Return to the red age

However, Liu Hai did not play this game, mainly because he was too busy. The two projects he was working on were both extremely important.

The first was the electronic system of the White Swan, and the second was the stealth fighter.

This time, Liu Hai took out two models, the first was the J-20, and the second was the F 35.

These two models have been made and have been sent to the wind tunnel in Changan for testing.

The transformation of the White Swan is also progressing in an orderly and continuous manner.

Along with the sales of the third-generation Panda computer, several computer companies were born around the world.

The largest of them is Motorola Computer Company.

Motorola's computers are also OEM, because Panda computers are assembled from various parts.

Chips, graphics cards, memory bars, hard drives, power supplies, circuit boards, monitors, and chassis.

Motorola directly uses these to assemble a computer, and then uses the Motorola brand.

And the manufacturers of these computer parts also gave Motorola some discounts.

This is also the general direction set by Liu Hai, that is, to cultivate more OEM brands.

These parts manufacturers of Panda computers have gradually shifted to upstream manufacturers, rather than directly selling computers.

Just like in 2020, although there are domestic brands of computers, the chips, memory sticks, hard drives and other parts used in them are all from abroad.

Liu Hai will follow this path in the future, that is, gradually give up the market.

In November 1995, two MiG-29 carrier-based aircraft of the third boss crashed during training.

A month later, the investigation report of the third boss accused the MiG-29 carrier-based aircraft delivered by Fei Goose of having major defects.

The third boss listed the various shortcomings of the MiG-29 carrier-based aircraft. The first is the short range, with a combat radius of only a few hundred kilometers.

Then the MiG-29 carrier-based aircraft combat vision is not good, because the MiG-29 is hunchbacked and it is difficult to see the situation behind.

What the third boss complained about most is that it takes 6 different buttons to launch an air-to-air missile.

Fei Goose certainly did not admit the accusation of the third boss.

Fei Goose accused the third boss of low quality of fighter pilots and did not meet the training requirements at all.

In just 4 months, the third boss crashed 10% of the carrier-based aircraft.

This number is amazing.

And according to relevant reports, the third boss encountered various accidents during the aircraft carrier combat training.

At this time, Liu Hai had already obtained the wind tunnel data of the two aircraft models.

Because the wind tunnel at Changan gave up other tasks and specialized in the two models that Liu Hai took out.

Not surprisingly, the wind tunnel data of the two aircraft models are extremely excellent.

Liu Hai chose the appearance of the J-20. As for why Liu Hai chose this, no one knows, anyway, one of the two model designs must be chosen.

The code name of this stealth fighter is still J-20, because this is a new generation of fighter.

After the fighter's appearance was determined, Liu Hai led the entire research project team to start the overall design.

The Spring Festival in 1996 was on February 18, so there was still a long time before the New Year.

Liu Hai was in these two project groups every day, and the research progress of the two project groups was very fast.

In terms of fighter design and manufacturing in China, Liu Hai had trained a lot of talents when he designed the Black Shark fighter.

The stealth fighter is mainly about its aerodynamic layout, its stealth material and its control system.

Liu Hai has solved the aerodynamic layout, and the research institute related to stealth materials has almost solved it. As for the control system, it is not very difficult. Now our country's semiconductor level is the first in the world.

The rest is the engine, and our engine technology in this time and space is also the world's leading.

In terms of materials, there are not only materials developed by Liu Hai himself, but also some materials with imported technology, including the engines of General Motors and Rolls-Royce introduced in the past, and some data of the Tu-160 engine were obtained from Lao Er.

In fact, as for the engine, the most critical thing is the material. As long as the material is sufficient, it is completely possible to make a very abnormal engine, just like the engine of Tu-160.

On New Year's Day in 1996, the junior sister found that Liu Hai got off work very early today, and after get off work, he sat in front of the TV to watch the news.

"What major news is announced today?" The junior sister saw her senior brother like this and knew that there was another important news on TV.

"There is major news, you can watch it later." Liu Hai nodded.

A few days ago, Liu Hai received a report from the rocket recycling project team, that is, the rocket recycling project has been initially successful, and the first satellite launch test has been carried out. The first stage of the rocket successfully returned from an altitude of 77 kilometers and landed at the designated location.

After preliminary judgment, the first stage of the rocket can be reused.

And according to previous data, the first stage engine of this rocket can be reused at least 35 times.

Soon the news came, and the first news at 7 o'clock was to report this matter.

"After the continuous efforts of our scientists, we have made great progress in the field of aviation!"

