Chapter 46 An airplane from 5100 years ago?

“Yes, we do want to import one or several engines of specified models!” Zheng Zeyao nodded.

Seeing what the other party said, Luo Feng frowned and said, "Brother Yao, it's not me. There is a saying that you need to be strong to make iron. You want raw materials and equipment, I Everyone can help. But in a core area like aviation, you can’t always think about imports, you have to do it yourself. It’s in your hands!”

“Who says it’s not true? But at present, there is no way in the country. If you can do it yourself, you won’t be able to import it!”

Zheng Zeyao heard this. , Although I agree with Luo Feng's point of view, it backfires. Aviation technology is not that 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 boss want this time?"

"Actually, Xiao Luo, Regarding aviation equipment, what I mean above is, if you can get it, go for it. If you can’t get it, you can’t force it. After all, The boss still hopes to do long-term business with you. If the knife is sharpened too fast, it will be easy to use, but it will also break easily!"

After hearing Zheng Zeyao's words, Luo Feng smiled slightly. It seems that the military industry is also interested. I know that if I want Luo Feng to get aviation-related equipment, I am afraid that something will go wrong with Luo Feng, and then the line will 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 be careful. Tell me, what type of engine do you need?" Luo Feng nodded happily and asked again.

"Jet type!"

"Oh? Got it!"

An hour later, Luo Feng wanted to go to Su Li's dinner, but he called and said something happened Don't go.

Su Li and Tingting are 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 checking 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 aircraft engines is very high, reaching 70 to 80%, while the conversion rate of ordinary automobile oil is only 20 to 30%.

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 a breakthrough in technology.

In today’s China, technological breakthroughs are precisely the shortcomings.

In fact, many years ago, our country’s aero engines had a thrust-to-weight ratio 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 flaw, which is the reliability of working hours.

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

Aeroengines must not only be manufactured based on their strength on paper, but also their actual practicality, and they must be able to operate for a long time.

For example, the most advanced engine currently is the F135, which is developed on the basis of the F119. 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.

So, for aero engines, the domestic shortcomings are breakthroughs 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. After helping Xiaomei put it on, he asked: "Xiaomei, at the exchange, I checked last time. Is there anything about ancient aerospace?" An antique airplane?”

“Yes, I remember it!”

“Then let’s go take a look?” Luo Feng took a few steps toward the door.

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

Luo Feng nodded, and he also knew this, that is to say, he You need 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 also troublesome! I really want to blow up that exchange!"

Luo Feng is scratching his head. This time, it is impossible to exchange used cars.

I am afraid that hundreds or thousands of vehicles will be useless.

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

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

"Forget about all that, let's go to the exchange and look at the past transaction records. These antique aircraft must be exchanged for some cultural relics!"

"Okay, master, we Let’s go!”

The two of them had no ink marks. Luo Feng released the 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, because Luo Feng often comes here, it seems that Xiaomei has protected this place.

There is a protective net around the perimeter. Under such circumstances, the sand and dust will not creep into it.
