Figure-eight systems

Definition

Figure-eight systems are a type of airborne wind energy system that utilize a figure-eight flight path to harness wind energy effectively. These systems operate by flying a tethered kite or drone in a continuous loop, generating lift and traction to convert wind energy into usable power. The figure-eight trajectory allows for efficient energy capture across varying wind conditions and enhances the system's performance by maximizing the time spent in high-lift regions.
