In a nod to the natural prowess of one of the ocean's most efficient fliers, researchers at the University of Cincinnati are drawing on the remarkable abilities of the albatross to inspire the next wave of drone technology, working to create drones that can soar on wind currents with hardly a beat of their wings, this cutting-edge project has been spotlighted by Earth.com and is being undertaken at the UC College of Engineering and Applied Science under the guidance of Assistant Professor Sameh Eisa with the help of a grant from the Defense Advanced Research Projects Agency, tasked with creating a drone capable of mimicking the albatross's dynamic soaring.
The albatross, renowned for having the largest wingspan of any living bird, exploits the wind in a way that has now captured the attention of aerospace engineers. It ascends by tacking into the wind much like a sailboat, climbing into faster air currents to gain lift and altitude, then when its forward momentum wanes, the bird executes a turn to utilize the kinetic energy of gravity and wind, pushing it forward in a way that conserves energy, a feat of nature's engineering that the UC team hopes to replicate in drone design, with Eisa explaining, as detailed by University of Cincinnati news release, "Nature has been optimizing flight for millions of years of evolution. So to take this gift from nature and make it available to humanity is engineering at its best."
These birds are attuned to wind speeds and directions through highly sensitive nostrils, enabling them to finely adjust their flight to make the most of every ascent and descent on their glide path. This sensory sophistication offers a blueprint for the drones being developed, which aim to navigate air currents with similar precision and efficiency. UC engineering students are developing drones inspired by the albatross’s flight, allowing them to operate longer without constant power. This innovation could transform surveillance, research, and delivery systems.
