Unsteady Lifting-Line Free-Wake Aerodynamic Modeling for Morphing Wings

open access: yesAerospace
A time-stepping, lifting-line solution algorithm for the prediction of the unsteady aerodynamics of morphing wings is presented. The velocity induced by the wake vorticity is determined through a free-wake vortex-lattice model, whereas the Küssner and ...

Assessment of the Fatigue Behavior of Wings with Distributed Propulsion

open access: yesEngineering Proceedings
The integration of distributed electric propulsion into a wing significantly alters the dynamic behavior of the wing. Consequently, the loads on the wing structure in service, in particular upon transient gust and landing impact loads, change ...
