Chapter 106 (1/2)

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

Then Donald ordered about 5000 energy coins of 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, handed them to Wang Bin and said to Wang Bin, ”this is the technology I want to use to offset the purchase of these products this time!”

Wang Bin took the drawing in Donald's hand and looked at it for a while. He found that the technology in the drawing was somewhat unexpected.

Originally, he thought that Donald's deduction for the first time would not be too advanced, and it could not be their world-class technology.

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

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

Donald's technology is an aeroengine technology and a turbojet aeroengine technology.

Most importantly, according to the data on this drawing, the specific impulse produced by this engine actually reached about 11, which surprised Wang Bin most.

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

However, there are not very few, at least a dozen, but few countries can produce high-performance engines.

In particular, there are 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 F-22 engine reaches about 18 or even 19 tons, its engine specific impulse is only about 10.

However, Donald's world, his country, has the ability to produce aeroengines with specific impulse up to 11. How can it not surprise him!

According to the normal development of science and technology in Wang Bin's world, although their country had developed and produced jet aircraft engines in the late World War II.

However, the technology is still in 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. At this time, Donald said, ”President Wang! In fact, this drawing is not completely designed by our country.

As you must know, President Wang, the level of science and technology in my world, even if I have gathered most of the excellent aero-engine experts in my country, the jet engine designed by me still has many defects, and the highest specific impulse is only 7-8.

Therefore, after the experts in our world designed this engine, I found a professional engine design shop in the mall and made substantial design modifications to it before completing the design of this engine.

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