Return to the red age

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

Even many foreign lithium battery laboratories often catch fire, and everyone knows that once a lithium battery burns, it cannot be extinguished.

Therefore, it is necessary to build a safer laboratory. If the lithium battery burns, the only way is to throw it into water, otherwise it will have to let it discharge all the energy.

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

In fact, there is another structure before lithium iron phosphate, which is lithium cobalt oxide and graphite.

Although lithium cobalt oxide has great advantages, it still has 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 Liu Hai is not sure. Foreign countries have now found that lithium cobalt oxide and graphite are not available, so in order to avoid collision with the opponent and directly lead the opponent technically, Liu Hai directly selected lithium iron phosphate.

It is precisely because of the emergence of lithium iron phosphate that semiconductors have developed by leaps and bounds. Semiconductor products such as mobile phones and mobile computers have emerged in droves.

"After lithium batteries are developed, personal computers can be built."

"Although it is possible to build a personal computer now, it is not of great significance, but it can be done in advance."

Liu Hai knows that our country's current semiconductor industry is also developing rapidly.

The main reason is that the application of semiconductors in the military is becoming more and more important. At the beginning, it was the night vision of tanks made by Liu Hai, and later on the artillery radar, and then on to the CNC machine tools.

The importance of semiconductors in military equipment is becoming increasingly prominent.

By 2020, my country’s semiconductor technology is actually considered the world leader.

Especially in terms of radar, it is ahead of the bald eagle.

Speaking of this, the main reason is that we are overtaking in radar, and we directly went to active phased array radar.

Don't look at how high the Third Leader was at that time, but the castrated versions of the weapons and equipment he purchased would be one-way transparent in front of us if we really wanted to fight.

Among the various weapons and equipment purchased by the Third Master, Fat Goose's own semiconductor technology is not good enough. Take the radar in fighter jets as an example. Fat Goose's fighter jet radar is the heaviest fighter jet radar in the world.

Not to mention all kinds of other radars, if you really want to open a film, all kinds of electronic means will swarm at you, and the other party will be blinded.

Don't look at Fat Bear, who blows up his own early warning system, but given their semiconductor technology level, Liu Hai feels that there is a lot of data optimization involved.

Of course, the data optimization of weapons and equipment is not only done by Fat Bear, but also by Bald Eagle.

Bald Eagle even optimized its own submarine data. When we understood it later, it made the submarine designer dumbfounded. He always thought that he was not good at it, but he didn't expect that the other party was faking it.

The same goes for aircraft carrier steel. We couldn't reach the level that Bald Eagle said. Finally, we discovered that Bald Eagle had optimized the data. Who can come up with this thing?

There are also various steel data optimizations in the notebook.

The world's most advanced electronic warfare aircraft in 2020 is just us and the Bald Eagle.

"When will I study the various electronic pods of the Growler and then write a plan." Liu Hai had already planned in his mind.

The Growler electronic pod is Bald Eagle's most advanced electronic warfare aircraft.

"Our large aircraft will fly to Hainan when doing long-range experiments. The superior leaders really want to see this large aircraft." Sun Aiguo said this with great joy.

"No problem. I have read the flight test records of the aircraft. There are no problems 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.

"Thanks to other brother departments, especially Erzhong for manufacturing the aircraft beam for us." Liu Hai nodded. Aircraft manufacturing is originally a multi-department collaboration project.

"Yes, some parts of our fighter jets also use secondary die-casting equipment, which greatly reduces the weight of the aircraft body and strengthens the structure of the aircraft body." Sun Aiguo added.

"However, there are still many medium and large transport aircraft abroad, and we still need to work harder." Liu Hai certainly knows that we are almost there among medium-sized transport aircraft, but it is still far behind various large transport aircraft.

Especially in terms of early warning aircraft, early warning aircraft require larger transport aircraft platforms, and the same is true for tankers.

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

"The Fat Bear and Bald Eagle's military strength and overall technological strength are too strong."

