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

Chapter 46 An airplane from 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 nothing we can do in China. If we can do it ourselves, we 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 these things could not be rushed, so he waved his hand and said: "Okay, let's not talk about this anymore, just go for it. Tell me, what does the higher up want this time?"

"Actually, Xiao Luo, regarding aviation equipment, what the higher-ups say is, if you can get it, go for it. If you can't get it, you can't force it. After all, the higher-ups still hope to do long-term business with you. If the knife is sharpened too fast, it is indeed easy to use. , but it’s also easy to break!”

After listening to Zheng Zeyao's words, Luo Feng smiled slightly. It seemed that the military industry also knew that if Luo Feng was asked to work on aviation-related equipment, they were afraid that something would go wrong with Luo Feng and the line would be broken.

After all, various countries are still very strict about 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 attend Su Li's dinner, but he called and said something was going on.

Su Li and Tingting were also very sorry.

Tingting even cried a little, saying that her brother Luo Feng was obviously coming, 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, starting to check the information.

After looking at it for a while, Luo Feng also had a preliminary understanding of jet engines.

The working principle of this thing is to suck in air, compress it and heat it.

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, that thing has to fly into the sky and cannot carry too much energy. If humans want to make a breakthrough, they must improve energy utilization.

Now in China or around the world, aeroengines can have a thrust-to-weight ratio of about 10, which is the peak. In recent years, there have been no breakthroughs at all. The only breakthroughs in research and development are safety, speed, and functionality.

These three are collectively called breakthroughs in technology.

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

In fact, many years ago, our country's aero engines had thrust-to-weight ratios of 9 or 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 drawback, and that is the reliability of working hours.

For example, the engines of the J-10 fighter jets and some equipment are imported Russian equipment.

The manufacturing of an aerospace engine cannot be based solely on its strength on paper, but its actual practicality, and it must be able to operate for a long time.

For example, the most advanced engine currently is the F119, which is developed on the basis of the F135. It has 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 weight-to-weight ratio can be developed domestically, but if the working time does not exceed eight hours, then what is the point of manufacturing it?

Is it just that the data looks good?

With a car, your top speed is indeed very fast and the horsepower is very strong, but if it is not good in other aspects, it is of no use at all.

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

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

If we can obtain several high-level engines for research and provide auxiliary information, it will definitely save a lot of time and energy on the part of the military industry.

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

"Master, welcome home!"

"Xiaomei, let me change the battery for you first. Is there anything abnormal here in the past few days?"

"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 it!"

"Then let's go take a look?" Luo Feng took a few steps toward the door.

"Master, antiques related to ancient space shuttles are basically the most valuable among ancient machines!"

Luo Feng nodded and knew this, which meant that he needed to use very expensive antiques to trade, otherwise there would be 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'm afraid hundreds or thousands of vehicles will be useless.

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

In other words, this is like a national treasure-level cultural relic from China. How can it be measured by money?

"Forget it, let's go to the exchange and look at the past transaction records. These antique airplanes must be exchanged for some kind of cultural relics!"

"Okay, Master, we're going over there right now!"

There were no ink marks on either of them. Luo Feng put out his off-road motorcycle, and Xiaomei hugged Luo Feng's waist and sat in the back.

Heading towards the exchange more than 100 kilometers away.

Looking at the perimeter of the exchange, it seemed that Xiaomei had protected the place since Luo Feng came here often.

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