"Uncle Yan, you are really amazing!" Lin Mo was greedy for these collections, and it took a long time to come back to his senses, and he couldn't wait to pack them all up and leave.

"It's not powerful, it's not powerful, I rely on this to eat, it's not only my job, but also my hobby, when I was engaged in J-10, I dismantled several foreign fighters as a reference to only screws and rivets, and used supercomputers to calculate the aerodynamic layout, at that time, when the Galaxy giant machine just came out, there was a period of time dedicated to this work, accounting for the cost of electronic equipment, at that time, a large number of people often didn't close their eyes for a few days and nights, eating and living in the hangar, I don't know how many sheets of drawing paper are used. Uncle Yan recalled the original years, and his eyes were shining again, shaking his head: "It's not easy, there are so many models, and one or two are finally set, I don't know how many good models have been sealed, it's not that it's not bad, but it can't be made." ”

"Uncle Yan, can I see these abandoned model designs?" Lin Mo's eyes lit up and said, this trip to these advanced models is his biggest purpose.

"Well, the general surname is not allowed to be seen, but your level of secrecy should be enough, come, I'll let you see my life's work, of course, not all of it, what can be shown to you can be semi-public, the real secrets are all handed over when I retired, and I didn't leave a picture."

Uncle Yan also saw the conversation between Lin Mo and Chen Haiqing, who was wearing anti-lotus clothes, and also confirmed Lin Mo's identity, generally speaking, this kind of drawings are useless even if they are leaked, they are all eliminated products more than ten years ago, and there is no value in analysis and manufacturing when they are used, and the reason for secrecy is to let some people who love to show off use it to show off, causing a bad impact.

Uncle Yan's collection is extremely well maintained, and there is not even a trace of dust, which opened Lin Mo's eyes, and he even saw a confidential model that has not been disclosed to the outside world.

"Come on, help me move these books, this is my family, basically the essence is here!" Uncle Yan turned out several thick books with a size of nearly half a square meter, the cover was obviously handmade with three box boards, and the inner pages were bound with thread on thick paper, which was completely handmade.

The weight of the books is obviously not light, each one weighs nearly twenty pounds, Lin Mo helped Uncle Yan put these books on the square table where the customer dined, and spread the entire tabletop.

Uncle Yan opened the thick book marked with the words second-generation fighter, and said to the drawings on the previous pages: "See, this is the second-generation aircraft of the same level as the J-8, JT-805, JT-809, T refers to the meaning of testing, the first' 8' refers to the improvement on the basis of the Xing energy of the J-8 now installed, or the continuation of the improvement of the MiG aircraft, now people will say that our old bones are conservative and will only copy the things of the Soviets, but at that time, our aviation industry was poor and white, there was nothing, only the Soviets were willing to support our aircraft and technology, and wanted to learn from Europe and the United States, but the technology blockade of people could only rely on the group of people who came back from studying abroad to lead the team, little by little continuous experiments, and sometimes even the data filled in with human lives, during that time the family was poor, and there was a famine, and they could not afford to invest fundsDo you know that at that time, the development of the atomic bomb accounted for nearly one-third of China's annual Jun fee, as well as ships, light and heavy weapons, single bingbing equipment, all kinds of large and small electronic equipment, which research institute is not all waiting to be fed, competing for so much experimental funds, even less when it comes to our aircraft design, self-defense counterattack war, we can hardly take out any decent fighter to participate in the war, There are only some old planes left that have participated in the War to Resist US Aggression and Aid Korea, and they are always dropping. ”

Uncle Yan uncovered a piece of historical truth for Lin Mo, and that hard time still makes Uncle Yan sigh.

"Of course, the J-10 before and after several versions that have been applied are not on it, I believe you should also go to understand, let's take a look at the third generation, but it is at the same level as the J-10." Uncle Yan, an aircraft design expert, explained to Lin Mo that every drawing that is extremely detailed will not make people dizzy and boring, and behind each drawing is a point of sleepless hard work.

