Depending on their structural and aerodynamic design joined wing configuration can display complex aeroelastic modes of behavior and present a considerable design challenge. The current paper presents a review of past work in the area of joined wing aeroelasticity, offers an intuitive/qualitative discussion of their dynamic behavior, surveys a number of possibly relevant problems from aeroelasticity, structural dynamics, and applied mechanics, and discusses analysis, testing, and optimization challenges involved. It is believed that the joined wing analysis and design problem cuts across traditional disciplinary lines, and makes it necessary to address it through significant collaboration among researchers in related areas and through integrated multidisciplinary studies. It is hoped that the present paper will stimulate research and collaboration that will lead to significant progress in the understanding of this dynamically rich and potentially important unusual configuration.