"However, it is not easy for us to develop to this day, and it takes us less time. I believe that in the future we can surpass the fat bear and bald eagle on large aircraft." Sun Aiguo said confidently.

Liu Hai nodded silently when he heard this. Thinking of the series of transport planes of Fat Bear next door, he also felt a big headache.

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

For example, the An-22 aircraft, which was discontinued by Fat Bear in 1974, has a maximum takeoff weight of 250 tons.

Not to mention the An-124 and An-225 which are the classics among the series.

"We still have to find a way to exploit Fat Bear." Of course Liu Hai knew that he couldn't come up with these things because they didn't exist on the aircraft carrier.

Of course, you can also concentrate on research and design. Based on your current knowledge level and the various knowledge learned on the aircraft carrier, I am afraid that if you work hard for 20 years, you can come up with it.

Why does it say it will take twenty years? That’s because Liu Hai is the only one who can develop this kind of aircraft at this stage.

Various technical talents must be cultivated in the first ten years, and they may not be able to be trained in ten years, because the design of these large aircraft may not be learned in ten years.

Then he spent the 10s leading the team to develop and manufacture large transport aircraft.

The biggest gap between us and Fat Bear and Bald Eagle now is the gap between top talents.

Fat Bear's several aircraft design institutes have 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. Besides, it is impossible for Liu Hai to spend 20 years on a big plane.

There are still so many good things on the aircraft carrier, so there is no point in fighting against big aircraft.

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

Then the only way is to poach.

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

Moreover, Liu Hai also heard that Sandangjia's customers no longer wanted to order the superyacht, but Niu Niu would not refund the deposit.

Anyway, the Third Master is currently in quite a quarrel with Western countries, and Liu Hai can understand the Third Master's current mood.

It was someone else who originally wanted to take a bite, but he didn't expect that he would lose his army after losing his wife. Besides, the food given by Fat Bear is so delicious. The more the trouble with the West becomes, the greater the support of Fat Bear will be.

For Fat Bear, it is in line with their national interests for the third master to move closer, so it is understandable to strongly support the third master.

However, the design of superyachts is relatively slow, because it requires communication. The buyer puts forward his own design requirements, and Liu Hai designs an appearance that meets the buyer's requirements, and then the color matching, interior decoration style, etc.

But Liu Hai spends more time thinking about the Super D helicopter.

Liu Hai found the engines of two Super D helicopters and various other accessories on the aircraft carrier.

All aircraft engines have a lifespan. After the lifespan is over, the only option is to replace the engine with a new one.

Of course, Liu Hai also has other supervisory tasks.

In mid-January 1978, the Yinjiu aircraft flew from Kyoto to the motorcycle factory's test flight ground in Hainan.

The entire trip is about 3,000 kilometers, and the maximum range of the Y-9 aircraft can reach more than 5,000 kilometers.

The superior leader was sitting in a wheelchair holding a telescope from a distance. He was accompanied by other retired cadres.

Needless to say, when a huge sound came from the sky, these veteran cadres picked up the telescopes in their hands.

Under the watchful eyes of these old leaders, the Yunjiu aircraft successfully landed at the test flight ground here.

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

The Yunjiu aircraft directly lowers the rear hatch.

"OK!"

"Okay!" The superior leader was sitting in a wheelchair and was pushed by the staff into the cabin through the rear hatch. Looking at the spacious cabin, the superior leader also clapped his hands and praised.

The other old comrades also felt excited when they looked at the spacious cabin and the huge aircraft.

These old comrades all came from hard times, and when they think of wearing straw sandals with old sleeves, they can't help but sigh.

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

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

The old comrades present liked it more and more. A group of old comrades visited the cabin to express condolences to the crew members, and then took photos with the big aircraft on the runway.

After letting go of certain things, the superior leaders thought of other people they had met in their lives, their former lovers, their former comrades-in-arms, and their former family members. When this country was founded, these lovers, comrades-in-arms, and family members had long ago and left.

