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

Then Donald ordered special glass and bearings of about 5,000 energy coins from Wang Bin, and then he took out the technology he brought this time.

Donald took out a stack of blueprints, handed them to Wang Bin, and said to Wang Bin, "This is the technology I want to use to deduct the purchase of 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 the blueprint was somewhat beyond his expectations.

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

However, in fact, the technology that Donald gave him is not simple. Even if it cannot be compared with Wang Bin's world-class technology, there may still be a little gap, but it is also of very high value, and even most countries in the world have no Unable to manufacture things in blueprints.

Wang Bin can be sure that the technology in the drawings is definitely the top technology in Donald's world, or strategic technology.

The technology that Donald presented was an aero-engine technology, and it was also a turbojet aero-engine technology.

The most important thing is that according to the data on this blueprint, the specific impulse produced by this engine has actually reached about 11. This is what surprised Wang Bin the most.

Even in Wang Bin's world, there are not many countries that can produce jet turbojet engines.

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

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

Although the thrust of a single engine has reached about 18 or 19 tons, its engine specific impulse is only about 10.

However, Donald's world, their country, is actually capable of producing an aero-engine with a specific impulse of eleven, how could this not surprise him!

According to the normal development of science and technology in the world where Wang Bin lived, his country had already developed and produced jet aircraft engines in the late World War II.

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

Seeing Wang Bin's expression, Donald knew what Wang Bin was thinking, and said at this time: "Mr. Wang! In fact, this blueprint was not completely designed by our country.

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

Therefore, after the experts in our world designed this engine, I searched for a professional engine design shop in the mall, and made substantial design modifications to complete the design of this engine.

However, even so, with the technological level of our world, the performance of the manufactured engine can only reach about 80% of the design data, which is about 9 impulse ratios.

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

Wang Bin nodded, and at the same time secretly asked the system; "System, may I ask the technical blueprint that Donald brought over this time, how is its performance, how is the technical integrity, and how many energy coins can be deducted?"

Although Wang Bin has a certain understanding of aero engines, it is actually limited to ordinary people, and even compared with those military enthusiasts, it is not as good.

Therefore, of course, the technical performance of this engine cannot be known exactly. The best way is to ask the system.

"Host! According to the data identified in this blueprint, the maximum length of the engine in the blueprint is 4.9 meters, the maximum diameter is 1.1 meters, the maximum diameter of the nozzle is 0.61 meters, the self-weight is 1.0 tons, and the maximum thrust is 120 kN.

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

At the same time, the technical integrity of the engine in this drawing, except for the engine material technology, is 100% technical integrity. According to the system appraisal, the deduction price of this engine blueprint should not be less than 10,000 energy coins. The system recommends that the minimum energy coin of 10,000 price to purchase. "Just after Wang Bin finished asking, the system gave the price for purchasing this engine.

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

However, the price of acquiring the technology of this engine from Donald was only 10,000 energy coins, which made him feel that buying technology from the system was really expensive.

But then he understood why the price of the technology sold by the system was so high.

This is because the technology sold to him by the system will directly instill the technology into his mind, and there is nothing impossible to understand.

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

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

However, the price of the knowledge instilled in the mind by the system is not comparable to the technology itself, so the price of purchasing from the system is high.

Wang Bin, who came back to his senses, said to Donald: "Mr. Donald! This engine technology of yours may already be the top aviation technology in your world.

Compared with the world I live in, your engine technology is still not comparable to those engines with real high performance.

However, as our Tiangong technology, the most basic aviation development in the real world where I live will be enough in the future, so I also accept this technology. As for the deductible price, it will be based on the price identified by the system, 10,000 energy Let's count the coins! "Wang Bin said.

Donald nodded and said, "Yes, Mr. Wang! Just calculate according to this price."

Donald was not surprised by the price given by Wang Bin. In fact, when he brought the technical drawings and data of this engine to the mall, he had already let the system appraise it, so the price was in his hands. Already know.

Afterwards, Wang Bin and Donald chatted again, and they returned to their own worlds respectively.

As for the extra energy coins, Wang Bin did not give them directly to Donald, but directly withheld them in his own hands, and settled the settlement after he next purchased their Tiangong technology products.
