The Characterization Of Wing-Wing Vortex Interactions Of A Tandem Flapping Wing Configuration And Its Relationship To The Phase Angle And Wing Spacing., Timothy Michael Broering 1985-

Electronic Theses and Dissertations

A number of flying insects make use of tandem wing configurations, suggesting that such a setup may have potential advantages over a single wing at low Reynolds numbers. Dragonflies, which are fast and highly maneuverable, demonstrate well, the potential performance of such a configuration. In a tandem wing configuration, the hindwing often operates in the wake of the forewing and, hence, its performance is affected by the vortices shed by the forewing. Changes in the phase angle between the flapping motions of the fore and hind wings, as well as the spacing between them, can affect the resulting vortex/wing and …
