An Overview of the AG2 Project: Latest Achievements

This paper offers an overview of the Project of AIRGREEN2 (AG2, Clean Sky 2), in terms of main targets, technology development and maturation path, current achievements and further steps and perspective. Starting from the industrial and scientific scenario in which AG2 was conceived, outlining the specific way it meets the current market and environmental requirements, the general structure is illustrated, paying attention to the specific validation gates and demonstration test campaigns. The paper then continues with an overview of the last achievements, encompassing the ground tests of an adaptive winglet and of an innovative wingtip, the finalization of a wind tunnel campaign for aeroelastic validation and the realization of morphing device models, for the upcoming wind tunnel tests on a flexible and laminar wing model. Finally, the next steps of the research are introduced, with specific reference to the ground test of a multifunctional flap, the execution of the just mentioned wind tunnel demonstration on a laminar, flexible and morphing wing, and the final flight demonstration of the winglet and of the wingtip.
