Albatross’s dynamic soaring could help drones fly longer using winds

UC Assistant Professor Sameh Elsa and his team are developing drones inspired by the albatross, a large seabird known for its ability to fly long distances without flapping its wings. Funded by a $700K DARPA grant, the project leverages biomimicry to replicate the albatross’s dynamic soaring technique. This flight method involves the bird repeatedly turning into the wind to gain altitude, then gliding forward using gravity and wind currents near the water’s surface, allowing it to stay airborne for hours efficiently. Albatrosses can cover hundreds of miles weekly, cumulatively flying distances far exceeding that between the Earth and the moon over their lifetimes. The research highlights the albatross’s sophisticated real-time flight optimization, which even advanced computers struggle to replicate. The birds use sensitive sensory input, including their keen sense of smell, to make precise flight adjustments, solving complex optimization problems instinctively. To mimic this, drones must measure changing wind speeds and directions and adjust their flight
