It can achieve the ability to continuously conduct high-altitude simulation tests for engines in vacuum working environments below kilopascals for thousands of seconds, greatly improving China's aerospace hydrogen and oxygen engine testing capabilities and levels. It will provide important test support conditions for the development of hydrogen and oxygen engines for China's Long March 10 carrier rocket. It is understood that the project team has achieved real-time health diagnosis of the testing system and fully digital management of the testing process through scaling test verification, digital simulation, and process reengineering, ensuring the reliability of the testing system and meeting the requirements of high-altitude simulation testing for model engines.