"The third generation is the most practical one, basically we didn't completely copy the Russian stuff, at that time our conditions have been much better, there are more materials and funds to invest in my own design, the application of a lot of design is the technical reserves that we have accumulated in difficult times, now many accessories on the aircraft have been able to achieve self-production, but the motivation has to wait at least a few more years, you look at this, JT-1015, swept deformation Ji, with reference to F-there Tomcat pseudo-semi-semi-Ji, The fuselage adopts a stainless steel structural frame, but it is limited to the stability of the bomb after the bomb loading, and finally gave up, and there is also the JT-1055 folding machine, which is used for the short-range take-off and landing model of the aircraft carrier, which can adapt to the take-off and landing distance of 200 meters, and may also need the assistance of steam catapult, hehe, they are all cǎo diagrams, and the more important drawings are not allowed to be brought out, and they are still in the confidentiality period, these are all hand-drawn by me after I retired. ”

Uncle Yan flipped through the back books again, and said with a little ostentation: "These books are really good things, the fourth-generation fighters under development in China are still in the process of finalizing the details, and I have not been able to bring out many valuable drawings when I retired, so I only have a few unimportant experimental models here that are not important, and I have fantasized in my mind after retirement, and the latter few fifth-generation fighters, sixth-generation sub-aerospace fighters and seventh-generation space fighters, but none of them have been verified by the actual wind tunnel." ”

There is actually such a good thing, Lin Mo couldn't wait to open it, the imagination of the body shape on it is more and more amazing, and Junmi on the market will never see this kind of real fighter design.

The fifth-generation JT-32 "trapped." "It is not a design system at all with the fourth-generation J-20, and the physical fitness of the pilot is directly on a level, and the speed has even reached 3 times the speed of sound, which also has a core overload cockpit design concept, the sixth-generation JT-27 "Aurora", JT-30 "White Tiger", JT-33 "Dragon King". In addition to the "Fire Dragon" that is already in the middle of the opening, Uncle Yan still took out the upper cǎo diagram on paper, only the text description of the physical power, xing energy parameters and electronic design of the aircraft, but you can still see the design concept of adding deformation models from the sixth generation fighter.

The stealth function has been used as a basic function since the beginning of the fourth-generation fighter, with low presence, high speed, high maneuverability, high cruise and high life support rate, so that the fighter has a new positioning, and it must have the ability to return to battle with injuries and one-to-many group fights at any time.

The seventh-generation sci-fi version of the S-10 "Tianlong" air-space destroyer completely dragged the concept of an intra-atmosphere fighter aircraft, integrated interception, bombardment and stealth reconnaissance, high range, and greatly enhanced defense, and put forward the concept of a separate friction safety protection cockpit, it can be seen that there is also a faint design prototype of an air and space aircraft carrier and an air and sky port behind it, and perhaps the seventh generation fighter will begin to take shape in a few decades.

Yan Lao yézi's hands are not only limited to fighter planes, but also a lot of helicopters, bombardment aircraft and special-shaped aircraft design, all of which are usually accumulated creative ideas, designers do not only use limited fighter designs, sometimes one or two derivative special ideas will pop up, it is a pity to abandon them, and simply keep them.

There are many graphics that only exist in the mind, but if a professional designer marks the simulation data one by one, if you don't know it, you may think that it is true.

"That's a good thing!" Lin Mo brought a single-lens reflex camera and adjusted the resolution to the maximum, I can't say, this is still the golden dragon conjured up by the "invincible rabbit." "The different refractive indices of the transparent metal make the lens structure very different from the original, but the imaging effect is still the same.

Without any pre-charged flashes in the living room, high-resolution photos are stored and naturally sorted by the golden dragon.

Uncle Yan, who let Lin Mo take pictures, helped Lin Mo take pictures, and said with a smile: "Xiaolin, are you interested in being an aircraft designer?" If you're interested, I can teach you!"

Being able to fly an airplane and design an airplane, design and use are integrated, it is a perfect partner, Uncle Yan felt that this was definitely a good idea, and couldn't help but say it.

Lin Mo tilted his head and thought about it for a while, but he could only say helplessly: "Alas, but I'm a fighter pilot now, I'm afraid I can't do it, I'm afraid I can't sit still, and I feel a little dizzy when I see all kinds of complicated calculation formulas." ”

"What's so difficult about designing an airplane, I never think it's difficult, as long as there are enough materials to test, Shen Mi won't feel bored in it, think about others flying in the sky with their own design of the plane, just like they are driving? Xiaolin, how can you know that it is difficult if you don't try? I'm a professor, and I don't want to teach it. ”

Limited to the principle of work confidentiality, Uncle Yan must be tight-lipped about his original job, usually can not speak at will, the high-tech technology full of his head is limited to physical decline and old age and illness, there is no fǎ to return to the original job, can only hold back in his heart, I don't know how much depressed, finally met a pilot with enough secrecy to talk about some content that is not very secret, just like pretending to be deaf and dumb for several years, and suddenly can speak freely, Uncle Yan feels comfortable like never before.

ps: On the last day, the monthly pass is cleared, qiu rewards, and the back is more exciting, help me to publicize it first!。
