Evolution of corrosion of civil aircraft based on improved grey models

Structure corrosion is one of the most common damages affecting the structural integrity of the aging civil aircraft. Three grey models were applied for predicting the corrosion evolution during aircraft maintenance checks. The developed models include the basic GM (1, 1) model and two improved models with the initial condition optimized by linear transformation and partial differential methods, respectively. Both improved models show better quantitative agreement with the existing data, while the model using the partial differential method exhibits the highest prediction accuracy amongst the three models presented above. Such models can also be used on the structure of other complex equipment to improve the efficiency of preventive maintenance.
