Adaptive wing: Investigations of passive wing technologies for loads reduction in the cleansky smart fixed wing aircraft (SFWA) project

In the work package “Adaptive Wing” in the Clean-Sky “Smart Fixed Wing Aircraft” (SFWA) project, design processes and solutions for aircraft wings have been created, giving optimal response with respect to loads, comfort and performance by the introduction of passive and active concepts. Central activity of the work was the design and optimization of adaptive wing structures, for complete wings as well as for special components. This process, often called "aeroelastic tailoring", formed the backbone of the work package. Other important contributions have encompassed the development and improve-ment of methods for loads analysis, by extending the classical linear tool set by fast non-linear approach-es. Partners from industry and research involved in the work package contribute with special expertise to the process.
The paper gives an outline of the objectives and the work done in the work package, as well as an over-view of the integration of the “Adaptive Wing” activi-ties in the framework of the SFWA project.
