蓝箭：卫星这样叠

Core Viewpoint - Blue Arrow Aerospace has achieved a significant breakthrough in the "one rocket multiple satellites" technology, enhancing its capabilities for large-scale satellite internet constellation deployment [1][3]. Group 1: Technological Advancements - The successful completion of the multi-satellite stacking release mechanism and satellite assembly vibration and unlocking impact tests indicates that Blue Arrow Aerospace's self-developed technology is now capable of supporting large-scale satellite internet constellation networking [3]. - The multi-satellite stacking release mechanism is essential for the "one rocket multiple satellites" launch mission, ensuring that multiple satellites are securely fixed as a single assembly during ground preparation, rocket launch, and orbital insertion [3][5]. - The inter-satellite locking mechanism has been developed to enhance the safety and orderliness of the separation process, simplifying the satellite docking process at the launch site [3][5]. Group 2: Mechanism Specifications - The stacking release mechanism consists of pneumatic separation nuts, stacking columns, release rods, lifting mechanisms, and buffering mechanisms, utilizing four sets of stacking columns and eight carbon fiber release rods to effectively secure flat-panel satellites [5]. - The inter-satellite locking mechanism includes an unlocking motor and locking module, employing a non-explosive drive scheme that offers multiple advantages over traditional explosive bolt methods, such as higher reliability, repeatable testing, lower pollution, reduced unlocking impact, lower costs, and a controllable supply chain [5]. Group 3: Testing and Results - The tests covered both horizontal and vertical acceptance and verification levels, confirming that the satellite assembly remains stable under compression, with vibration characteristics fully meeting design requirements [5]. - The unlocking impact is minimal, with high synchronization, ensuring compatibility with satellite bodies, and all indicators meet engineering application conditions [5]. Group 4: Market Implications - Blue Arrow Aerospace currently possesses the Zhuque-2 improved version and Zhuque-3 rockets capable of undertaking satellite internet constellation networking tasks [5]. - The successful development of the multi-satellite stacking release mechanism and inter-satellite lock further expands Blue Arrow Aerospace's "star-rocket integration" launch solution, enhancing its market service capabilities and significantly contributing to the rapid construction of China's satellite internet constellation [5].
