Rotational-Stiffness Sensitivity of a Low-Frequency Aeroelastic Branch in a Wingtip-Connected Modular UAV
This study examines how the rotational stiffness of two wingtip interfaces changes the low-frequency aeroelastic response of a free–free, three-module unmanned aerial vehicle. A finite-element model coupled with doublet-lattice aerodynamics is analyzed using the p–k method. The response associated with the lowest retai...
