Static aeroelastic analysis of very flexible wings coupled with distributed propellers
Xibei Gongye Daxue Xuebao, 2023 Distributed propellers are widely used as propulsion for high-aspect-ratio long-endurance UAVs, and their load and slipstream will change the structural and aerodynamic characteristics of the wing, making geometric nonlinear effects more prominent.

Online Model-Free Reinforcement Learning for the Automatic Control of a Flexible Wing Aircraft [PDF]
IET Control Theory & Applications, 2020 The control problem of the flexible wing aircraft is challenging due to the prevailing high non-linear deformations in the flexible wing system. This urged for new control mechanisms that are robust to the real-time variations in the wing's aerodynamics.

Multidisciplinary Design and Optimization of Variable Camber Wing with Non-Equal Chord
Aerospace, 2023 Since the taper ratio of most wings is not equal to 1, the beam-disk trailing edge deflection mechanism originally designed for the rectangular wing is not fully applicable to the non-equal chord wing.
