However, the mood of Professor Zhang and Professor Dai can still be controlled, but the mood of others in the laboratory is different. After all, they have just come out of bear school! And this engine is also the first engine they participated in R & D and manufacturing! Now the certificate and airworthiness certificate of this engine have been solved, which means that their engine is a qualified product at this time. How can this make them not excited!


    Therefore, after hearing that the qualification certificate and airworthiness certificate of their fast engine were issued, there was a cheering from all workshops in the whole laboratory.


    Wang Bin, Professor Cha and others all set their eyes on the test workshop not far away and the engines that are still being tested, with a burst of pride in their hearts.


    You know, at this time, their engine has been tested for this period of time. At this time, the test time of the engine has exceeded 2200 hours, and there are no problems with the ten engines tested.


    In other words, the reliability of this engine in its life cycle is very reliable. After all, this is not a test run of an engine! But the test run of ten engines, and the test run time of each engine has exceeded 2000 hours. Such performance has definitely reached the level of world-class engines.


    Most importantly, although the engine has been tested for more than 2000 hours, this is not the full life of the engine. According to the inspection of the engine by Professor Zhang et al. At 2000 hours.


    Although the engine has been tested for 2000 hours, the internal situation is still very good. According to the calculation of Professor Zhang and others, the first overhaul time of the engine is at least more than 5000 hours, that is, the whole life of the engine is at least more than 15000 hours, It may even exceed the life of many aircraft bodies.


    ......


    On the day after general Qiu returned, Wang Bin''s Tiangong technology received the invitation of the military''s spring ordering meeting, which also surprised Wang Bin.


    After all, according to the news, it is very close to the date of this year''s military spring ordering meeting. It is only less than a week.


    Originally, Wang Bin thought that Tiangong technology had missed the military spring order meeting. Even if it was general Qiu''s invitation before, it was most likely the autumn order meeting. Now they actually received the request for the spring order meeting.


    So Wang Bin, Professor Zhang and others immediately took action and put all kinds of data together for the spring order meeting.


    "Mr. Wang! Unexpectedly, the military invited us to participate in this spring ordering meeting. According to my previous expectation, it would be great if we could participate in the autumn ordering meeting. It was actually spring. I think the military decided to attach great importance to our engine. Otherwise, they would never do so.


    At the same time, we can also see how urgent the military needs high-performance air launch. "When Wang Bin told Professor Cha the news, Professor Cha nodded happily.


    "Yes! I didn''t think so. When general Qiu asked us to go to the order meeting, I thought he was talking about the next order meeting, that is, the autumn order meeting," said Wang Bin.


    "Yes! Since the military needs high-performance engines so urgently, I wonder if our engine can be installed on our country''s No. 10 fighter?" Professor Dai said excitedly.


    "I think it is absolutely possible that our engine will be installed on fighter 10 or even other more advanced fighters in the future.


    After all, the thrust of this engine is there. Although it may not be able to reach the double three standard as it is installed on the seventh leaf and our own UAV, I think it is not difficult to make the flight limit speed of the tenth fighter reach the double two standard, or even reach a higher speed and altitude.


    At the same time, like the 11th or 15th fighter, evolution may also install a version of our engine. After all, with the thrust of our engine, the military will never ignore it.


    Although it is the first generation product, this engine still has many deficiencies, such as vector function, this engine still does not have, but the thrust of this engine is enough to make up for these deficiencies. "Professor Zhang nodded.


    ......


    Just when Wang Bin and Tiangong technology nervously sorted out various documents and data for the military meeting, he received a call from chief engineer Lin of 969 group.


    "Mr. Wang, Congratulations! I didn''t expect that Tiangong technology will also participate in this military meeting." chief engineer Lin said on the phone.


    Chief engineer Lin is not surprised that they know that Wang Bin and Tiangong technology have won the participation in the military subscription meeting. After all, with the energy of 969 group, it is not difficult to know. Moreover, 969 group will also participate in the military subscription meeting, and they are also one of the largest suppliers of military land combat equipment.


    "Thank you, chief engineer Lin. we Tiangong technology can make today''s achievements. Your credit is absolutely indispensable, chief engineer Lin. otherwise, chief engineer Lin, let''s go to Beixing this time. Then we''ll have a meal together to show our gratitude?" said Wang Bin.


    "OK! Let''s go together this time!" chief engineer Lin said heartily.


    "That''s settled."


    Wang Bin and their Tiangong technology have preliminarily drawn up a team to participate in the military order meeting.


    First of all, it is natural for Professor Zhang and others. As experts in aviation development and aircraft design, they must be indispensable. In addition, Jiang Zongliang, who is in charge of special glass in Tiangong technology, is also sure to bring it. After all, now in the field of special glass, the military and official military industrial groups are the largest customers!


    At the same time, Wang Bin is also ready to bring Yu Pingping and Jia Jie. After all, the UAV they participated in the production is also one of the products favored by the military!


    Of course, like Wang Bin and others, the major domestic aviation enterprises at this time are very interested in the military appointment meeting. After all, the military appointment meeting is very lively every spring or autumn.


    Not to mention anything else, just in terms of aviation equipment, the orders received by major aviation enterprises every year are not small, ranging from hundreds of millions or billions to tens of billions or even tens of billions. How can these enterprises give up such huge orders! Therefore, the team they discharged is naturally the core team of these enterprises.


    Although, compared with those large enterprises, what Wang Bin and Tiangong technology can come up with is still a little shabby. After all, they have only two or three products of Tiangong technology, that is, tg001 turbojet engine, Tiangong 001 UAV, special high-temperature resistant glass and special bearings.


    But in terms of technical content, these things of Tiangong technology are absolutely top-notch.


    Therefore, Wang Bin is confident that he will definitely get several big lists in this military appointment meeting.
