Wang Bin naturally didn''t know about Beixing. At this time, their 300 hour uninterrupted endurance test run of Tiangong technology has begun, and this time, like the previous 150 hours, it is a test run with maximum power.


    In addition, since the 300 hour endurance test run has begun, Wang Bin Yayao contacted the high-altitude test bench and wind tunnel for verification test. For these, because Wang Bin and Tiangong technology have no conditions, they must ask Tiangong technology to help the official.


    So after the 300 hour test run, Wang Bin immediately called chief engineer Lin of 969 group, hoping that he could find a way.


    "Mr. Wang! I heard that your company has started a 300 hour endurance test run. I don''t know if this is true." when Wang Bin called chief engineer Lin, chief engineer Lin took the lead in saying.


    "Yes, chief engineer Lin! The aircraft launch of our Tiangong technology has started 300 hours of endurance verification test. If it goes well, we will carry out 1500 hours of verification test, as well as high-altitude platform verification test and wind tunnel verification test. However, since our Tiangong technology does not have such conditions at present, I wonder if chief engineer Lin has this side Wang Bin also said directly after listening to chief engineer Lin''s words.


    "High altitude platform and wind tunnel test? Yes, we have both high altitude platform and wind tunnel in 969 group, and during this period, we also happen to have free fiefdoms and high altitude platform. Send the engine in two days! I will help you arrange this test. However, we still have to charge for the cost. After all, this is not my personal thing, but our country "Home!" Mr. Lin nodded and said,


    "Yes, thank chief engineer Lin!" Wang Bin said happily after listening to chief engineer Lin.


    "By the way, Mr. Wang, there is another good news for you. That is, the project you applied for has been settled. Although it is impossible to tell you the specific results, there should be no problem with the production license of the engine you developed." Mr. Lin said.


    "Really! There''s no problem with the production license, great!" when Wang Bin listened to chief engineer Lin''s words, he was excited at once. At the same time, his heart was as relaxed as putting down a heavy burden. After all, the most important thing for their Tiangong technology engine is the production license.


    Then Wang Bin and chief engineer Lin talked for a while. He hung up the phone. At the same time, the excitement in his heart did not subside for a long time.


    After all, for their Tiangong technology, it doesn''t matter whether they can actually establish a project or not, and whether they can get the national scientific research funds in this regard. After all, their Tiangong technology is not poor now. Let alone others, in the sale of special bearing steel, Tiangong special materials company under Tiangong technology has transferred a lot of money during this period of time, If all this money is used to develop engines, it is absolutely enough.


    Therefore, the production license is what he is most worried about. Now, after all, the engines of manned aircraft and unmanned aircraft are two different things! If the engine is successfully developed, but there is no production license, it will be embarrassing. After all, the engines they produce can not be sold without a production license.


    After hanging up, Wang Bin immediately walked out of his office and soon drove to the aerospace engine laboratory to tell the good news to the R & D personnel including Professor Zhang and Professor Dai.


    Professor Cha and others were also very excited after hearing the news from Wang Bin. After all, although the engine was not designed by them and the drawings were provided by Wang Bin, they also paid considerable attention to the engine and were in the process of R & D and test run during this period, They are under great pressure.


    Now, the production license of the engine has finally come to an end. How can this make them not excited.


    "Boss! It''s really great. Our engine finally has an identity. In this case, after 300 hours of verification and test run, we can also build this production line. However, there are some regrets, that is, our application for project approval has not been finalized yet. If the project approval can be passed, it will be perfect." Professor poke said to Wang Bin with a smile.


    "Yes, as long as the production license can come down, we can build the production line. As for the project approval, it doesn''t matter if we can''t pass. After all, Tiangong technology is not poor in scientific research funds." Wang Bin said.


    "Mr. Wang! This is not just a matter of scientific research funds. After all, once the project is successfully established, it will have great benefits in other aspects, such as the sales of these engines in the future, as well as the recognition of the military," Professor Zhang said.


    Before his retirement, Professor Zhang was affiliated to the official scientific research institute, so he was very clear about these things. He had to pass or not pass the project, which has a great impact on the future of the engine. Apart from others, just the production license, if it can pass the project, they don''t have to worry so much.


    "By the way, Professor Zhang, I have another good news to tell you that the high-altitude platform and wind tunnel test have been settled. Chief engineer Lin promised us to use the wind tunnel and high-altitude test platform of their 969 group for test verification." Wang Bin said to his husband.


    "Really? That''s great. The wind tunnel and high-altitude test bench are solved. As long as there is no problem with the verification data, we can carry out small batch production. At the same time, we can also install our engine on the UAV for testing." when Professor Zhang heard the good news from Wang bin again, Professor Zhang was also very excited.


    After a long time, Professor Zhang calmed down and looked again at the engine running at full power on the test bench. He was reluctant to leave for a long time.


    At the same time, not long after Wang Bin told Professor Zhang and others the news, all the R & D personnel in the aerospace engine laboratory knew the good news. As participants in the R & D and test run of this engine, they were naturally very excited, and even some people jumped and shouted on the spot.


    After all, they are not professors. Many of them have just come out of school, and the engine developed this time is actually the first time in their life that they have really participated in the R & D process of aeroengine.


    So they naturally don''t want the engine they participated in R & D for the first time in their life to die. Now, this engine finally has its own identity, which makes them unhappy.