"Recently, an unprecedented test was carried out at a rocket launch base, a rocket recycling test."

Along with the words of the host, the picture of the rocket launch appeared on TV.

"The rocket recovery test means that the first stage of the rocket can be reused, thereby reducing the cost of space exploration and increasing the frequency of rocket launches."

"In this launch mission, the first stage of the rocket successfully separated from the second stage at an altitude of 77 kilometers, and the second stage successfully ignited and continued to perform the carrying mission."

"And the first stage of the rocket began to return from an altitude of 77 kilometers."

At this time, the picture in the TV was on the recyclable stage of the rocket, with one camera in the front and one in the back.

The camera in the front recorded the video of the second stage igniting and leaving.

And the first stage of the rocket began to return.

Of course, the video will not show the complete clip, because it still takes some time to return from 77 kilometers.

"The success of this rocket recovery mission has laid a solid foundation for our future space exploration."

"Before this rocket recovery mission, dozens of launch tests have been carried out, and behind them are the efforts of countless scientists and technicians."

At this time, the TV screen turned to the ground.

You can see that it is in a desert, and there is a flat area in the middle of the desert.

A little fire appeared in the blue sky.

That is the returning rocket. The returning rocket has to exert different thrusts at different altitudes.

And it not only involves the altitude, but also the weight of the rocket itself, because the biggest weight of the rocket itself is the fuel.

As the fuel is consumed, the weight of the rocket decreases, the altitude decreases, and the thrust also changes.

Another point is the fuel reserve of the rocket itself.

So there is a scene in the video, that is, the rocket begins to float in the air more than 200 meters away, and begins to move left and right.

The whole process lasted about 10 seconds.

These 10 seconds are actually to reduce the fuel of the rocket itself to below the safety line.

In addition, it also allows the rocket to adjust its position.

And it is this 10-second picture that shocked the world.

After 10 seconds, the rocket landed smoothly on the hardened ground in the middle of the Gobi Desert.

And the rocket was successfully shut down!

Of course, there is still a lot of work to be done later, which is not reported in the news.

After the rocket is recovered, there are still combustible gases and combustible fuels inside the rocket.

So it is also a very dangerous thing to extract these combustible gases and fuels. It is necessary to inject inert gas while extracting fuel.

"This looks very impressive!" The junior sister watched the huge first stage of the rocket hovering at an altitude of more than 200 meters, and then moving left and right. She didn't know how impressive it was, but she felt it was very impressive.

"Of course it's impressive, look at this!" Liu Hai took out a gold medal.

"Oh, you also participated in this project?" The junior sister was also very surprised to see the medal in the hands of the senior brother.

"To be clear, this project was initiated by me. Later, because this project only needed to be repeatedly tested, and it was more dangerous, I didn't care about it."

The junior sister looked at the back of the medal. Comrade Liu Hai made great and outstanding contributions to aerospace, and now Comrade Liu Hai is specially awarded the first prize!

"Oh." The junior sister was also very happy after seeing the words at the back.

Liu Hai also smiled, and there was also a certificate.

This project is indeed not easy. It took many years to succeed today with the development of semiconductors and communication technology.

When Liu Hai was laughing at home, many people in the international community were busy.

Ten minutes of news were recorded and analyzed frame by frame.

But since it is news, it must have been checked.

However, judging from the launch site, this is the Jiuquan Launch Site.

Rocket recyclable technology, this is actually mentioned by some people internationally.

The original intention of Bald Eagle to develop the space shuttle was to reduce the cost of space exploration.

Before the space shuttle, Bald Eagle predicted that the use fee of the space shuttle would be 30 to 40 million US dollars per time.

It was only later when the space shuttle was developed that it was discovered that the cost per time reached 400 to 500 million US dollars.

And in 2020, why did our country not develop rocket recyclable projects?

It is because we have to ensure that there is food to eat in the entire rocket development field.

Don’t look at the fact that Ma’s rocket recyclable technology is really awesome in 2020.

But many countries, including Bald Eagle itself, still choose the original way to launch.

On the one hand, it is space safety, and on the other hand, some things cannot be measured by money.

In 2020, the European Space Agency will also launch a new launch vehicle. Why do they want to launch a new launch vehicle instead of Ma’s? It is to ensure that they have someone with technology in this field.

If you rely on Ma, when you have no more people and no more technology, he will raise the price.

As long as the capitalists monopolize the market, the consequences will be extremely serious.

There are two reasons why China is showing this technology now. The first is to prove to the world that we have this technology.

The second is to grab business!

