Research on the Influence of Tension and Compressive Fatigue Load on the Corrosion Coefficient of Parking on the Ground

Abstract:

To ascertain the grounding corrosion coefficient parking on the ground is the key to evaluate the airframe calendar life. The influence of pull and press load on the grounding corrosion coefficient was evaluated in this paper. The main results are as follows. First, the fatigue life always follows the logarithmic normal distribution after pre-corrosion for pull fatigue loading and press fatigue loading. But the scatter of fatigue life for the wing down-panels is reduced with the fatigue life, and the scatter of fatigue life for the wing up-panels is not changed. The second, the coefficient of the wing up-panels test sample is not changed with the increase of the corrosion calendar life. But, the coefficient of the wing down-panels test sample descends with the increase of the corrosion calendar life.
