Beijing Zhongke Aerospace Exploration Technology Co., Ltd. is the first domestic aerospace enterprise with mixed ownership, and it is also the target enterprise that Oriental Aerospace Port focuses on introducing. Relying on the scientific research strength and resource advantages of the Institute of Mechanics of the Chinese Academy of Sciences and the Aerospace Flight Technology Center of the Chinese Academy of Sciences, China Aerospace Science and Technology has been committed to the research and development and integration of space technology and aerospace vehicles as a platform for the transformation of major national scientific research projects, as well as the transformation and provision of technological achievements. Aerospace launch service. The Lijian-1 rocket project also adds a brand-new name card to the Oriental Space Port, which will surely promote the construction of the Oriental Space Port to take a solid step forward.
The test run of the second stage propulsion system of the Lijian-2 liquid carrier rocket was carried out at the Liquid Propulsion System Test Center of the China Science and Technology Aerospace Corporation, and the test run mission was a complete success. This test run is another major ground test before the Lijian-2 enters the flight test phase, marking that all large-scale ground tests of the propulsion system in the development phase of the Lijian-2 project have been successfully completed and the conditions for entering the flight test phase have been met
Recently, the test run of the second-stage power system of the Lijian-2 liquid carrier rocket was carried out at the China Aerospace Liquid Power System Test Center, and the test run mission was a complete success. This test run is another major ground test before the Lijian-2 transitions to the flight test stage, marking that all large-scale ground tests of the power system in the development stage of the Lijian-2 project have been successfully completed, and the conditions for transitioning to the flight test stage have been met.
In this test run, the filling and ignition sequence completely simulated the flight test conditions. Before the engine ignition, it successively experienced kerosene filling, supercooled liquid oxygen filling, pre-launch pressurization and pre-cooling, and simulated first-stage flight segments. The power system completed the first ignition, shutdown, taxiing, secondary ignition, shutdown and other actions according to the predetermined procedure. During the ignition process, the engine swayed in both directions, and the working conditions covered the flight mission profile. The parameters of each system changed steadily and were within the expected deviation range. The inspection after the test run showed that the rocket body structure was intact and the pressurization and delivery system had good air tightness.
The successful test fully verified the coordination and matching of the interfaces between the power, structure, avionics and other systems on the second stage of the rocket, effectively assessed the supercooled liquid oxygen filling and discharge process, intermittent discharge precooling, and secondary start-up of the power system, and obtained more accurate power and thermal environment data.
Now, we are one step closer to the first flight of Lijian II
