Compared with the pulse detonation engine, which is unfamiliar to them, their company is more confident in this kind of more traditional engine, and they believe that the potential of variable cycle engine in the future is also very large, absolutely. Based on this, they have developed and produced their own aerospace aircraft engine.


    In this regard, the X Aerospace formula and the bald eagle are looking forward to it. Of course, it is not a simple thing to develop the aerospace aircraft engine based on this variable cycle engine. According to the inference of their company experts, it will take at least five to ten years.


    Therefore, according to the current situation, even after the successful test flight of their aircraft, the variable cycle engine on the aerospace aircraft can only be used in the atmosphere, and the pulse detonation rocket engine will be used as the power outside the atmosphere.


    At this time, after taxiing for nearly 3 kilometers, the huge plane finally pulled up its nose slowly.


    Although the weight of the aerial plane is very heavy, and the weight of oil and so on has reached four or five hundred tons, because the engine used by the aerial plane in the atmosphere is the high thrust variable cycle engine newly developed by their company, and the thrust in the atmosphere has reached more than 40 tons, so the ground taxiing distance of this aerial plane is very obvious when taking off, Compared with the Phoenix series of Tiangong technology, it is much shorter.


    However, after the plane took off, from the speed of the plane away, it is obvious that the acceleration speed of the overhead plane is far from being compared with the Phoenix series of Tiangong technology.


    After all, when the Phoenix series engine outputs the maximum power, the speed from zero to Mach 1 can take less than one minute. Of course, the premise must be that the personnel in the aircraft can withstand it.


    However, the speed of the space shuttle manufactured by X space company is much slower, and it takes at least three to five minutes to reach the sonic level.


    Although the SkyPlane is far from comparable to the Phoenix Series in terms of speed-up, the people at the airport, including the senior management of their company and official personnel, are full of smiles.


    The successful take-off of the first flight of the aircraft has a great morale boosting effect for them. A few minutes later, the overhead aircraft successfully landed on the airport runway, and the ground service and technicians on the ground naturally immediately carried out a series of inspections on the overhead aircraft.


    Because of the impact of the previous research and development of aerospace aircraft by paste technology, they are also preparing to conduct a second test flight of the aerospace aircraft in three days, and this test flight will not only carry out supersonic and hypersonic test flights.


    Even in order to show the strength of their company, they are going to fly in three days.


    However, the atmosphere boasting flight here does not mean that the aircraft is ready to fly in space in three days and let the overhead aircraft enter the earth''s low earth orbit. It is just ready to let the overhead aircraft fly directly out of the atmosphere at ultra-high speed of sound, turn off the variable cycle engine of the overhead aircraft, and do not start the pulse engine on the overhead aircraft, When the altitude of the space plane reaches the limit, let it return to the atmosphere, and finally start the engine to return to them.


    The purpose of doing so is to test the state of the overhead space plane when flying out of and re entering the atmosphere. After all, for an aerospace plane.


    Fly out of the atmosphere and re-enter the atmosphere. Data is very important.


    Although it is said that their company has also purchased several Phoenix series aerospace aircraft from Tiangong technology, and has driven these Phoenix series aerospace aircraft into and out of the atmosphere countless times, and has also recorded a large amount of data.


    However, these records are only the data records of Phoenix''s series of skydiving aircraft entering and leaving the atmosphere, which does not play a great reference role for their aerospace aircraft. After all, their aerospace aircraft is not a small aerospace aircraft. Their aerospace aircraft is the data required by a medium and large aerospace aircraft, which is naturally different.


    However, on the day when x aerospace company took off the production line and successfully tested the space shuttle, a large number of media all over the world reported it, saying that it was a breakthrough in the history of world aerospace, saying that they successfully broke the monopoly of Tiangong technology on the engine of the space shuttle, as well as the monopoly of Tiangong technology in the manufacturing of medium and large space shuttles, In short, these news reported and exaggerated this matter wantonly. As for this overhead day, some defects on the plane were not mentioned, as if they didn''t know it at all.


    Of course, not all reports praise the X space company''s space shuttle. In fact, many media in the world are not optimistic about the X space company''s space shuttle.


    Although before that, with the help of the pulse detonation rocket engine of Tiangong technology and other special parts of the space shuttle, such as the steering system of the space shuttle, the control system of the space shuttle, the remote communication system of the space shuttle and so on.


    In addition to Tiangong technology and Huaxia, it is the first in the world to achieve a breakthrough in aerospace aircraft manufacturing from scratch.


    But in fact, they don''t know much about the manufacturing of many parts of the space shuttle. Naturally, many people are not optimistic about this plane.


    Some people even ridiculed their company, saying that their company has not realized the ability to completely manufacture small aerospace aircraft.


    Now I want to completely independently manufacture medium and large aerospace aircraft, which is completely a dream.


    Of course, Wang Bing and Chinese officials are naturally very concerned about X aerospace company, the first aerospace plane independently developed by their company.


    At the same time, as the chief astronaut of Tiangong technology, Zhao Feng, although he was already in orbit in the earth, he also saw relevant news from the broadcasting system and network of the space station, communicated with the company and learned the details of the X space company''s overhead space shuttle.


    After reading the news and the company''s data, Zhao Feng frowned. As the chief astronaut of Tiangong technology, he naturally knew that the successful test flight of an aerospace plane in the atmosphere did not mean that the aerospace plane would be able to fly across the atmosphere.


    After all, flying in the atmosphere, because x aerospace company and other aerospace companies in the world have rich experience in the manufacturing of intra atmospheric aircraft, including the manufacturing of medium and large aircraft. Of course, they are familiar with the road, and there are no problems. Even if it is a super large intra atmospheric aircraft, for example, the volume is comparable to 225, The design and manufacture of super large aircraft are not a problem, but this is by no means applicable to the design and manufacture of aerospace aircraft.


    As an experienced astronaut, he clearly knows how dangerous the next test flight is for their aerial plane to fly across the atmosphere.
