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, 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….
“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.
Carrier Rocket viewing Looking This is how LandSpace we make rocket engines
How are rocket engines made and tested? How do thousands of parts magically turn into giant rocket bodies? How do we put a satellite into a predetermined orbit? What are some of these little-known secrets? The popular science series of “Arrow Watching Characters” exclusively reveals the daily work of Blue Arrow Aerospace! In this issue, we will follow a technical master to visit the Blue Arrow Aerospace Intelligent Manufacturing Base in Huzhou, Zhejiang, and see how the first domestic 100-ton thrust liquid oxygen methane engine is produced. In the next issue, we’ll take a look at what the engine has to go through before it’s ready to go on a journey to space
