After a long time, the look of Professor poke recovered, and the trembling of his body finally stopped, which relieved Wang Bin.


    "Mr. Wang! Since this news is true, it is definitely good news for the large bypass turbofan engine we are developing. With this material, we can not only make our engine more powerful and lighter, but also save more fuel in terms of fuel consumption." Professor Zhang calmed his mood, Raised his head and said to Wang Bin.


    Wang Bin naturally looks forward to the large bypass ratio turbofan being developed. At the same time, he is also very clear about the positioning and some data of this engine.


    The engine they are developing by Tiangong technology is positioned as the engine of regional jet airliner, and different from the previous military turbojet engine, the turbojet engine developed before can be said to be only a first generation engine, but Wang Bin and they ran directly to the fourth generation engine for this turbofan engine.


    After all, compared with the turbojet engine, the turbofan engine is the field that Professor Chua is best at and is most familiar with. Even in the past, Professor Chua designed several turbofan engines himself. Although these engines were not manufactured because of various defects, they have the previous foundation, With the help of Professor Dai and Professor Zhang, it is not difficult for them to produce a high-performance fourth generation civil aviation large culvert than civil aviation engine.


    The maximum thrust of the turbofan engine with large bypass ratio designed by Professor Cha is not very large, about a little more than 22 tons, while the thrust in cruise state is only about 20 tons. Although the thrust is not much stronger than the turbofan engine developed by them before, in terms of fuel consumption and safety, However, it is not comparable to the previous turbojet engine at all. According to Professor CuO''s design data, the fuel consumption of this large culvert is about twice that of the previous turbojet engine.


    At the same time, in terms of reliability, this engine is more reliable, but due to bearing and other reasons, the whole life data of this engine can only be similar to that of the previous turbojet engine


    However, the weight of this engine is much heavier than that of the previous turbojet engine. The weight of a single engine reaches about three tons.


    When Wang Bin looked at the data of the turbofan engine with large bypass ratio developed by Professor Zhang and others, Professor Zhang said: "Mr. Wang! With this new super high temperature resistant alloy material, I am confident that the weight of the engine we are manufacturing can be reduced to less than two tons. At the same time, the maximum thrust can definitely be increased to more than 26 tons. The most important thing is that the fuel consumption will be lower, at least one tenth lower than the current data."


    In the following days, Wang Bin also ran back and forth in the laboratory and workshop. At the same time, some super alloys developed by Professor Zhang have been produced. Although this alloy is much more difficult to smelt than other materials, it also needs more scarce elements, including many strategic scarce elements.


    Even compared with copper based superconducting materials, the smelting difficulty of this metal is much higher. Therefore, this metal is destined to be unable to be mass produced as ordinary steel. It can only be produced on a small scale. Some transparent Tiangong technology can be used by itself. After all, if it is mass produced on a large scale, not to mention anything else, it can be used only by purchasing scarce raw materials on a large scale in the mall The little energy money Wang Bin earned in the mall ran out.


    Of course, the difficulty of smelting and the good properties of metal mean that the processing of this metal is also difficult. At the same time, it is also difficult in welding. It also has high requirements for props and large loss. It is even more difficult than the processing of special glass.


    But fortunately, in order to process this alloy material, Wang Bin specially purchased some special materials from Tony for processing those super hard materials.


    In the precision machining workshop, Wang Bin and master Zhou of the precision machining workshop stood frowning in front of an ultra-high precision CNC machine tool and looked at the machine tool processing internal blades, which was developed by Yu Pingping and others.


    With the continuous processing, the parts that had been processed very smoothly suddenly made a clear sound, and a corner of the machine tool prop collapsed directly. It is obvious that the processing can not continue at this time.


    "Master Zhou, there seems to be something wrong with the situation! Today this tool seems to be the tenth damaged tool! It seems that the hardness of this newly developed special steel has exceeded our expectations!" seeing this situation, Wang Bin said helplessly.


    "Mr. Wang, you are right. This is indeed our tenth tool today. However, compared with other machine tools, it is good that the speed of the tool is higher than that of other machine tools due to the machine tool developed by Tiangong technology.


    For other machine tools, take Master Zhang''s machine tool. Because the speed is much lower than that of our machine tool, they have damaged nearly 20 tools only this morning. It can be said that they will damage one tool in less than 20 minutes! "Master Zhou said helplessly.


    After listening to master Zhou''s words, Wang Bin frowned deeper.


    "Master Zhou, the damage of the cutting tool is so serious that it will not work. Let alone the cost of the cutting tool. After all, it is only a small problem for civilized Tiangong technology, but the delay in production is a big problem. After all, many parts will be made of this metal in the future, including aerospace laboratories and factories, so I We must find a way to solve this problem, "Wang Bin said.


    Master Zhou also nodded. In fact, master Zhou has long been aware of this problem and has happily responded to Wang Bin many times, but this problem has not been solved, or can''t think of any good solution.


    "Master Zhou, if you can''t, use the tools in the No. 1 tool warehouse first! Although the prices of the tools in the No. 1 tool warehouse are very high, and if they are converted into money, at least one of them should be more than ten million, there is no way. In order to process smoothly, we can only use which tool first. As for the problem of tools, I''ll go to the material laboratory and have a look Professor Zhang, do they have any way to see if they can find a way to develop the corresponding tool steel, "Wang Bin said.
