Chapter 388 Shameless (first update)
There were no tasks assigned to the Maintenance Department a year ago. This year, the factory has heavy production tasks, so there will be no holidays. We will work as normal, and of course there will be no benefits.

The motorcycle factory produces items that are in short supply, from airplanes to yachts to sports cars, and now Pioneer... no, Rover cars.

Because these are high-end products, employees must have rest. Moreover, there are not so many modern automated equipments, and manual labor is very demanding, so they work overtime in turns.

Liu Hai was also glad that he was not a leader. When he was a leader, he had to set an example. There were still three days of Chinese New Year, so Liu Hai just let go of the sheep and asked for a leave from the factory director.

In the maintenance department, the matter of feeding the big tortoise is left to the junior sister, and she goes back to her hometown to celebrate the New Year.

During the Chinese New Year, the staff here in the Northwest were very enthusiastic. Because of the breakthroughs in certain high-temperature resistant materials, the research and development progress of the Solid Killer 3000 was rapid.

One of the difficulties in missile research is the aerodynamic shape. Without a hypersonic wind tunnel, it is difficult to design an excellent aerodynamic shape. The better the aerodynamic shape, the better the flight distance and flight attitude will be.

The second is the engine. The longer the engine runs at full power, the higher and further it can fly.

The third is the control system, which is actually the most complicated. Fortunately, I picked up a wild one a few years ago and it has a complete control system inside.

There were no integrated circuits at this time, so the entire control system weighed [-] kilograms. The circuit board was densely packed with components, as well as high-precision gyroscopes and associated engine control systems.

In the past ten years, the technology of this wild missile has been basically understood, otherwise the 3000-kill missile would not have been released so quickly. The 8000-kill missile has matured and been tested, and the research and development of the [-]-kill missile is proceeding normally.

But engine material technology is a hard nut. The process of this thing is too complex. Even if we can study the ingredients inside, it will be nonsense without process.

If you want to pile up materials, it will cause a series of troubles. The first is the balance weight of the missile itself. The other is that if there are more materials, the power will naturally be smaller. After all, the charge will be small.

There is also the solid rocket motor. The advantages of solid rockets are great. They respond quickly and can be launched maneuverably. Liquid rockets take a while to fill with fuel, and they are also dangerous.

But the solid rocket nozzle, the solid rocket body is actually a shaped gunpowder column inside the projectile, which is the same as the Sky Monkey we launched. It is filled with propellant. The propellant inside has various shapes and various proportions, which will change. The flight speed of the missile and so on, and the most critical material is the nozzle. The longer the nozzle can withstand high temperatures, the farther the missile will fly.

The better the material, the less it is used, and the more powerful the missile is.

Moreover, solid rockets are widely used in air-to-air missiles, anti-aircraft missiles, anti-ship missiles, and submarine launches. It can be said that the control systems of wild missiles picked up have been thoroughly understood. The accuracy and flight control of these missiles have been improved by more than one level.

A solid rocket motor can only travel about 1 kilometers at a time, but if it has a third stage, it can cover more than [-] kilometers.

"There are still capable people in our country."

"Yes, this material has reached the world's advanced technology."

"The American ones are probably more advanced, but the missiles on the American aircraft carriers are much smaller."

"I don't know if that great guy came up with it."

"It's just a few people anyway. When we retire and have time to gather together, we'll know who they are."

"That's true." Anyway, there are only two or three people in the field of high-temperature resistant materials research, but now is the confidentiality period, and everyone is not doing research in the same place. Who has developed these.

"But shouldn't it be time to put matching vehicles on the agenda?"

"This has been fed back. According to our current automobile development, it is not a big problem."

"Not necessarily. The solid rocket launch vehicle requires strong off-road performance, otherwise the grain column may break."

"It should be no problem. Look at our machinery over the years. In the early days, we still used imported cars. Later, we produced our own tractors, four-wheel drive trucks, vans, excavators, forklifts, and cranes. Look at what we used to use before. The crane is in use now.”

"This Kyoto Motorcycle Factory is awesome. I didn't believe it at first. I didn't expect it to produce so many things."

