Recently, Kyushu Cloud Arrow's "Longyun" 80-ton-class high-thrust liquid oxygen-methane engine successfully completed a deep thrust-vectoring hot-fire test evaluation, marking a complete success for the experiment.
Recently, the Longyun 80-ton-class high-thrust liquid oxygen-methane engine developed by Jiuzhou Yunjian successfully completed a deep thrust-ratio hot-fire test evaluation, marking a complete success for the experiment.
This test drive features several notable characteristics:
1. China has, for the first time, achieved deep thrust modulation of a high-thrust liquid oxygen-methane rocket engine, with its thrust regulation capability (throttling down to 50% operating conditions) reaching world-class advanced levels.
2. The adaptability of Jiuzhou Yunjian's thrust regulation technology has been further assessed and verified on high-thrust engines, with test results demonstrating that the regulation system is fully compatible with such engines.
3. The successful multiple ignition tests and deep-thrust thermal tests of the Longyun engine signify that China has mastered the technology for high-thrust, recoverable liquid oxygen-methane engines.
The successful deep-thrust thermal tests of the "Lingyun" and "Longyun" engines developed by Kyushu Yunjian mark significant milestones, confirming the feasibility of using high-thrust liquid oxygen-methane engines as primary propulsion systems in reusable launch vehicles. This achievement provides a critical power foundation for China's advancement in reusable launch vehicle technology. Moving forward, the "Longyun" engine will undergo further rigorous evaluations, including extended-duration thermal testing.
