Chapter 701 The First Jetliner (Second update. 5000 words)

The prototype of this aircraft is the 550 model business jet launched by Gulfstream in 2003, which is known as the most successful business jet.

It is also a medium and long-distance business jet that can fly directly from Kyoto to Los Angeles, Australia or Europe, with a range of more than 11,000 kilometers.

It can accommodate 16 people, with a maximum of 18 people, and has three temperature zones. It also uses a unique air pressure system.

It can ensure the pressure in the cabin at an altitude of 1,800 meters, while other aircraft can only maintain an air pressure at an altitude of about 2,400 meters.

This is why some people feel uncomfortable flying because of the pressure in the cabin.

Therefore, this business jet is particularly comfortable for people to sit on.

Of course, people who are not sensitive to air pressure will not feel it, just like some people who go to high-altitude places are fine, but some people feel uncomfortable when they reach an altitude of 2,000 meters or 3,000 meters.

However, this kind of confined space is relatively sensitive to air pressure.

The maximum ceiling altitude can reach 15,000 meters, and the flight speed can reach more than 1,000 kilometers per hour.

Of course, this aircraft also adheres to Gulfstream's consistent design, which is to look good.

Of course, the various systems on the private jet manufactured by Liu Hai at this time were not as powerful as the original model, such as the visual enhancement system, assisted driving system, etc.

However, the modified space bangs have been left. I believe this aircraft can be modified for decades.

Although we are talking about private business jets, the final assembly process is still very cumbersome.

This is because we need to inspect and test during final assembly, and we also need to formulate production processes at the same time.

Even before the entire aircraft comes out, there are already a lot of orders.

Moreover, this aircraft has also launched special services, that is, exclusive customization services. The owner of the aircraft can design the layout of the cabin independently.

That is, where is the reception room, where is the lounge, and where is the bathroom.

You just want to install a big bed, no problem.

The cabin width is 2.24 meters, the length is 29.4 meters, and the usable area is close to 50 square meters.

At the end of the month, Ni Nan officially submitted a plan to replace optical cables for railway network communication construction. Liu Hai spent nearly 200 million US dollars to purchase advanced foreign optical fiber production technology patents.

The main reason is that these technology patents involve many basic patents, and the application scope of optical fiber is not very wide now, so the price of bangs is still relatively cheap.

Of course, it is not just the technology patents for the optical fiber itself, but also the technology patents for signal transmission and other equipment solutions, because if you want to develop related solutions yourself, you may have to wait for several years.

If you don't carry out large-scale civilian production, you don't need to buy these technology licenses at all. You can just install one for testing purposes, and no one will charge you royalties.

Of course, Liu Hai can be a little more rogue, that is, the gap between domestic patents and foreign patents is just like the piracy of our country's operating system later.

Bangs are just for future development, and to give other people a good impression, otherwise others will say that someone started his career by stealing other people's technology. (Don’t overthink it!)

Once such a reputation is attached to your head, you will never be able to clean it off for the rest of your life, no matter how successful you become in the future, or how you clear your name.

No matter how much money you make, others will just sigh.

However, in this way, the overall investment will increase by at least 50%, but there is also an advantage, that is, the subsequent maintenance and management costs will be reduced, because the power consumption of optical fiber will be lower than that of cable.

Because cables require current to carry signals, optical cables use light to carry signals.

However, due to the replacement of optical cables, a lot of laboratories were added, including wavelength division multiplexing technology.

This technology used only two wavelengths in the early 1970s: one wavelength for the 1310 nm window and one wavelength for the 1550 nm window, using WDM technology to achieve single-fiber dual-window transmission.

The fastest growth of wavelength division technology was in the early 1990s, because at that time optical fiber networks began to be used on a large scale.

The railway department has no objection to this change, except that construction technicians need to be retrained.

This is not a problem for the railway department. The railway department has this advantage. It is a separate and independent department, and all departments are included in it.

