The goal of this internship is to support a project that the NRC has undertaken upon the request of the Department of National Defence to improve the understanding of bonded composite joints specimens and to evaluate the capabilities of existing Structural Health Monitoring (SHM) technologies as they apply to the CH-149 helicopters or other aging aircraft. To achieve this, a literature review will be carried out. A plan for further testing, analysis and modelling will be developed with the intention of filling the gaps in public knowledge discovered during the literature review. Some preliminary non-destructive evaluations (NDE) techniques may be utilized to determine the technologies effectiveness. Using the intern's research, NRC will be able to make recommendations regarding technologies that could potentially be used on commercial and military aircraft to increase aircraft reliability and therefore safety and efficiency.
