Wingtip-Vortex Turbine Lowers Aircraft DragTurbine captures some of energy lost in aircraft wingtip vortexes. Wing-tip vortex turbine operates in crossflow of the lift-induced vortex; i.e., flow not parallel to the flightpath. Each turbine blade generates a force as a result of angle of attack between blade and nonstreamwise local flow. Turbine converts lost vortex energy to rotational energy and reduces induced drag.
