这回相当于“中考” 长征十号火箭动力系统试验“四步走”

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].