"This factory is really great. The fresh vegetables we can eat now, and the fresh-keeping cold storage built at minus 20 degrees outside, allow us to eat fresh vegetables all year round. It is completely different from when we first came here."

"There are also outdoor living containers, which are also very good."

"Yes."

On New Year's Day, Liu Hai got up in his hometown, stretched and opened the door. It wasn't snowing outside, but the wind was blowing.

Wang Hongmei came out from behind Liu Hai with a glowing face, and then went home. Liu Hai was not surprised, she had been coming here for so many years.

The cold wind was howling outside, Liu Hai closed the door and entered the aircraft carrier space. The largest ginseng inside had been growing for 200 years.

If it hadn't looked like it was growing well, Bang would have dug out the ginseng to prevent it from rotting in the bucket.

In addition, I also cultivated several large barrels of low-year ones that grew very densely, and a Polygonum multiflorum plant.

This Polygonum multiflorum plant is evergreen all year round, so Liu Hai had to come in regularly to harvest the leaves, and then put them in a bucket to act as fallen leaves.

"I have never been able to find a suitable animal experiment." Liu Hai wanted to keep an injured wild animal for experiment while hunting, but unfortunately, the wild animals were very violent.

The key is that the breed is not good. Those who choose to eat meat cannot afford to raise them. It is also difficult to handle them if they are too big. We need to get a few more for comparison experiments.

Moreover, one set of comparative experiments is not enough, and multiple sets of comparative experiments are needed.

"I wonder how long it will take for the fed rats to grow tumors?" Liu Hai was not unprepared, but was conducting experiments on the cultured rats.

Nowadays, there is no place to buy sick rats specially used for experiments.

But Liu Hai has a stupid idea, which is to feed rats moldy feed, which has a high chance of causing tumors in rats.

As for how long it will take, I am not sure. I can only say that I will keep observing.

"It would be great if there were hundreds of rats with tumors for experiments." This idea came to mind.

At noon on the first day of the Lunar New Year, Wang Hongmei brought food from home to eat with Liu Hai. After eating, she took the bowls and chopsticks back.

In the afternoon, Liu Hai had nothing to do, so he took out a book on the kang and read it.

This was a book about medicine in the aircraft carrier space. Liu Hai found that reading this kind of book made his head hurt.

Instead, I read books on machinery and the like with great interest.

"It proves that my talent is not suitable for studying medicine." Liu Hai shook his head and continued to read, mainly to look at the general direction of medicine.

Moreover, in this era, the domestic medical system still focuses on traditional Chinese medicine. Traditional Chinese medicine is all about seeing, hearing, asking, and understanding the five elements of yin and yang. Liu Hai can't even understand it. Of course, Liu Hai has no intention of entering this field.

No one came to disturb me in the afternoon, after all, it was the first day of the Lunar New Year.

Liu Hai didn't even want to go hunting. After all, it would not be good to go hunting on the first day of the new year.

On the second day of the Lunar New Year, Liu Hai went out for a walk with a gun. He met hunters from the next village on the mountain and shot a few ocelots.

Cat skins, no matter what kind of cat skins they are, including ocelot, leopard, tiger skins, and dog skins, are all commodities. Historically, more than 10,000 ocelot skins have been exported, with the highest number reaching more than 20 in a year.

Tigers are not protected animals at this time, let alone a small ocelot.

When I first saw the bangs, I felt a little pity, but then I got used to it, the times are like this.

Liu Hai did not continue into the mountains when he saw other hunters. Wild animals are also very smart. They will run away from hunters when they see them, let alone shoot.

On the fourth day of the Lunar New Year, Liu Hai returned to the city.

The fifth day of the Lunar New Year is Saturday, but the motorcycle factory has not been closed on Sundays recently, so the production task is relatively heavy.

Before arriving at the factory, I could smell the familiar smell of barbecue. When I arrived at the factory, Liu Hai first reported to Sun Aiguo.

Then he walked around the workshop and maintenance department that he supervised, where the junior sister and her two classmates were feeding the big tortoise.Then Liu Hai went to Zhu Haiyang's office to sit for a while, and the two chatted about something about low-speed diesel engines.