Grab the business of the bald eagle and the fat goose!

In the field of rockets, there are only 4 players in the world in this time and space.

Bald eagle, Europe, fat goose, and some countries in the East.

Historically, Fat Goose has made a lot of money using rocket technology, and there are so many rocket engines for exporting Bald Eagle alone.

Historically, most of the cargo and manned missions of the International Space Station were carried out by Fat Goose.

If the launch vehicle is just for our domestic service, then there is no need for recycling.

Because we need to maintain the upstream and downstream production and R\u0026D departments of domestic launch vehicles.

But to grab the market internationally, we need to have more cost-effective recyclable rockets!

Although it is impossible to grab all the international launch missions, because some things are not measured by money, such as from a security perspective, such as some satellites that are kept secret by various countries.

But commercial satellites can completely grab the business of these countries.

Again, the cake of commercial satellite launch missions on the entire earth is so big, if we eat more, others will definitely eat less.

When their income in this regard decreases, their R\u0026D investment will increase.

Indirectly consume the other party's funds.

The front page headline of the newspaper the next day also published this matter.

After Liu Hai bought a newspaper, it analyzed and evaluated the significance of rocket recycling!

And the experts above said that in the future, you may be able to experience a space trip for 100,000 yuan.

At the same time, Liu Hai also knew that the official quotation for commercial satellite transportation is 50% lower than the global level.

Because of the exchange rate issue, our rocket commercial satellite launch quotation is cheaper than that of foreign countries.

Now that the rocket recycling project has been successful, this 50% quotation is still profitable.

Regardless of whether there are orders or not, the price is published first.

After this price is published, it directly snatched the business of Fei Goose in this area.

As mentioned earlier, Fei Goose has strong technology in rocket launches and also has cost advantages.

Because there are only four companies in the world that can launch satellites.

Needless to say, the quotation of Bald Eagle is quite expensive.

The performance of European rockets is a little unsatisfactory.

Because Fei Goose has high rocket performance, strong technical strength, and their costs are relatively low, many commercial satellite companies are willing to choose Fei Goose.

Of course, our market share in this area is also very high, and many European countries come to us to launch satellites.

It's just that now we have lowered the price even further. It can be said that except for some orders that require protection fees, the three countries can't even think about accepting other commercial orders.

For orders that require protection fees, there is no way to do this. It's like a little notebook. Even though you know that the things sold to you by your bald eagle father are expensive, you still have to buy them because they are disguised protection fees!

However, the external quotation is an external quotation. These foreign satellite companies are still a little hesitant because this technology appeared too suddenly and it's too awesome!

It's so awesome that it doesn't seem like a product of this era, so everyone is a little skeptical about it.

The superior department has already had a countermeasure for this, which is to sell tickets.

In other words, as long as you buy a ticket, you can watch the rocket's reusable launch!

However, this policy has not been announced to the public because the superior department wants to build a rocket launch base in Hainan.

This base will mainly launch commercial rockets to the outside world in the future.

Some countries in the East have once again become the subject of media reports around the world.

Many experts have come out to question the authenticity of the reusable rockets of some countries in the East.

Because these experts have raised many questions.

There were no problems with the rocket during launch, separation at an altitude of 77 kilometers, and return.

However, the speed of the first stage of the rocket must be guaranteed on the way back.

The speed of this stage cannot be too fast.

Therefore, the control system is very demanding, because there is no way to intervene manually in this process.

Because manual intervention takes time, and the speed of rocket recovery is very fast, so everything depends on the rocket's own control system.

More countries expressed congratulations to some countries in the East!

Because for most countries, they do not have the ability to launch satellites, and some countries in the East have directly cut the cost of satellite launches in half, which is very beneficial to these countries.

By 2020, many countries in the world will not have their own satellites.

Even some countries' scheduled satellite orbits are directly occupied by others.

International satellite orbits, that is, whoever occupies it first will use it.

However, some countries in the East did not explain too much in this regard. Anyway, we have already quoted prices to the outside world. If you don't believe it, come and try it.

There are actually two reasons for the international doubts. The first is that some experts really doubt it, and the second is that some people are making trouble and want to use this method to make some countries in the East come up with more things to prove.

Rocket reusability technology actually uses 3G communication technology, and there are many ground auxiliary facilities.

It is used to help the rocket locate itself.

For example, the speed and height of the rocket itself can be measured not only by the rocket's own sensors, but also by ground equipment.

The Internet also had a heated discussion about this news.

However, Liu Hai just took a look, because most people don't know much about this kind of thing.

