Development Progress | Deep Blue Aerospace completed the first fairing separation test in China using a non-pyrotechnic connection unlocking mechanism…
On the 2nd September 2023….. Recently, the separation test of the fairing of the “Xingyun-1” liquid recyclable and reusable launch vehicle of Shenlan Aerospace was a complete success. This is the first test in China to use a non-pyrotechnic connection unlocking mechanism to separate the fairing. In order to fully verify the separation state of the fairing under different deviations, Deep Blue Aerospace has carried out many experiments on this round, all of which use the self-developed non-pyrotechnic connection unlocking mechanism. The separation timing of the test is correct, which is basically consistent with the simulation results. No damage occurred.
This round of separation tests was completed at the Deep Blue Aerospace Nantong Rocket Assembly Base, and the fairing was completely recovered after multiple tests.
This round of separation tests was completed at the Deep Blue Aerospace Nantong Rocket Assembly Base, and the fairing was completely recovered after multiple tests.
This round of testing used the same set of connection and unlocking mechanisms to complete multiple separation tests within three days, verifying the reusability and rapid response capabilities of the self-developed non-pyrotechnical connection and unlocking mechanism. This is the first time in domestic fairing separation tests. This round of fairing separation test is one of the phased tests before the first flight of the “Nebula-1” liquid recyclable launch vehicle. The success of this round of test will lay the foundation for the successful first flight of the “Nebula-1” rocket in 2024. Solid foundation.
Why do rockets need to separate their Fairings?
The launch vehicle will encounter harsh environments during flight. The fairing protects the satellite payload from the aerodynamic forces and aerodynamic heat and also reduces the aerodynamic resistance of the launch vehicle during flight. After leaving the atmosphere, the launch vehicle is no longer affected by aerodynamics and throwing away the fairing helps to increase rockets capacity..

The current round of “Thunder-R1” engine and subsequent series of tests will accumulate a large amount of data for the power system test run, and will also be the first high-altitude vertical recovery flight test of the first sub-stage of the “Xingyun-1” rocket, and the first stage of orbit + recovery. Fly on a solid foundation. In the follow-up, the test station will continue to carry out the normalized test run assessment of the engine to ensure the smooth implementation of the vertical recovery test of the first sub-stage of the “Xingyun-1” rocket.
Deep Blue Aerospace’s new power test base has been put into use , and the advantages of the new test stand are prominent. “Thunder-R1” engine test live highlights. The performance of the assembly and other components has been improved, and a series of important optimization improvements have been made in the layout of the final assembly, creating a more solid power foundation for the vertical recovery and reuse of the rocket. During the test run, the engine was ignited, started, and shut down according to the predetermined procedures. The test process was in good condition, the measurement parameters were complete and accurate, and all indicators met the design requirements. The whole machine test run is an important means to assess the coordination of the various components of the engine and to obtain the working parameters of the engine in simulated real working conditions. This round of complete machine test run is the test bench test run of the new test bench of Shenlan Aerospace’s new power test base. Combining the completed components and semi-system test bench test run, the success of the test bench test marks the first vertical test bench of Deep Blue Aerospace. It has the ability to test the whole process of rocket engine development, which is an important milestone in the construction of the power test base.

The new version of the engine is tested and the new flight is ready to race against time
” Thunder-R1″ reusable engine is the first open-cycle liquid oxygen kerosene pintle engine in China, with a thrust adjustment capability of 30%~110%, following the principle of “redundant power system, industrialized low-cost manufacturing”, The “9+1” mode is adopted, that is, the first sub-stage of the rocket is connected with 9 basic engines in parallel, and the second sub-stage is equipped with a vacuum type engine, so as to send the payload of the rocket into the predetermined orbit and realize the vertical recovery of the first sub-stage.
In terms of general assembly layout, the new version of the “Thunder-R1” engine adopts the “pump back swing” method, which greatly reduces the engine swing moment in terms of swing angle and flexibility, significantly reduces the envelope size, and makes the layout more compact. The main components including combustion devices, turbo pumps, valves, etc. are all independently developed. The key components of the engine, such as thrust chambers, gas generators, turbo pumps, and large-diameter conduits, are manufactured using 3D printing additive manufacturing technology, which greatly reduces the number of engine components and effectively controls the influence of human factors in the production process, shortening the production process. the production cycle.
Through the bold use of new processes and adoption of new technologies, Deep Blue Aerospace has established a mass rapid production capacity of liquid rocket engines based on its own characteristics, and has achieved rapid iteration through continuous testing to feed back design and optimization improvements. It is the goal of Deep Blue Aerospace to establish a high-reliability, low-cost, and reusable liquid oxygen kerosene engine design, manufacturing, and testing of the entire process, which can effectively support the high-frequency, low-cost large-scale commercialization of launch vehicles. .
Next, Deep Blue Aerospace will carry out a series of tests such as the three-time ignition of the “Thunder-R1” engine, working condition deviation, and reliability verification, as well as a high-altitude vertical recovery flight test of the first sub-stage of the “Xingyun-1” rocket.
