Research progress in airworthiness conformity verification method and technology of civil aircraft materials

The airworthiness development status of civil aircraft in China was taken as the starting point of review. The airworthiness alternative methods of compliance method of the materials used in civil aircraft products were sorted out, and the relevant provisions requirements of materials used in civil aircraft products such as civil aircraft, engines and helicopters in China's civil airworthiness regulations were analysed. In the process of materials airworthiness conformity verification, the establishment of standards (specifications) based on statistical analysis is the core of material conformity verification. MOC1, MOC2, MOC4 methods are mainly used to verify airworthiness conformity of materials approved with the model. Facing the future, the application of materials with independent intellectual property rights, the construction of materials independent verification technology and capacity are the key to realize the industrialization development of advanced civil aircraft.
