Failure Criterion‐Based Bead Optimization of a Wind Turbine Blade Root Section

Wind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This study presents a bead‐based optimization framework for fiber composite wind turbine blades, employing the Tsai–Wu failure criterion as the structural performance measure. The objective is to design an optimal transition geometry between an existing blade and a root section with 20% smaller diameter, while preserving the original material ...

Aerodynamic and aeroacoustic performance of airfoils with morphing structures [PDF]

Wind Energy, 2015
AbstractAerodynamic and aeroacoustic performance of airfoils fitted with morphing trailing edges are investigated using a coupled structure/fluid/noise model. The control of the flow over the surface of an airfoil using shape optimization techniques can significantly improve the load distribution along the chord and span lengths whilst minimising noise

Design of Intelligent Control Law Embedded With Dynamic Flow Field Perception Method for High‐Angle‐of‐Attack Maneuvers of Numerical Virtual Flight Agent

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
In numerical virtual flight (NVF) tasks, strong unsteady flow disturbances can change aerodynamic behavior and reduce the effectiveness of control surfaces, increase the difficulty of aerodynamics modeling and controlling at high‐angle‐of‐attack (high‐AoA).

Analysis of Energy Budget Characteristics of Three‐Segment Wings in Wind Gradient Dynamic Soaring

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
Wind gradient dynamic soaring enables bioinspired aerial vehicles to harvest environmental energy and extend endurance; yet quantitative comparisons remain scarce on how multisegment wing configurations translate, under identical control and wind field conditions, into differences in energy budget.
