Variable geometry wing-tip devices are considered to be a technology with high potential to improve aircraft performance. However induced drag reduction benefits suffer from penalties on aircraft level like increased wetted area, additional weight or power consumption. For the development of morphing technologies, the capability of a net-benefit assessment on aircraft level considering multiple flight performance optimization objectives within a single aircraft mission is essential. The purpose of this paper is to present aircraft flight performance improvements due to morphing wing-tips for a broad range of applications. For this study, the impacts of geometry adaption of a morphing wing-tip is considered and compared to a conventional rigid wing-tip rather than alternative wing-tip devices. Parameter studies and mission performance simulations are performed for the assessment of the morphing wing-tip degrees of freedom twist, camber and cant angle. Furthermore, the application of a methodology for morphing net-benefit assessment on aircraft level, including various performance metrics is presented.