As long as there is an order from above, no one dares to obey or disobey it, and there is no need to coordinate with other departments for land, electricity, and other things.

As long as the plan is made to build a substation in this place, it can be built very quickly.

Moreover, the railway department also has the advantage of building this network, and subsequent maintenance is also convenient.

Railways already have line patrolmen, and once something goes wrong on the railway, it can be quickly repaired. After all, it is right next to the railway.

And with the economic development of our country, more and more railways will be built.

Moreover, various places respect the railways. If you offend the railway somewhere, believe it or not, the specialties of your place will not be shipped out.

The railway department is still doing preliminary preparation work, training personnel and exploration planning.

There is not much difference between optical cables and electrical cables in civil construction work. Of course, civil construction can only begin after the planning is completed.

However, if construction is to start, it is expected to be in the second half of next year, because the optical cable has not yet started mass production.

The manufacturing of optical cables was also directly authorized by Fenghuo Company to relevant domestic manufacturers, and then these manufacturers produced optical cables to offset the accounts. Liu Hai did not share dividends with the manufacturers.

Of course, Liu Hai authorized two manufacturers, and the one with better quality was used.

Not authorizing a single factory alone would be detrimental to the future development of technology.

If another factory failed to meet the quality requirements several times in a row, the authorization would be withdrawn and given to other manufacturers.

Liu Hai also had no time to send people to these factories to keep an eye on them.

In September 1980, a major event occurred internationally, that is, the conflict between the Kingdom of Babylon and Persia.

On the first day of the conflict, the Kingdom of Babylon directly sent 50,000 flying motorcycles to Persia, severely damaging more than 400 military targets in Persia.

However, Persia was not to be outdone. After the King of Babylon launched 50,000 flying motorcycles, the Kingdom of Persia directly sent more than 70,000 flying motorcycles to the Kingdom of Babylon.

As a result, all the airports in the Kingdom of Babylon were destroyed, as well as many important facilities.

However, in terms of military strength, the Kingdom of Babylon had a considerable advantage and directly advanced into Persia.

The strange thing is that the air forces of both countries could not be deployed, and the ground forces fought back and forth.

It's not that the air forces did not want to be deployed, but the airports were destroyed and were under repair.

Then the two sides launched flying motorcycles directly at each other's airports every day.

Although the two countries have a lot of air defense forces, they can't stop the massive flying motorcycles.

They can't stop them at all. No matter how dense the anti-aircraft guns of these air defense forces are, and how many anti-aircraft machine guns there are.

They can be broken through the air defense line by flying motorcycles.

As for anti-aircraft missiles, the two countries fought a wave at the beginning, but then they let it go.

Even if an anti-aircraft missile intercepts an air motorcycle, how can so many flying motorcycles intercept it?

Although the flying motorcycles are loud, the casualties they cause are not very large.

It turns out that the flying motorcycles make sounds. As long as the people on the ground hear the sound, they will run away quickly.

As long as the flying motorcycles don't explode directly around you, there is basically no danger.

After all, the speed of the flying scooter is relatively low, and the internal combustion engine has no muffler, so the humming sound can be heard from a long distance. Besides, both sides have made arrangements in this regard and added many observation posts.

The best way to deal with the flying scooter now is to increase the number of observation posts. Once you hear a sound in the air, call and report immediately.

Although people and equipment can enter the bunker, there is no way to deal with the airport radar antenna.

Persia and the Babylonian Kingdom exchange flying scooters every day to ensure that the other party's air force cannot fly into the sky. On the other hand, they have increased the maintenance of their own airports.

However, the Babylonian Kingdom only entered the Persian territory in the first wave, and it was not possible afterwards.

Because no matter how many tanks there are, they can't defend against tandem RPG rockets, and the fight has become a positional war.

Of course, with the conflict between the two sides, international oil prices have risen.

Liu Hai looked at the private plane in front of him. After more than a month of intense work, the first small jet airliner was assembled.