After having dinner at the teacher's house at noon, Liu Hai was going back to the maintenance department in the afternoon to start preparing to test the manufacturing of a large transport aircraft.

Just after returning to the maintenance department, Sun Aiguo came: "Director, do you have anything to do with me?"

"The superiors want to build a special car, you take a look first." Sun Aiguo picked up a piece of information and handed it to Liu Hai.

Liu Hai opened the information and looked at it, thinking, do we need this kind of car so early?
The missile transport vehicle is a very special vehicle. This vehicle can be said to be of great significance.

The specific missile transport vehicles are divided into two types, one is a simple missile transport vehicle, and the other is a missile transport vehicle that can both transport and launch.

Let's put it this way, this kind of car is directly related to the survivability rate of missiles.

According to some simulation experiments, if the enemy's entire submarine is covered by Trident missiles, the survival rate of fixed launch silos, including real and fake ones, is less than 10%.

As for the missile launch vehicle, if the speed reaches 40 kilometers per hour, the survival rate will be very high.

This is based on a complex calculation formula, that is, the coverage rate of his Trident missiles, or it is launched from the nearest G island, leaving only 14 minutes at most to react.

To retain sufficient counterattack power, missile vehicles with advanced performance are needed.

Big Brother Next Door initially built missile trains. They also built missile cars and crawler-type ones, but there were too many problems, especially when the grain column in the solid rocket cracked and fractured. Vibration and friction could easily cause accidents. It wasn't until 1985 that Big Brother built a real missile launcher.

It has an off-road speed of 40 kilometers per hour, a wading depth of two meters, can cross a three-meter-wide ditch, and can be launched in relatively flat fields.

Early missile transporters had to be launched on concrete floors.

If the speed is less than 40 kilometers, the survival rate is pitifully low under the first wave of attacks from the opponent.

If the speed is higher than 40 kilometers, then the area that the opponent needs to cover will increase geometrically.

Of course, the missiles needed are also geometric multiples.

It is based on this situation that Big Brother will build missile trains, which can be launched on any railway in the vast Siberia.

Liu Hai looked at the required sizes and felt that we were developing too fast in this area. This size can cost you 3000 lives to transport.

You must know that this is a solid rocket. Most liquid rockets are arranged in fixed launch silos. Of course, there are real and fake fixed launch silos. Anyway, this thing will be on combat duty all year round, that is, it needs to be filled with fuel.

Historically, we have been working hard in this area. We first started in the 70s and 2004s, and later introduced Steyr heavy-duty vehicles. It was not until [-], when we introduced relevant technologies from the Minsk Automobile Factory, that we truly began to possess heavy-duty missiles. Launch vehicle.

Because the heavy missile launch vehicle has very high requirements for the entire vehicle.

However, many years before Liu Hai traveled through time, we were able to produce independently. At that time, there were two domestic factories that could manufacture, one was called Wanshan and the other was called Tai'an Special Vehicle Factory.

In fact, sometimes many factories in the mainland are too low-key. As mentioned before, Juli Group produces blocking locks.

There is also LUO Yang Bearing, a bearing manufacturing group in an island country. High-end bearings occupy a very large share in the world. Later, it was found out that since 16, many of its products were sold at low prices from Luoyang Bearing. It was imported and then OEMed, and there were no problems. Of course, after being discovered, they came out and bowed out.

The last time the newspaper showed it cost you 3000, it was on a trailer frame. Liu Hai was confused at the time, but he couldn't take the initiative to ask about this thing.

"According to logic, there is a factory that can manufacture it?" Liu Hai felt that according to the domestic technical reserves, it can be manufactured.

"It seems that a factory has made it, but after testing it, it didn't work." Sun Aiguo said.

I don’t know how other people design bangs. Since the factory director said so, bangs must contribute.

"I'm afraid this is more troublesome. I'm preparing to build a transport aircraft here." This design is indeed more troublesome. The key is that Liu Hai is preparing to build a large transport aircraft.

"There's no rush for this." Sun Aiguo breathed a sigh of relief after hearing Liu Hai's tone. Liu Hai meant that he didn't have time, not that he couldn't do it.

