东方空间研制的首型火箭"引力一号"经过3年的高效研制，于2024年1月11日从东方航天港登船，在烟台 海阳海上首飞成功。首飞后成为全球最大固体运载火箭、国内民商最大火箭。 "我们在火箭研制过程中，进行了许多尝试和创新。"彭昊旻说，在"引力"系列火箭设计之初，将箭体结 构模块化——统一了火箭芯级与助推器的直径、将固体助推器与芯级发动机的接口标准化，这种标准化 设计，可以支持生产环节中集中备料和快速批量化制造，也可以根据未来任务需求灵活调节配置，像火 箭像积木一样，大大提升了"引力"系列火箭生产效率；研发的充气式防护罩（又称"气膜火箭防护罩"） 是火箭发射保障体系中的一项创新技术。这项技术类似于"充气城堡"，相当于给火箭穿上了"羽绒服"， 替换掉了传统的火箭金属防护服，通过技术创新降低了成本；"引力一号"在"东方航天港"5公里内完成 总装、测试、发射全流程，通过地理集中化与流程集约化，"前店后厂"的发射模式彻底重塑了传统火箭 发射流程，是一项重大模式创新。相比传统陆上发射场，效率提升显著，最高可实现"一周一箭"的发射 频率。 彭昊旻透露，目前，东方空间的第二型"引力二号"大型可回收液氧煤油火箭正在进行方案设计，预 ...

Core Viewpoint - The successful tethered ignition test of the Long March 10 rocket series marks a significant technological milestone for China's manned lunar exploration program, paving the way for future missions [1][3]. Group 1: Mission and Design - The Long March 10 rocket series is designed to support China's goal of landing humans on the moon by 2030, requiring a high-safety, high-reliability, and high-thrust launch vehicle [2]. - The rocket features a modular design that allows for independent assembly and different configurations, with two versions: the lunar version and the near-Earth version [2]. - The Long March 10 is a three-stage rocket with a core diameter of 5 meters, intended to launch the crewed "Dream Boat Y" spacecraft and the lunar lander [2]. Group 2: Testing and Development - The tethered ignition test is the first of its kind conducted at a launch site for the Long March series, establishing a crucial technical foundation for the lunar exploration mission [3]. - This test involved a short-duration ignition of seven engines simultaneously, utilizing a temporary setup due to the lack of a dedicated test stand for such a configuration [3][4]. - The test achieved a thrust scale of nearly 1,000 tons, making it the largest full-system test conducted domestically [4]. Group 3: Future Plans - The ignition test is part of a four-step process for the Long March 10's engine testing, with subsequent tests planned to further validate the rocket's capabilities [5]. - Future tests will include low-altitude flight tests and actual orbital flight validation, contributing to the development of a new manned space transportation system [5].

Core Viewpoint - The Long March 2F rocket successfully launched the Shenzhou-20 manned spacecraft, achieving high reliability and safety ratings, highlighting its role as a critical asset in China's manned space missions [1][2] Group 1: Rocket Performance and Reliability - The Long March 2F rocket has a reliability assessment value of 0.9905 and a safety assessment value of 0.99996, making it the only active manned launch vehicle in China [1] - The design philosophy of the Long March 2F incorporates "one fault work, two fault safety," emphasizing redundancy and margin design to enhance reliability [1][2] Group 2: Technological Innovations - The rocket's development team achieved several firsts, including the creation of a fault detection and handling system and a large-capacity real-time escape telemetry system [1] - The design system mandates that key parameters must have a 20% safety margin, ensuring that only high-quality components are selected for the rocket [2] Group 3: Future Operations - The Long March 2F rocket is expected to conduct two launches annually as part of the ongoing operations of the space station [2] - The development team plans to enhance work efficiency through the use of information and digital tools, ensuring robust support for the space station's regular operations [2]