What foreign experts pointed out is correct, that is, the rocket recovery process completely relies on the rocket's own control system, and this control system was successful after dozens of repeated tests.

The success of rocket recovery also proves the development and application of our current science and technology from the side.

This is a product that can only be born when science and technology reach a certain level, just like Liu Hai launched this project in the early days, but the test progress was very slow at the beginning, because the rocket's own control system requires a lot of data and sensors.

These are related to semiconductors and control modules.

When semiconductor technology does not meet the standards, no matter how many experiments you do, it will not succeed.

And now semiconductor technology and communication technology meet the requirements, so it can succeed.

At the same time, Liu Hai also knew that the aircraft carrier purchased from Niu Niu is expected to start sea trials at the end of 1996.

First of all, the power system and the control part of the power system of this aircraft carrier are intact.

And other power systems, fire protection systems, radar systems, command systems, life systems, survival systems, three-defense systems.

Air defense systems, etc.

And these things have long been available in the 001 teaching building, and relevant experts have already thoroughly studied them.

So when this purchased aircraft carrier arrives at the shipyard, the relevant experts and technicians have to transplant the things in the No. 001 teaching building to the aircraft carrier.

What is lacking in the No. 001 teaching building is the power system, and the one purchased from Niuniu does not lack the power system.

And according to the plan of the superior department, it is expected that our nuclear-powered electromagnetic catapult aircraft carrier will be built next year.

Of course, this depends on the transformation of the first aircraft carrier. If the conditions are not up to standard, the second aircraft carrier will still be a conventional-powered aircraft carrier. As for whether it is a ski-jump takeoff or a catapult, we will see at that time.

Catapult takeoff has many advantages, and it has much more ammunition and fuel than ski-jump takeoff.

And catapult takeoff can also launch cargo planes, early warning aircraft, etc.

Liu Hai couldn't give relevant suggestions in this regard, because he had already put aside the aircraft carrier. What level of overall aircraft carrier design and construction in China has reached? It is difficult for him to evaluate.

So it was revealed on the Internet that some countries in the East built a ski-jump takeoff test bench on land somewhere.

This was taken by some countries with satellites.

Of course it is not the No. 001 teaching building. The appearance of the No. 001 teaching building is a school teaching building.

The ski-jump take-off test bench must be built, mainly for the training of carrier-based aircraft.

Liu Hai himself is also making rapid progress in the two projects on his side.

The entire fly-by-wire control system and electronic system of the White Swan are being designed and tested at the same time.

The only thing that is more complicated than a fighter jet is its variable swept wing.

However, this is just a small model in the data model.

What kind of flying posture and what angle its wings are at can be controlled by the onboard computer.

The White Swan is expected to conduct ground tests within half a year, and it is hard to say about flight tests.

At the end of January 1996, Sun Aiguo found Liu Hai with a thick bill: "Xiao Liu, this is the bill for 1995."

"Old factory director, please sit down quickly. You are so old and work hard every year. I feel bad. I believe you for the bill." Liu Hai said while pouring tea for the old factory director.

"We have a good relationship, so the bill should be paid. Besides, I am in good health now. I don't have any other problems. I don't suffer from insomnia anymore. I fall asleep right after running all day!" Although Sun Aiguo is over 70 years old now, he is still in good spirits.

"Since the old factory director said so, I will accept it. But your health should be the first priority. If you feel uncomfortable, come back!"

"Of course, but I need to find someone I trust to take over this."

"Of course I trust the old factory director!" Liu Hai also agreed with this, because these things can't be done in a short time, and it is foreseeable that his money will increase. To put it bluntly, at his current position, he won't spend a penny on himself, and there will be enough for his children and grandchildren.

"I saw the rocket recycling project succeed outside, and I felt that it was not easy. So many years have passed, and so many manpower and material resources have been invested!"

"At that time, it was thanks to the support of the old factory director, otherwise this project would not have been able to continue research for so many years."

"You are so modest!"

"After walking around the countryside, I found that the first thing is to build roads. Only after the roads are built can farmers sell their products. In fact, there are many good things in the mountainous areas, but they can't be sold."

"The old factory director sees the problem very clearly!"

"Time really flies. In a blink of an eye, you will retire too. We will have aircraft carriers and stealth fighters soon. It's worth it to see these things in this life!"

"Old factory director, you have such a good mentality and such a good body. It's no problem to live to 100 years old. By then, you will not only see our space station, but also see us plant the national flag on the moon!"

"Okay, I'll borrow your good words."
