Chapter 703 Targeted Research and Development (Second update, 5000 pieces)
The predecessor of GPS is a meridian satellite positioning system developed by the Bald Eagle military in 58. It was officially put into use in 64. This system consists of 5 to 6 satellites, which can circle the earth up to 13 times a day, and cannot give altitude information. , so the accuracy is very impressive.

However, this system was not very good at all, but it provided the bald eagle with a wealth of experience, so in 73 they began a demonstration experiment for a new generation of GPS.

Then it took 20 years and a cost of 200 billion US dollars to fully build in 94 a new generation satellite navigation and positioning system with all-round real-time three-dimensional navigation and positioning functions on sea, land and air.

也从第1代的5~6颗卫星升级到24颗卫星，它们分布在6个轨道上，每颗卫星距地面约1.7万公里。

And it’s only 1980, so it’s not too late if we catch up now.

So the current commitment of the Bald Eagle is largely a pie-in-the-sky behavior.

Of course, historically we have not been able to invest in such large research.

But things are different now. We have the strength and of course we have to be independent.

"Boss, you are really good at judging people!" Liu Hai flattered me with a smile.

"Hehe, our ancestors said it well, if you show courtesy for nothing, you will be raped or stolen. How can they give us free things when they spend so much money?" Sun Aiguo laughed.

As for parts, because other airlines do not want to place orders, aircraft parts can also be sent to China in advance.

"Heshun Aviation Flight Machinery Manufacturing Company should have all the runways completed by the end of this year, and all factory equipment will be in place in the first half of next year, and trial production will begin."

This is why Liu Hai doesn't like to make suggestions or suggestions from superior departments.

Therefore, Liu Hai will set up a civil aviation company, but there is no specific operation. If anyone reaches out, don't blame yourself for the consequences.

"You have a good idea!" Sun Aiguo, an old fox, heard what Liu Hai said and understood what was going on.

Liu Hai knew that the first batch of aircraft that Sun Aiguo said in the second half of next year would be all parts imported from McDonnell Douglas.

"Your junior sister is really amazing. Three pharmaceutical factories have to produce at full capacity to meet export needs. I'm afraid the patent fees will cost hundreds of millions of dollars this year."

These pharmaceutical companies with relatively large influence in various countries also have very close relationships with relevant hospital doctors.

"We'll see later." Liu Hai didn't care about this. The reason why he said that to Sun Aiguo in the first place was mainly to pave the way for the future.

McDonnell Douglas is also very fortunate to have signed aircraft sales contracts with certain Eastern countries. Otherwise, it would be in a mess now.

Then the other half of the parts will be produced locally, which means that the two lines will be started at the same time until the skilled workers in the final assembly line can master the final assembly process.

"It is expected that the first batch of assembled aircraft will be rolled off the assembly line in the second half of next year. By then, we will have no shortage of large civil aviation aircraft in China."

"You can open an airline, but I won't make commercial passenger planes for the time being. If someone doesn't buy my plane, I will make it." Liu Hai didn't plan to give up, but he was afraid that some people would want to buy foreign planes.

After all, airlines can't stand this kind of accidents and groundings every three days.

In history, several chief ministers and assistant ministers ended up well, either because they relied on their own merits to embarrass themselves in front of the new emperor.

"Do you want to be the airline yourself then?" Sun Aiguo asked again after hearing Liu Hai's answer.

As for parts and components, these are faster because the grounding has led to the cancellation of orders from other airlines.

Therefore, he had more free personnel, so he sent many people to Heshun Aviation Company.

"The shares of the Institute of Traditional Chinese Medicine have been reorganized. We will give you the relevant plans later to see what you have to say."

Liu Hai nodded when he heard what the factory director said: "So if the bald eagle wants to give it to us for free, it must be holding back."

"Your idea is right. To put it bluntly, after you have made so many contributions, the people behind you may not appreciate your favor unless you bring benefits to him." Sun Aiguo knows a saying. The emperor and his courtiers.

"Now that we are able to do this, the money we make from Feitian Motorcycle is enough. Thanks to the dealer who raised the price in the first place. Otherwise, we would have suffered a huge loss at our original price."

