Dynamic lift enhancement mechanism of dragonfly wing model by vortex-corrugation interaction

Dragonfly wings, with their unique corrugated structure, may achieve superior aerodynamic performance in specific flight conditions, although these conditions are not yet fully understood. This led us to investigate the vortex dynamics and lift generation as a corrugated wing transitions from a stationary state to translational motion. The results reveal that suppression of secondary vortices generated on the wing significantly improves the overall performance of corrugated wings. This advances our understanding of flight dynamics and can also contribute to applications in engineering and biomimicry.
