【Abstract】 Low altitude economy has become a new driving force for China’s economic growth. With its powerful transportation capabilities, advanced flight control systems, and reliable power support, ton-level large cargo drones have become important tools in logistics transportation, emergency rescue, and military supplies.The technological landscape of five representative ton-level cargo drone innovators in China(Shanghai Auto Flight, United Aircraft, Sichuan Tengden, Aerospace Times Feipeng, and Tianyu Hangtong) was analyzed based on patent bibliometrics. The research reveals that these companies all prioritize R&D and patent protection while demonstrating distinct technological characteristics. Their technology sources encompass acquisitions, transfers, and independent innovation. In terms of internationalization strategies, only Shanghai Auto Flight has systematically expanded into European and American markets, while others show significant disparities in global presence. The common technological focus centers on aircraft platforms, while simultaneously expanding into areas such as navigation and positioning, communication transmission, flight control, and logistics transportation. Shanghai Auto Flight distinguishes itself in vertical take-off and landing aircraft platforms and battery thermal management systems. United Aircraft specializes in the full-chain technology of “structure-control-system” for coaxial rotors. Sichuan Tengden leads in multi-drone collaborative control technology, encompassing formation planning and intelligent decision-making. Aerospace Times Feipeng is dedicated to establishing a comprehensive logistics chain technology system, achieving breakthroughs in precision airdrops and intelligent scheduling. Tianyu Hangtong concentrates on redundant control, intelligent cargo compartments, and autonomous navigation for large drones. Future development necessitates the integration of artificial intelligence with green energy technologies, enhancing the autonomy of core technologies, expediting international patent strategies, and bolstering international competitiveness through cross-institutional collaboration and standard-setting initiatives.更多还原
