Chapter 973 This thing is really ugly
"Okay, my general, this matter is settled so far. There is still a long time. We need to find the next opportunity. We need our white gloves to prepare for action. How to find these opportunities is what you need to pay attention to." The civil servant raised the coffee in his hand, signaled to the general, and took a sip.

"Mr. Gao, there is a comrade who is looking for you."
While Gao Zhendong was writing the steel material manual with several comrades, a comrade from the inner security brought two comrades to come over.
Those who can find their own office directly are likely to come from the Defense Working Committee, and the other party must have undertaken very important tasks.
Gao Zhendong asked the comrades from the Third Branch Factory to leave first. Anyway, the steel manual is not in a hurry. Now the third branch factory, the third rolling factory and the Beijing Steel Factory are still trying hard to verify it. It is because they feed too much at once, and it feels a bit like they are being supported.
As soon as the visitor opened his mouth, Gao Zhendong remembered the old Duan of the Northeast Carbon Research Institute who had not seen him for a while. In the past year, he had never seen him except for receiving his stuff during energy savings.
The accents of these two visitors reminded him of this man from Northeast China. As for Mr. Wang from Northeast China Aviation and Development Institute, he is not from Northeast China, not this accent.
"Hello, Chief Engineer Gao. This time we came here to imitate the MiG-21." The person who came was named Huang, who was one of the people in charge of the MiG-21 imitation.
Gao Zhendong was overjoyed when he heard this. Finally he started? As far as I know in my previous life, the imitation of MiG-21 should have started last year. It is unknown why this line is a little late.
"Welcome, please sit down for two." Gao Zhendong turned around to make tea, and Mr. Huang's next words made Gao Zhendong understand that he was wrong.
"This time we got the MiG-21 prototype, kit and information, and it took a lot of time to digest and absorb, so the overall work has only started now, and we are here to visit you."
It turned out that the plane entered the imitation very quickly in the previous life, but the main reason was not good news. Whether it was the aircraft kit we ordered or the complete set of technical information, the Russians did not give it all, because they were swallowed up due to the deterioration of their relationship.
This made the MiG-21 imitation begin when there were only a small number of prototypes, kits, and extremely lack of information.
Since there is not much to learn, it is definitely time to enter imitation. Enter imitation as soon as possible, and you can figure out the doorways and twists inside as soon as possible. By 1965, you can imitate this aircraft and create a prototype.
Under such harsh conditions, this speed is not uncommon, but there are many things in the process that can only be copied by comparison, and the principles are generally not clear.
In fact, it was not until the 1980s that we really understood the MiG-21, but the daylily was cold at that time, and the sky was already dominated by the F-15, 16, 18, Su-27, and MiG-29.
But this life is different. For various reasons, the Russians were very realistic this time and handed over all the prototypes, kits and technical materials intact, which made the Northeast man in charge of imitation fall into the trouble of happiness.
There are really too many.
You should know that even the line that Gao Zhendong knew in his previous life, we were self-reliant in the face of extreme lack of data, and we made a total of 26 new alloys, coatings and other new materials, and tested and mastered 46 new technologies and new processes, as well as titanium alloy integrated molding and other technologies, so that we made the plane stumbling and not very good.
It is conceivable how much energy and time it takes to digest a complete set of information.
It can be said that this is already very fast. For the real work in the future, it is effective that if you want to do it well, you must first sharpen your tools.
"Oh, that's amazing. This plane should be much more complicated than the MiG-19, right?" Gao Zhendong pretended not to know.
"Indeed, it's too complicated, and it took us a lot of time to basically understand. The current situation is like this. If we want to copy it in a straightforward manner, we have basically met the conditions for copying it. We are even already carrying out some of the work that can be carried out in the early stage."
The Northeast uses the same method of digesting and preparing while digesting some preparations, and mobilizing aviation-related factories across the country to complete this matter together. The preliminary work is relatively fast.
After all, no matter how complicated the MiG-21 is, it is still a second-generation aircraft, and its complexity is limited compared to the later aircraft.
"In other words, if you want to copy and copy it, it will be very fast?"
"Yes, because there is a full set of data and a large number of prototype kits, this is a bit different from surveying and mapping and imitation, and it is much faster."
The most important thing to do when surveying and mapping is to make a living, and they often turn around and start over because they know it but don’t know why.
"What is the decision about imitation now?" Gao Zhendong asked with a smile. Since Mr. Huang specifically mentioned "if he imitated it in full", it means that there must be other options behind it. After all, when he decided to imitate the MiG-21 as an interceptor fighter, Gao Zhendong put some hooks and baits.
