear requires a lot of tooling equipment. Our company's technology for assembling and disassembling landing gear products is advanced in China.
Fluorescence penetration, magnetic particle detection, X-ray detection, eddy current and other detection methods are used to detect internal and external defects and ensure the safety of the landing gear. The relevant process specifications developed by our company for non-destructive testing are advanced in China.
The repaired landing gear is tested by special equipment to simulate various use cases to ensure product performance. There are less than 3 enterprises in China with the same testing capabilities.
The landing gear will inevitably be damaged during use, and its service life is extended through advanced repair technologies such as additive repair and supersonic flame spraying.