"If you don't have enough funds here, you can ask the superior department to advance payment for you. Anyway, your overseas income will continue to grow every year."

The new civil aviation aircraft developed by McDonnell Douglas is even more attractive. There were originally orders from airlines before the development, but after testing, many problems arose, and airlines did not dare to place orders.

"But the dealers themselves also make a lot of money. Not only do they make a fortune selling Feitian Motorcycles, they also make another fortune from the materials they sell to us, and they also support their huge fleet."

So now they are selling the second-hand aircraft they have at reduced prices. When the time is right, Liu Hai will buy a batch of second-hand aircraft, even if they are used for cargo transportation.

Each workshop that produces parts here can also produce parts independently.

"Hehe, this is junior sister's good leadership." Liu Hai chuckled.

Distributors directly seek cooperation with local pharmaceutical companies with relatively large influence in each country.

"It's also mutually beneficial. They have ordered a lot of cargo ships from us in the past few years, of various models. This has indirectly put the small and small shipbuilding industry into recession."

Sun Aiguo nodded: "That's right."

One day earlier it would have been US$10, and one year earlier it would have been US$3650 million. This is also a large amount of money.

According to the current progress, it may be at least a year earlier than agreed in the contract.

McDonnell Douglas' planes were grounded due to the air crash, and now Liu Hai's one is his only order.

Half of the purchased aircraft are delivered as parts to the final assembly workshop of Heshun Aircraft Manufacturing Company, where workers are trained for final assembly.

"People's hearts are separated from each other. There are some things that we have to guard against." Liu Hai also shook his head.

"It's a pity that these guys don't believe in our aircraft design level. They politely refused what we said last time." Sun Aiguo sighed.

Greatly accelerated the personnel training and equipment installation of Heshun Aircraft Company.

Of course, this pill is selling well because the dealer is the only authorized one, except of course the only seller in our country.

It doesn’t matter whether I recognize you as the hero of your previous term or not.

"The money you invested will finally see a return. To be honest, I'm afraid the financial pressure on you is still a bit high, especially the new network solution."

In addition, dealers use different colors or shapes for the medicines sold in each country, and cross-selling in different regions is prohibited.

A huge pharmaceutical interest group has formed.

What do you mean by aphrodisiacs? Not to mention medicine, if you say which vegetable is good for you, you can eat it until it becomes extinct.

"Your family are all geniuses. I think they are all influenced by you." Sun Aiguo chuckled.

"Haha!" Liu Hai chuckled.

"Are you going to perfect the sea model of Feitian Motorcycle next?"

"Yeah!" Liu Hai nodded.

Our country has already had anti-ship missiles, but they are similar to the P15, which uses liquid fuel rocket engines and has a range of only more than 30 kilometers.

This thing has a lot of shortcomings. First of all, it can only be guided by inertia, so it can be imagined that this thing will hit moving targets.

In addition, the biggest shortcoming of liquid fuel rocket engines is that the fuel is toxic, and its infrared and radar characteristics are very obvious.

Although it has so many shortcomings, Dae still used these antiques when Liu Hai traveled through time.

The main reason is that Da Goose's family background is too rich.

Historically, in the 80s, our relationship with Western countries became closer, and we obtained other anti-ship missiles, and then produced the c602. Then after the 90s, our anti-ship missiles began to explode, and various models were launched.

Later, our anti-ship missiles took two routes, one was a solid fuel engine and the other was a turbojet engine.

At this time in history, our solid fuel rocket engines had many shortcomings. The first was the formula, and the other was high-temperature resistant materials.

Historically, these problems were broken through in the late 90s, but in this time and space, bangs solved the problem of high-temperature resistant materials in the early years.

So we are much better than in history in terms of solid fuel rocket engines.

Even if it costs you 3000 lives, or if it costs you 5000 lives, it is all solid fuel propulsion. Of course, the current one costs you 3000 lives and 5000 lives. It has no terminal maneuverability. It is actually a large flying monkey with mushrooms.

