"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. If you want raw materials or equipment, I can help. But aviation

In a core area like this, we can’t always think about imports, we have to take control of them ourselves!”

"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!"

When Zheng Zeyao heard this, although he agreed with Luo Feng's point of view, it turned out to be contrary to expectations. 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 do you want this time?"

"Actually, Xiao Luo, regarding aviation equipment, what the higher-ups say is that 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 engage in aviation-related equipment, they were afraid that something would go wrong with Luo Feng and the line would be broken.

After all, various countries have very strict control over 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!"

"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 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 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 aerospace 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, aviation engines 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 referred to as technological breakthroughs.

But today's domestic breakthroughs in technology are just 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.

It is already at an advanced level.

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

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

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

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

For 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 completely useless.

Therefore, for aero engines, the domestic defects are breakthroughs in technology.

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

If we can obtain several high-level engines for research and provide auxiliary information, it will definitely save a lot of time and energy in 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, over there at the exchange, I checked last time. Is there anything about ancient aerospace?"

Airplane antiques?"

"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 he also knew this, which meant that he needed to use very expensive antiques to trade, otherwise there would be no hope.

Machines such as ancient machine tools are not very valuable.

But ancient airplanes are expensive antiques.

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

Luo Feng scratched his head. This time, it was impossible to exchange the scrap car.

I'm afraid hundreds or thousands of vehicles will be useless.

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

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

The two of them had no ink marks. Luo Feng put out his off-road motorcycle, and Xiaomei hugged Luo Feng's waist and sat behind.

Heading towards the exchange more than 100 kilometers away.

Looking at the perimeter of the exchange, it seems that Xiaomei has protected this place since Luo Feng comes often.
