China Spacesat(SH:600118) Yang Shi Wang·2025-08-16 04:47Core 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].
