The 15th test of China's reusable rocket engine was successful!"},"content":{"rendered":"

On April 12, the 130-ton reusable liquid-oxygen kerosene engine independently developed by the Sixth Academy of Aerospace Science and Technology Group successfully completed two start-up ground ignition tests. So far, the engine has completed a total of 15 repetitive tests, 30 ignition starts, the cumulative length of the test exceeded 3900 seconds, the number of repetitive tests exceeded the record number of tests of China's main engine of liquid rockets, laying the foundation for the subsequent first flight of China's reusable launch vehicles.<\/p>\n\n\n\n

Power comes first in the development of spaceflight. The prerequisite for the development of reusable rockets is to take the lead in developing a successful reusable engine. It is reported that, compared with traditional disposable rockets, reusable rockets will add four key technologies: first, \"accurate (landing)<\/strong>\", and two.\"have a good connection<\/strong>\", and three.\"last forever<\/strong>\", and four.\"quick fix<\/strong>\". And these key technology breakthroughs, the development of reusable engines bear the brunt. This type of engine as a follow-up to China's reusable launch vehicle main power, with high comprehensive performance, strong expansion capabilities, high reliability and other characteristics.<\/p>\n\n\n\n

In terms of design and development, the Sixth Academy's development team adheres to the development concept of \"technical limit mapping, extremely fast R&D iteration, and extreme product improvement\", and practices the spirit of \"must catch up with and exceed the world's advanced level\", and has answered the question of how to \"land accurately\" and \"connect steadily\" by mastering a number of core key technologies such as multi-ignition, wide-range inlet pressure, start-up, and wide-range variable thrust. By mastering multiple ignition, wide range of inlet pressure, wide range of variable thrust and other core key technologies, the institute has answered the question of how to \"land accurately\" and \"catch steadily\"; by breaking through the technologies of fast and simple maintenance and condition inspection and evaluation, the institute has solved the problem of \"not broken\" and \"repaired\". Through the breakthrough of fast and simple maintenance and condition inspection and assessment technologies, the problem of \"not broken\" and \"fast repair\" has been solved; through in-depth analysis of the mechanism, continuous optimization of the structure, and full implementation of test validation, the weak links of the engine are comprehensively managed, and the inherent reliability of the engine has been continuously improved.<\/p>\n\n\n

In terms of intelligent manufacturing, the development team of the Sixth Academy has planned and implemented 69 research projects for technological research and improvement based on a flexible and agile unitized manufacturing system and an efficient and integrated digital management and control system, and with the requirements of the key technical indicators of the reusable engine as the traction, the Sixth Academy is now planning and carrying out 69 research projects for technological research and improvement.Breakthrough in additive manufacturing one-piece molding of complex structural assemblies<\/strong>The company has established a core technology system for the production and manufacturing of reusable engines, and has significantly improved the advanced and stable engine technology, product quality consistency and reliability.<\/p>\n\n\n
