Beijing Aerospace Experiment Technology Research Institute conducted three complete sets of the first engine of the three-stage hydrogen-oxygen engine of a new generation of manned launch vehicles on platform 6. The long-range test on the ground was a complete success. So far, the development goal of the engine in the deep-closing stage has been successfully completed, and it has set a record for the ignition frequency and longest duration of this type of engine and the test bench in a single day.

In the case of the surge in the number of test tasks, in the last week before the National Day, the large thrust area, the upper stage area, the attitude and orbit control area of the Beijing Institute of Aerospace Experiment Technology, and multiple test stations were advanced in parallel, successfully completing the high-thrust hydrogen-oxygen engine. , a new generation of manned carrier rocket three-stage engine, and a probe orbit control engine, represented by 12 ignition tests, completed various aerospace major engineering support tasks with high quality and high efficiency, and used practical actions to welcome the 73rd anniversary of the motherland and the party’s The Twenty Victory was held.

In order to ensure the successful completion of the major aerospace engineering support tasks and strictly implement the requirements of the group company and the institute for the recent scientific research and production tasks, the Beijing Institute of Aerospace Experiment Technology has deployed in advance, planned ahead, and coordinated resources such as materials, manpower, and equipment. During the peak period of model research and production tasks, President Wang Wanjun, Deputy Secretary of the Party Committee of Yue Wenlong, Vice President Wang Weidong and other leaders of the institute visited the site to guide the commissioning work. Faced with problems such as large resource conflicts and strong plan rigidity, with the support and deployment of the leadership of the Beijing Aerospace Experiment Technology Research Institute, the competent authority began to prepare and plan the ultra-conventional liquid hydrogen supply guarantee plan more than two months in advance, and started the independent research and development by the institute. The domestic (2 tons/day) hydrogen liquefaction equipment was commissioned and produced 534.3 cubic meters of liquid hydrogen in the month, providing fuel guarantee for the test task of the three-type hydrogen-oxygen engine.

At the same time, in the face of high-density test requirements, the test teams of various models quickly entered the “battle” state, handed over and carried out the adaptive transformation and testing of the test system in parallel, and gave full play to internal cooperation to solve test difficulties and neck problems. Special meetings were held. Sort out the test process and re-engineer the test process, strengthen the quality control and risk control measures and emergency response plans during the test preparation process, to ensure that the test preparation links of each model are foolproof, shorten the test cycle and improve the test ability, and played a continuous victory. good news. In the follow-up, the model development and test team of the research institute will be determined to pursue “first-class work”, “first-class process” and “first-class results”, continue to improve test capabilities, accelerate the realization of the “three highs” of model scientific research and production, and make new achievements for the construction of a strong aerospace country. contribution!
