Fighter jets need good engines.

Of course, transport aircraft also need good engines.

Fighter jets need speed, agility. What the transport aircraft needs is high thrust and strong load.

In the past, the Soviet Union's An-225 transport aircraft was a real giant. The take-off weight is more than 600 tons, the payload is more than 300 tons, and the cruising range is 15,400 kilometers.

In front of it, what Airbus A380, what Boeing 747, all are scum.

Our country, of course, also wants to have the An-225.

However, alas, out of reach.

China's latest model of military transport aircraft is the Y-20, with a maximum take-off weight of 220 tons and a payload of more than 60 tons. That's about one-fifth the size of the An-225.

Well, a fifth.

The weight of a heavy main battle tank.

The maximum range is about 7800 km. That's about half the size of the An-225.

The key is the thrust of the engine.

The C-17 transport aircraft of the US imperialism has a single engine thrust of 18 tons. And the single thrust of our country is only 12 tons. Only two-thirds of the other side. The gap is big, big.

The US imperialists also have a giant transport aircraft, that is, the C-5 Galaxy. It has a carrying capacity of more than 120 tons. The maximum take-off weight is 380 tons.

Why is it so strong? It's all about the engine!

Of course, the emergence of the Y-20 has also greatly changed the status quo of China's air force transportation.

Specifically, the Y-20 can transport most of the technical equipment currently equipped by the Chinese Army, including main battle tanks, armored vehicles, self-propelled guns and helicopters. If there are 100 Y-20s, one mechanized infantry regiment can be delivered to a distance of 5,000 kilometers at a time. If it is only to transport soldiers, then 100 Y-20s can send an infantry regiment to a distance of 7,000 kilometers at a time, so that the Chinese army initially has a global strategic projection capability.

From a strategic point of view, the emergence of the Y-20 can almost be compared with domestic aircraft carriers.

The only problem is that it needs a much stronger heart.

At a minimum, the payload of the Y-20 needs to be increased to more than 100 tons. The maximum range is more than 10,000 km. And it has all-weather take-off and landing capabilities.

How does a powerful engine come about?

It requires bold designs, and strong raw materials.

Does Wang Buan have it?

Yes!

He has a package of solutions.

If it were left to him for design, he would have been able to increase the payload of the Y-20 to more than 150 tons.

At the same time, the maximum range increased to more than 15000 km.

It can also be equipped with more advanced electronic equipment. Ability to take off and land in any climate.

Even, even in the face of violent storms and snowstorms, this behemoth can be as if it is a giant and is not afraid.

However, he did not have such power.

This is the strategy of the state. is top secret. It will not be designed by a private person.

Unless he has the full trust of the state.

"I don't understand the technology. Wang Buan deliberately said modestly, "But I can provide you with a hydraulic press and a CNC machine." ”

"We have our own businesses to work with. Han Xuewei shook her head and said.

"But you don't have a 100,000-ton hydraulic press, and you don't have a 1-micron CNC machine. ”

"Are you sure you're right?"

"Of course not. ”

Wang Buan replied very calmly.

How could it be wrong?

This data is much easier to remember than that of a lithography machine.

Han Xuewei looked at Cheng Kailong.

Cheng Kailong was also a little surprised.

Han Xuewei was surprised by the 100,000-ton hydraulic press.

Cheng Kailong was surprised by the 1-micron five-axis CNC linkage machine tool.

Immediately, Han Xuewei also reacted.

A 1-micron CNC machine? That's a cutting-edge product.

At present, in the world, the accuracy can reach more than 0.05 mm, which is a precision machine tool. How much is 0.05 mm? 50 microns!

Between 1 micron and 50 microns, the difference is too far. It was also difficult for him to accept it for a while.

"Engine parts require extreme precision, maybe you can use them?" Wang continued.

"If the accuracy of CNC machines can really reach 1 micron, then we definitely need it. Han Xuewei said slowly.

"CNC machines are expensive. I don't think you can afford it. It's better to rent it to you for use. The rent is 10,000 yuan per day. A 100,000-ton hydraulic forging machine is given as a gift. ”

"10,000 yuan a day? Why don't you talk about 100,000 yuan a day?"

"Miss Han, the CNC machine I provided is definitely worth the money. ”

"I'm sorry, I don't have the right to decide. ”

"That's a pity. ”

"I want one. Cheng Kailong said suddenly.

"Thank you very much. Wang Bu'an smiled, "But what are you going to do?"

"It worked. Cheng Kailong did not answer positively.

"Good. Deal. Wang Buan did not continue to ask.

Others are confidential units, don't be boring.

