Chapter 703 Targeted Research and Development (Second Update, 5000 Sub)

The predecessor of GPS is a meridian satellite positioning system developed by the Bald Eagle military in 1958. It was officially put into use in 1964. 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 1973 they began a demonstration experiment for a new generation of GPS.

Then it took 20 years and a cost of 20 billion US dollars to fully build in 1994 a new generation satellite navigation and positioning system with all-round real-time three-dimensional navigation and positioning functions on sea, land and air.

It has also been upgraded from 5 to 6 satellites in the first generation to 24 satellites. They are distributed in 6 orbits, and each satellite is about 17,000 kilometers from the ground.

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.

"Now 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 lost a lot at our original price."

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

"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."

"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."

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

"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."

"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."

"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."

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.

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.

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.

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

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

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

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

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

One day earlier it would be 100,000 US dollars, one year earlier it would be 36.5 million US dollars, which is also a huge amount.

As for spare parts, these are faster because the grounding has led to no orders from other airlines.

So now they are constantly selling their second-hand aircraft 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.

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

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

"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.

"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.

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.

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

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

"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 end his career, but he was afraid that some people would want to buy foreign planes.

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.

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

"Your idea is right. To put it bluntly, you have made so many contributions, but the people behind you may not necessarily appreciate your kindness unless you bring benefits to them." Sun Aiguo knows a saying, a new emperor chooses his own ministers.

I don't care whether I recognize the contributions of your predecessor or not.

This is also why Liu Hai doesn't like to make suggestions to the superior departments.

In history, there were several prime ministers who had a good ending, not because they relied on their own contributions to nag in front of the new emperor.

"The shares of the Institute of Traditional Chinese Medicine have been reorganized, and the relevant plans will be given to you later to see if you have any opinions."

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

"Hehe, this is because of the good leadership of my junior sister." Liu Hai smiled.

Of course, this pill sells well, because the distributor is the only authorized, of course, except for the only seller in our country.

The distributor directly finds local pharmaceutical companies with relatively large influence in each country for cooperation.

These pharmaceutical companies with relatively large influence in each country also have very close relations with the doctors in the relevant hospitals.

In addition, the distributors use different colors or shapes for the drugs sold in each country, and prohibit cross-selling in different regions.

A huge pharmaceutical interest group has been formed.

What about the aphrodisiac? Not to mention medicine, even if you say that a certain vegetable is good for this aspect, you can eat it to extinction.

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

"Haha!" Liu Hai laughed.

"Are you going to improve the anti-sea model of the flying motorcycle next?"

"Yes!" Liu Hai nodded.

Anti-ship missiles have long been available in my country, but they are similar to p15. This type 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 inertially guided, so it is conceivable that this thing can hit moving targets.

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

Although there are so many shortcomings, when Liu Hai traveled through time, Da Ge still took out these antiques to use.

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

In the 1980s, we got closer to Western countries, and then we obtained other anti-ship missiles, and then produced C602. Then after the 1990s, our anti-ship missiles began to explode and launched a variety of models.

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

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

Historically, these problems were not broken through until the late 1990s, but in this time and space, because Liu Hai solved the problem of high temperature resistant materials in the early years.

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

Even 3000 and 5000 are solid fuel propulsion.

Of course, the current 3000 and 5000 do not have the ability to maneuver at the end. In fact, it is also a large-sized mushroom-shaped monkey.

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

"I was just thinking about that. Your idea seems to be similar to anti-ship missiles. I don't know about this, but I seem to have heard relevant reports. I'll get you a detailed document later." Sun Aiguo directly agreed to find a document for Liu Hai.

Liu Hai nodded. The Gallic Exocet missile seemed to be equipped in 1979.

Then in 1982, it slapped the Niu Niu fleet hard in the Falkland Islands.

Then this model of Exocet sold out, and fortunately Argentina didn't have more Exocet at the time.

Otherwise, the Niu Niu fleet in history would be beaten up.

In history, after the Niu Niu fleet was attacked, the Gallic refused to deliver Exocet to Argentina.

Of course, the Exocet sold out later, and the price was of course not to mention. It seems that we introduced this model because we saw such a result in history.

Liu Hai prepared a sea strike, ultra-low-altitude flight strike distance of about 100 kilometers, mainly to give it to the local tyrants in the Middle East to put at home.

If the bald eagle wants to show off its power in this area, it will have to think twice.

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

Because his own is a custom-made model, it is mainly used in the Persian Gulf and the Red Sea.

As for why the small motorcycle is used, it is mainly so that once it is interfered with, it can automatically find a suitable target: hit the big one.

Of course, this kind of thing must be used with a simple launch and then forget, that is, this new type of targeted flying motorcycle, when the approximate distance of the opponent is known, it can be quickly debugged and then launched.

For example, if the target is 70 kilometers away, the active radar is designed to start when it is 5 kilometers or less away from the target.

That is, when the search is turned on at 65 kilometers, it will hit the largest one, without the need for fighter guidance or bomber guidance.

Many anti-ship missiles still rely on radar guidance, but they do not need guidance at the end.

