The "Nine Heavens" unmanned aerial vehicle designed by the Aviation Industry First Flight Institute successfully completed its maiden flight mission in Pucheng, Shaanxi on the 11th, marking a new breakthrough in China's large-scale unmanned aerial vehicle technology. As a large-scale general-purpose unmanned aerial vehicle platform for independent innovation in China, the "Jiutian" unmanned aerial vehicle adopts the design concept of "general-purpose platform+modular mission payload", and has core advantages such as large payload capacity, high lift limit, wide speed range, and short takeoff and landing. This type of aircraft has a length of 16.35 meters, a wingspan of 25 meters, a maximum takeoff weight of 16 tons, a payload capacity of 6000 kilograms, a flight time of 12 hours, and a transfer range of 7000 kilometers. Its performance indicators rank among the top of similar products. Through modular task payload replacement, the "Jiutian" drone can be widely adapted to various scenarios, including heavy material transportation and precise logistics delivery in remote mountainous areas and islands, rapid recovery of communication and delivery of disaster relief equipment in emergency rescue, as well as providing services such as geographic mapping, disaster assessment, and mineral survey.
