Chapter 253 (1/2)

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.
