"Yes! I don't know if what you need to buy this time is special glass or bearings? Or both?" Wang Bin nodded and said after listening.

Then Donald ordered about five thousand energy coins for special glass and bearings from Wang Bin, and then he took out the technology he brought this time.

Donald took out a stack of drawings and handed it to Wang Bin, and said to Wang Bin: "This is the technology I want to use to deduct these products this time!"

And Wang Bin took the blueprint in Donald's hand and looked at it for a while, and he found that the technology in this blueprint was somewhat beyond his expectations.

Originally, he thought that Donald’s first deduction would not be too advanced, and at the same time it would not be their world’s top technology.

However, in fact, the technology Donald gave him is not simple. Even if it cannot be compared with Wang Bin's world-class technology, there may be a little gap, but it also has a very high value. Even most countries in the world simply Can't make things in the drawings.

All Wang Bin can be sure that the technology in the drawings is definitely the top technology in the world where Donald is, or a strategic technology.

Donald’s technology is an aero engine technology and a turbojet aero engine technology.

The most important thing is that if according to the data on this drawing, the specific impulse produced by this engine actually reaches about eleven, this is what surprises Wang Bin the most.

Even in the world where Wang Bin lives, there are not many countries that can produce jet turbojet engines.

But it is not very few, there are at least a dozen, but there are very few countries that can produce high-performance engines.

In particular, countries that can produce engines with a specific impact of more than ten are even rarer, even the fourth-generation engine of the Bald Eagle.

Although the thrust of a pair of f engines has reached about 18 or even 19 tons, its engine specific impulse is only about ten.

However, Donald's world, their country, has the ability to produce aero engines with a specific impulse of eleven. How could this not surprise him!

If you look at the technology and normal development of Wang Bin’s world, in the latter part of World War II, their country had already developed and produced jet engine engines.

However, the technology is still at a very primitive stage and it is impossible to achieve this level.

Donald saw Wang Bin's expression and knew what Wang Bin was thinking. Then he said, "Mr. Wang! Actually, this drawing was not entirely designed by our country.

Presumably Mr. Wang, you also know that the level of science and technology in my world, even if I have concentrated most of the outstanding aero engine experts in my country, the jet engine designed by me still has many defects, and the specific impulse is the highest. Only 7-8.

So experts in our world, after designing this engine, I searched for a professional engine design shop in the mall and made substantial design changes to complete the engine design.

However, even so, with our world's technological level, the performance of an engine manufactured can only reach about 80% of the design data, that is, an impact ratio of about nine.

This is the reason why we have already used a lot of the bearings and other accessories provided by Mr. Wang. If you do not use these materials and accessories provided by Mr. Wang, it will be very difficult to reach nine."

Wang Bin nodded, and at the same time asked the system secretly; "System, I would like to ask Donald about the technical drawings he brought this time. What is its performance, technical integrity, and how many energy coins can be deducted?"

Although Wang Bin has a certain understanding of aero engines, in fact it is only limited to ordinary people, even if compared with those military enthusiasts, it is not as good as that, so of course it is impossible to know exactly the technical performance of this engine. There is no better way than to ask the system.

"Host! According to the data of this drawing, the engine in the drawing has a maximum length of 4.9 meters, a maximum diameter of 1.1 meters, a maximum nozzle diameter of 0.61 meters, a dead weight of 1.0 tons, and a maximum thrust of 120 kN.

The technical performance is very good for the host world, and has reached the international advanced level of the host world.

At the same time, the technical integrity of the engine in this drawing, except for the engine material technology, is 100%. According to the system appraisal, the deductible price of this engine drawing shall not be less than 10,000 energy coins. The system recommends the minimum energy currency of 10,000 Price for acquisition."Just as Wang Bin finished asking, the system gave the price for acquiring this engine.

Wang Bin is still a little surprised at the price given by the system. In the system, the price of an engine with similar performance to this engine is as high as 100,000 yuan.

However, from Donald, the price of acquiring the technology of this engine is only a mere ten thousand energy coins, which makes him feel like buying technology from the system is really expensive.

But then he understood why the technology sold by the system was so expensive.

This is because the technology sold to him by the system will directly instill the technology into his mind, and there is no situation that cannot be understood.

It even includes some other related technologies, such as how to build the production line.

So in fact, the price of the technology purchased in the system is not high, even lower than the one he purchased from Donald.

However, the price of the knowledge that the system instills into the mind is not comparable to the technology itself, so the price of buying from the system will be higher.

After returning to his senses, Wang Bin said to Donald: "Mr. Donald! Your engine technology may already be the top aviation technology in your world.

Compared to the world where I live, your engine technology still cannot be compared with those truly high-performance engines.

However, as our Tiangong Technology, it will be enough for the first-level aviation development in the real world where I am in the future. Therefore, I also accepted this technology. As for the deductible price, it is based on the price identified by the system. Let's count the coins!"Wang Bin said.

Donald nodded and said, "Yes, Mr. Wang! Just calculate it at this price."

Donald was not surprised by the price given by Wang Bin. In fact, when he brought the technical drawing data of this engine to the mall, he had already asked the system to appraise it, so this price was in his I knew it a long time ago.

Then Wang Bin and Donald talked again, and they returned to their own worlds.

As for the extra energy coin, Wang Bin did not directly give it to Donald, but directly detained it in his own hand, and waited for the next time he purchases their Tiangong technology products before making a settlement.
