Abstract:
his paper deals with advanced structural health monitoring technologies and their aplications in aircraft structures. Structural Health Monitoring (SHM) is an innovative way of on-board Non-Destructive Testing (NDT) to directly assess the integrity of aircraft structures. The principle of SHM is comparable to the human nervous system. Discrit sensors which form a network remain permanently mounted onto, or embedded into the aircraft structure, detect and diagnose inevitable structural damage, mechanical loads or abnormal conditions. The sensors are interrogated via an on-board or off-board diagnostic system and information on the structural state is reported to maintenance team. Special attention is also given to NDT in aircraft manufacturing. It is a quality step used at key stages to establish whether the component is fit to advance to the next manufacturing operation.
