The explanation principle is relatively complicated, but what ordinary people can understand intuitively is:
Compared with engines with small bypass ratio, engines with large bypass ratio have lower fuel consumption, better propulsion efficiency, higher economic performance and greater stability.
Of course, the corresponding requirement is: 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.
Take a very high-end engine as an example:
The engine produced by Rolls-Royce for the A380 has a maximum internal temperature that reaches half the surface of the sun!
The pressure inside the engine reaches 50 atmospheres!
The tip of the turbine blade moves at a speed of 2,000 kilometers per hour, and its blade is more than 3 meters long...
In short... these four highs and two lows are simply a tight shackle for manufacturing engines for large civilian aircraft.
And because of this, the aviation manufacturing industry generally represents a country's manufacturing level.
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 cutting-edge scientific research figures.
Everyone knows all about this.
But because they know the situation clearly but are unable to change it, this sense of urgency and mission makes everyone more depressed and silent.
Gu Weimian nodded gently.
"In addition to the above problems, the material and process of the engine are also a major difficulty."
Materials science is, to a certain extent, the cornerstone of the country's manufacturing industry.
It also restricts the development of a country's manufacturing industry.
Not to mention the big ones.
Just say simple concrete.
In this world before she returns.
In 2018, China's concrete was still inferior to that of Yamato.
However, China, which had abundant steel and even excess steel production capacity, did not have the best special steel and needed to import large quantities of it.
Without good enough materials, it would be impossible to tackle some high-precision parts.
For example: how to withstand the horrifically high temperatures of regional jet engines without melting the entire barrel wall.
How can we ensure that the cylinder wall will not shatter or deform under a pressure of 50 atmospheres?
She looked at Fan Yanqing,
"Teacher Fan, you are a true master. You have solved major problems and difficulties for China Airlines, and finally fired the first shot for China Airlines."
She stood in front of the airplane model with a sincere and enthusiastic attitude.
His eyes sparkled, and he looked like a simple Chinese man who admired and was grateful to him.
Fan Yanqing's throat seemed to be blocked.
Ning Yuetong's lips, which had just curled up, were forced back down when she saw Fan Yanqing's face.
She called out to Fan Yanqing in a low voice,
"Teacher Fan? Say something!"
At a time like this, what kind of god is walking?
Fan Yanqing's face seemed to be as stiff as a piece of wood, with the upper and lower lips bumping against each other stiffly.
“The materials… are also imported.”
Everyone present changed their expressions.
He looked at Fan Yanqing almost speechlessly.
This... isn't this just being a hooligan?!
Scientific hooliganism!
Don’t you care about your shame anymore!
Is there anything that really belongs 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 they are too few, too few to make a large airplane!
However, the Ning Group, which is hailed by everyone as a hero in the aviation industry and even in China's manufacturing industry, actually has neither.