So Liu Hai asked: "Do we have anti-ship missiles now? How is their development going?"

"I was just about to say that your idea seems to be somewhat similar to anti-ship missiles. I don't know about this aspect, but I seem to have heard relevant reports. I will get you a detailed information later." Sun Aiguo directly promised Liu Hai Find a piece of information.

Liu Hai nodded. The Gallic Flying Fish missile seemed to have been equipped in 79.

Then in 82, he gave Niu Niu's fleet a hard slap in the face on Falklands.

Then this model of Flying Fish sold out. Fortunately, Argentina didn’t have any more Flying Fish on hand at the time.

Otherwise, the Niu Niu Fleet in history would have been beaten to a pulp.

Historically, after the Niu Niu fleet was attacked, Gallic Chicken refused to deliver flying fish to Argentina.

Of course, Feiyu soon sold out, not to mention the price. It seems that we also introduced this model after seeing such results in history.

Liu Hai is preparing a kind of attack on the sea, an ultra-low-altitude flight attack distance of about 100 kilometers, mainly to give it to the wealthy people in the Middle East to keep at home.

At that time, the bald eagle will have to reconsider if it wants to show off its power in this area.

Liu Hai believes that even if there are anti-ship missiles now, they are definitely not as good as the ones he made himself.

Because this is a customized model, it works well mainly in the Persian Gulf and Red Sea areas.

As for why the small motorcycle is used, the main reason is that once it is disturbed, it can automatically find a suitable target: hit the big one.

Of course, this kind of thing needs to be simply launched and then ignored. This is a new type of targeted flying motorcycle. Once you know the approximate distance of the opponent, you can quickly debug it and then launch it.

For example, if the target is 5 kilometers away, the active radar is designed to be turned on when it is kilometers or less from the target.

That is to say, when you start the search at 65 kilometers, you will hit the largest one, without any guidance from fighter jets or bombers.

Many anti-ship missiles rely on radar guidance, but no guidance is needed at the end.

Of course, this also needs to be cheap, not as expensive as anti-ship missiles.

The main thing is to have a large quantity and a full control, regardless of how many anti-aircraft missiles you have on the warship.

Due to cost-effectiveness reasons, Liu Hai is not planning to install a turbojet engine, but this can be used in our own models.

The cost of a turbojet engine is high, and this engine alone accounts for a lot of cost.

Therefore, Liu Hai still prefers two methods. One is driven by an internal combustion engine, that is, the slower the gasoline engine, the slower the speed. The slower the speed, the easier it will be to turn and track the target.

The other is the high-speed version, which is the solid rocket thruster version.

As for the liquid rocket engine version originally considered, this Liu Hai also needs to be taken out, because the liquid rocket is related to the launch vehicle.

The best liquid rocket engine is Fat Bear. Before 2020, the Bald Eagle launch vehicle still used Fat Bear's rocket engine.

But now is not the time to poach Fat Bear. If Fat Bear fails in another two years, Liu Hai will have to poach him.

The key technologies of liquid rocket engines are the combustion chamber and the fuel pump. The fuel pump and the combustion chamber are completely opposite materials.

Because the fuel pump is liquid fuel, it is made of ultra-low temperature, corrosion-resistant materials, while the combustion chamber is made of high-temperature resistant materials.

Because the fuel of liquid rocket has ultra-low temperature, strong oxidation and high corrosion.

There are too many things involved. Even in 2020, Max is using a liquid rocket engine. In fact, his kind of rocket engines that propel together have been tested in this era and have many shortcomings.

First of all, the rocket engine is not fixed to the bottom of the rocket, but is linked by something similar to a universal joint.

The rocket adjusts its direction in the air entirely by relying on the rocket nozzle below.

The biggest problem with dozens of liquid rocket engines in parallel is resonance. Another point is fuel distribution. The thrust of a liquid rocket fuel engine depends entirely on the delivery volume of its fuel pump.

Fat Bear's largest rocket thruster can transport 1.5 tons of fuel per second. The liquid rocket itself takes up most of the weight and volume.

