Let you recycle scrap metal and bring back a 10,000-ton battleship

Chapter 46 Aircraft 5100 years ago?
"Yes, we do want to import one or several engines of a specified model!" Zheng Zeyao nodded.

Seeing what the other party said, Luo Feng frowned fiercely, and said: "Brother Yao, I didn't say it. There is a saying that you need to be strong to forge iron. If you want raw materials and equipment, I can help you. But in the core area like the aviation field, you can't always think about importing, you have to be in your own hands!"

"Who says it's not? But at present, there is no way in China. If you can handle it yourself, you won't import it!"

Hearing this, Zheng Zeyao agreed with Luo Feng's point of view, but things went against his wishes. Aviation technology is not so easy to develop.

Luo Feng also knew that there was no rush for these things, so he waved his hands and said, "Okay, let's not talk about this, you just have to work hard. Tell me, what do you want this time?"

"Actually, Xiao Luo, regarding the aviation equipment, the above means that if you can get it done, go there. If you can't get it done, you can't force it. After all, the above still hopes to trade with you for a long time. If the knife is sharpened too fast, it is indeed easy to use, but it is also easy to break!"

Hearing Zheng Zeyao's words, Luo Feng smiled slightly. It seems that the military industry also knew that if Luo Feng was to be engaged in aviation-related equipment, he was afraid that something would go wrong with Luo Feng, and then the line would be cut off.

After all, various countries still have strict checks on aviation-related equipment, unlike rare earths, electrolytic nickel, or some high-end machine tools, which are relatively easy.

"Thank you for your concern. I will act carefully. Tell me, what type of engine do you need?" Luo Feng nodded in relief and asked again.

"Jet!"

"Oh? Got it!"

An hour later, Luo Feng wanted to go to Su Li's dinner, but he called and said that there was something he couldn't handle.

Su Li and Tingting are also very sorry.

Tingting also cried a lot, saying that brother Luofeng was going to come, but her mother wouldn't let him come.

It also made Su Li speechless.

At this moment, Luo Feng was already in front of the computer at home, and started to check the information.

After checking for a while, Luo Feng also had a preliminary understanding of jet engines.

The working principle of this thing is to inhale air, compress it and heat it up.

The energy conversion of aero-engines is very high, reaching [-] to [-] percent, while the conversion rate of ordinary automobile oil is only [-] to [-] percent.

After all, if that thing wants to fly into the sky, it cannot carry too much energy. If human beings want to break through, they must increase the efficiency of energy utilization.

At present, in China or in the world, aero-engines can have a thrust-to-weight ratio of about 10, which is the peak. In recent years, there has been no breakthrough at all, and research and development are only breakthroughs in safety, speed, and function.

These three are collectively referred to as technological breakthroughs.

But in today's country, technological breakthroughs are precisely the shortcomings.

In fact, many years ago, my country's aero-engines had thrust-to-weight ratios of 9 and 9.5, and even the J-series now have a thrust-to-weight ratio of 10.

already at an advanced level.

But there is also a big flaw, that is, the reliability of working hours.

Just like the engine of the J-10 fighter jet, some equipment is imported from Russia.

The manufacture of an aero-engine should not be based solely on its strength on paper, but on its actual practicability, and it must be able to fight for a long time.

For example, the most advanced engine at present is the F119 developed on the basis of the F135, with a maximum thrust of more than 18 tons and a thrust-to-weight ratio of more than 10.

It is the world's top level, but such a thrust-to-weight ratio can also be developed in China, but if the working time does not exceed eight hours, then what is the significance of manufacturing it?

Is it simply that the data looks good?
A car, your top speed is indeed fast, the horsepower is very strong, but it is not good in other aspects, it is useless at all.

Therefore, for aero engines, the domestic defect is the breakthrough in technology.

However, breakthroughs in technology are often blocked by other countries, and technical exchanges cannot be obtained.

If several high-level engines can be obtained for research and supplemented with auxiliary materials, it will inevitably save a lot of time and energy on the military side.

After checking the information, Luo Feng held the ring in his hand, and after a few minutes, he was already on the Tianyuan planet.

"Master, welcome home!"

"Xiaomei, let me change the battery for you first. In the past few days, there is nothing abnormal here, right?"

"Master, there is nothing abnormal!"

Luo Feng nodded, and then found the battery board in the drawer in the camp, and after helping Xiaomei replace it, he asked: "Xiaomei, the exchange, I checked last time, is there an antique about the ancient space shuttle?"

"Yes, I remember!"

"Then let's go and have a look?" Luo Feng walked a few steps towards the door.

"Master, the antiques about the ancient space shuttle are basically the most valuable among the ancient machines!"

Luo Feng nodded, knowing this too, that is to say, he needs to use very expensive antiques to trade, otherwise there is no hope.

Machines like ancient machine tools are not very valuable.

But ancient aircraft are expensive antiques.

"It's troublesome too! I really want to blow up that exchange!"

Luo Feng scratched his head, this time, it would not work at all if he wanted to exchange it with a scrap car.

I am afraid that hundreds or thousands of vehicles are useless.

Because antiques like airplanes basically cannot be traded with money, but with antiques of comparable value.

In other words, this is like a cultural relic of the national treasure level in Huaxia, how can it be measured by money.

"Don't worry about that much, let's go to the exchange and look at the previous transaction records. These antique planes need to be exchanged with some cultural relics!"

"Okay, master, let's go there!"

There was no ink marks on the two of them, Luo Feng released the off-road motorcycle, Xiaomei put her arms around Luo Feng's waist, and sat in the back.

Heading towards the exchange more than 100 kilometers away.

He looked around the exchange, because Luo Feng came here often, it seemed that Xiaomei had already protected the place.

There is a protective net on the outside, so under such circumstances, the sand and dust will not spread into it.
