Chapter 872

After hanging up with Li Yunfeng, Jiang Yanhai thought about it, called Professor Zhao again, and then told Professor Zhao about the general situation.

Professor Zhao was also very excited when he heard what Jiang Yanhai said that the engine had been recognized by the above and that it was necessary to speed up the progress in an all-round way, which was certainly a good thing for them.

It is different from Eagle sauce in China. These of Eagle sauce are private enterprises, and they have formed a systematic thing. They don't want anything in this regard.

Moreover, even if Pratt Whitney engine company has developed a more powerful engine, sometimes it may not be taken out directly, because the U.S. military has no purchase demand. What do they do when they develop it?

In fact, although they have technical reserves for the engine, they rarely carry out research and development in advance. They start research and development only after they get the R & D expenses of the military.

These things are not like pharmaceutical companies or chip companies. Commercial companies will carry out pre research and development in advance.

However, it is different in China. China is very eager for this thing. Once it has the technology that can make the great leap forward development of domestic military forces, of course, it will be developed immediately.

As fast as you can!

After notifying Professor Zhao and them, Professor Zhao will contact people in Taihang, and then send an engine to the high-altitude test bench there for test run under special conditions.

After doing this, Jiang Yanhai began to concentrate on drawing drawings with Er Dan.

His design was completed in his mind before, with the assistance of two eggs. In fact, the overall design drawing of the phantom has been almost the same. Of course, there are no problems at all and it is unlikely, but these problems are all about details, since Liu Lao and they join in.

Then these will be solved very quickly.

In other words, it is not far from the day when the phantom is completely produced. Jiang Yanhai submitted the design drawings of phantom directly according to the final version, that is, more than 70% of the fuselage uses composite materials.

The next afternoon, Jiang Yanhai finished sorting out all the drawings. In fact, drawing is difficult for ordinary personal computers. This is not a simple job. How many design drawings are there for a fighter?!

It can be said to be an astronomical figure, not to mention the design drawings and data of some materials.

However, the above never asked what kind of computer Jiang Yanhai completed such a design on. They all know Jiang Yanhai's hacker strength, so they didn't ask, but they all know that this must not be completed on the small laptop in his hand.

It also gives Jiang Yanhai enough trust.

In fact, there are many of these drawings. Of course, there is another advantage of electronic drawings, which is much less than paper drawings.

Because many drawings can be displayed in 3D, but if they are paper, it is impossible to do so. They will be divided into countless drawings.

If the paper map is estimated, it is estimated that it will weigh at least two or three tons when printed.

As for so many pictures, how did Jiang Yanhai complete it alone? No one asked, so he didn't say. Anyway, he can say that he started many years ago, which makes sense. No one knows when he really started.

After sorting out the drawings, Jiang Yanhai directly transmitted them to the secret server through the network. The transmission speed of the national defense network optical fiber goes without saying. Although there will be many paper drawings, there are not many electronic versions in fact.

After passing the document, Jiang Yanhai directly told Liu Lao.

What he didn't know was that after receiving the completed drawings, old Liu immediately began to classify these drawings. Under old Liu, there are many doctoral students who can use them.

These drawings are passed to different research departments by categories, especially the part about composite materials. Special personnel will be responsible for seeing how these things can be manufactured.

It can be said that in less than an hour, hundreds of people across the country took action because of these drawings. After finishing the later drawings, it is unknown how many people will be busy because of this.

After transmitting all the drawings, Jiang Yanhai reluctantly found that he seemed to have nothing to do for the time being.

The phantom has been completely explained. The next step is to see the material manufacturing of the phantom. Apart from the composite materials, other aspects are simpler. It's about the engine design. In addition, it's about the design of the magazine and the built-in missile hanger.

The phantom in the mirage simulation combat system can hang on so many terrible missiles because the solid rocket motor inside is extremely abnormal. For missiles with the same range, the missiles in the mirage simulation combat system are much smaller than those in reality.

That's why the phantom can mount so many missiles, but it's doomed to be impossible in reality.

However, it is inevitable that there are more missiles than J20.

Thinking of this, he thought of Ivan, or pishkov. After being rescued by himself, he has determined that as a solid rocket expert, Ivan's current achievements can reduce the volume of domestic air-to-air missiles by at least one third!

This will be good news for both phantom and J20. The number of missiles that can be mounted will inevitably increase.

On this holiday, why don't you meet Ivan yourself? Speaking of, I promised to see others last time. And Ivan can now be said to be Chinese. People want Chinese nationality.

It's nothing for Jiang Yanhai to see him, but it's certainly impossible to tell him his real situation.

Of course, before dealing with this matter, this birthday gift still needs to be given. I've known Li ruobai for more than two years.

Time passed quickly, as if it could be replaced by a pen.

But on the last birthday, I couldn't have given her a birthday at that time, and this time, I can't miss it.

Li ruobai has paid too much for himself. They all say that behind every successful man, there is a woman who supports him.

Jiang Yanhai doesn't know whether he is successful or not, but Li ruobai is the biggest pillar behind him. Anyway, it's natural for him to go to see his future wife during the holiday.

He called the hound and confirmed that Li ruobai had been in Jiangcheng, Hubei Province recently. At the Electronic Research Institute, Jiang Yanhai also went straight to Jiangcheng with what fan Tianlei gave himself.

When he arrived in Jiangcheng, Jiang Yanhai directly asked Erdan to search a jewelry company selling jade and buy a piece of jade. It's not carved. He can't really give the things brought by fan Tianlei to Li ruobai.
