In this regard, Wang Bin and the government have given positive responses. After all, if their company successfully test flew the aerial plane, it is definitely a great progress for the whole human civilization. It also means that human civilization can successfully manufacture the aerial plane without the help of Wang Bin.


    So early in the morning of the atmospheric test flight of the X space company''s space shuttle, which they named challenger.


    Wang Bin, Jin Lao and other senior executives of Tiangong technology took a phoenix-1 super high speed airliner of Tiangong technology to the Aerospace Industrial Zone in the bald eagle desert, the aerospace aircraft manufacturing and test flight base of X aerospace company, and met Mr. mark, the person in charge of X aerospace company.


    At the same time, as soon as Wang Bin and his colleagues got off the plane, he saw the official plane landing on another runway.


    The official who came to participate in the test flight is also an old acquaintance of Wang Bin and the head of the official space agency, Qin Lao.


    Wang Bin was not surprised. After all, the test flight of X aerospace company is of great significance to the whole human civilization.


    Although it is said that once x aerospace company successfully tests the space shuttle, it will break Wang Bin''s monopoly in the manufacturing and production of medium and large space shuttles.


    This will make Tiangong technology a strong competitor in this field in the future. Even Wang Bin can be sure that even the X aerospace company''s space shuttle has many fatal defects and will definitely be bought by many people.


    Because although the current human civilization has found the existence of extraterrestrial civilization and threatened the security of the whole human civilization, there is unprecedented unity among the whole human civilization at this time.


    However, many factors cannot be eliminated in a short time, especially the long-standing ideas. At the same time, the whole human civilization must compete with each other. Only by competing with each other can we develop more and more advanced products.


    Take the X aerospace company for example. In order to break the monopoly of Tiangong technology, Wang Bin clearly knows how much time, energy and money they have spent in the past three years.


    If before the emergence of Tiangong technology, if anyone asked their company to spend so much time, energy and money to build an aerospace plane, their company could not agree at all.


    At the same time, Wang Bin also knows that with the X aerospace company manufacturing this space shuttle, regardless of the flight test results, it will certainly stimulate more people to invest in this area on a larger scale, and then there will be a second, a third or even more institutions with the ability to develop and manufacture space shuttles.


    For these situations, neither Wang Bin nor Tiangong technology intervened. After all, with the details of today''s Tiangong technology, if Tiangong technology really intervened, these companies could not successfully develop this aerospace aircraft.


    Although the emergence of these companies will damage the interests of Tiangong technology in this regard.


    But in fact, it is not. With the rapid development of Tiangong technology in controllable nuclear fusion technology and ion engine technology, Tiangong technology has begun to change its focus.


    In the past, the production and R & D of small and medium-sized aerospace aircraft was indeed the most important part of many core interests of Tiangong technology. Once there were problems, it would affect the next layout and R & D of Tiangong technology.


    However, after three years of precipitation, the research and development of super large aerospace aircraft has been successful, and the construction of real spacecraft has begun. Therefore, their aerospace technology has focused on the research, development and manufacturing of super large aerospace aircraft and real spacecraft.


    In fact, this is also the reason why Tiangong technology provided design drawings and materials to official space agencies before. After all, once the center of Tiangong technology is transferred, someone is bound to accept this huge market in the production of small and medium-sized aerospace aircraft.


    So, instead of taking advantage of outsiders, it''s better to take advantage of your own people.


    Even in the future, other space agencies in the world have successfully developed their own aerospace aircraft and aerospace aircraft engines, which can occupy a place in the market, but there will definitely be a big gap compared with Tiangong technology and the officials who obtain Tiangong technology.


    While Wang Bin was thinking about this, after a series of preparations, the X space company, the Challenger space shuttle, finally completed the final inspection and it was time to take off.


    So Wang Bin and they all stopped chatting, and everyone looked at the overhead plane.


    At this time, the ground crew around the aircraft began to evacuate one after another.


    When everyone was evacuated, the crew of the plane finally sent a take-off request to the tower.


    Naturally, the tower immediately agreed to their request.


    Then, the plane began to slide slowly in the eyes of Wang Bin and others, and the speed became faster and faster, and finally soared to the sky.


    In this regard, there is no accident on Wang Bin''s face. After all, they already have enough experience and data in the research and development of aircraft and engines in the atmosphere. The probability of failure is very small. If they fail. That''s strange.


    But when the speed of the plane reached the speed of sound, Wang Bin looked serious and worried on his face.


    This scene was just seen by mark, the president of X aerospace company.


    So a happy smile suddenly appeared on Mark''s face.


    However, if anyone knows what Wang Bin and mark think, he will definitely tell mark that he is wrong.


    In Mark''s eyes, the reason why Wang Bin is like this is that with the successful test flight of their x aerospace company''s space shuttle, it indicates that they have broken the monopoly of Tiangong technology in this field and threatened the authority of Tiangong technology in this field. Therefore, Wang Bin is like this.


    But in fact, this is not what Wang Bin thinks at all. The reason why Wang Bin is very serious on his face is that as the boss of Tiangong technology, he knows very well how much danger there is once the aircraft enters the ultra-high speed state.


    At this time, the speed of the space plane finally reached Mach 2. At the same time, the fuel inside the plane is also being consumed fiercely.


    Mach 2.5, Mach 3.0, Mach 3.5 and Mach 3.9. When the speed of the aircraft reaches Mach 4.0, the aircraft finally stops accelerating, because the variable cycle engine on their aircraft is not a pulse detonation engine, which can only provide the aircraft with a speed of about Mach 4 at most. Once the speed exceeds mach 4, the power of the aircraft engine will decrease linearly, In the end, it''s all about motivation.


    Of course, when the speed of the aircraft exceeds Mach 4, the altitude of the aircraft has reached 40000 meters, that is, 40 kilometers, but even so, the variable cycle engine of the aircraft has not stopped running.


    It can be seen from here that the variable cycle engine developed by X company is not good for nothing.
