4月10日，中國航天科技集團有限公司六院北京航天試驗技術研究所大推力試驗區、上面級試驗區、姿軌控試驗區三大試驗區並行推進試驗任務，均獲成功。

The upper stage test area of the launch vehicle successfully completed the high-modulus calibration test task of the YF-10D hydrogen-oxygen engine. The institute continued to promote the flexible, full-process, pulsating line operation test mode, which greatly improved the test efficiency, greatly shortened the test cycle, and exceeded 0 tests per month.

▲ The No. 6 station carried out the high-altitude simulation test of the YF-75D hydrogen-oxygen engine

The high-thrust engine laboratory of the launch vehicle successfully completed the ignition test task of the oxygen enrichment generator of an engine. By coordinating resources to promote advanced units and excellent product actions, the institute continues to carry out technological upgrading, and the "Aerospace Liquid Power Meritorious Test Bench" with a long history of 67 years has made new contributions, and its ability to undertake multi-type engine tasks has been continuously improved.

▲ The No. 2 "Liquid Power Meritorious Test Bench" was used for gas generator testing

The attitude and orbit control engine area successfully completed the test task of the thermal elevation module of the apogee engine for satellites. By strengthening the driving mechanism of the operation process, the institute has realized the close connection of all aspects of the test and effectively improved the work efficiency. At the same time, automation technology is applied to accurately control the state of the system to further improve the ability to ensure success with high quality.

▲ No. 1 / GS-1 high-altitude station conducts high-altitude test of satellite engine

In the face of the severe challenges of high-density test tasks, each test team has always kept in mind the primary responsibility of strengthening the army, adhered to the quality concept of "getting on the test pad is on the launch pad", firmly anchored the goal of "one success" in the test, and worked together to ensure the smooth completion of the model test task.
