...J. M. Wakeling; C. P. Ellington ABSTRACT The free gliding flight of the dragonfly Sympetrum sanguineum was filmed in a large flight enclosure. Reconstruction of the glide paths showed the flights to involve accelerations. Where the acceleration could be considered constant, the lift and drag forces...

...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...
