| Abstract: |
| Based on fault results of the Electrical Wiring Interconnection System (EWIS) and the South China Sea environ-mental exposure test results of the aircraft's typical Electrical Wiring Interconnection System (EWIS), the corrosion failure law, corrosion types and causes, and electrical performance variation law of EWIS in marine environment were studied. The results show that the failure modes of EWIS corrosion in marine environment were various, which can easily lead to frequent intermittent faults and decrease of electrical performance and shielding effectiveness. From the point of view of seaworthiness, it is proposed to improve the marine environmental adaptability of EWIS from material selection, design, operation and maintenance, and analysis and utilization of fault data. |