However, the completion of the assembly is just the beginning. A series of tests, ground tests, fly-by-wire flight control tests, etc. will be carried out later.

Two experienced pilots started the plane according to the operating manual, and the plane began to taxi on the runway.

The two sides communicated with each other by radio while taxiing, and various tests were also carried out during the taxiing, such as control system tests.

Then observe the personnel and carefully observe the reactions of the tail wing, etc.

It is not known how long the ground test will take, anyway, the flight test can only be started after the test is completed.

Liu Hai estimated that this process would probably take at least three or four months, and it is hard to say the longest.

Because everyone had no experience in the fly-by-wire system at the beginning, this can only be obtained through continuous testing and finally optimized.

However, Liu Hai has already built this framework. As for whether other departments can learn it later, it depends on others.

In history, our country's fly-by-wire began with the bald eagle helping us upgrade our fighter jets. Of course, it was at that time that the bald eagle completely looked down on the fighter jets we produced.

Because the screws on the two J-8s were not universal, the aircraft engineers of the bald eagle could not understand how such an aircraft could fly into the sky.

At that time, there was no industrial standardization at all, and repairmen had to handle parts by themselves. If you said the screws were small, you could just wrap some hemp rope around them.

If you say the screw is too big, just get a tool and make the hole bigger.

If that doesn't work, use rivets.

If that doesn't work, use electric welding.

If that doesn't work, just use wire to tie it up.

No matter what method you use, just fight it.

But later, due to changes in international relations, the two aircraft that had not been upgraded were sent back.

Then we learned that Bald Eagle was working on the fly-by-wire system on the fighter.

Several leaders and factory leaders watched the plane taxiing for a circle, and applauded after returning.

The ground taxiing test of the aircraft can be said to have achieved preliminary success.

"It seems that our country's jet passenger aircraft should be not far away!" The leaders of the superior department looked at the jet aircraft. Although it has not been painted yet, its elegant appearance makes people like it at first sight.

"That's for sure!" Sun Aiguo answered as a matter of course.

"Let's wait until Heshun Aircraft Manufacturing Company smoothes things over!" Liu Hai feels that it will be difficult to design and manufacture our own aircraft within at least five years.

Because within these five years, the main purpose is to cultivate aircraft manufacturing talents and absorb advanced foreign aircraft manufacturing and design technologies.

It is already very good to be able to fully understand foreign advanced technologies in 5 years.

Of course, it is possible that the time point will be advanced, because the technical staff of Rolls-Royce and McDonnell Douglas are like chicken blood. Not only do they have to work overtime, but they also have to ask questions if they don’t understand.

Of course, this is also the charm of money.

Then everyone took a group photo in front of the plane.

"It's so beautiful!" Liu Hai took the photo back to his junior sister to admire. The junior sister was pregnant with her second child again. Looking at the smooth lines of the plane in the photo, the junior sister liked it at first sight.

The junior sister is also happy for her senior brother from the bottom of her heart.

"I will give you one when the time comes. You can see for yourself how you like to decorate it." Liu Hai smiled and hugged his junior sister and said.

"You should do the design, I don't understand these things?" When the junior sister heard this, her heart was moved, but she knew her design ability.

"I will have a lot of samples here by then. I will show them to you first. Just give me your suggestions and I will design them." Liu Hai replied with a smile.

"You've been working too hard these days." Junior sister knew that Liu Hai was busy with the plane recently.

"I'm not working very hard, I just use my mouth." Liu Hai replied with a smile.

The first aircraft undergoes final assembly during the day, and takes time to conduct summary meetings at night.

It means that everyone should talk about the problems encountered during the day at night, and then everyone involved should understand how the problem occurred, how to solve it, and why it should be solved in this way?

In fact, Liu Hai is very lucky that standardized production has become deeply rooted in the hearts of the people.

Liu Hai still remembers the two years when he started producing motorcycles. Some old workers could not correct the problem. For example, if there was a quality problem with a part, the old workers would just make it for you if they saw it was usable. They didn’t care about your quality standards at all. standard.

