After opening the projection, Wang Bin first let them see for themselves and didn''t speak.


    While Qi Wenbo and Xiao Liu looked at the engine in the picture, they were more and more surprised, because the engine in the picture didn''t look like the first generation, the second generation or even the third generation.


    So they thought to themselves, is the engine designed and manufactured by Tiangong technology really a fourth generation engine?


    While Qi Wenbo and Xiao Liu were thinking about this, Wang Bin finally spoke.


    Wang Bin said: "as you can see, the engine developed by Tiangong technology is not the first generation, the second generation or even the third generation turbofan engine, but a fourth generation turbofan engine for regional airliners. In terms of performance, it is far superior to the same type of regional airliner engine of international engine giants......."


    With Wang Bin''s introduction, Qi Wenbo and Xiao Liu know more and more about this engine. Of course, their hearts are more and more surprised.


    After all, before they came to Tiangong technology, they all thought that although Tiangong technology may develop turbofan engine, in their heart, even if Tiangong technology developed turbofan engine, its technical level is very likely to be only around the first and second generations, and it is impossible to reach or exceed the third generation level.


    Even before, they had heard what Wang Xu said, but it was just what Wang Xu said orally. There was no real data, but now it is different. The engine on the projection picture in front of them is clearly marked with some basic data of this engine.


    In addition, President Wang of Tiangong technology also introduced Wang Bin. As insiders, at this time, they have some belief that Wang Bin and Tiangong technology have developed a turbofan engine, and this engine is definitely not the first and second generation engine.


    According to the data introduced by President Tiangong science and Technology Wang, this engine is at least a third-generation engine or even a fourth-generation engine.


    Even if they dare not imagine, they finally believe what Wang Xu said before. The engine developed by Tiangong technology is a fourth generation turbofan engine, not a first, second or even third generation engine.


    The projection pictures that Wang Bin showed them were very detailed, and even the anatomical drawings of the engine. It can be said that only from these projection drawings, we can see that this engine is definitely not simple.


    In fact, the reason why Wang Bin has these pictures in his hands now is not because Wang Bin knows that Qi Wenbo and others will come to Tiangong technology.


    Because Wang Bin didn''t know before, Qi Wenbo and others wanted to come to their Tiangong technology to see the turbofan engine.


    Wang Bin and their Tiangong technology have these pictures. In fact, this is prepared for the bamboo sea air show in the near future.


    At the same time, not only this product, that is, S001 and S002 turbofan engines, has these pictures and videos, but also other products of Tiangong technology, such as the previous tg001 engine, the tg001a engine being developed now, and the electric helicopter engine, all have detailed color pictures.


    At the same time, with Wang Bin''s introduction, Qi Wenbo and others were more and more frightened.


    More than ten thrust weight ratios, fan blades made of special glass!


    The combustion chamber and turbine blades made of special steel have a maximum high temperature resistance of nearly 3000 degrees!


    With ultra-low fuel consumption, ultra-high reliability and safety, the first overhaul time can reach more than 10000 hours, and the service life of the whole machine can even reach 40000 or 50000 hours.


    Therefore, after Wang Bin''s introduction, whether Qi Wenbo or Xiao Liu did not respond for a long time, and the data Wang Bin said was always floating in their minds, just like the computer crashed.


    Here! Here! How is this possible? Is this the engine of a regional jet? Not to mention anything else, just in terms of thrust, it is more than enough to put this engine on the trunk airliner.


    Today''s engineering technology is so powerful that it can develop such an excellent engine. More importantly, according to Wang Bin, it took them more than half a year to develop this engine from beginning to end! Did they hang up on Tiangong technology, or did they get alien technology?


    Then Qi Wenbo immediately threw such an idea out of his mind. After all, this is the real world rather than science fiction, so such an assumption is impossible to appear in the real society.


    Of course, not many of these things introduced by Wang Bin are just some basic data, and there are more data that need to be kept confidential. Wang Bin did not introduce such data. After all, no matter which aero-engine R & D company will not make it public.


    Seeing the surprised bodies of Qi Wenbo and Xiao Liu, Wang Bin smiled and said proudly, "manager Qi! Assistant Liu! How about this engine of Tiangong technology? Is it suitable for your Donghai aircraft?"


    However, as soon as Wang Bin finished speaking, Qi Wenbo blurted out: "President Wang! This is impossible! This is the regional airliner engine developed by your Tiangong Technology Institute, and its performance is too excellent! It has subverted my imagination."


    After listening to Qi Wenbo, Wang Bin was not angry, but smiled and said to him, "yes! This is the engine developed by Tiangong technology, the turbofan engine of regional airliner!"


    "Mr. Wang! I''m sorry, I''m not questioning your Tiangong technology, but the performance of your engine is too excellent. Even if it is placed on a larger trunk airliner, the performance of this engine is enough!" Qi Wenbo, who regained consciousness, hurriedly explained.


    Wang Bin nodded, then smiled and continued: "manager Qi, don''t worry, I don''t care. I can understand your mood, but the data I said are real data, and there is no exaggeration. After all, our data are really in front of you.


    At the same time, if manager Qi, if you want the engine of trunk airliner, Tiangong technology also has it, and its performance will be better. Its maximum thrust will be at least 40 tons. At the same time, the self weight of the engine will not be much heavier than this engine. "


    When Wang Bin finished, neither Qi Wenbo nor Xiao Liu spoke for a long time, but quietly thought about the data Wang Bin said. After a long time, he said, "President Wang, I don''t know if I can see the fan blades and turbine blades of your Tiangong technology engine?"


    "Yes!" Wang Bin didn''t refuse Qi Wenbo''s request. After all, whether it''s fan blades or turbine blades, except in terms of materials, others don''t need to be kept confidential.
