On the Week of 17th June 2024 China Aerospace Science and Technology has completed the joint test of the 85-ton kerosene engine in full flight conditions.

Recently, China Aerospace Science and Technology has completed the joint test of the 85-ton liquid oxygen-kerosene engine and servo matching in the first stage of the Lijian-2 liquid carrier rocket. The test engine is in a two-way swing state, which can meet the control requirements of a 6-degree swing circle. The swing test simulating the full-scale operation of the first stage during the test was successful, verifying the matching of the first-stage engine of the Lijian-2 and the servo system, and obtaining key data such as the dynamic swing characteristics of the engine. At the same time, this test tested the first flight state of the first-stage engine of the Lijian-2.


This test assessed the two-way swing performance of the first-stage engine of the Lijian-2 and verified the working coordination of the servo control system and the engine. In the future, the engine will continue to carry out life test on this basis.
Lijian-2 adopts a CBC configuration, with a universal core stage diameter of 3.35 meters, a total length of 53 meters, a take-off weight of 625 tons, and a take-off thrust of 766 tons. The SSO carrying capacity is 8 tons, and the LEO carrying capacity is 12 tons. It is scheduled to fly for the first time in 2025…

[The joint test of the 85-ton liquid oxygen-kerosene engine YF-102 and servo matching flight conditions of the first stage of the Lijian-2 liquid carrier rocket of China Aerospace Science and Technology was successfully completed]

Recently, China Aerospace Science and Technology completed the joint test of the 85-ton liquid oxygen-kerosene engine and servo matching flight conditions of the first stage of the Lijian-2 liquid carrier rocket. The test engine is in a two-way swing state and can meet the 6-degree swing circle control requirements. The swing test simulating the full-scale operation of the first stage during the test process was successful, verifying the matching of the first stage engine of the Lijian-2 with the servo system, and obtaining key data such as the dynamic swing characteristics of the engine. At the same time, this test tested the first flight state of the first stage engine of the Lijian-2.


This test simulated the process of increasing the oxidizer and fuel inlet pressure caused by the flight overload of the first stage engine of the Lijian-2 by changing the engine inlet pressure. The engine thrust and specific impulse met the overall design requirements, the engine parameters were stable, and the performance indicators such as the oxygen self-pressurization met the design requirements.



During the test run, the engine extreme swing angle test, small swing angle joint training, load calibration, pressurized cold swing test, hot test combined swing test, etc. were carried out successively. During the ignition process, various waveform conditions such as square wave, triangle wave, and sine wave were tested. The maximum swing angle of the engine was 6°, and the servo feedback position and command tracking were good. The two-way swing performance of the first-stage engine of Lijian No. 2 was assessed, and the coordination between the servo control system and the engine was verified. Later, the engine will continue to carry out life survey tests on this basis.

Combined with this engine test run, liquid oxygen circuit immersion precooling, small flow precooling and large flow precooling tests were carried out simultaneously to obtain more accurate engine precooling characteristics and verify the correctness of the rocket body precooling scheme. In

addition, the low-order modal characteristics of the first-stage engine were obtained through structural modal tests of the installation process pull rod state and the installation servo mechanism state, providing important data support for the design of the attitude control system on the rocket. Environmental measurement points were added nearby to obtain environmental parameters such as noise.

[Zhongke Aerospace Pulsating Production Model Lijian-1 Y4 Launch Vehicle Completes Final Assembly and Testing] Recently, Lijian-1 Y4 launch vehicle completed the final assembly and testing as scheduled at the Zhongke Aerospace Industrialization Base and successfully passed the factory review. Factory delivery conditions are met. This time is an example of starting a new chapter in the pulsating production model in an industrialized base and applying parallel assembly of multiple rockets. It fully verifies the leanness, standardization and mass production of rockets under the pulsating production model.

During the final assembly work of the Lijian-1 Yao-4 launch vehicle, based on the existing production process optimization basis, the task of starting the final assembly test of the Yao-4 and Yao-5 rockets in parallel was completed. At the same time, the Yaosi-4 Star-Arrow joint Operation test, satellite and rocket modal test, satellite and rocket separation test. The two rockets are located at different pulse production sites, and production resources are cleverly deployed at different production rhythm sites. On the one hand, it significantly improves the efficiency of production resource use, and on the other hand, it de-tasks rocket production and manufacturing. A solid foundation was laid.

In terms of process flow, technicians completed the relatively cumbersome process in the final assembly and testing phase, effectively reducing the final assembly workload at the launch site and facilitating the requirements for batch storage, rolling backup, and real-time launch during high-density launch periods. In terms of quality control, based on the accumulated successful practical experience of previous multiple missions, technical details have been continuously improved to form a complete closed-loop system for recording, monitoring, and tracking the entire process to ensure the traceability of the entire quality life cycle. Under the requirements of ensuring innovation in the production model and continuously improving product reliability, the final assembly of the Lijian 1 Yao 4 and Yao 5 launch vehicles was completed ahead of schedule. The final assembly of the Lijian 1 Yao 4 launch vehicle took 25 days, which was longer than the previous period. The speed of one-shot rocket assembly has increased again!

Under the pulsating production mode, the Lijian-1 Yao-6, Yao-7, and Yao-8 launch vehicles are carrying out mass production and final assembly in an orderly manner. The products, equipment, instruments, tooling, etc. involved in the entire process have been planned in advance.
