Cover Story: The application of morphing wing devices can bring several benefits in terms of aircraft performance. Within the framework of AirGreen 2, a European research project running along the CleanSky2 platform, a safety-driven design of an adaptive winglet was created through the examination of potential hazards resulting from operational faults, such as actuation jamming or structural failures. The main goal was to verify whether the morphing winglet systems could comply with the standards of civil flight safety regulations (EASA CS-25) and airworthiness requirements, especially from an aeroelastic stability standpoint. Fault trees were finally developed to assess the compliance of the system to the quantitative safety requirements deriving from the fault and hazard analyses (FHAs). View this paper.

One of the main limitations of linearity assumptions in airfoil’s aero-elastic problems is the inability to predict the system behavior after starting the instability. In reality, nonlinearities may prevent the amplitudes from going to infinity...
