北航吴江浩教授团队研发的首个具备自主悬停能力的仿蜂鸟微型飞行器

Group 1 - The article discusses the successful development of China's first micro flying device that mimics a hummingbird, capable of autonomous hovering and advanced flight maneuvers [2][5][12] - The micro flying device weighs less than an egg and can achieve a flight time exceeding 15 minutes, making it the only one in its category to do so [2][21] - The research team, led by Professor Wu Jianghao from Beihang University, has spent over ten years on this project, overcoming significant engineering challenges [2][8] Group 2 - The hummingbird's unique flight capabilities, such as its ability to hover and perform rapid maneuvers, make it an ideal model for micro flying devices [5][12] - The team developed a four-bar linkage mechanism and used high-strength nylon composite materials to enable the wings to flap at high frequencies without breaking [15][17] - A lightweight wing structure was created using carbon fiber and polyimide film, allowing the device to generate lift greater than its own weight [17][19] Group 3 - The micro flying device features a 1.8-gram flight control board that integrates sensors and communication modules, enabling rapid response to environmental disturbances [19][21] - The innovative "wing-body coupling control" mechanism allows the device to maintain stability in complex environments, achieving rapid rotations [19][21] - The device is not just a technological novelty but is designed for practical applications, such as search and rescue operations and wildlife monitoring [21][25] Group 4 - The project represents a significant achievement in biomimetic technology, showcasing the integration of natural principles into engineering [25][28] - The development journey from initial flights in 2017 to stable operations and public exhibitions reflects a commitment to learning from nature [25][28] - The article emphasizes the importance of this technology as a testament to human ingenuity in responding to natural designs [28]
