Core Viewpoint - Beijing Tianbing Technology Co., Ltd. successfully completed the world's first offshore test of a large liquid launch vehicle's first-stage propulsion system, marking a significant milestone in China's commercial space industry and enhancing its capabilities in satellite internet deployment [1][2]. Group 1: Test Platform and Capabilities - The "HOS-1" platform, developed by Shandong Maritime Commercial Space Launch Service Co., is China's first semi-fixed offshore test platform, designed for safe and efficient operations away from land [2]. - The successful test on the "HOS-1" platform demonstrates its capability to conduct tests for liquid oxygen-kerosene or liquid oxygen-methane propulsion rockets with a length of up to 72 meters and a diameter of up to 3.8 meters, marking a breakthrough from single-machine to multi-machine testing [2]. Group 2: Technical Specifications and Performance - The Tianlong-3 rocket, which is expected to perform its maiden flight by the end of 2025, is designed to carry over 20 tons to low Earth orbit, making it comparable to SpaceX's Falcon 9 [3]. - The rocket's first stage is equipped with nine "Tianhuo-12" engines, with a total launch weight of approximately 600 tons and a length of 72 meters, capable of launching 36 satellites in a single mission [3]. Group 3: Technological Innovations - Tianbing Technology has integrated significant technological advancements, including the use of 3D printing for about 90% of the "Tianhuo-12" engine components, which has significantly reduced the development cycle [4]. - The use of coal-based aerospace kerosene, validated by the Tianlong-2, has effectively lowered fuel costs and improved engine reusability through sulfur separation technology [4]. - The company has developed a three-redundancy computer system using industrial-grade components, ensuring high reliability while significantly reducing system costs [4].
