Abstract:

This paper presents a part of the major project Adaptive Wing ADIF of the partners German Aerospace Center DLR, DaimlerChrysler Research, and DaimberChrysler Aerospace Airbus. Using the Airbus A330340 fowlerflap as an example, 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. For this, a combination of passive and active measures is necessary, as the following paper shows.
