Realization of a Shapevariable Fowler Flap for Transport Aircraft

This paper presents a part of the major R&D project “Adaptive Wing (ADIF)” of the partners German Aerospace Center (DLR), DaimlerChrysler Research, and Daimler-Chrysler Aerospace Airbus. Using as an example the Airbus A330/340 fowler flap, the objective of this project is to show, how the high lift behavior of modern transport aircraft can be improved by intelligent structural concepts, without negative effects on cruise flight. Even an improvement in transonic flight is possible. To reach this aim, a combination of passive and active measures is necessary, as the following paper shows.
