Founded in 2015 located in Beijing ….天兵科技 – 北京天兵科技有限公司Tianbing Technology is an Aerospace propulsion system supplier and spacecraft provider One of Sixty Plus Chinese carrier Rocket companies in China, People’s Republic of China ……. Tianbing Technology is an advanced aerospace propulsion system supplier and aerospace vehicle provider. Tianbing Technology independently develops the next-generation ambient temperature green HCP liquid propellant and minimalist aerospace propulsion system. As an upgraded product of traditional chemical propulsion system, it can meet cost-effective aerospace. Advance system supporting needs. The next-generation green HCP aerospace propulsion system, first tested by Tianbing Technology, can be used in the small-vehicle main power and launch vehicle upper-level propulsion system.

[天龙三号Tianlong 3 plans to complete the first flight of the rocket in the first half of 2024] Recently, Tianbing Technology announced the completion of several hundred million yuan in C+ round financing, which will be used for the mass production of the Tianlong 2 medium-sized liquid rocket that successfully made its first flight, as well as the Tianlong 3 The development and first flight of large-scale liquid launch vehicles and engines, the research and testing of recyclable and reusable technology, the construction of Tianlong-3 dedicated launch stations, the construction of batch production capabilities and the improvement of talent teams.


The Tianlong-3 large liquid launch vehicle is tailor-made for the construction of my country’s satellite Internet infrastructure. Its product performance is benchmarked against the SpaceX Falcon 9 rocket. It has a diameter of 3.8m, a take-off mass of 590t, a LEO capacity of 17t, and an SSO capacity of 14t. It uses high thrust. , the reusable liquid rocket engine will be the first in China to achieve the capability of group shooting of more than 30 satellites in one rocket, meeting the “low-cost, high-reliability, and high-frequency” launch requirements of the satellite Internet. At present, the rocket has completed product design and production and is undergoing ground testing and verification. It is planned to complete the first flight of the rocket in the first half of 2024. Within three years after the first flight, it will have a commercial launch capability of more than 30 rounds per year..

The reporter learned from China Aerospace Science and Technology Group Co., Ltd. on July 23 that the main engine of my country’s manned moon landing rocket was tested in the Fengzhou Test Area of ​​the Sixth Academy of Aerospace Science and Technology Corporation, and achieved continuous success. This test run verified the engine flight mission profile, and provided strong support for the solidification of the engine technical state, the establishment of the product technical baseline, and the improvement of reliability.

The engine is the power source of the rocket, and its development process is very complicated. Test run is an important link in the engine development process, and there are dozens of types. In layman’s terms, engine test run is the process of igniting the engine and verifying the rationality of its design scheme and process reliability. This is an indispensable and important part of the development and delivery of a type 1 engine. It will run through all stages before and after engine development. Each stage of test run has different meanings, and the ignition time varies from a few seconds to hundreds of seconds.

It is reported that the engine used in this test run uses advanced liquid oxygen kerosene as fuel, which is improved and iterated from the high-thrust liquid oxygen kerosene engine used by the new generation of launch vehicles such as the Long March 5. The thrust reaches 130 tons. The R&D team of the Sixth Academy of Aerospace Science and Technology Group adheres to the concept of digital design, and has successively overcome key technical problems such as engine start-up and shutdown sequence, engine wide-range continuously variable thrust, and engine long life and high reliability.

In addition, the continuous success of the test run has fully verified the reliability of a number of new carrying process technologies. The engine production of this test run adopts the concept of intelligent manufacturing, and actively applies new materials, new processes, and new technologies. The inner wall of the thrust chamber of the core component adopts a new protective coating, key assemblies adopt automatic welding technology, and a large number of components adopt 3D printing technology.

During the preparation of the engine test run, the participants in the research and test conducted tests and verifications on each subsystem of the test through comprehensive means such as digital modelling, simulation calculation, and system debugging. The successful test run shows that the test area has greatly improved the multi-station parallel test run capability and test efficiency by optimizing the workflow.
