Chapter 1867

Qin Guan nodded. He was almost clear.

The J-6 fighter can only take off vertically, and there is no place to store the lift fan. However, in the end, this kind of aircraft has not been studied, mainly because the flight control system is imperfect. When the pilot uses hydraulic control, it can not ensure flight safety. After all, people have reaction time, and only after telex control is adopted, All these are automatically monitored by the computer, which is safe.

In order to control the flight attitude during take-off and landing, some small nozzles need to be continuously adjusted. If it is all controlled manually by the pilot, needless to say the reaction time, the operation is cumbersome and will collapse.

The J-6 VTOL fighter finally stayed on paper and did not continue. In the subsequent domestic environment, there was no opportunity for scientific research.

"Yes, this layout is not perfect. It's best to make it like jacques-38, open the mouth behind the pilot and install the lift fan." Qin Guan said: "the project I want to talk about this has a lot to do with this."

Qin Guan finally got to the point. Everyone was looking forward to listening to Qin Guan's narration.

"Xiong Guo is developing a follow-up model of jacques-38, called Jacques-141 vertical takeoff and landing fighter," Qin Guan said "This fighter originally intended to use the same lift engine. Under my suggestion, they wanted to try the lift fan. Therefore, we may have extensive and in-depth cooperation with yaklev Design Bureau of Xiong Guo in this field."

Jacques-141? President Gu has a lot of doubts. Although his own technology has some reserves, there is absolutely no way to compare it with that of Xiong Guoren. After all, others are mature. Now, what can you come up with if you cooperate? It's just to accompany him.

Gu always has no confidence.

"Their fighter has stronger performance. Although there is only one engine at the tail, it has 150 tons of thrust. My suggestion to them is to lead out the rotating shaft in the middle and plug it into the lift fan in front." Qin Guan said: "In this way, the problem of high fuel consumption is solved. It only wastes the space of a lift fan. It is already an optimized scheme. At the same time, if you put it in this position, you don't have to worry about the resistance caused by the lift fan. After takeoff, the air inlet and outlet will be closed."

"Mr. Qin, your proposal is quite good, but, but." Mr. Gu said several times.

But we don't have this technology!

It's normal for you to go out and fool the people of Xiong. You just know our lift fan. Now let's fool the people of Xiong. We can't do it. There are too many technical difficulties to overcome!

A 150 ton thrust engine. Do you know how much power that shaft needs to output?

However, Mr. Gu can't say that the current 6601 Institute really doesn't have any decent projects. If we continue to say that our own side can't do it now, what if Qin Guan gives this project to others?

What do they live on?

This is their last hope! In recent years, many capable designers in the Institute have gone and been poached by other design institutes. If they go on like this, the final outcome must be that the whole institute will collapse. Gu doesn't want to see such a thing happen.

Gu always knows.

I can't say now, so I can't wait for a few, and my face turns red.

"You're worried about technology. Don't worry about it." Qin Guan said, "I've brought some materials. Our institute needs to work hard recently to understand all these technical materials. In the future, with the cooperation with Xiong Guoren, we can be the technical authority."

What? President Qin has brought technology? President Gu immediately showed joy on his face, just like the fighter he brought at the beginning. Everyone was shocked. However, only the fighter can't be imitated. Now, with technology, it's good.

"Scholar, let me show you a brief introduction first," Qin Guan said.

Qin Guan came by plane. When he came down and visited back and forth, there was also a car that began to receive goods from the plane. There were three full cars of paper materials!

In addition to the paper materials, there are also the materials stored on the computer. After hearing Qin Guan's words, the scholar immediately opened the portable laptop and connected it with the projector on the table. Then, turn off the light, and you can see the picture on the projector screen in front of you.

Suddenly, everyone was in front of us.

This is a color picture. The notes beside it are all in English. Because they are in a hurry, the scholar didn't have time to turn the words on it into Chinese characters, but it's good. This shows a problem. These technical materials of Qin Guan were obtained from the eagle country through some secret ways, so it's easy to explain the past.

Of course, this is for everyone to guess.

This is the design scheme of the lift fan. The transmission shaft from the rear main engine is pink. After entering the lift fan engine, it turns green. You can see the transmission bevel gear, the Yellow main fan inside, and the simple and transparent beauty of its complexity. Everyone is constantly sighing.

President Qin is great. He's ready for us!

When Qin Guan came, he had started the weapon data exchange and packed all the data of the F-35 power unit.

However, it must not be copied. After all, the afterburner thrust of F135 engine is 19 tons, and the thrust weight ratio exceeds 10. It is definitely an anti sky engine.

The thrust of Jacques 141 engine is only 15 tons, and the thrust weight ratio is less than 6. The power of these two engines is different, and the lift fan they can drive is different.

Although the lift fan looks simple, it also has complex knowledge of hydrodynamics. We must absorb the design principle of this engine and then transform it before we can launch a similar lift fan system.

"Mr. Qin, the design is quite ingenious. You see, the fan clutch here is very good. However, it puts forward higher requirements for our materials. Look here, the connotation of the lift fan is very particular. There is an introverted contraction here, which can further increase the thrust."

Just looking at the drawings, Mr. Gu began to analyze. He once participated in the J-6 vertical takeoff and landing fighter project. Now Mr. Gu's analysis is clear and correct.