Of course, the Bald Eagle's Saturn rocket engine delivers a greater amount of fuel.

Bangs are also involved in these things, but I can’t say I’m proficient in it. We’ll see how much we can do later.

Of course, the launch vehicle is not just an engine problem, the overall design and overall control are also very important.

At this point, we have to talk about the third leader, who launched a GS rocket with a total weight of more than 14 tons in 400. Looking at such a large thrust, everyone thinks it is very awesome, right? However, its payload is only five tons, which is still in low earth orbit. If it is in geosynchronous orbit, it is only 2.5 tons. In the history of our country, the parameters of the launch vehicle in 1997 were stronger than this.

So I suddenly heard some countries’ propaganda that their rockets have reached 500 tons of thrust, 600 tons of thrust, and 800 tons of thrust. It’s useless!

When Liu Hai traveled through time, it was said that the third master built a rocket with a total weight of more than 600 tons, so its engine thrust was at least 800 tons. As for its specific carrying capacity, it has not been announced. Anyway, the third master means one thing: heavy means good. Heavy means expensive.

Just like what Liu Hai learned, when buying mobile phones in many places, others will put a scale there. These people will put a mobile phone on the scale when buying a mobile phone. If it is heavy, it will be expensive. If you are light, it will not be good.

Of course, the third master is much better than a small book and a small stick. At least others sent 5 tons, let alone these two families.

Of course, the third leader also has a historical record, that is, he launched 104 satellites at once, directly catching up with a large country in the East and stepping on the big goose in the north.

As for the total weight, it reaches a full 1.38 tons.

"Then thank you, director." Liu Hai naturally had his own plan in mind, mainly in case the bald eagle went to pick up leaks in that area in the late 80s.

In the mid-to-late 80s, the Fat Bears were about to die, so the Bald Eagles were all over the world. They sent an aircraft carrier fleet here to intimidate them, and then sent an aircraft carrier fleet to other areas with conflicts, shouting slogans as they passed by to stir up trouble.

This situation must be curbed, so how to curb it, of course, is to use the economy in one hand and a big stick in the other.

"This is what I should do. You have a keen insight in military aspects, of course not only in military aspects, but also in other aspects." Sun Aiguo waved his hand.

"It's just a man-made anti-aircraft missile. There's no way to sell this, otherwise Fat Bear might jump over the wall." Sun Aiguo's words startled Liu Hai.

"No, leader, wait a few years. Fat Bear won't leave that area for a while. If we take out the individual air defense missiles now, it will be difficult for us to sell helicopters." Liu Hai is still waiting for Fat Bear next year. Give lessons to those nobles in Europe, and then we will sell helicopters like crazy.

After selling helicopters for several years, I feel that helicopters can no longer be sold. When the market is saturated, I will sell this type of individual air defense missile.

On the one hand, this is because Fat Bear is too strong now and it is not appropriate to go against him. On the other hand, it is to maximize his own interests.

Try to sell thousands of helicopters before the Cold War eases, so that there will be no market for decades.

Since there has been no large-scale conflict since the Cold War until Liu Hai crossed over, these helicopters naturally did not consume much, and at most they were repaired and upgraded.

And if you really sell thousands of helicopters, you can make a lot of money from after-sales maintenance.

"Hehe! We have also considered this." Sun Aiguo smiled slyly.

"Okay, I'm going to help you find information now. You've worked hard too. There are so many things to do." Sun Aiguo patted the information on the table and said.

"Okay." Liu Hai sent the factory director away, and then looked back at the information sent by the factory director.

Dealers require the next generation of superyachts to be at least 80 or 100 meters in length and as luxurious as they want. Design fees are not a problem.

"Should we install an air defense system on the dealer's yacht?"

"Large-scale air defense missiles cannot be equipped, and they can be directly converted into individual air defense missiles."

"Otherwise, we can turn this individual anti-aircraft missile into a small vertical hair!"

"Forget it, this hanging hair system involves too many things."

“Let’s wait another two years for the hanging hair system!”

"Let's go take a look at the construction progress of the aircraft carrier teaching building first. It's already September now."
