Architecture Design Method for Structural Health Monitoring System (SHM) of Civil Aircraft

The application of Structural Health Monitoring (SHM) technology will bring revolutionary changes in maintenance strategy of civil aircraft composite structure from scheduled maintenance to Condition-Based Maintenance (CBM) which means the maintenance job will be applied based on the real time conditions of aircraft structure. Its application would promote the operational safety and maintenance efficiency of the aircrafts. This paper briefly discusses the application requirements of SHM system, the main damage monitoring parameters list and applicative sensors for civil aircraft structures made from metal and composite materials. At last the overall architecture and function constitutions of SHM system are given.