"I haven't decided yet and I'm soliciting opinions from all parties." Mr. Huang also smiled and was very happy. Everyone likes to do multiple-choice questions with better guaranteed options. At worst, they just copy them all. Anyway, the MiG-21 is not bad. This is 62 years, and the MiG-21 looks really good.
After saying that, he introduced: "Actually, after digesting the technical information of the R-11F300 engine of the MiG 21F, our comrades at Northeast Aviation and Development Institute clearly stated that they are sure to increase their thrust by at least 10%. In this way, we have more ideas and are greedy, haha."
"Are you going to do it higher and faster?" Gao Zhendong said with a smile.
"No, no, no, we think the double 2 interception indicator you proposed at the meeting was enough. What we thought was to use these increased thrust to improve other performance. For example, climb rate, acceleration, etc., as well as airborne equipment, after all, the performance of an aircraft is not just as simple as extreme speed and altitude. As for altitude and speed, it is enough to increase as much as possible under the premise that these can be met, at least as long as it does not decrease."
It seems that Mr. Huang and his team have also thought about it carefully and comprehensively studied it, and they have considered it thoughtfully in this regard.
In fact, after reaching a certain limit, it is very difficult to increase the extreme speed and altitude of the aircraft. Instead of increasing the extreme speed that can only fly with a little bit of force, it is better to convert the engine's improvement to other capabilities.
When many aircraft are improved, although the engine thrust has increased a lot, the altitude and speed are still the same. This is why.
"Mr. Huang said very well." Gao Zhendong said with a smile.
"Mr. Gao, I remember when planning the fighter's third-level fighter type, you said that the MiG-21's nose space can be greatly expanded without much affecting the aircraft's speed and air intake, right?"
Mr. Huang’s purpose is mainly this.
The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!
Gao Zhendong nodded: "Yes, that's the case."
Mr. Huang smiled and said, "That's great. Mr. Gao, you don't know. Although the new radar you and your comrades are working on, we looked at the current parameters and were very envious. If we could install this thing onto the MiG-21, it would be the overlord in the air, at least in terms of detection. But when we looked at this plane, we really couldn't find a place to install it."
"Actually, my idea is mainly about the same idea now, and the specific one has not yet been deepened." Gao Zhendong said.
But Mr. Huang didn't care and was very happy: "Just think! What we lack now is ideas. It is not that difficult to implement specific projects. After all, we also have wind tunnels, detailed information, and combat-6 interception work experience. The idea is the most important."
As long as you have a technical route, you don’t have to worry about the specifics, and you can’t worry about it. After all, Gao Zhendong cannot enter the specific work.
"Okay, look, this is my idea." Gao Zhendong drew a schematic diagram of air intake on the paper. This diagram comes from the War-7FS type that did not continue to develop in the previous life. Although it did not continue to develop, this aircraft has a prototype, and completed all test flight missions, and obtained a large amount of flight data, proving that this road is feasible.
With the increase in engine push and the aircraft also gained weight due to various improvements, the overall flight performance of the aircraft remained unchanged, but some performances were greatly improved, such as the maximum climb rate increased by 40%, and the acceleration of Mach 0.6~1 was reduced by 20%.
While obtaining large noses, these improvements prove that this path is still effective. But when the test flight of this thing was over, the Tenth Master was almost alive, so the Air Force naturally didn't like it.
Looking at the graphics leaked by Gao Zhendong's writing, Huang finally understood that Gao Zhendong said at the meeting that "it's just a little ugly." This thing is really ugly.
"This F-8 Crusader who looks a bit like a Citiman, but the size of the air inlet and the ratio of the nose is more radical. We really didn't think about it in this direction. We always felt that it would greatly affect the aerodynamic shape of the aircraft, and we always felt that it could not be changed from the nose to the air intake to the jaw."
The air intake method has a bit large span, and the comrades holding a pure new machine did not dare to think about it there.
Laogang-5: Actually, it’s not that big.
F-8, Citigroup's carrier-based supersonic fighter, has a typical jaw-intake. If this aircraft is not very famous, most people don't know about it, then its son is even more famous, the A-7 subsonic attack aircraft.
Gao Zhendong smiled and said, "In fact, it doesn't have much impact. It's generally acceptable, especially if Aerospace Engine can increase the engine by more than 10%, then there is even more hope."
The size and details of the picture he drew were of particular importance. It was the result of his efforts to restore the proportion through various channels. Although it cannot be said that it is exactly the same as FS, at least there will be no problems in the general direction and it is very guiding.
