The Reborn Scholar Wants To Counterattack

The explanation principle is relatively complicated, but what ordinary people can intuitively understand is:

Large bypass ratio engines have lower fuel consumption, better propulsion efficiency, higher economic performance, and stronger stability than engines with small bypass ratios.

Of course, the corresponding manufacturing requirements are also higher. For example, the fan blades of the former are at least more than one meter, while the fan blades of the latter only need about 0.3-0.4 meters.

Take a very high-end engine as an example:

The maximum temperature inside the engine produced by Rolls-Royce for the A380, a country where the sun never sets, reaches half the surface of the sun!

The pressure inside the engine reached 50 atmospheres!

The turbine blade tip moves at a speed of 2,000 kilometers per hour, and its blades are more than 3 meters long...

In short...these four highs and two lows are simply a curse for manufacturing large civilian aircraft engines.

And because of this, the aviation manufacturing industry generally represents the manufacturing level of a country.

In the eyes of first world countries, China is naturally a poor and backward country that can only exist as a downstream supplier.

The people present also represent, to a certain extent, China’s top scientific research figures.

Everyone knows this very well.

But just because they knew it but were unable to change it, this sense of urgency and mission made everyone more depressed and silent.

Gu Weimian nodded slightly,

"In addition to the above problems, the materials and processes of the engine are also a major difficulty."

Materials science is partly the cornerstone of the nation's manufacturing industry.

It also limits the development of a country's manufacturing industry.

Not to mention the big ones.

Just plain concrete.

In this world before she came back.

That is to say, in 2018, China's concrete was not as good as Yamato's.

As a country with a large amount of steel and even excess steel production capacity, China did not have the most first-class special steel and needed to import a large amount of it.

Without good enough materials, some high-precision parts cannot be conquered.

For example: how to withstand the terrifyingly high temperatures of a regional jet engine without melting the entire barrel wall.

How can we ensure that under the pressure of 50 atmospheres, the cylinder wall will not be fragmented or deformed?

She looked at Fan Yanqing,

"Teacher Fan, you are a true master. You have solved big problems and difficulties for our China Airlines, and finally fired the first shot for our China Airlines."

She stood in front of the airplane model with a sincere and enthusiastic attitude.

With shining eyes, he looked like a simple Chinese, admiring him and thanking him.

Fan Yanqing's throat seemed to be blocked.

The corner of Ning Yuetong's mouth that had just been raised was forced back when she saw Fan Yanqing's face.

She called Fan Yanqing in a low voice,

"Teacher Fan? You speak!"

What a god to leave at this time!

Fan Yanqing's face seemed to have stiffened into a piece of wood, with the upper and lower lips bumping against each other.

"Materials...are also imported."

The expressions of everyone present changed.

He looked at Fan Yanqing almost speechlessly.

This...isn't this a hooligan thing? !

Scientific hooligans!

Don’t even lose your face!

What things really belong to the Ning Group?

Gu Weimian narrowed his eyes and sighed,

"That's it..."

It’s not that China doesn’t have engines, it just doesn’t have engines for regional aircraft.

It’s not that China doesn’t have high-end materials, but there are too few, too few to make a large aircraft!

However, the Ning Group, which is praised by everyone as the hero of the aviation industry and even China's manufacturing industry, actually has neither.
