Recently, the "Longyun" liquid oxygen-methane engine developed by Jiuzhou Yunjian successfully completed a long-duration hot-fire test at rated conditions on Test Stand No. 2 at the Bengbu Testing Base. During this test, all engine systems operated normally, and the engine's performance metrics met the anticipated targets, marking a complete success for the hot-fire test.
This test drive has achieved two significant breakthroughs:
01 New workstation
This hot test run was conducted at Workstation No. 2 of the Jiuzhou Yunjian Bengbu Test Base, a dedicated facility specifically designed for 100-ton-class engines. Prior to this, Workstation No. 2 had already successfully completed the acceptance tests on the test bench. With the full operational capacity of its dual 100-ton-class workstations now in place, the facility will fully ramp up its efforts in 2022 to comprehensively support the delivery of two types of engine models.
02 Increased Thrust
After rapid iterative development, the "Longyun" engine achieved a rated thrust of 677 kN and a ground-specific impulse of 291 seconds during this round of hot-fire testing. It is currently the largest liquid oxygen-methane engine known in China, as well as the country's only large-thrust liquid oxygen-methane engine that has fully mastered the technology for rocket recovery and reuse.
