Currently, all civil aircraft in my country use products from foreign companies:
1.The domestic regional aircraft ARJ21 uses American Goodyear tires
2.The domestic large aircraft C919 uses French Michelin tires

Civil aircraft tires are consumables, low in price and short in life:
1.The service life of each tire is about 250 takeoffs and landings
2.Civil aircraft tires are restricted, and civil aircraft will be grounded in 3 months
3.Asymmetric sanctions from other countries will bring huge losses

The independent control of high-end civil aviation tire technology is imperative.

Chinese Academy of Sciences C-type pilot project:
1.Chinese Academy of Sciences has deployed C-type pilot projects to address the “bottleneck” problem of aviation tires;
2.Effectively gather the advantages of domestic universities, research institutes, enterprises, etc. in tire materials, design software, manufacturing, application evaluation, etc. R&D strength.

1. The large-scale flight take-off and landing dynamics device was built in Huangpu:
The first large-scale flight take-off and landing dynamics device in China; A large-scale scientific research test platform for comprehensive performance evaluation and verification of air-driving tires.
2. The national and local governments strongly support:
Funds are used to master independent high-end civil aviation tire technology; Make up for the shortcomings of aviation tire materials, manufacturing technology and processes; and achieve overtaking of foreign technologies.

1.Relying on the discipline foundation, talent pool, applied research and engineering technology advantages of Huangpu Materials Institute in Guangdong, Hong Kong and Macao Greater Bay Area in rubber synthesis and digital tire design;
2.The research and development of aviation tires for C919/A320 and other models has been carried out to solve the problems of dependence on imports, backward tire structure and poor wear resistance;
3.The construction of civil aviation tire production base and airworthiness certification will be completed in 2025;
The application of aviation tires of multiple specifications on civil aircraft can meet the development needs of future aircraft.
