US military backs wind-riding drone concept inspired by birds

The US military, through DARPA, is funding the Albatross project, a research initiative inspired by the soaring flight techniques of birds like the albatross, which can glide long distances using rising warm air and shifting wind patterns without flapping their wings. Researchers from The University of Texas at El Paso (UTEP), Mississippi State University, and Embry-Riddle Aeronautical University are developing autonomous drone technology that mimics these natural air patterns to significantly reduce energy consumption in uncrewed aircraft systems (UAS). The project aims to enable drones to exploit small, short-lived, and unpredictable air currents to extend flight duration and range beyond current battery limitations. The scientific principle behind the project involves drones detecting and utilizing rising thermal air currents—similar to how birds soar—to stay aloft with minimal power use. This approach could revolutionize drone operations by making them more energy-efficient and capable of longer missions, which is particularly valuable for applications such as environmental monitoring, disaster response, and military surveillance.
