Although, at this time, many people are praying in their hearts, hoping that the test flight of the space plane can succeed, they forget that science is nothing else. If it is a small thing in daily life, praying, there may be miracles.


    However, science is not. In particular, a science and technology intensive product integrating the world''s top technology, such as aerospace aircraft, is rigorous. Any negligence may cause irreparable consequences.


    "Mr. mark, tell me the truth, how sure are you x aerospace company about the test flight of this space shuttle?" just as the offline ceremony was about to be completed and they were about to pull down the red cloth of the space shuttle, their official asked the general manager of X aerospace company again.


    In fact, in this case, the official has repeatedly asked the president of X aerospace company, but the answer is that their company is more than 90% sure of the test flight.


    However, mark, President of X aerospace company, made his face full of anxiety.


    "Sir, as this test flight is a subsonic test flight in the atmosphere, I have more than 80% confidence in the success of the test flight, but if this test flight is an atmospheric flight, to tell the truth, I have less than 50% confidence.


    But isn''t success based on failure? Even if it fails, so what? It won''t take long to rebuild an aircraft. After all, when our company developed the Starship before, we failed many times in a row in order to succeed. In the end, we haven''t succeeded yet! "Mark said indifferently.


    For Mark''s words, the official looked confused. At this time, he really had a lot to say in his heart.


    You should know that this is not a starship they developed before, but an aerospace plane. The most important thing is that at this time, there are their best astronauts inside the aerospace plane. If there is a problem with the aerospace plane, what should the astronauts do inside the aerospace plane, even if they have many means of escape, The astronaut may not survive. Most importantly, he doesn''t know whether these means of escape are useful or not.


    However, in the end, the official sighed and stopped saying anything. After all, mark, as a capitalist, especially a big capitalist with many assets, doesn''t care about these. For him, all these can be measured by money. All he needs is to prove to the world that his company, In other words, X aerospace company also has the ability to develop and manufacture aerospace aircraft engines.


    As long as the world knows this, their company''s shares can definitely rise significantly, and their company''s market value can naturally rise significantly, which is what he is most concerned about.


    It was he who knew clearly what mark was thinking at this time, so he stopped talking. After all, even if he was an official in this country, he was unable to change these.


    So he can only pray like others that the test flight can succeed.


    At this time, with the flash of a flash, he, mark and others finally pulled down the red cloth of the SkyPlane, and the SkyPlane finally revealed its true face to the world.


    When the appearance of the aerial plane was finally displayed in front of everyone, many people liked the appearance of the aerial plane very much.


    However, in fact, the shape of the aerial plane is indeed very beautiful. Even the shape of the aerial plane is very similar to the female Wushen plane they designed decades ago.


    At the same time, from the shape, it can be clearly seen that the wing of this space shuttle is also a variable wing design. It can be seen from here that x aerospace company is very attentive to the design of this space shuttle, but compared with the female warrior, the length and volume of this space shuttle are more huge, Even compared with the Phoenix II series of aerospace aircraft of Tiangong technology, it is even larger.


    After all, according to their design data, the total weight of this space plane is as high as more than 300 tons, and the carrying capacity of this space plane is also very amazing. It can send materials weighing about 40 tons into orbit below 1500 kilometers.


    If there is a refueling in space, there is absolutely no problem flying to the moon orbit.


    The reporters present were naturally very happy about the SkyPlane. Amid everyone''s praise, the SkyPlane was slowly pulled out of the frame by a tractor and came to their company''s airport runway to take off.


    Like the previous Tiangong technology, the aerospace aircraft of their company also needs to carry out a series of inspections before the flight test. Because the internal intelligence of the aircraft cannot be compared with that of Tiangong technology, the inspection time naturally needs to be longer.


    And because they basically use manual inspection, it is inevitable that some mistakes will occur. Therefore, in order to ensure that all inspections are in place, before the flight test, they must go through the inspection of ground service and aircraft manufacturing and design personnel for many times before taking off.


    It took four hours to complete the final inspection of the X aerospace company''s space shuttle. At this time, their space shuttle was finally ready for its first test flight.


    With the command from the tower, the aircraft''s engine finally began to turn.


    However, when the engine began to turn, many people present found that the sound of the engine was wrong, because the sound of the engine was not like that of a detonation pulse variable rocket engine, but like that of a turbofan engine when an ordinary plane took off.


    This makes many people very confused, but people familiar with the matter are different. They clearly know that it is not the pulse detonation rocket engine that powers the aircraft at this time, but the turbofan engine used by most aircraft in the atmosphere.


    Of course, as a real space plane, what is running on the space plane at this time is not the complete turbofan engine, but the variable cycle engine developed by them over the years.


    After all, for them, compared with the relatively unfamiliar pulse detonation engine, they are more mature in the field of turbofan engine and master the internal technology more thoroughly.


    Therefore, in order to ensure the safety of the aircraft flying in the atmosphere, the aerospace aircraft is powered by a variable cycle engine when flying in the atmosphere.
