[The first stage of the Nebula-1 rocket of Deep Blue Aerospace has successfully completed the three-machine parallel full-time sequence power system series test. The first stage of the Nebula-1 rocket is about to undergo a VTVL high-altitude vertical recovery flight test]
On July 21, 2024, the Nebula-1 rocket (referred to as “Nebula-1”) independently developed by Deep Blue Aerospace completed the first stage three-machine parallel full-time sequence power system series test at the Deep Blue Jigang Test Base in Jinan City, and achieved complete success.
This test simulated the full working conditions of high-altitude recovery flight and a large range of engine variable thrust test. During the test, the first stage of the “Nebula-1” rocket also carried out verification of the system performance of locking, unlocking, and semi-deployment of landing legs and grid rudders in real vibration and thermal environments. After the test, the entire system including the engine, landing legs and grid rudders was inspected and confirmed to be in good condition.
After the test, the rocket body will go to the test site to prepare for the upcoming high-altitude vertical recovery flight test of the first stage of the “Nebula-1” rocket.
[China’s first 10-kilometer-class vertical take-off and landing flight test of a reusable carrier rocket was a complete success]
On June 23rd 2024, China’s first 10-kilometer-class vertical take-off and landing flight test of a reusable carrier rocket was a complete success. The rocket was developed by the Eighth Academy of China Aerospace Science and Technology Corporation.
At about 1300 hours Beijing Time, at the Jiuquan Satellite Launch Center, Inner Mongolia, China, People’s Republic of China , a 3.8-meter-diameter reusable carrier rocket new technology verification arrow was erected on the launch pad. Three variable thrust liquid oxygen-methane engines were ignited, spewing blue tail flames. The rocket body rose to an altitude of about 12 kilometers. The central engine adjusted the thrust, and the rocket descended in a controlled manner. At 50 meters from the ground, the four landing legs unfolded, and then the rocket slowly descended, approaching zero altitude, and landed steadily on the recovery field, achieving a fixed-point vertical soft landing.
This test is currently the largest-scale vertical take-off and landing flight test of a reusable carrier rocket in China, and it is also the first application of the domestically developed deep variable thrust liquid oxygen-methane engine in a 10-kilometer-class return flight. The entire test took about 6 minutes. The rocket went through five stages: accelerated ascent, decelerated ascent, accelerated descent, decelerated descent, and slow descent, achieving “take-off, accurate control, unfolding, and stable landing”.

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

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. Deployment, production tasks are clear, and production and assembly can be started simultaneously in the final assembly and testing plant and intelligent manufacturing plant. It is worth mentioning that the Zhongke Aerospace Industrialization Base currently has complete structural cabin manufacturing and assembly capabilities. Starting from the Lijian-1 Yao-5 launch vehicle, the manufactured cabins will be directly used and delivered for final assembly, further shortening the production and manufacturing cycle. .
