This session will present intermediate results from the Clean Aviation Ultra-Performance Wing project. Sustainable aviation is a major challenge that requires technology developments in many different areas. One of the key enablers for improving aircraft efficiency and therefore reducing green-house gas is drag reduction by an increased wing aspect ratio. The UP Wing project will validate, down select, mature and demonstrate key technologies and provide the architectural integration of high aspect ratio wing concepts for targeted Short/Medium Range aircraft (SMR). The multidisciplinary approach includes disciplines like aerodynamics, aeroelastics, structural and systems design, overall aircraft integration, associated computational methods and design tools and testing. The session will invite papers on the design, modelling, analysis, testing, validation, manufacturing and assembly of all the relevant technologies that are involved in the development of these advanced high-aspect ratio wings.
