Paper Abstract

The following paper presents the development of an adaptive aeronautical structure at the example of a high lift device, a so-called fowler flap. It shows the passive optimization of the flap with a complex finite element model and illustrates the necessity to develop an active structure, due to the limited possibilities to increase the efficiency of the passive flap. Different kinds of active measures are discussed and it is shown, why an activation of the structure with shape memory alloy (SMA) actuators is preferred. Additionally, the results and findings of experiments with an active spar that was developed, built, and tested at the Institute of Structural Mechanics (ISM) at the German Aerospace Center in Braunschweig are presented.
