Recently, the 10-ton "Lingyun" engine developed by Jiuzhou Yunjian successfully completed two rounds of engine gimbal tests at the Bengbu test site. During these two hot firing tests, all systems operated normally, and key performance indicators met expectations, marking a complete success for the trials.
Recently, the 10-ton "Lingyun" engine developed by Jiuzhou Yunjian successfully completed two rounds of engine gimbal tests at the Bengbu test site. During these two hot firing tests, all systems operated normally, and key performance indicators met expectations, marking a complete success for the trials.
The "Lingyun" engine employs a pre-pump gimbal scheme, utilizing an electromechanical servo mechanism to achieve ±8° bidirectional gimbal motion, thereby enabling thrust vector control. This pre-pump gimbal technology features a compact structural layout and minimal flow resistance, making it widely adopted in upper-stage engines for launch vehicles.
This round of swing tests successfully achieved a maximum swing angle of ±8°, encompassing sine-wave circular motion, square-wave positioning, frequency sweep, and triangular-wave oscillation tests. Additionally, combined engine thrust variation and thermal swing tests were conducted to verify the compatibility between the engine's variable thrust capability and the servo system operations. These tests comprehensively validated the control requirements for subsequent flight missions.
As of now, Lingyun Engine has completed thousands of seconds of cumulative hot-fire tests. Multiple key technologies have been successfully validated, including multiple ignition cycles, deep thrust modulation, and cost-effective operation and maintenance. Additionally, the engine has already passed the customer's pre-flight reliability hot-fire test for their rocket systems. Moving forward, Jiuzhou Yunjian will continue to focus on developing reusable liquid oxygen-methane propulsion systems, consistently contributing Jiuzhou's expertise to the advancement of China's commercial space industry!
