This paper proposes a data management system for Finite Element Analysis (FEA) of full-scale aircraft structure, which includes the management modules of FEA models, computation, results and parametric operation. Based on strict and standardized administration of FEA models and analysis results, not only human errors on data processing will be reduced, but also the efficiency of FEA for airframe structures will be improved. Furthermore, the capability of aircraft structural strength design will be enhanced as well.
