Chapter 446: Women's material experts

Back then, the Air Force decided to introduce various electronic equipment from Marconi to transform the J-7 and follow the pace of the world. However, after all the deposits were paid, the Air Force no longer needed it.
At this time, these funds seemed to be wasted, so the 6611 Research Institute at that time decided to go on it by itself and exclusively for export. The M of the J-7M means export. After exporting, the Air Force changed its mind. I think this fighter is good, so I have equipped a batch of them. The typical export is for domestic sales. This batch of air force’s own equipment is given the number of J-7 2M.
As with the exported J-7M, a large amount of Western avionics is also used, and the combat effectiveness has been greatly improved. This batch of electronic equipment was introduced in the early 1980s. Therefore, now this J-7-2M can be exchanged. Let the technicians here disassemble and study carefully.
If you can produce it, you can imitate it yourself. If you can't produce it, you can import it from abroad. This refitted fighter can give them a lot of inspiration, let them shorten the research and development time, and satisfy the people of the date palm.
As for another J-7E, the biggest inspiration is its double delta wings and front-edge maneuverable flaps. The adoption of this type of airfoil greatly improves the maneuverability of the aircraft. Qin Guan said that it can be used in close combat. Comparable to F-16, this airfoil is the biggest contributor.
At the same time, the integral fuel tank is designed inside the wing, which greatly increases the fuel capacity and improves the combat radius of the fighter, and it is also favored by foreign customers.
The use of the avionics of the F-7 2M and the airfoil design of the F-7 E can certainly meet the technological level of this era, and then quickly improve it.
If the J-7 MG is brought over, its electronic equipment will be too advanced and not of much reference value.
Now, facing the two fighters that have been "reconstructed", Qin Guan still feels very relaxed. Every time he enters the system, he starts to sneak in secretly. That is his own brain, he is acting like an outsider. .
Thinking of this, Qin Guan felt that this fact was too strange. If he opened up a little more, everything would be resolved. In reality, there is a beautiful, gentle and lovely wife, and a bold and open Lisa in his brain. If he can Accept, what are you afraid of?
Besides, I’ve been a monk for a long time, and I’m in the world of my brain. That’s yy, right? What are you afraid of?
This thought, of course, just flashed past. Qin Guan once again strengthened his conviction, and he was not allowed to derail mentally. He was principled.
Wait, what else seems to be forgotten?
Aeroengine turbine single crystal air-cooled blades!
I've been boasting Haikou for a long time in front of the people of Niu Country, and now, the people of Niu Country are here for this.
It can be said that if it proves that it has this technology, then Niu Guoren will definitely not stumble again in order to obtain this technology, Nasbay’s improvement, and cooperation with other projects. If it proves that he is bragging, That one's international reputation will be greatly reduced.
This problem has reached the point where it must be solved, and the solution is that he could go to the weapon cemetery and weapon data cemetery to look through it.
But now, when I think about going in, I am entangled by Lisa. Every time I add a new mental power, I will face new problems. I will continue to upgrade the system in the future. I don't know how much headaches will be.
At the same time, Qin Guan cannot be said to have developed it himself. After all, if this thing is the most professional talent, Qin Guan can name it, but cannot become the person in charge of this kind of project. Otherwise, the other party does not doubt, is it a fool?
Qin Guan, originally a worker in a tank factory, provided a few good ideas, then copied a heavy truck and became the director of the factory. Because of his active mind, he was promoted by his superiors to engage in import and export trade. Can be explained.
But if Qin Guan is actually an expert in engines and an outstanding material expert, it would be nonsense.
For this project, a person must be brought out, who should I look for?
There was a person in Qin Guan's mind.
Academician Zhang Litong.
This is a lady, her contribution to materials, she writes about the unshakable spirit of women. She was born in 38 years, and was admitted to the Thermal Processing Department of Beijing Institute of Aeronautics and Astronautics with her first choice in 56 years. In 58 years, she was adjusted to the Department of Thermal Processing of Northwestern Polytechnical University to study casting with the national department. .
She has been dealing with materials all her life. The most recent outstanding contribution is that in 1976, she successfully overcome the high temperature deformation problem of corundum shell that has plagued aviation investment casting production for more than ten years, and has researched and developed insulation shell technology and low thermal stress. The casting process produced the first blade without margin in Han.
(Explain a little bit, the professional name, no margin, corresponding to the margin, the blank of the blade is first precision-casted, and after the precision-casting, it needs to be slightly larger and processed on the lathe. This is the meaning of the margin , And no margin refers to the shape you need directly after precision casting, without any reprocessing.)
The research of Academician Zhang Litong is now closely integrated with the Spey Project. In history, in 1980, under the guidance of Zhang Litong’s scientific research theory, Han State used Tongchuan Shangdian soil shell material to cast the first batch of high The precision and low roughness of Spey low-pressure one-stage hollow guide vane without margin.
The dimensional accuracy and internal quality of the newly cast blades are equivalent to those of the Spey engine blades of the internationally renowned Rolls-Royce Engine Company, and the surface roughness is slightly lower than that of the British blades.
This is also the breakthrough that Rolls-Royce did not provide these production technologies and was forced to conduct research in China.
Zhang Litong’s research on "no margin investment casting technology" has not only pushed Han's investment casting level to the international advanced level, but also laid a theory for the development of Han's new engine complex internal cavity blades and thin-walled complex integral components And process foundation.
These blades are all the compressor blades in the front, and now, what Qin Guan needs is the turbine blades in the back. This thing is the most bluffing.
Increasing the temperature of the turbine is a direct way to increase the power of the engine, and the temperature of the turbine depends entirely on the issue that the turbine blades can withstand and the material of the turbine blades.
It's time to visit Academician Zhang Litong.
Without further ado, Qin Guan called Tu Lao and the others. They looked at these fighters that had been "reconstructed" by Qin Guan, sparks flashed in their eyes, and after Qin Guan confessed, they left.
Professional things are left to professional people, and I am just a guide.
