... Calopteryx splendens in a steady air flow at Reynolds numbers of 700–2400 for the wings and 2500–15 000 for the bodies. The maximum lift coefficients ( C L,max ) were 1.07 for S. sanguineum and 1.15 for C. splendens , which are greater than those recorded for all other insects except the locust. The drag...

...J. M. Wakeling; C. P. Ellington ABSTRACT The free flapping flight of the dragonfly Sympetrum sanguineum and the damselfly Calopteryx splendens was filmed in a large flight enclosure at 3000 frames s −1 . The wingtip kinematics are described for these flights. Despite the two species being similar...

...J. M. Wakeling; C. P. Ellington ABSTRACT A mean lift coefficient quasi-steady analysis has been applied to the free flight of the dragonfly Sympetrum sanguineum and the damselfly Calopteryx splendens . The analysis accommodated the yaw and accelerations involved in free flight. For any given...
