National Standard of the People's Republic of China GB/T 13652—2023 Aircraft Tire Surface Quality
Standard Development Background and Technology Evolution Analysis
GB/T 13652 "Aircraft Tire Surface Quality" has undergone two revisions since its first release in 1992. This revision replaced the 2004 version of the standard in 2023, mainly proposing more stringent and detailed technical requirements for the surface quality of aircraft tires. With the advancement of aviation technology and the improvement of tire performance requirements, the new standard has been comprehensively optimized in terms of safety, reliability and durability.
Comparison of main technical changes
Serial number Requirements of the old standard Requirements of the new standard 1 Crown rubber edge thickness requirement ≤1.0mm (≤200 mm section width) Adjusted to ≤2.0mm (＞200 mm section width) 2 Mold mouth misalignment value ≤0.5mm (≤600 mm outer diameter) Adjusted to ≤1.0mm (＞600 mm outer diameter) 3 No requirements for pattern glue deficiency Newly added pattern glue deficiency depth ≤1.5mm (＞200 mm section width) Interpretation of aircraft tire surface quality requirements
Analysis of key issues and practical application cases
- Crown rubber edge: For tires with a nominal section width of ≤200mm, the qualified product standard requires the base thickness of the rubber edge to be ≤1.0mm. In actual production, care should be taken to avoid the problem of excessive thickness of the rubber edge caused by improper mold design.
- Mold mouth misalignment: Applicable to the case where the nominal outer diameter of the tire is ≤600mm, and the misalignment value is controlled within ≤0.5mm. It is recommended to use high-precision processing equipment and advanced vulcanization technology to ensure dimensional consistency.
Comparison of technical requirements table
Serial number Surface quality problem Qualified product standard Repairable standard 1 Crown rubber edge Section width ≤200mm: Thickness ≤1.0mm Not repairable 2 Mold misalignment Outer diameter ≤600mm: misalignment value ≤0.5mm Not repairable 3 Lack of rubber in the pattern Section width ≤200mm: depth ≤1.0mm; >200mm: cumulative length does not exceed 1/5 of the circumference Repairing is allowed, polishing is smooth Implementation suggestions for aircraft tire surface quality
Several aspects that enterprises should focus on
- Raw material procurement: Select high-performance rubber materials to ensure the uniformity and consistency of the rubber.
- Mold maintenance: Regularly check and maintain tire molds to prevent surface quality problems caused by mold aging.
- Production process optimization: Use advanced vulcanization technology and temperature control technology to ensure uniform tire structure.
- Quality Inspection: Establish a complete inspection system and equip with high-precision measuring equipment to ensure that each indicator meets the standard requirements.
- Employee Training: Strengthen technical training for quality inspectors and improve their defect identification and handling capabilities.
Future Technology Development Trends
With the continuous development of the aviation industry, future tire surface quality standards will pay more attention to the application of intelligent detection and automated repair technologies. For example, computer vision technology is used to quickly identify tread defects, and nanomaterial modification technology is used to improve rubber performance.
Summary
The release of GB/T 13652—2023 "Aircraft Tire Surface Quality" marks a further improvement in my country's aviation tire manufacturing technology. By strictly controlling surface quality issues, companies can significantly improve the safety and reliability of tires and meet the needs of modern aircraft for high-performance tires.