Of course, this must be cheap, not as expensive as anti-ship missiles.

The main point is a large quantity, no matter how many anti-aircraft missiles you have on your warship.

Because of the cost-effectiveness, Liu Hai is not going to use a turbojet engine, but this can be used on our own models.

The turbojet engine is expensive, and the engine alone accounts for a large cost.

So Liu Hai is inclined to two ways, one is the internal combustion engine, that is, the slower the gasoline engine, the easier it is to turn and track the target.

The other is the high-speed version, that is, the solid rocket propulsion version.

As for the liquid rocket engine version originally considered, Liu Hai will also take it out, because liquid rockets are related to launch vehicles.

The best liquid rocket engine is still Fei Xiong. Before 2020, the launch vehicle of the Bald Eagle still uses Fei Xiong's rocket engine.

But now is not the time to dig into Fei Xiong's corner. Wait two more years, if Fei Xiong is no longer okay, Liu Hai will dig out the foothold.

The key technology of liquid rocket engines is the combustion chamber, and the fuel pump. The fuel pump and the combustion chamber are made of two completely opposite materials.

The fuel pump is ultra-low temperature and corrosion-resistant because of liquid fuel, while the combustion chamber is made of high temperature resistant material.

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

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

First of all, the rocket engine is not fixed at the bottom of the rocket, but is connected by something like a universal joint.

The direction of the rocket in the air is completely adjusted by 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 the liquid rocket fuel engine depends entirely on the delivery volume of its fuel pump.

The largest rocket thruster of the fat bear can deliver 1.5 tons of fuel per second. The fuel of the liquid rocket itself accounts for most of the weight and volume.

Of course, the amount of fuel delivered by the Saturn rocket engine of the bald eagle is even greater.

Liu Hai is also involved in these things, but he is not proficient in them. We will see how much he can do when the time comes.

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

Speaking of this, we have to talk about the third boss. In 2014, he launched a GS rocket with a total weight of more than 400 tons. Looking at such a large thrust, everyone thinks it is awesome, right? But its payload is only five tons, which is still low earth orbit. If it is geosynchronous orbit, it is only 2.5 tons. The parameters of the launch vehicle in 1997 in our country's history are stronger than this.

So suddenly I heard some countries promote 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, the third boss was said to have made a rocket with a total weight of more than 600 tons, so its engine thrust is at least 800 tons. As for its specific carrying capacity, it has not been announced. Anyway, the third boss has one meaning: heavy is good, heavy is expensive.

Just like what Liu Hai learned, when buying a mobile phone in many places, people will put a scale there. These people will put the mobile phone on the scale when buying a mobile phone. The heavier one is good and expensive, and the lighter one is not good.

Of course, the third boss is much better than the small notebook and the small stick. At least others sent 5 tons. Let’s not talk about these two.

Of course, the third boss also has a historical record, that is, it launched 104 satellites at a time, directly surpassing a certain big country in the East and stepping on the big goose in the north.

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

"Thank you, Director." Liu Hai naturally had his own plan in mind, mainly to deal with the Bald Eagle going to that area to pick up leaks in the late 1980s.

In the mid-to-late 1980s, the fat bear saw that it was not going to work, so the Bald Eagle circled the world, sending an aircraft carrier fleet here to deter, and then sending an aircraft carrier fleet to other conflicting areas, shouting slogans passing by to make trouble.

This situation must be curbed, so how to curb it? Of course, one hand is the economy and the other hand is the big stick.

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

"It's the individual air defense missile. This can't be sold, otherwise Fatty Bear might be desperate." Sun Aiguo's words scared Liu Hai.

"No, leader, wait a few more years, Fatty Bear won't leave that place for a while. If we take out the individual air defense missile now, it will be difficult for us to sell helicopters." Liu Hai is still waiting for Fatty Bear to teach the European nobles a lesson next year, and then we will sell helicopters in a big way.

After selling helicopters for a few years, it feels that helicopters are not selling well. When the market is saturated, we will sell this kind of individual air defense missile.

On the one hand, Fatty Bear is too strong now, and it is not appropriate to go against him. On the other hand, it is to maximize their own interests.

Try to sell him thousands of helicopters before the Cold War eases, so that this market will not have a market until decades later.

Because there has been no large-scale conflict since the Cold War until Liu Hai traveled through time, these helicopters naturally have not been consumed much, and at most they are repaired and upgraded.

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

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

"Okay, I will help you find information now. You have worked hard and 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 turned back to look at the information sent by the factory director.

The dealer requires the next generation of super yachts to be at least 80 or 100 meters long, as luxurious as possible, and design fees are not a problem.

"Do you want to equip the dealer's yacht with an air defense system?"

"Large air defense missiles cannot be equipped, and individual air defense missiles can be directly changed."

"Otherwise, turn this individual air defense missile into a small vertical launch!"

"Forget it, there are too many things related to this vertical launch system."

"Wait another two years for the vertical launch system!"

"Let's go and see the construction progress of the aircraft carrier teaching building first, it's almost September."
