Chen Haiqing rushed to Hainan in a hurry, and opened up the relationship and was able to enter the newly built aircraft carrier fleet of the South China Sea Fleet, if he was one step slower, he was afraid that Lin Mo would be picked up by Shen Fei's people.

Chen Haiqing's worries were undoubtedly correct, it happened that he came in time, Shen Fei's engineer was really uneasy and kind, and openly invited Lin Mo to be a guest.

If it really makes people run away, will the national defense star be mixed in the industry in the future?

"Uh-huh, uh-huh, I think about it!"

Lin Mo rubbed his chin and considered, there are indeed a lot of good things in his hands, and they are all around fighter jets, during this time of following Shen Fei, although Shen Fei picked up a technical expert for nothing, it also made Lin Mo gain a lot.

Chen Haiqing is look forward to it, he knows that his brother is really expected, otherwise how could he not be predetermined by several major domestic aircraft designers to go after retirement, when Lin Mo can no longer fly, he has to go to work in the aircraft design institute that finally won him.

In the battle for talents, the 611 Institute has a big chance of winning, Lin Mo drove the J-1 is developed by the 611 Institute, and his mentor is also a retired expert of the 611 Institute, there is no doubt that Lin Mo has been branded with the innate imprint of the 611 Institute from his bones, which is simply a natural lineage.

Since the "demon" design drawing came out, it has strengthened their confidence in competing for Lin Mo, and even put the competition plan in the future development plan, not planning to be so cheap 611.

"I said, how many good things you have poured down, I can take them out for my brother."

Looking at Lin Mo's very promising appearance, Chen Haiqing was anxious.

As soon as he was negligent, a lot of techniques let Shen Fei dig away, but he was in a hurry, the old man at home spoke, if Lin Mo was poached by Shen Fei, he, the future general manager of the national defense star, would wait to be laid off directly.

It's still going to take over, no need to talk about it!

Let's work hard for someone else to get started with the children of the working class.

That's tantamount to cutting off your own financial resources!

I am also used to being extravagant, just relying on the little pocket money of my parents, where can I afford the expenses, not to mention that there are rules in the family, if I want to buy a house and a car, I have to earn it by myself, and the luxury goods bought by the family will be all recovered after marriage, unless I pay seventy percent of the cash to keep, otherwise I will wait for the tragedy.

If you can't bear the pressure of this status, you have to be deprived of all the superior living conditions, and you have to work hard like ordinary people to earn some living money, which is the superior and inferior.

Rather than not being able to adapt to the feeling of loss from falling from a height, it is better to be prepared to adapt to the life of the bottom society as soon as possible.

"Well, I have some alloy formulas that can be used in fighter jets, do you want them?"

Lin Mo still hid his hand and didn't give Chen Haiqing too many surprises.

"Recipe?" However, Chen Haiqing was not as Lin Mo imagined, but the surprise on his face was even stronger, he danced with his hands, shouting, "I want, I want, I want everything!" Hahaha! Just know that you must have something good. ”

His arm flicked and hooked directly on Lin Mo's neck, this time, he couldn't let him go.

Alloy is a substance with metallic properties that is synthesized by two or more metals and non-metals by a certain method. It is generally obtained by melting into a homogeneous liquid and solidifying. According to the number of constituent elements, it can be divided into binary alloys, ternary alloys and multi-alloy alloys.

Alloy formulation? This kind of thing is not worth anything to Lin Mo at all, there is a gold-based dragon that feeds on metal by his side, as long as this guy is willing, he can combine countless alloys with metal composition ratios at will, and it doesn't take any effort at all, it is more convenient than a special alloy metallurgical furnace.

Alloy trial production, even the proportion of 1/10,000 will cause different properties of alloy properties, such as stainless steel, according to the alloy composition of chromium, nickel, manganese, molybdenum, titanium, niobium and copper and other elements can be divided into 200 series, 300 series, 400 series and 600 series.

There are 90 kinds of metals in nature, and if they are arranged and combined, and the proportion of the ingredients is added, there are literally countless kinds of alloys.

Especially in the military industry, special alloy formulas are basically secrets.

Screening out valuable alloy types from a large number of alloy formulas requires not only a huge investment of money and equipment, but also a lot of manpower to conduct countless tests to have an alloy formula library.

And this database often represents the foundation and confidence of a country's industrial system, including the military industry, and the material application of all metal industrial products is based on this database.

Just like the MiG-25 "Flying Fox", a large number of stainless steel materials are used, and in the early days of equipping the Soviet army, with its extremely high performance parameters, it has been concerned by the Western world, and it is even speculated that the military aviation manufacturing technology of the former Soviet Union has been ahead of the world.

