国内首款3D打印航空发动机完成飞行试验；中国科研团队研究成果为提升钙钛矿电池稳定性提供新思路丨智能制造日报

Group 1 - The first domestically developed 3D printed turbojet engine has successfully completed its maiden flight test, filling a gap in the application of 3D printing technology in engine manufacturing in China. The engine operated stably in high-altitude complex environments, meeting all design parameters, and demonstrated reliability. The test flight was conducted in Dingbian County, Shaanxi, with the drone flying for 30 minutes, reaching a maximum speed of 0.75 Mach and an altitude of 6000 meters. No damage or failure was observed in any engine components after the test [2]. - The domestically produced manned airship, Xiangyun AS700, has achieved the first commercial flight in China, completing a round trip from Jingmen to Wuhan. This airship is the first in China designed according to airworthiness standards and possesses complete independent intellectual property rights for short-distance and vertical takeoff and landing [2]. - A research team from Xi'an Jiaotong University and Xiamen University has proposed a new solid-state molecular imprinting annealing strategy to enhance the stability of perovskite solar cells. This research was published in the international journal "Science" [2]. - The first domestically produced BOPP production line with a width of 9.1 meters has been successfully launched in Guilin, marking a significant breakthrough in core technology in the high-end film equipment sector. This production line increases the maximum width of similar domestic equipment from 8.7 meters to 9.1 meters and features low consumption, high efficiency, and green advantages. The produced BOPP film has excellent mechanical and electrical properties, as well as outstanding cold resistance and gas tightness, making it widely applicable in high-end packaging fields such as electronics and medical supplies [2].