Anyway, with a rent of 10,000 yuan a day, you just don't have to be in arrears.

Speaking of which, the rent of 10,000 yuan a day is really too cheap! It is a five-axis CNC machine tool with an accuracy of 1 micron!

For large forgings, you can find Huaxia Erzhong and forge them with an 80,000-ton hydraulic press.

But who do you go to for parts with an accuracy of 1 micron?

There are no 1 micron machine tools in the world.

"But you need to solve the transportation yourself. Wang Buan added.

"No problem. Look at the goods first. Cheng Kailong nodded.

"No problem. You can watch it anytime. However, I only have one set at the moment. Hold on if you want it. ”

"Wang Buan, you are becoming more and more like a profiteer now. ”

"The traitor will give you such a good price?"

"Who else will easily trust you but us?"

“……”

Wang Buan had no choice but to shut up in amusement.

There's no way, there are so many people who know the goods. Cheng Kailong is barely one.

Han Xuewei is definitely ignorant of goods.

She simply didn't believe that there was a machine tool with an accuracy of 1 micron in the world.

No wonder the Yun-20's heart has not progressed for a long time......

Without the right equipment, no matter how well you design, you won't be able to start experiments!

You know, the test process of the engine is very cumbersome. At least five or more engines need to be prepared, and then trial and error until all of them are scrapped.

If you want to get more test data, you need to prepare at least ten engines.

Without accurate five-axis CNC linkage machine tools, where can there be so many precision parts?

Relying on senior fitters to get out one by one?

It is impossible to produce in large quantities with manpower.

No matter how good the fitter is, it is impossible to meet the needs of the production line.

Only CNC machine tools can increase production capacity.

"For you. ”

"What's that?"

"You'll know when you look at it. ”

"Really?"

Han Xuewei frowned slightly.

What Wang Bu'an handed over was actually a notebook.

Very old notebook. Plastic cover. The one with a lock. The size should be 32 open.

"I don't look. Han Xuewei shook her head and said.

"It's fine. Look at it slowly when you have time. "Wang Buan doesn't care.

In the notebook, it is actually the basic idea of the engine of the Y-20 aircraft designed by him. According to this idea, it is absolutely possible to produce a single engine with a thrust of more than 30 tons.

At present, the world's largest thrust engine is the F-135 of the US imperialists, with a single thrust of just more than 20 tons.

The thrust of a single aircraft engine of 30 tons designed by him completely crushed this value.

It's a pity that Han Xuewei seems to have misunderstood.

She naively thought that there was something in the notebook.

Women really can only be used for eye-catching.

How can the research project of the Y-20 aircraft allow the existence of women? Long hair and short knowledge......

"You've straightened your senses. ”

"You gained 10,240 Faith. ”

"You have contributed to the defense industry. ”

"You gained 10,240 Faith. ”

Suddenly, a message flashed.

Wang Bu'an can understand the following information. Except for the first one......

What does it mean to correct one's own understanding?

Think Han Xuewei is not suitable to participate in the research of large aircraft projects?

It's really strange that such an idea can also gain faith points? It seems that it can really be earned without work!

What can you do with 20,000 faith points?

"When I'm ready, I'll go to you. Cheng Kailong said.

"You can send me away now. I don't want to watch it. Wang Buan said, "I'll wait for the result." ”

"It's fine. I'll send you back first. ”

"Thank you!"

The two left the military base.

After walking out of the scope of the military restricted area, Wang Buan silently breathed a sigh of relief.

He felt like he was finally free.

Check your watch.

Three missed calls. A message. Five WeChat.

I thought I was busy, but when I opened it, I found that it was all harassing calls and spam messages. WeChat is also full of advertisements.

It's not that the No. 1 robot elf can't isolate these introverted information.

It's this guy who doesn't want to at all.

It also finds the harassment messages quite funny.

It will even interact with the attack information. Or play stupid and lure the other party into taking the bait. until they break the other person.

These anti-routine knowledge are all learned by the robot elves from Wang Buan's mind.

In the past, when Wang Buan was bored, he specialized in doing this kind of thing that harmed others and was not beneficial to himself. It's purely to pass the time.

However, in the past, he was a human brain after all, and he would be tired.

Once you feel tired, you don't want to continue.

However, the No. 1 robot elf is very happy.

It even gathers other robot elves to counter the intrusive information.

Organized.

There is a plan.

There is scale.

Legion combat. Large corps operations.

What kind of effect has been achieved, Wang Buan is not clear for the time being. But it's going to be a lot of money when you think about it.

To rectify telecom fraud, it may rely on Transformers.
