    Abstract
  • A method for supervising the service life of aircraft structures under corrosive environment was developed. Based on the evaluation results of fatigue life at room temperature and in the air and the expected calendar life index, considering the influence of pre-corrosion under ground environment and the corrosion fatigue during flight, an objective function was established to supervise the inspection threshold, overhaul intervals and total life. Fatigue life supervision and calendar life supervision were unified by this function. In addition, significant corrosive environment change was considered. As an example, a practical supervising process was given to demonstrate the application of this method.