It was not until September 6, 1976, when Soviet pilot Lieutenant Belenko defected to Japan in a MiG-25 "Flying Fox" aircraft, that the Western world really unveiled the mystery of the aircraft.

Technical experts from the United States and Japan completely dismantled the MiG-25 "Flying Fox" and transported it to the Baili Air Base, more than 100 kilometers north of Tokyo, after a thorough inspection, 70% of the parts of the aircraft are stainless steel, although the limit speed is very high, the technical performance is not as terrible as imagined, but this is also a technical victory brought by a special alloy formula.

The MiG-25 "Flying Fox" shot down all kinds of fighters during its service, and there is even news that the MiG-25 shot down the US F-*** Wasp fighter during the first Gulf War.

As the future successor of the national defense star, Chen Haiqing certainly knows the importance of alloy formula for fighter jets, and this is not as simple as improving the strength of the fuselage and replacing the original aluminum alloy material.

Especially when the speed of the fighter reaches more than Mach two, the fuselage material has to face the threat of a "thermal barrier".

When the aircraft flies at supersonic speed in the dense atmosphere, the temperature of the aircraft skin will rise sharply with the increase of supersonic speed due to the heating of the shock wave and the high-temperature compressed gas between the body and the air, and the structural and material difficulties caused by aerodynamic heating.

At Mach 2, the temperature at the nose of the aircraft is slightly more than 100 degrees Celsius, but when it reaches Mach 3, the temperature on the surface of the aircraft will rise to 350 degrees Celsius, which has exceeded the limit temperature of aluminum alloy, making its strength greatly weakened, and at Mach 6, the temperature at the top of the aircraft has reached 1480 degrees Celsius.

The aviation industry calls the high temperature encountered by the aircraft when flying at high speed as a "thermal barrier", and it is also a hurdle that the aerospace industry must face.

It is not that the fighter is trying to pursue the limit, but it has to face one after another technology and material "roadblocks", and if there is no reasonable solution, the fighter will even be burned into a fireball in the atmosphere directly by its own speed.

The MiG-25 "Flying Fox" is precisely to break the conventional thinking of many people, using stainless steel as the main material, has broken a number of flight speed and flight altitude world records, can continue to fly at an altitude of 24,000 meters at a speed of Mach 2.8, and the maximum flight speed can even reach Mach 3, although it can achieve such performance, but the local temperature in the MiG-25 cockpit can even directly cover the eggs.

Although the performance brought by it was somewhat extreme and the balance was insufficient, it made the MiG-25 "Fox" one of the only three aircraft in the world to break through the "thermal barrier" at that time.

In addition to the MiG-25, the other two are the American SR-71 and the Russian MiG-31.

From wooden aircraft to aluminum alloy aircraft, from aluminum alloy aircraft to titanium alloy aircraft, every progress in aircraft materials means a big **.

Even if the current fighter generally uses titanium alloy, light weight, high strength, metal fatigue resistance, and stable chemical properties, but titanium alloy is not without defects, such as poor cutting performance, can only use laser cutting or one-time forming, conventional metal processing methods are not suitable for titanium alloy at all, more than 400 degrees Celsius will appear when the strength will be reduced, the impact of the "thermal barrier" effect will become more and more serious.

Lin Mo had already taken this "heat barrier" effect into account when building his "Demon Evil", and the gold dragon had enough alloy formulas so that Lin Mo didn't need to worry about the material under the "heat barrier".

It may be an insurmountable barrier for other aircraft design experts, but when it comes to Lin Mo, it is no longer a problem inadvertently.

In particular, some aviation parts suppliers, after getting Lin Mo's alloy formula, directly started production, they are not interested in knowing where the customer's formula comes from, which also makes the outside world ignore Lin Mo's treasure trove to a certain extent.

But the material limitations are instinctive and effortless for the Golden Dragon, and Lin Mo has a large number of alloy formulas to choose from.

"I'll copy it to you when I go back, and I'll have whatever you want." Lin Mo held a treasure trove of alloy formulas in his hand, and he didn't know how many people he would envy, but he still didn't know the value of these formulas to the National Defense Star.

"Oh, great, great! Let's go, I'm in for a treat in the evening! Five-star hotel, our brothers, we have to have a good talk, by the way to learn from you to learn air combat technology, I heard that you have created a lot of tricks, but you can't hide your secrets. ”

Chen Haiqing patted Lin Mo on the shoulder, laughed heartily and dragged Lin Mo to the Mercedes-Benz commercial car.
