Chapter 386 Moon Satellite
Of course, due to the many functions of this satellite, there are a lot of scientific research verification projects to be carried out, so the weight of this satellite is naturally a lot, the weight of this satellite has reached as much as 12 tons. At present, they Tiangong Technology Except for the similarly manufactured No. 5 rocket, there is no rocket at all that can put this satellite into the Earth-Moon transfer orbit. Even the current Tiangong-4 rocket cannot put such a heavy satellite into it. Earth-moon transfer orbit.
Although the total weight of the Tiangong-4 rocket has reached 800 tons, it is already the largest official rocket, and its total weight is almost the same, but because of the Tiangong-4 rocket, it is a recyclable rocket. A type of rocket, so its carrying capacity is much lower than that of the same type of rocket, so it can’t be used for this launch mission at all.
Fortunately, their Tiangong-5 rocket has now been manufactured and can also put this satellite into the Earth-Moon transfer orbit.
Of course, like the Tiangong-4 rocket, the Tiangong-5 rocket is also a recoverable rocket, but unlike the previous recoverable rockets, the Tiangong-5 rocket is the last first-level rocket. It is not a traditional liquid hydrogen liquid oxygen rocket engine, but a Hundred-KN atomic engine developed by Tiangong Technology.
After all, the atomic engine does not need liquid oxygen for combustion, as long as there is liquid fuel. This makes Tiangong Technology very optimistic about this engine, and also very optimistic about the future of this engine. .
In fact, this atomic engine technology is also a technology purchased by Wang Bin from the Science and Technology Mall. Its prototype technology is Kanxing’s “sub-nervous” atomic rocket engine.
The prototype of this engine, that is, the thrust of the “sub-neural” atomic rocket engine, is only 60 kN. After the improvement and development of Tiangong Technology’s R&D personnel, this 100 kN atomic rocket engine was developed.
Like the previous prototype “sub-neural” atomic rocket engine, the weight of this atomic engine is much heavier than ordinary liquid hydrogen and liquid oxygen engines. Let alone other, it is now developed by Tiangong Technology. This atomic rocket engine has a thrust of only about 100 kilonewtons, which is 10 tons, but its own weight has reached nearly five tons, which is definitely several times that of other rocket engines of the same thrust.
But its specific impulse is much larger than that of liquid hydrogen and liquid oxygen engines, far from being comparable to liquid hydrogen and liquid oxygen engines, so this can make this first-level rocket store more fuel and make the rocket Send heavier objects into higher orbits and recover this first-level rocket.
This first-level rocket, after sending the satellite into the Earth-Moon transfer orbit, it must have enough fuel to return, but if you use an ordinary rocket engine, that is, a liquid hydrogen, liquid oxygen rocket engine, etc., it must be carried. More fuel will do. After all, to send the spacecraft into the Earth-Moon transfer orbit, the speed must be at least 11 kilometers per second.
But when the satellite needs to be returned to the rocket, the speed of the rocket must be reduced again. At this time, the rocket engine is needed to complete it. If the liquid hydrogen and liquid oxygen engine is used, a large amount of it must be carried. Fuel, in this way, the carrying capacity of the rocket will be greatly reduced, and can only reach a carrying capacity of less than 10 tons. This is definitely not the structure that Tiangong Technology wants to see.
If this is the case, then Wang Bin and the others might as well not reclaim the last first-level rocket!
Fortunately, with the atomic rocket engine, since liquid oxygen is not required as an oxidant, although the engine has a heavier weight, the overall weight of the first-level can be reduced to the level that Tiangong Technology can bear.
It can be said that the Tiangong-5 rocket uses many new technologies of Tiangong Technology. At the same time, the satellite launched this time is an aggregator of many key advanced technologies of Tiangong Technology.
Therefore, it took Wang Bin and the others a full month to design and manufacture this satellite. At the same time, the Tiangong-5 rocket has already been manufactured, but because the satellite has not been manufactured yet, so this paragraph At the time, the No. 5 rocket was not launched.
However, with the completion of the satellite manufacturing, the launch of the rocket is also on the agenda.
Of course, Wang Bin and his tiangong technology have also reported to their superiors regarding the upcoming launch of a communications satellite for lunar exploration by Tiangong Technology, and they have also obtained their approval.
And when the superior department received the application report submitted by Tiangong Technology, it also paid great attention to this. At the same time, it also attached great importance to the latest technology of Tiangong Technology. After all, the technology used on the rocket, this satellite , Both are the world’s top technology.
Therefore, in order to improve national self-confidence, the government has also carried out large-scale publicity on this. After all, the moon exploration satellite launched this time was not launched by the official space agency, but by the domestic private space company.
The most important thing is that the rockets and satellites launched this time are completely developed by Tiangong Technology itself, and are not officially provided and supported by technology.
And in the publicity, the official also clearly stated that the latest communication methods developed by Tiangong Technology were used in this satellite, and its technology feasibility at ultra-long distances was verified.
Therefore, once this news was officially announced, it caused a huge response throughout the country and even the world.
After all, it was a domestic private aerospace company that launched the moon satellite this time! Not an official aerospace company.
You must know that even the most advanced private aerospace company in the world before, X Aerospace Corporation, although it has many plans, including the moon project and so on.
But in fact at this time, apart from launching their company’s Starlink project and launching some earth satellites, their plans for lunar exploration and landing on the moon have not yet been launched. At this time, they are vigorously stepping up their company’s interstellar spacecraft. Flight test and test improvement project.
But now, their company hasn’t even built a spacecraft, and some people want them to start the moon project first. How can this make them able to receive it.
Therefore, the news that Tiangong Technology is about to launch a lunar satellite, once officially disclosed, aroused great attention from company x, and its person in charge immediately announced that their company will also launch a lunar satellite in the near future, The landforms were collected to lay the foundation for their company’s upcoming lunar project.
At the same time, because of the official publicity on the Internet, it has aroused heated discussion.
After all, this matter is sensational. You must know that before this, although Tiangong Technology would launch a rocket once or twice a month, and the rockets it launched were very successful, it did not appear. In an accident, the most important thing was that the company’s rocket was successfully recycled every time. Therefore, in the eyes of many people, Tiangong Technology’s rocket technology has reached or surpassed the level of X company.
