Chapter 2033 Heroes of China’s Aviation Industry
The explanation principle is relatively complicated, but what ordinary people can intuitively understand is:
Engines with large bypass ratios have lower fuel consumption, better propulsion efficiency, higher economic performance, and stronger stability than engines with small bypass ratios.
Of course, the manufacturing requirements are also higher. For example, the fan blades of the former are at least one meter long, while the latter only need about 0.3-0.4 meters.
Taking a very high-end engine as an example:
The sun never sets in the engine produced by Rolls-Royce for the A380. The maximum temperature inside the engine reaches half of the surface of the sun!
The pressure inside the engine reached 50 atmospheres!
The movement speed of the turbine blade tip reaches 2000 km/h, and its blade is more than 3 meters long…
In short…these four highs and two lows are simply a curse for manufacturing large civilian aircraft engines.
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 these things well.
But 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, there is also the material and process of the engine, which is also a major difficulty.”
Materials science is to some extent the cornerstone of the country’s manufacturing industry.
It also limits the development of a country’s manufacturing industry.
Don’t talk about big ones.
Let’s just say simple concrete.
In this world before she came back.
In 2018, China’s concrete was still not as good as Yamato’s.
At a time when China had a large amount of steel and even had 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, it is impossible to conquer some high-end parts.
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 sparkling eyes, he looked like a simple Chinese, admiring him and thanking him.
Fan Yanqing’s throat seemed to be blocked.
The corners of Ning Yuetong’s lips that had just been raised were forced back when she saw Fan Yanqing’s face.
She called Fan Yanqing in a low voice,
“Teacher Fan? You speak!”
At this time, what kind of person are you doing?
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.
Looking at Fan Yanqing almost speechlessly.
This…isn’t this a hooligan? !
Scientific hooliganism!
Don’t even think about it!
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!
The Ning Group, which is praised by everyone as the hero of the aviation industry and even China’s manufacturing industry, actually has neither.
