Active and Passive Structural Measure for Aedrolastic Winglet

Abstract

This paper concerns the aero-structural design of winglets for transport aircrafts. The different multidisciplinary design targets are discussed and limitations of the conventionally aerodynamics-focused design approach are shown. In order to better combine conflictive targets the design space is opened towards advanced passive and active structural concepts. As basis, the suitability of different state-of-the-art numerical measures is evaluated and tools engineered for the efficient investigation of unconventional structures are presented.
