LandSpace 蓝箭航天 One of sixty Chinese private space Carrier Rocket Companies in China-People’s Republic of China… On the occasion of the centenary of the founding of the party, the first phase of the Jiaxing LandSpace Blue Arrow Aerospace Center, located in VIC International Plaza, No. 13 Ronghua South Road, Yizhuang Economic and Technological Development Zone, Beijing China – People’s Republic of China…. The company located in a gathering place for the aerospace industry chain laid out in Zhejiang, was completed and will soon be put into use. Established mass production capacity for medium and large rockets, and completed the first phase of Jiaxing Blue Arrow Space Center…. Blue Arrow Aerospace Technology Co., Ltd. (Blue Arrow Aerospace) is a leading domestic commercial company for the creation and operation of aerospace transportation systems, established in June 2015, a national high-tech enterprise, Member of the International Astronautical Federation (IAF). Guided by the national strategy and guided by market demand, Blue Arrow Aerospace is committed to developing a series of medium and large launch vehicles with liquid oxygen methane as propellant, providing cost-effective and highly reliable launch services for the global market.
On the week on 19th October 2022 LandSpace 蓝箭航天 Recently, the “Tianque” vacuum liquid oxygen methane engine (TQ-15A) successfully completed the first full-system hot test run in Huzhou. The test lasted for 20 seconds. During the test, the engine started and shut down normally and worked smoothly.
TQ-15A is currently the vacuum type liquid oxygen methane engine with the largest thrust in China, with a vacuum thrust of 836kN. It is the secondary main engine of the second batch of Suzaku-2 rocket, and the layout plan of the existing 80t+10t secondary engine In comparison, the swimming engine TQ-11 was canceled, and the main engine was changed from non-swinging to pumping front-swinging, which reduced the complexity of the secondary engine system, reduced the total weight by about 400kg, and further increased the nozzle area ratio in the thrust chamber. The turbine exhaust is introduced into the large nozzle of the thrust chamber for cooling, which solves the problem of interference force caused by the turbine exhaust. The vacuum thrust of the TQ-15A engine is increased by 9%, the vacuum specific impulse is increased by 130m/s, the thrust adjustment range is expanded to 55%~110%, and it has the ability to start three times, which can greatly improve the adaptability of rocket launch tasks.
This TQ-15A engine is in a state with a servo mechanism without a large nozzle. This test run focuses on assessing the feasibility of the engine system, final assembly and improvement plans for each assembly, verifying the correctness of the start and shutdown sequence, and obtaining the measured performance data of the engine. and working characteristics. The engine starts and shuts down according to the predetermined program, works smoothly, and achieves the expected design goal.
This round of test runs is planned to carry out 5 tests (including two multiple starts), with a cumulative test time of 970 seconds. After the first test run, the long-range working reliability of the engine, the work adaptability during large-scale thrust adjustment, the engine and servo system will continue to be assessed. It can fully verify the engine design scheme and obtain the performance data of the engine under the condition of large nozzle.
Since the launch of the Suzaku-2 launch vehicle in September 2017, the research and development of the first batch of rocket technology status has been completed. At present, the Suzaku-2 Y1 rocket has left the factory and completed the low-temperature refuelling joint training. The final assembly of the Y2 rocket is being carried out at the Jiaxing Blue Arrow Space Center. On this basis, the company’s R&D team has carried out development iterations and optimization improvements on the second batch of rockets, so that they have better performance and higher reliability…
