央视网消息：8月15日，我国在文昌航天发射场成功组织实施长征十号系列运载火箭"系留点火试验"。这是我国载人月球探测工程研制工作取 得的又一项重要阶段性突破。此次试验名为"系留点火试验"，什么是"系留"，"系留"又将如何进行？ 此次试验可以看作一次不起飞的"点火发射"，是火箭最接近飞行状态的大型地面试验。所谓"系留试验"就是将试验箭体牢牢固定在试验平台上 点火试车，拴住它不要让它飞走。 试验所使用的箭体是长征十号系列运载火箭一子级试验箭，直径5米、高25米。在点火过程中，试验箭的7台发动机产生近千吨的推力，创造了 我国火箭发动机试车推力的新纪录。 而长征十号火箭是由3个这样的火箭模块组成，起飞推力是这次试验的3倍。为了避免推力过大导致火箭脱离试验平台，研制人员通过200多个 螺栓将试验箭体与试验平台相固连，确保试验顺利进行，安全可控。 据介绍，发动机试车对试验台的要求极高。目前，我国还没有能够满足千吨级发动机试车的试验台，研制团队因此将试验搬到了发射场来进 行。 徐洪平表示，之后再结合回收的一些技术验证，做一个低空飞行，然后再做一个7台发动机真正入轨的技术验证分析。 中国航天科技集团彭越介绍，由于这型火箭的推力 ...

Core Viewpoint - China's new generation manned lunar landing carrier rocket, the Long March 10 series, has achieved significant breakthroughs in its development, marking an important milestone in the country's lunar exploration program [1][6]. Group 1: Development and Technical Requirements - The Long March 10 series is designed to meet the complex technical requirements of manned lunar missions, which exceed those of low Earth orbit tasks [3]. - The engineering plan requires two rockets to accurately deliver the lunar lander and the new generation manned spacecraft into the translunar transfer orbit, necessitating a payload capacity of no less than 27 tons [3][4]. - Current active rockets in China, such as the Long March 2F, Long March 7, and Long March 5, do not meet this 27-ton requirement for translunar transfer [4]. Group 2: Reliability and Precision - The manned lunar exploration program adopts a "two launches, lunar rendezvous" approach, which imposes higher reliability and safety standards on the rocket systems [5]. - The design standards for the new generation carrier rocket include redundancy, escape systems, and intelligent fault diagnosis to ensure astronaut safety and mission success [5]. - High precision in launch and orbit insertion is critical, requiring the rockets to deliver their payloads into the translunar transfer orbit within strict timing sequences [5]. Group 3: Long March 10 Series Overview - The Long March 10 series consists of two configurations: Long March 10 and Long March 10A, specifically developed for manned lunar exploration [6]. - Long March 10 is a three-stage rocket with a diameter of 5 meters and a maximum height of 92.5 meters, designed to launch the manned spacecraft and lunar lander [7]. - Long March 10A is a two-stage rocket with a recoverable first stage, aimed at supporting both lunar missions and space station operations [7].

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, aiming for a lunar landing by 2030 [1][2]. Group 1: Mission and Design - The Long March 10 rocket series is designed for both manned lunar missions and cargo transport, featuring two versions: the lunar version and the near-Earth version [2]. - The Long March 10 rocket is a three-stage rocket with a core diameter of 5 meters, while the Long March 10A is a two-stage rocket with a reusable first stage [2]. Group 2: Testing and Development - The tethered ignition test is a crucial step in the rocket development process, allowing for the verification of the propulsion system under controlled conditions [2][3]. - This test is the first of its kind conducted at the launch site for the Long March series, providing a vital technical foundation for the lunar exploration mission [2][3]. - The test achieved a thrust scale of nearly 1,000 tons, making it the largest full-system test conducted domestically [3]. Group 3: Future Plans - The Long March 10 rocket's development will proceed in four phases, with the tethered ignition test being the second phase, followed by additional ignition tests and a low-altitude flight test [4]. - Future tests will include a true orbital flight validation, further advancing the capabilities of China's manned space transportation system [4].

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].
