| Abstract: |
| Objective To study the correlation between surface airborne environmental tests in the South China Sea and laboratory environmental tests for five types of typical aircraft. Method The outdoor exposure tests of five types of typical aircraft surface substrates and coatings were conducted in South China Sea environment for three years. At the same time, solar radiation-damp heat-salt spray combination tests were conducted in the laboratory. The correlation between the two test environments was examined by testing appearance, gloss, and chromatic aberration. Results The rank correlation coefficients obtained from the basis of the loss of light, color difference, and aging rating were averaged, and the average rank correlation coefficient was calculated to be 0.96, indicating that the test laboratory accelerated test and the natural exposure test of the coated sample were extremely strongly correlated. Conclusion The correlation of the surface coating in the South China Sea atmospheric environment test and the laboratory environmental test is proved by the rank correlation coefficient method. It provides a basis for the follow-up treatment of the South China Sea environmental test. |
