Webof extracting the flow kinetic energy resident in the wake of a lifting surface. Traditionally, this energy savings is accomplished by a following vehicle appropriately capturing the wingtip vortices shed by a leading vehicle.4 As early as the 1920s42 approximations of the energy savings due to formation flight have been examined. WebApr 30, 2013 · Formation flight is widely used by migrating birds. Each wing flies in an upwash field generated by all other wings in the formation, and this leads to a reduction in flight power demand for each wing as well as for the whole formation.
