天龙三号液体运载火箭一级动力系统海上试车成功

Core Viewpoint - The Tianlong-3 liquid launch vehicle, developed by Beijing Tianbing Technology Co., has successfully completed its first-stage power system test on September 15 at the Haiyang Dongfang Spaceport in Shandong, marking a significant milestone in China's space launch capabilities [1][3]. Group 1: Vehicle Specifications - The Tianlong-3 rocket, which began development in March 2022, has a total length of 72 meters and a launch weight of approximately 600 tons [2]. - It is equipped with nine "Tianhuo-12" engines working in parallel, providing a payload capacity of 17 to 22 tons for low Earth orbit and 10 to 17 tons for sun-synchronous orbit [2]. Group 2: Technical Validation - The recent test validated several key technologies, including wind resistance, anti-vibration, lightning protection, salt fog resistance, noise reduction, environmental protection, and high-temperature flame protection for the engines [4]. - During the test, all systems operated normally, with accurate engine start sequences, stable operation, and proper shutdown, meeting the performance requirements for the rocket's maiden flight [4]. Group 3: Future Plans - The Tianlong-3 rocket is scheduled to execute its maiden flight by the end of 2025, supporting large-scale cargo transport needs for China's space station and mid-to-high orbit satellite launches [2][4].
