The Aeroservoelasticity of High Aspect Ratio Wings with Many Control Surfaces – Recent Progress

Longer and thinner wings, optimized for weight and aerodynamic performance, would benefit significantly from, if not rely on, active control technology for maneuver load control and gust loads alleviation, as well as modal damping augmentation or flutter suppression. The talk will survey parallel efforts in Europe and the US in this area that have been built on university, industry, and national research lab partnerships and that have been focused on wind tunnel experimental work, leading to advances in math modeling, simulation, control, and design insights. Thoughts on the role of the research university in the development of aeroelastic / aeroservoelastic technology will also be shared.

Eli Livne is the Boeing Professor of Aeronautics and Astronautics at the William E. Boeing Department of Aeronautics and Astronautics at the University of Washington in Seattle, USA. His years of experience include analysis, design, and test work on various civil and military aircraft as well as teaching and research in the areas of aeroelasticity, aeroservoelasticity, multidisciplinary design optimization (MDO) of aeronautical systems, applied aerodynamics, and aircraft design.

Professor Livne was the Editor in Chief of the AIAA’s Journal of Aircraft from 2011 to 2022. He is the recipient of the AIAA’s Holt Ashley Award for Aeroelasticity as well as the International Council for the Aeronautical Sciences (ICAS) Award for Innovation in Aeronautics “for seminal contributions to the theory and practice of Aeroservoelasticity in the context of aircraft Multidisciplinary Design Optimization, and pioneering work towards the maturation of aircraft active flutter suppression technology.” He is a Fellow of the AIAA.
