Chapter 1867: Design Resources

Qin's point of view, he already knew roughly.
The J-6 fighter jet only satisfies the ability to 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 of the imperfect flight control system. When the pilot uses hydraulic control, the flight cannot be guaranteed. After all, people have reaction time. Only after the 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, there are also some small nozzles that are constantly adjusted. If it is all controlled by the pilot manually, not to mention the reaction time, the operation is cumbersome, and it will cause people to collapse.
The J-6 vertical take-off and landing fighter jets finally stayed on paper and did not continue. In the subsequent domestic environment, there were no opportunities for scientific research.
"Yes, this layout is not perfect. It's best to make it like the Yak-38, open behind the pilot and install a lift fan." Qin Guan said, "The project I'm going to talk about this time has something to do with this. Great relationship."
Qin Guan finally came to the topic, and everyone listened to Qin Guan's narration expectantly.
"Xiong is developing a follow-up model of Yak-38, called Yak-141 vertical take-off and landing fighter." Qin Guan said: "They originally planned to use the same lift engine for this fighter. Under my suggestion, they We want to try the lift fan, so maybe we can conduct extensive and in-depth cooperation with the Yakleev Design Bureau of Xiong Country in this field."
Yak-141? Mr. Gu has a lot of doubts in his heart. Although his own technology has some reserves, there is absolutely no way to compare it with Xiong Guoren's. After all, they have matured. Now, if you cooperate, what can you do? Come? It's totally a foil.
Gu always has no confidence.
"Their performance of this fighter is more powerful. Although there is only one engine at the rear, it has a thrust of 150 tons. My advice to them is to draw the 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 is only a waste of space for a lift fan. It is already the most optimized solution. At the same time, when placed in this position, there is no need to worry about the resistance of the lift fan. After taking off, the air inlet and outlet will be closed."
"Ms. Qin, your proposal is quite good, but, but." Mr. Gu said a few in a row.
However, we don't have this kind of technology!
You go out to fudge the bear people, that is normal, our lift fan, you just know, now let us go to fudge the bear people, it can’t be done, 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 you continue to say that you can't do it now, what if Qin Guan hands this project to someone else?
What do they live on?
This is their last hope! In the past few years, many capable designers in the institute have left and were poached by other design institutes. If they continue like this, the final outcome of the institute will definitely be the collapse of the whole institute. Mr. Gu does not hope See things like this happen.
Gu always knew it well.
I can't say it now, so, after a few of them came down, my face blushed.
"You are worried about the technology, don't worry about this." Qin Guan said: "I have brought some materials, our research institute, we have to work hard recently. I have thoroughly learned all these technical materials, and we will meet with Xiong Guoren in the future. With the cooperation, we can become technical authority."
what? Mr. Qin has brought technology? President Gu immediately showed joy on his face, as if he brought that fighter plane back then. Everyone was shocked. However, the fighter plane alone cannot be copied. Now, with the technology, then All right.
"Xiucai, first show you the profile." Qin Guan said.
Qin Guan came by plane. When he got off and visited back and forth, there was also a car that began to pick up goods from the plane. There were three cars of paper materials!
In addition to the paper data, there are also data stored on the computer. After hearing Qin Guan’s words, the Xiucai immediately turned on the laptop he carried with him and connected it to the projector on the table, and then turned off the lights. Everyone You can see the picture on the front projector screen.
Suddenly, everyone was bright.
This is a color picture. The notes on the side are all in English. Because of the rush, the scholar did not have time to turn the characters on it into Chinese characters. But this is also good. This illustrates a problem. These technical materials of Qin Guan, It was obtained from Eagle Country through some secret means, so it would be easy to explain the past.
Of course, this is for everyone to guess.
This is a lift fan design. The drive shaft from the main engine behind is pink. After entering the lift fan engine, it turns green. You can see the bevel gears of the drive and the yellow main fan inside. Seeing the beauty of its simplicity and complexity, everyone is sighing.
President Qin is great, he is ready for us!
When Qin Guan came, he had already started the weapon data exchange and packed all the data of the F-35's power unit.
However, it absolutely cannot be copied. After all, the F135 engine has an afterburner thrust of 19 tons and a thrust-to-weight ratio of more than 10, which is definitely an engine against the sky.
The thrust of the Yak 141 engine is only 15 tons, and the thrust-to-weight ratio is less than 6. The power of the two engines is different, and the lift fans that can be driven are different.
Regardless of the fact that the lift fan looks simple, there is also a complicated knowledge of fluid mechanics inside. It is necessary to absorb the design principles of this engine and then modify it to be able to launch a similar lift fan system.
"Mr Qin, this design is quite ingenious. Look at this, the fan clutch has done a great job. However, we have put forward higher requirements on our materials. Looking at this side, the meaning of this lift fan is very good. Be careful, here is a restrained contraction, which can further increase the thrust."
Just looking at the drawings, Mr. Gu started to analyze. He once participated in the J-6 vertical take-off and landing fighter project, and now Mr. Gu is very clear in his analysis.
