Fatigue life evaluation and test verification for civil aircraft structure under corrosive environment

  • Rationality of the fatigue life evaluated method for civil aircraft structures under corrosive environment was validated by test for the chordwise joint parts of wings which were typical fatigue critical parts of civil aircraft structures. And the fatigue life of this part under corrosion was evaluated. The pre-corrosion curve was obtained by pre-corrosion and followed fatigue test in common environment on simulated specimens of this critical part. The corrosion-fatigue influence factor was obtained by corrosion-fatigue test on the same specimens. Pre-corrosion and corrosion-fatigue alternation tests were carried out on large-scale simulated specimens. And the synthetical correction factor of corrosion under typical using condition was obtained. The correction factor of the alternative test was also obtained by evaluated method. The comparison between the two results shows that the evaluated method is rational and validity. And the fatigue life evaluated result of the chordwise joint parts of wings under corrosion was given.
