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…

“Tianque” vacuum engine TQ-15A completed the final assembly…

On September 25, 2022, the “Tianque” family vacuum liquid oxygen methane engine-TQ-15A completed the first assembly at the Huzhou Intelligent Manufacturing Base, and is scheduled to be completed on 10 on the 8th September 2022 it was delivered to the test bench for test run assessment and analysis..

The TQ-15A will be put into use as the second batch of secondary main engines of the Suzaku-2 Carrier Rocket. The engine and TQ-12A general-purpose turbo pump, valve, gas generator and other key components adopt the pump front swing scheme, the vacuum thrust reaches 836kN, and it can achieve 60%~110% depth variable thrust, and the overall performance has reached the international advanced level.



Compared with the second-stage engine of the Suzaku-2 rocket in service, its advantages are:

– Cancellation of the traveling aircraft, reducing the system complexity and reducing the weight by about 400kg;
– With ±4° two-way swing function, the attitude can be carried out without the traveling aircraft control;
– It has the functions of three times of ignition and depth change, which can meet various ballistic requirements;
– The use of the pump front swing layout scheme reduces the pump-push distance and improves the compactness of the structure;
– The turbine pump uses the face sealing technology to reduce the Small leak rate simplifies the rocket launch process;
– The turbo pump is changed to a two-stage turbine, which improves efficiency and reduces the size of the engine;
– The turbine exhaust is introduced into the extension of the thrust chamber nozzle, which improves the specific impulse performance of the engine and reduces the size of the engine. Engine side force.

In the future, with the application of the TQ-15A, the cost of the Suzaku-2 carrier rocket will be reduced and the capacity will be further improved to meet more types of launch needs and meet the requirements of the commercial development of future launch vehicles.

Remarks: The TQ-15A engine in the picture is in the state without the large nozzle.

Established mass production capacity for medium and large rockets, and completed the first phase of Jiaxing Blue Arrow Space Center

Jiaxing LandSpace Blue Arrow Aerospace Center is located in the Aerospace Industry Park of Jiaxing City, Zhejiang Province China, and People ’s Republic of China. It aims to build a top aerospace industry base in the entire industry chain that integrates design simulation, testing and testing, and intelligent manufacturing.

Blue Arrow Aerospace Tianque 80-ton improved engine completed the second start test After working for 10s, the engine started and shut down normally, with stable operation and stable performance. In addition, the mission profile of the taxiing section was simulated after one start, and the temperature change data of the propellant in the engine inlet and the pump cavity were obtained, in order to optimize the pressure of the propellant tank before the second start. and pre-cooling process to provide the basis.



The TQ-12A engine was established and developed in February 2021. On the basis of fully inheriting the TQ-12 engine technology, through design optimization and improvement, the engine thrust was increased by 9%, the specific impulse was increased by 40m/s, and the weight was reduced by 100kg.

The success of TQ-12A’s second start-up test indicates that Blue Arrow Aerospace’s “Tianque” series of liquid oxygen methane engines are fully reusable, effectively enhancing the launch capabilities of “Suzaku” series of launch vehicles for various mission orbital satellites, and Provides basic technical support for sub-level recycling requirements and reusability.


This round of test runs was carried out 6 times and the cumulative test run time was 900s. This round of test runs focused on the evaluation of the secondary starting capability of the engine, the feasibility of the engine and component improvement plan and the reliability of long-range work, and the working coordination between the engine and the overall controller, and verified The thrust regulation ability, working stability and thrust and mixing ratio control strategy of the engine in the range of 50%~110% are obtained.

As of July 31, 2022, Tianque’s 80-ton liquid oxygen methane engine has completed a total of 37 engine thermal test runs and flight calibration test runs, with a cumulative test run of more than 20,000 seconds.
