# Unsteady lifting-line theory and the influence of wake vorticity on aerodynamic loads

@article{Bird2021UnsteadyLT, title={Unsteady lifting-line theory and the influence of wake vorticity on aerodynamic loads}, author={Hugh J. A. Bird and Kiran Ramesh}, journal={Theoretical and Computational Fluid Dynamics}, year={2021} }

Frequency-domain unsteady lifting-line theory (ULLT) provides a means by which the aerodynamics of oscillating wings may be studied at low computational cost without neglecting the interacting effects of aspect ratio and oscillation frequency. Renewed interest in the method has drawn attention to several uncertainties however. Firstly, to what extent is ULLT practically useful for rectangular wings, despite theoretical limitations? And secondly, to what extent is a complicated wake model needed…
