The lithium battery laboratory does need to make a dedicated laboratory, because this experiment is too dangerous.

Even many lithium battery laboratories abroad often catch fire and burn, and everyone knows that once lithium batteries burn, they cannot be extinguished at all.

Therefore, it is necessary to make a safer laboratory, and the only way to burn a lithium battery is to throw it into the water, otherwise it will have to let it drain the energy in it.

Bangs decided to go directly to lithium iron phosphate, which would not be discovered until 1986.

In fact, there is a structure before lithium iron phosphate, that is, lithium cobalt oxide and graphite.

Although lithium cobalt oxide has great advantages, there is still a big disadvantage, the crystal structure of lithium cobalt oxide is easy to collapse, which causes the overall performance of the battery to fail, that is, the ability to store electrical energy is greatly reduced.

And the bangs are not sure, foreign countries now find that lithium cobalt oxide and graphite are not, so in order to avoid colliding with the other party, and directly ahead of the other party in technology, the bangs directly selected lithium iron phosphate.

It is precisely because of the emergence of lithium iron phosphate that semiconductors have developed by leaps and bounds, and semiconductor products such as mobile phones and mobile computers have swarmed.

"After the lithium battery is made, you can build a personal computer."

"Although you can get a personal computer now, it doesn't mean much, but you can do it in advance."

Liu Hai knows that the semiconductor industry in our country is also developing rapidly.

The main reason is that the use of semiconductors in the military is becoming more and more important, at the beginning is the tank night vision made by bangs, to the artillery radar in the back, and then to the CNC machine tool in the back.

The importance of semiconductors in military equipment is becoming more and more prominent.

By 2020, China's semiconductor technology is actually the world's leading.

Especially in terms of radar, it is ahead of both bald eagles.

Speaking of which, the main reason is that we overtake in corners in terms of radar, and we are directly on the active phased array radar.

Don't look at the old high jump of the three masters at that time, but as far as the castrated version of the weapons and equipment he bought, if he really wants to fight, it will be one-way transparent in front of us.

The various weapons and equipment of the fat goose bought by the three masters, the semiconductor technology of the fat goose itself is not good, take the radar in the fighter jet as an example, the fighter radar of the fat goose is the heaviest fighter radar in the world.

Not to mention all kinds of other radars, if you really want to open the film, all kinds of electronic means will rush up, and the other party will be blind.

Don't look at the fat bear, blowing their own early warning aircraft to the sky, but in terms of their semiconductor technology level, Liu Hai feels that there is a lot of moisture in data optimization.

Of course, the data optimization of weapons and equipment is not only done by fat bears, but also by bald eagles.

Bald Eagle even optimized his own submarine data, and when we understood it later, he made the submarine designer cry and laugh, always thinking that he couldn't do it, but he didn't expect the other party to fake.

The steel of the aircraft carrier is the same, we can't reach the level that the bald eagle said, and finally found out that the bald eagle has optimized the data, who can get this thing.

There is also a small book of various steel data optimization.

The world's most advanced electronic warfare aircraft in 2020 are only us and Bald Eagle.

"When are you going to study the Growler's various electronic pods and write a plan?" Bangs had a plan in his heart.

The Growler electronic pod, the most advanced electronic warfare aircraft of the Bald Eagle.

"When our big plane is doing a long-range experiment, we have to fly to Hainan, and the superior leaders want to see this big plane." Sun Aiguo's eyebrows fluttered when he said this.

"No problem, I've looked at the flight test records of the aircraft, and there is no problem for the time being, and the possibility of problems in the future is very small."

"Compared with foreign medium-sized transport aircraft, our medium-sized transport aircraft has reached the world's advanced level, and even leads the world." Sun Aiguo nodded.

"It's still thanks to other brother departments, especially the aircraft girders that Erzhong made for us." Liu Hai nodded, aircraft manufacturing, originally a multi-departmental collaborative project.

"Yes, some parts of our fighter jets also use double die-casting equipment, which greatly reduces the weight of the fuselage and strengthens the structure of the fuselage." Sun Aiguo said again.

"However, there are still many medium and large transport aircraft abroad, and we still need to work harder." Of course, Liu Hai knows that we are almost the same in medium-sized transport aircraft, but it is much worse than various large transport aircraft.

Especially in the case of AWACS, AWACS requires a larger platform for transport aircraft, and the same is true for tankers.

"Take your time, large and super-large transport planes, we can always catch up step by step."

"The military strength of the fat bear and the bald eagle, as well as the overall scientific and technological strength, are too strong."

