For Wang Bin''s words, general Qiu certainly believes and expects very much. After all, an enterprise that can develop such an advanced engine from scratch is definitely not a simple enterprise. Its scientific research strength is absolutely strong. Even compared with some official R & D and production enterprises, it will never be worse or even better.


    Of course, Wang Bin is also very confident about this. First of all, his confidence naturally comes from the R & D team of Tiangong technology, because now their R & D team of Tiangong technology is not what it used to be, and second comes from the technology mall system.


    After all, even the engine developed by Tiangong technology is not advanced at all if it is put in the science and technology mall. Let alone all kinds of advanced engines in the world, only the kanxing series engines sold in the science and technology mall have more powerful performance than this engine, let alone atomic engines, Nuclear engine and ion engine.


    Therefore, if necessary, Wang Bin can buy more powerful engine technology from the system.


    "Yes! Mr. Wang, I also believe in your Tiangong technology. After all, other people may not know about your Tiangong technology''s R & D ability in aviation development, but I know it very well, so I believe you Tiangong technology can definitely develop more advanced engines in the future!" at this time, chief Engineer Lin came to Wang Bin after checking the aircraft, Hearing what Wang Bin said, he also said.


    Then, after chatting with general Qiu and others, Wang Bin came to the seventh master who had just passed the test flight and conducted a deeper inspection.


    However, the results of the inspection made Wang Bin and others very sorry. Because the seventh master experienced a hell of test flight for it, there were cracks not only in the wing oil tank of the aircraft, but also in many other parts of the aircraft. Even some of the internal structure of the aircraft had been deformed, so it was obvious, The seventh master has been unable to complete the next test flight. After all, this situation has made the seventh master very dangerous. If the test flight is carried out, it is likely to cause disintegration in the air.


    But fortunately, they not only prepared such a test plane for this test flight, but also a spare plane in addition to this one.


    Of course, the other one is the same as this one. It is also a seventh master fighter.


    Wang Bin, chief engineer Lin, Professor Zhang and others spent more than a week in the air force base. After all, there were a lot of subjects for off-site test flight, but not just the previous projects. Fortunately, in the test flight subjects in the next few days, the other seventh master performed very well and did not have any problems.


    Of course, this also has something to do with general Qiu''s strict restrictions on flying at a speed of more than 30000 meters and Mach 3 again.


    After all, flying at such a speed and altitude is not something that ordinary aircraft can bear. Even the third and fourth generation fighters may not be able to bear, let alone the seventh generation fighter. Even if the seventh generation fighter itself is a supersonic fighter, it is absolutely unbearable. The previous one is the best one.


    At the same time, in these days, Wang Bin, general Qiu and others have gradually become familiar. Of course, Zhao Feng, as a test pilot, is also expected to be very familiar.


    In the next few days, the flight test work was very perfect, and there was no situation again. Therefore, after all the work was completed, Wang Bin, Professor Cha and others finally returned to Tiangong technology, and the first time they returned to Tiangong technology, they told everyone in the laboratory about the off-site flight test, The laboratory staff were very happy.


    Of course, just after Wang Bin''s test flight and returned to Tiangong technology, general Qiu also reported the test flight of Tiangong technology in their base to the superior. At the same time, he was full of praise for the engine developed by Wang Bin and Tiangong technology. I hope the superior can approve the qualification certificate of Tiangong technology as soon as possible and replace the engine as soon as possible.


    .......


    Tiangong technology.


    After Wang Bin answered them about Tiangong technology, he immediately returned to the mechanical laboratory and continued to optimize the Tiangong 001 UAV they were developing with Yu Ping.


    Of course, at this time, the optimization of the UAV has been almost carried out. After all, Yu Pingping and others have been optimizing the UAV during the period when Wang Bin and others went for off-site test flight, and even Professor Dai and others have participated in it. Therefore, the UAV can carry out a second test flight, but this test flight, Wang Bin, they don''t have to go to the provincial test flight base of 969 group, but can directly carry out it in their Tiangong technology.


    Because after such a long time of construction, a section of the flight runway of Tiangong technology has been completed, that is, the one kilometer runway in the first part. You know, the runway built by Tiangong technology is not an ordinary runway, but an ultra long runway. After the construction is completed, This is a runway with a length of five kilometers, which is enough to take off and land any large aircraft in the world. Even if it is the largest aircraft in the world, it will A225 have no problem.


    In addition, the width of this runway has reached 65 meters. After all, their company has obtained the Phoenix bomber from Donald before research and development, and the volume of this Bomber can be compared with A225, even larger than A225, and its overall weight is larger. Therefore, the requirements for the runway will not be ordinary shells, You have to use shells that exceed the standard.


    However, due to the huge funds required for the construction of super runway and the long construction cycle, so far, Wang Bin and their Tiangong technology have only completed one fifth of the runway, that is, about one kilometer.


    However, although it will take a long time to complete the construction of a five kilometer runway, a one kilometer runway is enough for the Tiangong 001 UAV developed by their Tiangong science and Technology Institute. After all, even if the UAV is fully loaded and full of oil, its takeoff distance is only five or six hundred meters, which is completely enough.


    Of course, if Tiangong technology wants to carry out the test flight of UAV, only having a runway is certainly not enough. It must also have the right to use the temporary airspace. For the application for the right to use the airspace, Wang Bin has already submitted it and has been approved.


    In other words, in the future, if Wang Bin and their Tiangong technology want to carry out any aircraft test flight, they don''t have to go to other places for test flight, as long as they carry out it on their own side.
