The leapfrog development of UAV technology benefits not only from the upgrading of algorithms and control strategies, but also from the innovative empowerment of hardware technology. Researchers have made multiple breakthroughs in fields such as energy utilization and cooperative operations: Shen et al. introduced natural energy sources such as solar energy and wind energy into the UAV field through environmental energy harvesting technology, successfully breaking through the endurance limitations of traditional batteries and providing a new technical path for long-duration tasks such as environmental monitoring and disaster early warning; on this basis, the solar-hydrogen UAV combined with an energy hybrid system drives hydrogen fuel cells through solar energy, pushing the endurance capacity to a new height. Among them, the "Tianmushan-1" hydrogen-powered UAV developed by Beihang University (Beijing University of Aeronautics and Astronautics) has set a world record of uninterrupted flight exceeding 188 kilometers. Meanwhile, Wang et al. realized accurate trajectory prediction through multi-view complementary design, effectively solving the cooperative operation problem of UAVs under communication-constrained conditions. Similar technologies have been applied in the swarm UAV system of the National University of Defense Technology, enabling a single soldier to command more than 200 UAVs for autonomous collaboration and dynamic division of labor.
