Summary:

The target of this paper is to describe the SHM project developed at CIRA. In order to achieve the low weigh target in the MALE UAV structures, the SHM project has the target to setup a system that, being able to evaluate the current state of the structure, will enable minus conservative assumption in the composite structural design. A lamb wave based procedure has been developed in order to analyze the presence of a barely visible impact defect (BVID). The techniques for the damage detections of composite and metallic structures have been developed through extensive numerical-experimental analysis based on lambwave investigation by using piezoelectric sense- actuators. The use of SHM technology and methodology has shown the possibility to have a significant reduction in the structural weight. The technology has achieved a TRL level between 4 and 5 and in order to achieve a higher TRL a test on a component in relevant environment is planned at the end of 2014. The application on MALE UAV prototype will be done also considering the STANAG 4671 (USAR) NATO airworthiness regulation
