Soon, the design came to their rocket engine laboratory of Tiangong technology.


    "Mr. Sun, how''s the development of our new rocket engine?" after coming to the laboratory, Wang Bin immediately found the busy Mr. Sun and asked him.


    "Mr. Wang, you are here. The research and development of the new rocket engine is advancing in an orderly manner. Moreover, with the technical data provided by Mr. Wang and the achievements of Tiangong technology in materials, we have not encountered any major problems.


    However, as you know, Mr. Wang, since the supercomputer of our company, that is, supercomputing, has not been completed so far, and the existing computers in the company can no longer meet the calculation of our company, it is still a little slow in data calculation.


    But when the supercomputing manufacturing of our company is completed, there will be no problems in this regard, "Sun replied.


    In terms of rocket engines, with various technical materials provided by Wang Bin, Tiangong technology has made rapid progress in engine R & D. the 500 ton rocket engine has been successfully developed as early as before. The previously launched tiangong-4 rocket core stage main propulsion to rocket engine is the 500 ton rocket engine using Tiangong technology.


    Now, the thrust of the rocket engine they are developing is naturally greater, reaching the 800 ton level, and the fuel used is hydrogen and oxygen fuel. If this rocket engine can also be developed successfully this time, sun and they will challenge higher thrust rocket engines, that is, 1000 ton and 1500 ton rocket engines.


    Of course, both Wang Bin and sun Lao are full of confidence in this. They do not think that the 800 ton engine they have developed and above will fail.


    Subsequently, sun Lao took Wang Bin to check the progress of various projects in the rocket engine laboratory, and finally came to the R & D working group of 800 ton rocket engine.


    However, when Wang Bin came to the 800 ton rocket R & D team, he found that in the middle of the laboratory, there was a giant he had never seen before.


    Yes, this behemoth is the prototype of the 800 ton rocket engine developed by their 800 ton rocket engine research and development team of Tiangong technology, or a model engine is more appropriate.


    However, as like as two peas, the eight hundred tonnage rocket engine is only a prototype model, but the internal structure of the engine is even the same as that of a real rocket engine in many materials, and even if the engine is mounted on a real rocket, it will definitely be launched.


    But the model is a model after all, although there are many materials. They are all as like as two peas, but there are still many materials that are not real engine materials, because many of the materials inside the rocket engine are very expensive, and they are absolutely useless if they are used on the engine models.


    Therefore, although the engine can also be ignited or even work, its working time can only last more than ten seconds due to the limitation of internal materials. Once the time exceeds ten seconds, many parts inside the engine will be melted by the high temperature and high pressure generated by the rocket engine.


    As like as two peas, the engine is a prototype of a new eight hundred ton rocket engine, and it is also a rocket engine model of one to one, both inside and outside, which is exactly the same as the real engine.


    The purpose of making this model engine is to verify whether the basic design data of our engine are correct. If the verification is good, then we will start to manufacture a real 800 ton rocket engine. At the same time, we will also start to design rockets with larger tonnage and higher carrying capacity, "Sun said.


    Wang Bin nodded and looked at the rocket engine carefully.


    He found that this 800 ton rocket engine was very different from the 800 ton rocket engine he had provided to sun Lao before.


    The first is the nozzle of the engine. Although the size of the engine is consistent with the technical engine provided by him, the material of the engine is much thinner in terms of the thickness of the nozzle material. In addition, the material of the engine itself is much thinner than the technical data provided by him before, so the thickness of the engine itself The tonnage is definitely much lighter than the information he provided.


    Secondly, outside the nozzle of the engine, Wang Bin can clearly see that there are many coils made of superconducting materials wound on them, and on these coils, there are many equipment and structures that Wang Bin does not know.


    However, although sun Lao and others did not tell Wang Bin the role of these coils, Wang Bin also guessed that the role of these coils is to effectively protect the nozzle of the rocket engine so that its internal temperature can reach a higher level. At the same time, the running time of the engine is longer under the same material.


    In addition, Wang Bin also found that many structures on the engine did not directly copy the technology provided by Wang Bin, but combined with their own technology, which made Wang Bin very satisfied.


    "Sun Lao! Now that the prototype of this rocket engine has been manufactured, it must be possible to start manufacturing a real prototype!" Wang Bin asked.


    "Yes, our R & D personnel have completed the accounting of various data of this rocket, and are now preparing to manufacture the first real prototype. If everything goes well, the first prototype of our engine can be manufactured in less than a month," Sun said.


    "Very good!" Wang Bin nodded.


    Then they were in the laboratory. After watching for a while, sun Lao and Wang Bin came to the new concept engine R & D area. There are three laboratories here, namely pulse detonation engine laboratory, atomic engine laboratory and ion engine laboratory.


    As for the nuclear power rocket engine laboratory, it is not here, but on the third underground floor of their Tiangong science and technology rocket engine laboratory, and various safety facilities in the R & D area are in place. Security guards are watching 24 hours.


    At the same time, few people in Tiangong technology and the laboratory know the existence of this project. Except Wang Bin and sun Lao, only military representatives of the military know the existence of this project.


    After all, this project is very important for both Tiangong technology itself and the government. As long as Tiangong technology can make a breakthrough in nuclear power engines, the cost of rocket launch will be reduced again, even to 10000 yuan per ton.


    In terms of carrying capacity, as long as nuclear rockets are developed, it will be very easy to send hundreds of tons of things into space