"However, it is not easy for us to develop to this day, and we have taken a shorter time, I believe that in the future, we can surpass the fat bear and the bald eagle on the big plane." Sun Aiguo said confidently.

Liu Hai nodded silently when he heard this, thinking of the series of transport planes of the fat bear next door, and he also felt big.

Historically, in 2020, we have not caught up with the current fat bear in these fields.

For example, the maximum take-off weight of the An-22 aircraft that was discontinued in 1974 can reach 250 tons.

Not to mention the An-124 in the back, the classic in the An-225 series.

"I still have to find a way to dig the corner of the fat bear." Of course, Bang Hai knew that he couldn't make these things, because there were no ones on the aircraft carrier.

Of course, I can also concentrate on research, design, according to my current knowledge level and all kinds of knowledge learned on the aircraft carrier, I am afraid that I can work out it in 20 years.

Why do you say that it will take 20 years, it is because at this stage, Liu Hai is the only one who can develop this kind of aircraft.

In the first 10 years, it is necessary to train all kinds of technical personnel, and it may not be possible to train them in ten years, because the design of these large aircraft may not be able to be learned in 10 years.

Then he led the team to develop and manufacture large transport aircraft in the 10s.

The biggest gap between us and the fat bear and the bald eagle is the gap between the top talents.

In several aircraft design and research institutes of Fat Bear, there are a lot of top aircraft design talents, not to mention middle and lower-level designers.

And what about us?

The gap in talent is the root of the gap in science and technology, and it is impossible to say that Liu Hai will put 20 years on a big plane.

There are still so many good things on the aircraft carrier that you don't take out, and there is no point in smashing the big plane.

And to be honest, large transport aircraft are not as important as this aircraft carrier.

Then the only way is to dig the foot of the wall.

Sun Aiguo chatted for a while and left, and Liu Hai also had some miscellaneous things in his hands, that is, the dealer had a few superyacht orders.

And Liu Hai also heard that the customers of the three masters no longer want to order superyachts, but Niu Niu does not refund the deposit.

Anyway, the three masters are making a big deal with Western countries now, and Liu Hai can also understand the current mood of the three masters.

Whoever changed wanted to eat a mouthful, but I didn't expect to lose my wife and break the army, besides, the things given by the fat bear are so fragrant, the more they have trouble with the West, the greater the support of the fat bear.

For the fat bears, it is also in their national interests to get closer to the three masters, so it is understandable to vigorously support the three masters.

However, the design of superyachts is relatively slow, because it is necessary to communicate, the buyer puts forward his own design requirements, and the bangs design the appearance that meets the buyer's requirements, and then the color ratio, interior decoration style and so on.

However, Bangs spends more time pondering the Super D helicopter.

Bangs found the engines of two Super D helicopters on the aircraft carrier, as well as various other accessories.

All aircraft engines have a lifespan, and when the life is up, the only way to do this is to replace them with new ones.

Of course, Liu Hai also has other regulatory tasks.

In mid-January 1978, the Yun-9 aircraft flew from Kyoto to the test flight site of the motorcycle factory in Hainan.

The whole journey is about 3,000 kilometers, and the maximum range of the Yun-9 aircraft can reach more than 5,000 kilometers.

The higher-level leaders sat in wheelchairs and held binoculars from afar, accompanied by other retired veteran cadres.

Needless to say, when a loud sound came from the sky, these old cadres picked up the binoculars in their hands one after another.

Under the watchful eyes of these veteran leaders, the Yun-9 plane successfully landed at the test flight site here.

After the plane landed and went through a preliminary inspection, the superior leaders outside the safe area brought the veteran cadres to see the Yun-9 plane.

The Yun-9 aircraft directly lowered the rear hatch.

"Okay!"

"Okay!" The superior leader was in a wheelchair, and was pushed by the staff to enter the cabin through the back door, looking at the wide cabin, and the superior leader also clapped and praised at the same time.

The other veteran comrades were also thrilled when they looked at the spacious cabin and the huge plane.

These veteran comrades all came from a difficult era, and they couldn't help but sigh in their hearts when they thought of wearing straw sandals and using old sleeves.

A group of old comrades were in this cabin, touching here and there, looking at this huge cabin, and the technicians were on the side to introduce it.

I heard that this plane can transport more than 100 people and related weapons and equipment at a time, can carry up to 30 tons, and can fly up to 5,200 kilometers at a time.

A group of old comrades visited the cabin and expressed their condolences to the crew members, and then took a group photo with the big plane on the runway.

After some things were put down, the superior leaders thought of the other people they had met in their lives, their former lovers, their former comrades-in-arms, their former family members, and when the country was established, these lovers, comrades-in-arms and family members left early.