Fortunately, the superior leaders came to write the inscription at that time, and these people in the factory no longer dared to follow their own ideas.

Now when it comes to production issues, no one comes out to talk high-key.

"Yeah!" When the junior sister heard Liu Hai say this, of course she nodded in agreement.

After the junior sister became pregnant with her second child, the junior wife came to live with Liu Hai again and hired three nannies, some of whom were responsible for cleaning and some who were responsible for taking care of the children.

The teacher also bought several old houses, knocked them down and started building new ones.

Liu Hai also bought several courtyard houses in Houhai. Nowadays, courtyard houses are really cheap. They can be purchased for a few thousand yuan at most.

These courtyards were torn down and rebuilt, repairing old ones with old ones, re-laying various pipes and underground pipe networks.

The whole family of those who sold these courtyard houses went abroad. These people are considered very rich in the eyes of ordinary people nowadays, because they sell houses and various old items, which can be sold for tens of thousands of yuan in total.

They took out a few from these courtyards and asked Wang Hongmei to hand them over to her cousin. Although no one else took the initiative to ask for them, the bangs are not bad now. After all, after sleeping under the same quilt for more than ten years, you have to show some conscience.

Although domestic wages have increased now, for most people, a household worth 10,000 yuan is still a legend.

However, the number of domestic workers now is many times that of the same period in history, and the value of industrial output is many times that of history.

The main reason is that our country spends too much money on railways, roads, ports and other aspects.

"How much does this plane cost?" Junior Sister asked another question.

"The price has not been discussed yet, but it should be between 20 and 30 million US dollars. Of course, it depends on the decoration inside. If more gems or more luxury goods are used, it may be 50 million or 60 million." Liu Hai He spoke.

"It's so expensive. Our laboratory can't even use 50 million US dollars a year, with so many people and so much equipment." When the junior sister heard this, she was extremely surprised.

"These are originally prepared by rich people. If the price is lower, they still won't buy them."

"I estimate that the most expensive one might cost hundreds of millions of dollars." Liu Hai thought of the Emperor.

The emperor of this time and space is extremely rich. Just the female hygiene products company and the facial mask company make a lot of money every year.

This benefit does not belong to the royal family, but to the King personally.

In addition, the Emperor likes natural royal blue, which is lapis lazuli. This thing is sold by Lunke, and there are many colors in it. The most expensive one is called emperor blue.

How much does an aircraft cost? In addition, there are also luxury goods inside, such as carbon fiber or Yun brocade and Shu brocade.

This is just like decorating a house. It can cost 100,000 yuan for simple decoration, or it can cost several million for luxurious decoration.

Even when it comes to building a house in a rural area, some people can repair the house with one or two hundred thousand, and some even spend tens of millions or hundreds of millions.

Not to mention that kind of Chinese-style house with all imported solid wood. Anyway, Liu has heard in his life that there is a Chinese-style villa in Suzhou. It is said that just the decoration is just short of 10 small goals. It is decorated in a Chinese style, with all the pavilions and pavilions. Made using ancient methods.

"It's so expensive, why not forget it?" Junior Sister shook her head when she heard so much money.

"Of course the things we produce ourselves don't cost that much money." Liu Hai replied with a smile.

"But where does this plane stop?" The junior sister just said she didn't want it, but actually she still wanted it, so she asked again.

"Put it in the airport in our factory. When the time comes, we will build a hangar to house our planes. Then I will teach you how to fly the plane." Liu Hai hugged his junior sister and said.

"Is it difficult to fly a plane?" the junior sister asked, her eyes brightening when she heard that she could learn to fly a plane.

"It's not difficult." Liu Hai can fly a plane himself, so he thinks it's not difficult to fly a plane.

In fact, flying a plane is very difficult in many cases. Many pilots have to hold a piece of paper to carefully compare the procedures before taking off.

Of course, these require strict training and absolutely no mistakes are allowed.
