| Abstract: |
| Against the background of frequent environmental failure of sealing products on helicopter serving in severe environment, environmental tests and evaluation technologies of aeronautical rubber sealing material and product were reviewed. Current research status of natural environmental test technologies including atmospheric exposure test and outdoor natural acceleration test of aeronautical rubber sealing material and product were analyzed. Theories and methods of simulation acceleration test technology in laboratory including hot air aging, UV aging, ozone aging, damp heat, low temperature, salt spray, fungus and combined environmental test were introduced. Based on these, two research fields including multi simulation acceleration test technology of rubber sealing products in laboratory and environmental effect data accumulation and applications of sealing components should be emphasized in future researches. |
