After all, just in terms of biological gene technology, the civilization gap between the two sides is indeed very large, and the gap between natural experimental equipment is absolutely huge. Maybe the top foreign experimental equipment in Wang Bin''s world is not as good as their ordinary equipment in Tony''s world.


    Soon, the two sides signed the contract under the systematic witness, and Wang Bin was also very careful in the process of signing the contract. After all, this is the first time that Wang Bin bought equipment from other countries after becoming the store owner of the science and technology mall.


    After signing the contract, Tony returned to his own world, and Wang Bin looked at the time and found that he had been in the technology Mall for nearly five hours, so he also quit the technology mall and returned to the real world.


    In the next few days, Wang Bin did not research and develop the remote control system and autonomous combat system of UAV in his own laboratory. Instead, after their Tiangong technology came every morning, he came to the aerospace laboratory to carry out the test run of which aircraft development with Professor Zhang and others. At the same time, he went to the hospital to accompany Professor Zhang every afternoon.


    Until three days later, Professor Zhang finally got the doctor''s permission and was discharged from the hospital. However, due to his old age, the doctor specially ordered that the working hours per day should not exceed four hours.


    Therefore, after he came back, Wang Bin did not let him continue the test run of the aircraft with Professor Cha and others, but asked him to continue to improve the large aircraft he obtained from Donald.


    At the same time, he specially invited several medical staff from the first high tech hospital to take care of the living and physical conditions of these old professors, including Professor Zhang.


    Of course, these days, in addition to staying in the laboratory every day, Wang Bin also sends people everywhere to look for talents in biology and genetic engineering, and he is still the kind of person who can be alone.


    At the same time, they are also very concerned about the project application and production license submitted by Tiangong technology. After all, this is the premise that Tiangong technology is developing this engine in the future.


    According to the information Wang Bin received from chief engineer Lin, although he did not directly explain the specific situation to Wang Bin, he told Wang Bin that now the superior has a certain conclusion about the project applied by Tiangong technology.


    Although they didn''t pass their application, they didn''t directly refuse the application. In a specific period of time, a professional aeroengine expert team will come to Tiangong technology for field investigation and audit. As long as Tiangong technology can pass the audit, everything will be no problem, otherwise, The engine of Tiangong technology can only be used as the engine of UAV.


    Six days passed quickly. During this period, Wang Bin and Tiangong''s engine have been carrying out 150 hour endurance test run, which is different from the 150 hour test run of general official aircraft launch and other enterprise aircraft launch. Due to Wang Bin''s willfulness, their 150 hour endurance test run of Tiangong is not a endurance test run in cruise state, At the same time, it is not simply a 150 hour endurance verification test run superimposed, but a 150 hour uninterrupted maximum thrust endurance verification test run.


    Such a verification test run for the engine has even exceeded the previous verification test run of swallowing ice and sand. After all, the 150 hour verification test run of other companies and R & D institutions is basically superimposed verification test run, which will never be fooled like Wang Bin''s Tiangong technology.


    Of course, Professor Zhang and others maintained a negative attitude towards this, and even had differences with Wang Bin for many times. However, they were finally persuaded by Wang Bin. After all, Wang Bin is the boss of Tiangong technology.


    As a private enterprise, as long as Wang Bin insists, others have no good way.


    In fact, this is also the reason why Wang Bin''s heart is holding his breath. Only their Tiangong technology engine can pass the 150 hour and 300 hour uninterrupted maximum thrust endurance test run, he doesn''t believe that with such performance, this engine can''t get a license. Even if it doesn''t work for 300 hours, what about 1000 hours?


    In the test shop, on the No. 123 test bench, the three aeroengines are running at full speed, and the controllers and their R & D personnel in the three control rooms are all focused on the engine data of the huge civilian in the control room.


    Of course, such a verification test run is actually a huge test for the test run personnel. After all, the engine has to work for more than six consecutive days. Even if strict shift measures have been taken, everyone can only record data in the control room for four hours, which is absolutely very tired.


    At this time, Wang Bin is also in the No. 1 control room, concentrating on the data on the screen, and his face is relatively relaxed. After all, the 150 hour maximum power verification test run of this engine has reached the final stage. As long as he survives today, this verification test run can be completed.


    However, at this time, no matter Wang Bin, Professor Zhang or other employees in the control room, they are in a very good mood. After nearly six days of verification test, none of the three engines for verification test run has a problem, and all operate normally. If there is no accident, this test run should not be a problem.


    After various verification tests during this period of time, these employees at the aerospace engine laboratory of Tiangong technology, including Professor Zhang, have great confidence in Wang Bin''s engine, because there were some problems on the test bench when these mining engines came out for the first test, All other test runs can pass at one time!


    In particular, they are most impressed by the ice swallowing, sand swallowing and anti-collision verification test. You know, if the engine developed by other companies is used for the ice swallowing, sand swallowing and anti-collision verification test like Tiangong technology, there will be more or less problems. What about their engine?


    On the second day after the test run, they disassembled and tested the tested engines. They were stunned by the test results. After such a harsh environment, there were no problems in the interior of their engine, but it was crystal clear without any scars and wear.


    You know, not to mention anything else, just swallow ice and sand to verify that the diameter of the largest ice used in the test run is more than one centimeter! If such a large ice block is another aeroengine, it will definitely end at the first time.


    But what about their engine? After such a hellish verification test run, the interior was actually intact, and even encountered the impact of birds the size of a hen (sucking the chicken directly into the air inlet). The engine was resolutely intact and continued to work normally, so they were naturally full of information about this verification test run.
