Cover Story: With the increased use of composites in aircraft, many advancements in the field of structural health monitoring (SHM) have been achieved, yet its application is still not often seen in operational conditions, mostly due to a gap between research and application, which constrains the shift toward improved aircraft maintenance strategies such as condition-based maintenance (CBM). This study discusses how data fusion concepts can aid in the maturing of the SHM field for composite aircraft structures and formulates its benefits, opportunities, and challenges. For demonstration purposes, a conceptual design study is included for a representative aircraft wing structure, showing how data fusion concepts can be of benefit in moving towards operational CBM applications in the aircraft industry.
