Because at this altitude, if it is an ordinary aeroengine, it will strike long ago because of the problem of oxygen.


    Now, the variable cycle engine developed by X company is still working, and it seems that its maximum working height is more than yuan. It may even work even at the edge of the atmosphere.


    Therefore, Wang Bin is still optimistic about this kind of engine. If x aerospace company can really devote itself to research and development in the future, it will not take too long. It will only take ten or eight years. They will certainly be able to develop a variable cycle engine with space flight capability.


    While Wang Bin was thinking about this, the challenger of X aerospace company, the space shuttle, finally reached an altitude of 50000 meters. At the same time, the variable cycle engine on the aircraft finally stopped working at this altitude due to the lack of oxygen.


    Just when Wang Bin and everyone present thought that their test flight of this aerospace aircraft was likely to succeed, suddenly, a row of red data appeared on the big screen of the flight control center. At the same time, the alarm of the flight control center also sounded.


    "What''s the matter? If there''s a problem with the plane, contact the crew immediately." just when the alarm sounded, Mark''s smiling face suddenly changed wildly. After all, if the aerospace plane has a problem at this time, not only their company''s stock will be greatly affected, but also their company''s market value will be greatly damaged.


    At the same time, the safety of these crew members on the space plane will also be greatly threatened. You know, these astronauts on the plane are not ordinary astronauts. They are not only the best astronauts in their country, but also ordinary astronauts. They are the descendants of important personnel of some important multinational consortia, So nothing can happen.


    Even their x aerospace company, as the largest and most advanced aerospace company in the world except Tiangong technology and Huaxia, can''t provoke these people. Most importantly, these big chaebols are their x aerospace company and the largest investor. Once these people have problems, they can''t stand the Revenge of these chaebols.


    After all, this is a bald eagle, not Huaxia, so mark can''t help admiring Wang Bin and Tiangong technology.


    After all, if Wang Bin and their Tiangong technology were here, they would never have the opportunity to develop to such a scale. Once they developed to a certain extent, these chaebols would be like asking about bloody sharks and be divided up at the first time.


    "Report to the flight control center. This is the Challenger space plane. This is the Challenger space plane. Now we have a problem. Our plane''s No. 3 variable cycle engine is damaged due to the long-time operation of the engine and the friction generated by high speed. At this time, the engine can''t work at all, but fortunately, because of me At this time, our plane had broken through the atmosphere and entered space. There was no oxygen around, so the engine did not burn.


    In addition, due to the rapid speed of the aircraft when breaking through the atmosphere, our challenger''s tail rudder also lost its function. According to our inference, it is likely that the tail rudder has melted! "


    "What? The engine has a problem and the rudder can''t be used. How is this possible? You know, this variable cycle engine, but the results of our joint efforts, how can there be a problem?" Mark said incredulously when he heard the report from the plane.


    At the same time, he immediately asked the technicians present to analyze the data immediately, and the reason must be found out. After all, if the design data is used, such a problem is absolutely impossible.


    As for the tail wing of the aircraft, they have all done heat insulation and high temperature resistance treatment. In principle, such a problem should not occur.


    Of course, for them,. The most important thing now is to ensure the safety of the aircraft.


    According to the current situation of the aircraft, the aircraft will be pulled back to the earth under the action of the earth''s gravity in no more than ten minutes. However, in the current situation, the aircraft simply does not have the ability to re-enter the atmosphere. If it forcibly enters the atmosphere, the only structure is naturally aircraft destruction and human death.


    So he immediately said to the communication system: "the Challenger aerospace aircraft, immediately check the aircraft''s fuel system to see if it carries rocket fuel, that is, liquid hydrogen and liquid oxygen. I remember that in order to prevent accidents, this aircraft still carries certain rocket fuel."


    Subsequently, the crew immediately checked the fuel of the aerospace aircraft and found that, as their president said, there was indeed a lot of rocket fuel on board, enough for the aerospace aircraft to enter low earth orbit, which greatly relieved them.


    At the same time, these crew members also began to scold mark and the R & D personnel of X aerospace company.


    After all, the biggest responsibility for the accident lies with mark and the R & D personnel of X company.


    At the same time, they also began to check the pulse rocket of the aircraft. After all, this is not the pulse rocket engine of Tiangong technology. If it is the pulse engine produced by Tiangong technology, these crew members will not worry at all. After all, the quality of Tiangong technology''s products is obvious to all. Otherwise, since Tiangong technology produced the engine, Until now, I haven''t heard that there is a problem with the engine of Tiangong technology.


    However, the pulse rocket engine produced by X aerospace company is now equipped by Tiangong science and technology. How can they rest assured that the failure of the previous variable cycle engine is just around the corner.


    In fact, at the moment, these astronauts are really under great pressure. At the same time, they think that even if the engine on the overhead space plane is not the product of Tiangong technology, but the official product of China, they will not be so worried.


    Soon the inspection was completed. After all, there was not much time left for them at this time. There was only less than ten minutes. If they could not enter the orbit within ten minutes, the consequence would naturally be pulled back to the atmosphere by the gravity of the earth. Finally, they would burn everything in the atmosphere with the overhead space plane,


    In fact, even if their engine has problems, they can only start the pulse engine, because there is no better way at this time.


    After the inspection, the captain took a deep breath, and then ordered the crew: "everyone, go to heaven or hell, it depends on whether God will bless us. Now I order the plane to adjust its attitude and prepare to start the pulse engine!"
