Super Weapon Swap System

Robert is continuing to explain the problems. Some Chinese people here don't understand cow language at all, but the scholar is translating at the same time. Those proper nouns can be translated perfectly. In this way, people here are seriously recording.

As soon as his Highness the prince leaves, even if the Niu countryman goes back on his word, at least his own side knows the overall process.

Qin Guan is also listening to the specific content. Qin Guan actually doesn't understand it, but he can also listen to it. Looking at the expression of his own people, it seems that this roadblock can be conquered.

In fact, an expert looking at the doorway is just a few words of advice, which can make your side smooth their ideas and make a breakthrough.

Robert, I said there was an hour before and after. It was long and boring enough.

Andrew couldn't sit still several times, but he could only continue to listen to Xiang Jing with interest.

Finally, Robert finished.

"I have a question." at this time, Qin Guan said, "this blade is a complex machining shape. Can we use CNC machine tools to process it?"

CNC machining? After hearing Qin Guan's words, Stanley finally spoke: "CNC machine tool processing requires multi axis CNC machine tools, so as to have high enough accuracy, carry out no allowance processing, and it takes about three months to process a blade. We only start to try to use CNC machine tools on the latest engine."

Stanley explained clearly, but also told the other party a reason, want to adopt this technology? Don't dream in the kingdom of Han.

Even if Han is the bridgehead against Xiong, the Western technology export to Han is also limited. Those backward things, such as Spey engine, can be exported, and the processing technology is also backward. Even so, even the slightly advanced blade processing technology should be stuck in the neck of Han.

As for CNC machining? Then stop dreaming.

The high-tech embargo imposed by the West on the Han country has always existed. How is it possible to export this most advanced technology to the Han country?

This sentence is enough. At least it proves that NC machine tool processing is possible. When you go back, you can study it yourself, and then pull several sets from the machine tool cemetery to your engine factory!

As for talents... Technical talents, it is always a difficult problem!

"With regard to Spey's technical problems, we believe that our two sides will certainly work together to complete the project." Qin Guan knew that this guy would not stay long when he looked at the prince's absent-minded appearance over there.

So, let's just have some fun and mobilize the enthusiasm of Niu people.

"Now, we are also optimistic about the future of Spey," Qin Guan continued. "I wonder if you are interested in continuing to improve and develop and increase the thrust on the basis of Spey?"

In later generations, the introduction of Spey in China was almost half an abandoned project. There was nothing else except equipment for Flying Leopard.

At the same time, at that time, there were three uncles and ten turbofans in China. Now, the weak foundation in China determines that it is necessary to develop the domestic power system with Spey.

How?

For example, after understanding Spey's technology, we can improve the thrust weight ratio, reduce fuel consumption, overcome the inherent defects of poor low altitude performance, and even gradually come up with a magic modified model based on the localization of Spey's material industry and processing industry, such as modifying the shape and size of compressors, blades, fans, and even using new materials, manufacturing processes and new materials.

This is not impossible, because after Spey was exported to Eagle, it was given the number of the new tf41 engine. The non afterburner version of this engine was used on the A-7. At the same time, Alison company developed an additional version to replace the unreliable tf30 engine on the male cat.

By improving the compressor and other components, the thrust of this increased version finally exceeds 10 tons, and even has the potential to further increase to 11.5 tons.

If it is the latter thrust, it will be enough for our new third-generation aircraft for the time being.

It takes time to understand the technology of Spey in China. It takes more time to improve on the basis of Spey. If we develop it together with the Niu people here, we can greatly speed up the progress.

Of course, there will be many problems in the middle. The capricious people of Niu have a clear understanding. They are likely to get the money and ask for more.

In addition to increasing the thrust, another aspect is the development of civil use. The culvert ratio of Spey mk202 is now 0.62. Compared with jt3d and jt8d of Yingguo in the same period, if the culvert ratio is enlarged to about 1-2, the total quality should be within an acceptable range. It is no problem that the normal thrust reaches 6-8 tons, so we can get a model with poor thrust weight ratio, However, jt3d and jt8d class I aircraft with lower fuel consumption.

If there is such a thing, that is to say, the aircraft can reach the level of jt3d Boeing B707, that is, Yun 10 is no problem.

In those years, one problem was political, the other was the engine. Although it was said that China began to imitate the turbofan 8 engine, it could only be hehe.

A large number of parts are made of jt3d, which can also be called imitation? Just look at the current domestic level. A Spey's engine blade processing can perplex for several years. Qin Guan has reservations that turbofans can be imitated in China in a few years.

Compared with this unreliable turbofan 8, it's better to use the improvement of Spey to become a series. After all, Spey already has a civil model.

Then, on this basis, through the improvement of annular combustion chamber, similar to xiongguo d-30kp series, the culvert ratio can be increased to about 2.5 and the core flow can be increased to about 110kg / s, which can reach the 120 kn level of d-30kp2.

In this case, the historical boom 8 scheme and Yun 9 scheme have been settled. The heart of domestic large aircraft does not need to be controlled by others. Although its performance may be poor, it can at least be used. At the same time, with the help of NiuGuo, it can even increase the culvert ratio to 3.5

Under the condition that the core engine remains unchanged, various modifications can be carried out. The premise is that the technology of this engine must be fully understood!

Even marine gas turbines can be built on this basis. After all, there are some gas turbines refitted by Spey. For example, the ship gas turbine with model s * M-1 was modified by Niu Guoren.

It can be said that Spey's complete understanding is of far-reaching significance to the Han country, and the heart problem can be solved for the time being.

However, it is very difficult to understand this. If we take the Niu people to improve Spey together, the progress can be greatly accelerated.

(after writing here, Huaxiong suddenly laments that if Spey really understood his skills, our heart problem would have been solved long ago. Well, in Huaxiong's novels, we must make up for this regret.)