"Then leave it to me for the time being. Let's wait until I build the large transport aircraft." This design bangs must be designed on a computer in the aircraft carrier space. It can also be designed manually, but it involves too much calculation. .

"How long will it take to start manufacturing a large transport aircraft? Do I need to prepare materials?" Sun Aiguo heard that a large transport aircraft was going to be built, and thought of the DC 7 model, and he was very excited.

"I'll go directly to the equipment department when the time comes."

"Okay, let's build a transport aircraft first. Maybe other factories can manufacture this kind of vehicle later." Of course, Sun Aiguo must build a transport aircraft first. With large transport aircraft and large passenger aircraft, the domestic aviation level will once again rise to a higher level.

"Heavy-duty cross-country transportation equipment!" Liu Hai decided that after finishing the aircraft, he would get this heavy-duty cross-country transportation equipment. The key to this thing is the word "cross-country".

There are many ways to do this thing, but fortunately, in order to cope with war, off-road equipment such as this is made of solid leather and durable, and most of it is mechanical and hydraulic controlled.

Electronic control and the like are rarely used, for fear of a large-scale war. Once a strong electromagnetic wave impact or strong electromagnetic interference is encountered, the entire equipment will be scrapped.

"Director, how about we build a large-scale [-]-ton forging press?" Liu Hai thought he could put this project on the agenda.

"Let's do it ourselves? Are you sure about the technology?" Sun Aiguo certainly knows about large-scale forging presses, which seem to be very difficult.

"Our factory's manufacturing capabilities are barely usable for propeller aircraft, but it's difficult for jet transport aircraft, which require at least a 4.5-ton die forging machine." Liu Hai is ready to let the factory get the project approved first.

At this time, even if you are piling up materials, you can still pile them out, enter the threshold first, and then optimize later.

However, according to the strength in the factory, it still feels a bit difficult, but there are some things that you still have to do even if you know they are difficult.

"I'll report to the leader." When Sun Aiguo heard the word jet transport, he felt that he wanted to start this project, but he still had to report what should be reported.

In fact, this kind of ultra-large forging equipment will be a loser after production, because the application range is not very wide, and it is widely used in aerospace. After all, an aircraft produced can fly for at least several decades.

Of course, building one of this thing can last for many years. Big Brother built it a few years ago and it was still in use when Liu Hai traveled through it.

That thing can be given away to generations of people without any problem. It is just a big iron lump, a hydraulic cylinder with a diameter of one or two meters, and the overall appearance is almost the same as a small four-column hydraulic press.

It just changed from something over two meters high to dozens of meters high and weighing thousands or tens of thousands of tons.

Die forging machines are mainly used for hot die forging and isothermal superplastic forming of difficult-to-deform materials such as aluminum alloys, titanium alloys, high-temperature alloys, and powder alloys.

"By the way, there is another thing. The sports car we made for Big Brother, those shameless people made and sold it themselves, and said that they designed it themselves." Sun Aiguo told Liu Hai another thing.

"Big Brother's camp doesn't have any patents." Liu Hai could only smile bitterly.

"I plan to report to the leader. Since Big Brother is shameless, let's open up production." Sun Aiguo asked.

The reason why Sun Aiguo wants to listen to Liu Hai's opinion is because Liu Hai is in charge of the sports car stall.

"I listen to the leader on this. If Big Brother has anything good, ask the leader to bring some back. We will also produce their products." Liu Hai said with a thought in his heart.

Big Brother still has a lot of good stuff these days, especially heavy equipment.

"This is a good idea. I'll go ask for instructions." Sun Aiguo's eyes lit up. This is a good idea.

Watching Sun Aiguo leave in a hurry, Liu Hai shook his head and looked forward to what equipment the leaders would buy back for him to copy.

"Prepare to build a large transport aircraft." Liu Hai still prepares to build our propeller four-engine transport aircraft first.

This thing just needs to share ground handling with the twin-engine transport aircraft, and the maintenance is basically the same. As long as you learn the maintenance manual for the twin-engine transport aircraft, you can maintain this propeller four-engine transport aircraft, which can greatly reduce maintenance costs.

　The second update is a bit more.
