Kurzfassung
This research presents the conceptual and preliminary design process of the TU-Flex wing. This vehicle has been designed as a subscale-flying aeroelastic demonstrator with a transport aircraft configuration. The most flexible version of this vehicle should show a coupling between structural and rigid body dynamics during operation. In this paper, the reference wing for this aircraft was designed, such that a given level of structural flexibility and generally lower modal frequencies could be reached. Design boundary conditions included flexibility, operational, sensor, facility, and environmental requirements. The design flow allowed flexibility to evaluate multiple structural configurations, airfoils, materials, and load cases. A trend study was completed on a conventional wing-box design and a load-carrying closed skin shell. The selected wing is capable of displaying deformations above 10% for the 2g flight condition while meeting our construction feasibility requirements. The selected wing will proceed to the detailed design phase and subsequently to the construction process.
