Core Viewpoint - The successful "tethered ignition test" of the Long March 10 series rocket marks a significant milestone in China's manned lunar exploration program, demonstrating advancements in rocket technology and testing capabilities [1][4]. Group 1: Test Overview - The tethered ignition test is a ground test simulating the rocket's flight state without actual launch, where the rocket is securely fixed to the test platform during ignition [3][4]. - The test utilized a sub-module of the Long March 10 rocket, measuring 5 meters in diameter and 25 meters in height, generating nearly 1,000 tons of thrust, setting a new record for China's rocket engine testing [4][9]. Group 2: Technical Details - The Long March 10 rocket consists of three modules, with the test's thrust being one-third of the total launch thrust, ensuring safety and control during the test [4][6]. - The test was conducted at the launch site due to the lack of a testing platform capable of handling the thrust levels required for the engine tests [4][6]. Group 3: Development Process - The Long March 10 series is designed for manned lunar missions and includes two configurations, with the ignition test validating key technologies such as multi-engine parallel operation and fault diagnosis [8][9]. - The testing process involves a "four-step" approach to validate the rocket's power system, with the tethered ignition test representing the second step following a successful initial test in June 2024 [11][12].

Core Viewpoint - The successful tethered ignition test of the Long March 10 series rocket marks a significant step in China's space exploration efforts, particularly for manned lunar missions and space station launches [1][7]. Group 1: Test Overview - The tethered ignition test is described as a "non-launch" ignition firing, representing the closest ground test to actual flight conditions [1]. - The test utilized a sub-level test rocket with a diameter of 5 meters and a height of 25 meters, generating nearly 1,000 tons of thrust from its seven engines, setting a new record for rocket engine testing in China [3]. - The Long March 10 rocket consists of three modules, with the launch thrust being three times that of the test [3]. Group 2: Technical Aspects - The test was conducted at the launch site due to the lack of domestic test platforms capable of handling 1,000-ton class engine tests [5]. - The ignition test fully validated the power system module of the Long March 10 series, focusing on key technologies such as multi-engine parallel operation and fault diagnosis [9]. - The test is part of a four-step process for the Long March 10 series rocket's power system, which is crucial for determining the rocket's payload capacity, flight performance, and mission reliability [10]. Group 3: Future Steps - The tethered ignition test is the second step in the power system testing process, following a successful initial test in June 2024, which was akin to a "small exam" [12]. - Future tests will include low-altitude flight and a true orbital test with all seven engines [14].
不起飞的“点火发射”怎么做到的?长征十号系列火箭需闯“四道关”

Core Viewpoint - The recent ground test of the Long March 10 series rocket represents a significant milestone in China's space exploration efforts, focusing on the validation of the rocket's propulsion system and its readiness for future missions [1][3]. Group 1: Test Overview - The test is described as a "tethered ignition launch," where the rocket is securely fixed to the test platform to prevent it from taking off [1]. - The Long March 10 rocket's first stage test vehicle has a diameter of 5 meters and a height of 25 meters, generating nearly 1,000 tons of thrust during the ignition test, setting a new record for China's rocket engine testing [1]. - The Long March 10 rocket consists of three modules, with a launch thrust three times that of the recent test [1]. Group 2: Technical Details - To prevent excessive thrust from causing the rocket to detach from the test platform, over 200 bolts were used to securely connect the test vehicle to the platform, ensuring a safe and controlled test [2]. - The test was conducted at the launch site due to the high requirements for the test platform, as there are currently no facilities in China capable of handling a thousand-ton class engine test [3]. - The Long March 10 series is designed for manned lunar exploration and includes two configurations, with specific missions for lunar landing and space station launches [3]. Group 3: Testing Phases - The ignition test is part of a four-step process for the Long March 10 series rocket, which is the largest thrust scale full-system test conducted in China [4]. - The propulsion system is critical for the rocket's payload capacity, flight performance, and mission reliability, with the ignition test aimed at identifying issues during the rocket's development [4]. - The recent tethered ignition test builds on the success of the first dynamic system test conducted in June 2024, which involved parallel ignition of three engines, marking the first step in the testing process [4].

Core Viewpoint - The successful ignition test of the Long March 10 series rockets marks a significant milestone in China's manned lunar exploration program, following previous successful tests of the crewed spacecraft and lunar lander [2][7]. Group 1: Technical Requirements - The Long March 10 series rockets are designed to meet the high payload capacity requirements for manned lunar missions, specifically needing to deliver at least 27 tons to the translunar trajectory, which current rockets cannot achieve [3]. - Existing rockets like the Long March 2F, Long March 7, and Long March 5 have significantly lower payload capacities when adjusted for translunar missions, highlighting the necessity for a new rocket platform [3]. Group 2: Reliability and Precision - The manned lunar mission requires rockets with enhanced reliability and safety features due to the long mission duration and extreme environments, necessitating advanced designs such as redundancy systems and intelligent fault diagnosis [4]. - High precision in launch and orbital insertion is critical, as two rockets must launch in a strict sequence to ensure successful docking in lunar orbit, demanding high accuracy and flexible launch windows [5]. Group 3: Rocket Specifications - The Long March 10 series includes two configurations: Long March 10, a three-stage rocket with a height of 92.5 meters, and Long March 10A, a two-stage rocket with a height of 67 meters, designed for different mission profiles [7]. - The Long March 10A features a reusable first stage, aimed at optimizing costs and resource utilization for both lunar and space station missions [7].
