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
