Nature, smart structures, and morphing UAVs
Daniel Inman, Univ. of Michigan (United States)
Nature through careful observation and tests of gliding avian species have resulted in new thoughts how to design morphing uncrewed air vehicles (UAV) and what morphing motions might make for better performance. An understanding of avian flight stability suggests a new approach to morphing aircraft design. Of interest is how to create these motions using smart materials to replicate avian abilities. Coupled with new learning algorithms, methods for designing smart autonomous morphing air foils for use in small UAVs are presented. Modifications of reinforcement learning (RL) techniques are used to teach a smart morphing wing to respond to gusts, following the inspiration of gliding gulls who respond immediately and autonomously to unknown changes in flow to maintain stability and control in unpredictable environments. We strive to translate this knowledge to flight control of UAVs. Last, a way forward is suggested to create a new class of structures: autonomous multifunctional structures. An outline of what is needed in terms of future research is presented.
Daniel J. Inman is the Harm Buning Collegiate Professor and former Chair of the Department of Aerospace Engineering at the University of Michigan. Since, 1980, he has published eight books, 20 book chapters, over 410 journal papers and 674 proceedings papers, given 78 keynote or plenary lectures, graduated 69 Ph.D. students and 75 MS degrees. He works in applying smart structures to solve aerospace engineering problems including energy harvesting, structural health monitoring, vibration suppression and morphing aircraft. He is a Fellow of AIAA, ASME, IIAV, SEM and AAM. He is the Editor-In-Chief of the Journal of Intelligent Material Systems and Structures.

In-line quality assurance for ENDT of multi material adherend surfaces
Christian Tornow, Fraunhofer Institute for Manufacturing Technology and Advanced Materials, IFAM (Germany)
Global demand to reduce CO2-emissions will continue to increase drastically. To reduce CO2-emissions lightweight structures needs to be implemented in all transport applications. Together with that, low-weight and high performance materials must provide safety and reliability, at economical prices. Extended Non-Destructive Testing (ENDT) contributes to safeguarding the performance of adhesively joined load-critical structures, permitting to steadily monitor adherent surfaces prior to bonding and to detect adhesion properties of bonded components.
In the present work, approaches exceeding the state-of-the-art of innovative ENDT techniques like robot-based Laser-Induced Breakdown Spectroscopy (LIBS) are presented. Furthermore, automated, AI-based image processing and evaluation methods for surface quality inspection are shown, aiming to overcoming today’s limitations concerning handling, evaluation speed and reliability of results. We show first results when applying automated in-line surface quality assurance approaches for assessing multi material adherent surfaces.
Christian Tornow has a diploma in Engineering Physics from the University of Applied Sciences in Emden, Germany (2004) and is a DVS®-EWF-European Adhesive Engineer (2017). He has been a scientist at Fraunhofer Institute for Manufacturing Technology and Advanced Materials, IFAM since 2004 and is the co-founder and deputy head of the "Quality Assurance and Cyber-Physical Systems" department. His fields of research include adhesive bonding, surface analysis, wettability of surfaces, and in-line quality assurance methods. He has been a lecturer in DVS-EWF-Adhesive Engineer courses in the field of quality assurance, surface analysis, wettability (adult education) since 2013 and a lecturer in Composite Engineer courses in the field of quality assurance and surface analysis (adult education) since 2014. From 2010 to 2014 he worked on the EU funded project ENCOMB and from 2015 to 2018 worked on the EU funded project ComBoNDT. He has participated in numerous national and international projects with partners from aeronautics, space, automotive and transportation sectors in the field of in-line quality assurance and extended non-destructive testing.
