Numerical Investigation on Flapping Aerodynamic Performance of Dragonfly Wings in Crosswind by Chao Wang, Rui Zhang, Chaoying Zhou, Zhenzhong Sun

“…These may accelerate the lateral skewing of the dragonfly, and the increased rolling and pitching moments will further aggravate the instability of the dragonfly model. The vorticities and reattached flow on the wings move laterally to one side due to the crosswind, and the pressure on wing surfaces is no longer symmetrical and hence, the balance between the aerodynamic forces of the wings on two sides is broken. …”
