At the same time, Wang Bin also knows that Qi Wenbo wants to see the fan blades and turbine blades of their engine. He also wants to judge whether the engine is a real fourth generation engine through the turbine blades and fan blades. After all, as a deputy general manager of an aircraft manufacturing company, he can still pass his own knowledge level, The level of the engine can be seen from the turbine fan and fan blades.


    Soon Wang Xu brought the two kinds of leaves and handed them to them.


    Qi Wenbo and Xiao Liu looked carefully after taking over the two kinds of blades. After taking over, Qi Wenbo and Xiao Liu found that the two kinds of blades are very different, not only in size and shape, but also in material.


    First of all, naturally, the fan blades are much larger than the turbine blades, but they are as wide as a palm. At the same time, in terms of material, because they are made of glass, the transparency is very high. In addition, the shape of the blades is not flat.


    Therefore, all kinds of refraction and reflection will occur in optical irradiation, which is very beautiful. Even more dazzling than some gemstones.


    In addition, because the special glass used in the fan blade is also very light in weight, it is naturally much lighter than the fan blade of general turbofan engine, at least about half lighter.


    Compared with fan blades, the situation of turbine blades is much more normal. After all, turbine blades are made of special steel, so they are not as dazzling as fan blades.


    However, it also presents its own aesthetic feeling. Although the special steel used to manufacture this turbine blade is reddish, the color is matte black because a layer of black high-temperature resistant material is coated on the surface after the turbine blade is manufactured.


    At the same time, in terms of weight, Qi Wenbo is about to clearly feel that it is much heavier than ordinary turbine blade materials, so he knows that the material of this blade is definitely different.


    Qi Wenbo and Xiao Liu are worthy of being from a large official aircraft manufacturer. After watching these blades, they already have some answers in their hearts.


    So he said, "Mr. Wang, to tell you the truth, these blades of Tiangong technology are not only excellent in material, but also impeccable in blade processing and shape.


    Even the blades produced by foreign engine giants are not necessarily better than you in shape design and processing, or even worse. "


    Wang Bin nodded and said: "Indeed, in these two aspects, Tiangong technology is really confident. First of all, it is naturally in the aspect of shape design. I won''t say much in China. Whether it is the official R & D unit or other units, I believe they can also design a better appearance. In the past, it was only limited to factors such as materials and processing that they couldn''t produce advanced engine Machine.


    In terms of processing technology, the equipment we use is no worse than the equipment used by foreign engine giants, and some are even more advanced and more precise. Even in the manufacturing process, we use a 100000 ton water press for forging. Therefore, our blades are definitely not comparable to foreign blades of the same type. "


    Then Wang Bin briefly introduced some processing technologies of these blades that do not need to be kept secret.


    After listening to Wang Bin''s introduction, they also realized the extraordinary features of these blades. At the same time, they also believed that the two turbofan engines of Tiangong technology were the fourth generation engines.


    So Qi Wenbo was a little excited at this time, and immediately opened his mouth to Wang Bin and said, "from these aspects, we can really see the extraordinary features of your engine. Whether in terms of comprehensive performance or thrust, even compared with foreign advanced engines, it is only strong."


    "It is indeed a very excellent engine. No matter I have some doubts, is it a waste to install this engine on our No. 19 regional airliner? After all, with the thrust of this engine, even if it is used on the trunk airliner, it is enough." Xiao Liu, who is not so excited as Qi Wenbo, said rationally.


    "Don''t worry! Manager Qi! Assistant Liu! Although our engine has reached nearly 20 tons in terms of maximum thrust, in terms of cruise thrust, it is only a little larger than the engines of ordinary regional airliners, not too much. At the same time, in terms of fuel consumption, it is less than ordinary!" After listening to Xiao Liu''s words, Wang Bin naturally knows what Xiao Liu is worried about.


    After all, the thrust of the engine is directly linked to the fuel consumption, and the thrust of this engine is so large that the fuel consumption will not be much lower.


    After listening to what Wang Bin said, Xiao Liu''s expression is obviously much better.


    At this time, Wang Bin said, "of course, if manager Qi and assistant Liu think this engine is still inappropriate, Tiangong technology can even develop an engine for your No. 19 regional airliner, which is not impossible."


    "Mr. Wang! That''s not necessary. After all, developing an engine is not a joke. Not to mention the investment in other aspects, just the investment in time can''t be completed in a moment and a half, at least in a few years or even longer!" Qi Wenbo shook his head and said.


    "Manager Qi! You are talking about the official R & D units under normal circumstances. After all, it will take a long time for them to start the project only in terms of project application and other procedures.


    Our Tiangong technology is not an official enterprise, and there is no need for cumbersome procedures.


    In addition, we Tiangong technology already have the core machine of the engine, so we can also save the time of developing the core machine.


    Most importantly, manager Qi, since you come to Tiangong technology, I think you should know the time when Tiangong technology develops this engine. Therefore, as long as your company needs, I can definitely develop the engine you need in three months.


    When Qi Wenbo listened to Wang Bin''s words, he suddenly realized that Tiangong technology is not a normal fast engine R & D enterprise. After all, a normal aviation development enterprise can''t come up with so many aeroengines in just six months.


    So he did not doubt that Wang Bin said he could develop an aeroengine within three months.


    So he immediately said excitedly, "well, although President Wang said that your engine is enough for our company''s current No. 19 regional airliner.


    However, in addition to this regional airliner, our company also needs several airliners. I hope President Wang and Tiangong technology can develop special engines for it. At the same time, we also hope that President Wang and Tiangong technology can tailor engines for trunk airliners! "
