On June 23, 2024, Jiuzhou YunJian Longyun liquid oxymethane engine Completed at Jiuquan Dongfeng Launch Site 10km Class III flight recovery test, the test is a complete success!

This test is of great significance:

1. JiuZhouYunJian Longyun liquid oxygen methane engine was first completed For the first time in China 10km Level flight recovery test.

2. This test is the first flight recovery application of engineering rockets in China Multi machine parallel connection The form of participation in the test is the closest to Launch into orbit Recovery test.

3. Longyun engine participated in the flight mission assessment for the first time, all parameters were normal during flight, and the engine successfully completed various actions such as startup, shutdown, swing, thrust adjustment, etc. 

At present, Longyun engine has completed the second phase of thrust lifting, and the engine sea level thrust has reached 745kN , specific impulse at sea level 293s , engine thrust weight ratio> one hundred. The thrust lifting of the Longyun engine will continue.

Follow-up, Longyun engine Will cooperate with private rocket companies in the second half of this year Jianyuan Technology develop aeromarine flight and Splash recovery test 。
