Abstract


Morphing of selected aircraft parts is a promising component technology to augment aircraft efficiency, and future aircraft designers will likely make increased use of adaptive structures, introducing Active Compliant Systems (ACS) e.g. to entire wing sections. Consequently, options for better control and monitoring of ACS must also be explored. In this paper, we assess the potential for multi-functionality between a winginstalled Structural Health Monitoring (SHM) system and an ACS used to shape-adapt the top part of a non-planar C-wing. We suggest a possible combination of SHM technologies that distinguishes between the desired adaptive response of the morphing system, aeroelastic loads and material fatigue. Over time, a coupled SHM-ACS system may even be capable of learning how to perform flight maneuvers most efficiently, that is, with minimum strain incurred in the material.
