Three tests in a day! The tests of rocket and satellite engine have succeeded.

According to the WeChat official account "China Aerospace Science and Technology Corporation," on April 10th, three major test areas of the Sixth Academy of China Aerospace Science and Technology Corporation's Beijing Aerospace Test and Technology Research Institute carried out parallel test missions and all achieved success.

The upper stage test area of the carrier rocket successfully completed the high-altitude calibration test mission of the YF-75D liquid oxygen/hydrogen engine. The institute continues to promote flexible, full-process, pulse-line operation test models, significantly increasing test efficiency and drastically shortening test cycles, with over ten tests per month.

The large-thrust engine test area of the carrier rocket successfully completed the ignition test mission of the oxidizer-rich gas generator for a certain engine. Through resource coordination to promote advanced elements and excellent product actions and continuous technical upgrades, the "liquid propulsion award-winning test stand" with a history of 67 years once again achieved remarkable results, continuously enhancing its capability to undertake test tasks for various engines.

The attitude control engine test area successfully completed the thermal calibration test task of the apogee engine used in satellites. The institute has strengthened the operational process-driven mechanism, achieving tight connections between each link of the test, effectively improving work efficiency; at the same time, it has applied automation technology to precisely regulate system status, further enhancing the ability to ensure success with high quality.

In the face of severe challenges posed by high-density test tasks, all test teams always remember their primary responsibility to strengthen the military, uphold the quality concept of "going to the test platform is like going to the launch pad," firmly aim for the goal of "one-time success" in testing, collaborate in operations, and fully guarantee the successful completion of model test tasks.