The higher-level leaders decided to look at the development of the country with their own eyes, and wait until they go to another world in the future, so that their former lovers and comrades-in-arms can tell about the development of our country. (There are some things that I can't write too much, so I will mention them vaguely, so please forgive me.) ）

and live up to the new world they have forged with their lives.

Therefore, when the superior leaders came to Hainan for recuperation, they listened to the doctor's exercise more, smoked less and did not drink, and their physical condition was getting better and better.

In the winter, you can recuperate at a sanatorium near the sea, and in the summer, you will go to a summer resort in the mountains.

The Yun-9 aircraft will conduct a series of test flights at this test flight site.

Then it will go to the plateau airport, and in the summer it will go to some Gobi airports in the north, and basically complete all the tests in the summer of '78.

At the end of January 1978, 10 containers were delivered to Liu Hai's personal museum.

This is the old object that the gold division of bangs was exchanged for.

As for whether these old objects are from the private products of these nobles, or whether they are the bangs that were secretly changed from some place, it doesn't matter.

Liu Hai didn't get the list of these old items for the time being, because these things had to be identified one by one in front of the dealer.

If there is a fake, it must be changed, and the bangs don't believe in the dealer's character, in case these guys make some fakes to fool them, or the dealer doesn't know it.

This is the same as buying and selling, buying and leaving.

10 containers, 15,000 pieces of various old objects, all sorted and packaged.

It contains bronzes, porcelain, jade, ancient paintings, ancient books, etc., as well as some Western oil paintings and sculptures, but the number of Western oil paintings and sculptures is relatively small, less than 500 pieces.

And these things have to be professionally processed before they can be opened to the public, so Liu Hai didn't say that he was in a hurry, and he had to go to see it now, but it would disturb the other party's work.

"Big brother!" On January 20, 1978, the twelfth day of the twelfth lunar month, the big cold, the little junior brother finally got the midterm results and rushed into Liu Hai's office.

"Two 100 points." The little junior brother showed Liu Hai the two midterm exam papers of Chinese and mathematics.

"Count 20 little red flowers." Bangs pretended to look closely, and then said.

"Big brother, can you help me origami the paper airplane, the paper airplane I fold can't fly far." The little junior brother looked at the bangs with blank eyes.

"I'll teach you how to do it." For Liu Hai, who specializes in aircraft design and manufacturing, it is too simple to make a paper airplane that flies far.

In the era when the bangs crossed, there were paper airplane flight records abroad, some were in the air, and some were the flight distance.

Liu Hai took out a piece of paper and taught the junior little brother little by little.

After the little brother got the paper airplane, he ran outside to fly.

"Wow!"

"I can fly so far!" Soon there was a cheer from the little junior brother outside.

"Don't catch a cold!" Bangs shouted at the office door.

"Big brother, I'll go first, my mother asked you to come to the house for dinner in the evening." The little brother went back to the room and put on the padded jacket, then took the two paper airplanes and ran away.

Liu Hai is not worried about the safety of the little junior brother at all, because there is a special person to follow.

Bangs returned to the office and continued to design a new type of turboshaft engine, to be precise.

The engine design of the aircraft is one thing, but the more critical thing is the materials and manufacturing technology.

Without materials and manufacturing technology, even the best design will be reduced to a piece of waste paper.

The lithium battery laboratory has not yet been built, but Liu Hai has written some plans, of course, it is impossible to come up and take the research direction of lithium iron phosphate batteries, Liu Hai is still formulating some research directions according to some foreign papers.

On the one hand, it is necessary to avoid saying that you have found the right direction when you come up, and on the other hand, it is also to let the researchers in the lithium battery laboratory have a certain research foundation first.

The technicians of this battery laboratory are all in their own factories or universities, and they must first familiarize themselves with the research direction and related content of lithium batteries.

"Do you want to tape graphite?" Bangs thought of a Nobel Prize.

"Forget it for now."

"I'm not unfamiliar with this Nobel Prize, and I can exchange it for benefits." Bangs know what the Nobel Prize has a serious tendency to do.

"Forget it, wait two years and see, anyway, no one found out until 2004 in history, what if your son needs it then?" However, Bangs didn't plan to do it right away.

When he was about to get off work in the afternoon, Liu Hai first drove to the research room where Zhu Haiyang worked.

Then go to the teacher's house with the teacher for dinner.

"Didn't I go back to my hometown last year to donate money, and this year my hometown people sent a lot of things, and I came back to eat at home for a few days." Zhu Haiyang said to Liu Hai, who had just come in, while packing up his things in the office.

"Then I'm going to have to eat more." Bangs said with a smile.