The superior leaders decided to use their own eyes to see more of the country's development. When they go to another world in the future, they can tell their former lovers and comrades about the development of our country. (There are some things that I can’t write too much about, so I’ll mention them in a vague way, so please forgive me.)

Nor will they live up to the new world they created with their lives.

Therefore, when the superior leaders came to Hainan for recuperation, they listened to the doctor's advice and exercised more, smoked less and drank less, and their physical condition got better and better.

In the winter, I recuperate in the sanatorium near the seaside, and in the summer, I go to the summer resort in the mountains.

The Yunjiu aircraft will conduct a series of test flights at the test field here.

Then it will go to the plateau airport, and in the summer it will go to some Gobi airports in the north. Basically, all the tests will be completed in the summer of 1978.

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

This is the old thing that Liu Hai got in exchange for his gold share.

It doesn’t matter whether these old items come from the private products of these nobles, or whether they are secretly exchanged for bangs from somewhere.

Liu Hai hasn't gotten a list of these old items yet, because these items have to be identified one by one in front of the dealer.

If there are fake ones, they must be replaced. Liu Hai doesn't trust the dealer's character. What if these guys get some fakes to fool them, or the dealer doesn't recognize them.

This is just like the buyer and seller, buy and leave.

10 containers, 15,000 various old objects, all sorted and packed.

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

Moreover, these things must be professionally processed before they can be opened to the public, so Liu Hai did not say that he was in a hurry and wanted to see them now. On the contrary, it would disturb the other party's work.

"Brother!" On January 20, 1978, the twelfth lunar month of the twelfth lunar month, the junior brother finally got his midterm results and rushed into Liu Hai's office.

"Two 100 points." The junior brother showed Liu Hai the two midterm exam papers in Chinese and Mathematics.

"Count 20 little red flowers." Liu Hai pretended to look carefully and then said.

"Brother, can you help me fold a paper airplane? The paper airplane I fold cannot fly far." The younger brother looked at Liu Hai eagerly.

"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 can fly far.

In the era when Liu Hai traveled through time, there were paper airplane flight records abroad, some of which were the time spent in the air, and some were the distance traveled.

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

After the junior brother got the paper airplane, he ran outside and flew.

"Wow!"

"You can fly so far!" Soon the cheers of the junior brother came from outside.

"Don't catch a cold!" Liu Hai shouted at the door of the office.

"Brother, I'm leaving first. My mother asked you to come home for dinner tonight." The junior brother returned to the room and put on his cotton-padded jacket, then said hello with two paper airplanes and ran away.

Liu Hai was not worried about his junior brother's safety at all, because there was someone following him.

Liu Hai returned to the office and continued to design a new turboshaft engine. To be precise, he copied it.

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

Without materials and manufacturing technology, no matter how good the design is, it will become a piece of waste paper.

The lithium battery laboratory has not yet been set up, but Liu Hai has already written some plans. Of course, it is impossible to just come up with the research direction of lithium iron phosphate batteries. Liu Hai is still formulating some research directions based on some foreign papers.

On the one hand, it avoids saying that you have found the right direction when you first come up, and on the other hand, it also allows the researchers of the lithium battery laboratory to have a certain research foundation first.

The technicians in this battery laboratory are all from our own factories or universities. We must first familiarize these people with the research direction and related content of lithium batteries.

"Should I use tape to stick graphite on?" Liu Hai thought of a Nobel Prize.

"Let's forget it for now."

"I don't care about this Nobel Prize, and I can use this in exchange for benefits." Liu Hai knew that this Nobel Prize had serious tendencies.

"Forget it, let's wait and see in two years. Historically, no one discovered it until 2004. What if my son needs it by then?" However, Liu Hai did not plan to do this immediately.

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

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

"Didn't I go back to my hometown last year to donate money? This year, people from my hometown sent a lot of things. I will come back to my house for a few more days to eat." Zhu Haiyang was packing things in the office and said to Liu Hai who had just come in.

"Then I want to eat more." Liu Hai said with a smile.
