On October 21st, Arrowyuan Technology announced that the combined swing hot tests for the first and second stage engines, along with their servo mechanisms, of the Yuanxingzhe-1 rocket had been successfully completed in sequence and that the components had been delivered for final assembly. The tests confirmed that the engines operated smoothly, with the servo mechanisms executing all required swing actions precisely as instructed. All measured parameters met or exceeded the established standards. This series of tests thoroughly verified the coordination, compatibility, and reliability of the engines and servo mechanisms under actual ignition conditions. Additionally, the precision of the first-stage engine’s continuous variable thrust was validated, providing a strong technical foundation for Yuanxingzhe-1’s inaugural flight, orbit insertion, and subsequent recovery operations.
