Many researchers present did not know Chen Nian's identity or what he could do, but the earliest experts involved in the evaluation, especially Lei Gang and Chen Guo, could sense Chen Nian's potential.
The moment he saw him raise his hand, Lei Gang immediately understood that this young man who had already brought him a huge surprise might have made a bigger breakthrough.
"Everyone, please be quiet for a moment."
"I have heard all your opinions. To sum up, there are only two voices."
"The first one thinks that we should be pragmatic and down-to-earth and understand one aspect thoroughly first."
"The second one is that we should dare to think and act boldly and challenge a goal that can completely change the status quo."
"In my opinion, both suggestions are correct and are rational judgments based on the situation we are facing now."
"But, personally, I prefer the second opinion."
"Why? Because we have already created Ti-6Al-4V titanium aluminum alloy material."
"Two weeks ago, this kind of lightweight, tough, high-temperature-resistant material was an elusive goal, but now, I can tell you with confidence that we can achieve this material in the short term. mass production!”
"This was a huge breakthrough, and the people who made it - people, they told me they could have more!"
“Among them, they include single crystal nickel-iron alloy, Alloy C flame-retardant titanium alloy, ceramic matrix composite TBC, and resin-based outer duct coating.”
"Of course, the establishment of a project should not be based on any guarantee, but I think we should at least try and give them a chance and give our 601 Institute a chance."
"This may cause a certain amount of resource consumption, but this consumption is within an acceptable range."
"So my suggestion is to upgrade Project No. 22, expand the boundaries of the project, and make building an airplane our main goal!"
As soon as he finished speaking, there was a roar of applause in the conference room.
"Okay! You have to have such a spirit! If you don't even dare to think about it, what the hell are you doing!"
"That's right! We've all been cowardly for so many years, it's time to let go and do something!"
"That's right! Damn it, what's the point of just blowing up a wind tunnel and building a model? In the end, it's just a contribution of some machine time to the system. If you want to do it, go big!"
"Isn't it just about building an engine? It's as if the Yankee's engine is amazing. Everyone knows the principle. At most, we can solve the problems one by one."
"I think so too, even if it takes ten years? Ten years to leave a name in history is better than one or two years to get nothing but a professional title!"
.......
Of course, in addition to these optimists, there are also rationalists who have expressed doubts about this.
Especially after Leigang announced the project budget.
The first phase investment is 200 million.
The estimated investment in the whole cycle is 5 billion.
What a big deal?
Do you think the people above are here to build airplanes?
But to make such a decision, it’s not enough to just rely on the things in your hand, right?
Could it be that a super strong materials science team emerged from some remote research institute?
Or is there a major breakthrough at 606 Institute?
Or maybe those underground workers lurking in the United States suddenly made some amazing progress...
But no matter which possibility is possible, it seems a bit unrealistic when I think about it.
Amidst the noisy discussion, Lu Yan asked:
"Mr. Lei, this is such a big project, are we sure about it?"
"We can't just do research and development with enthusiasm, right? What's the opinion of the 606 Institute? Can they solve the aviation development problem?"
"We're just talking about design. If the engine can't push the plane in the end, wouldn't it be in vain?"
"The progress of ws-10 is not going well now. Whether we can pass the assessment next year is a question. Are we pinning our hopes on this thing?"
Lei Gang shook his head and replied:
"The Turbofan 15 is not our target solution. Our target is the F119-PW-100."
"Are you kidding me?"
After the words fell, everyone was stunned on the spot.
Even the most optimistic Zhao Sui looked at Lei Gang in astonishment, with disbelief in his eyes.
The F119 engine is the most powerful small bypass ratio turbofan engine in the world today, with a maximum thrust of 19.5 tons, a thrust-to-weight ratio of 11.5, and a net weight of only 1,300 kilograms.
Since its first flight six years ago, the legend of this engine has been circulating in aerospace research institutions around the world.
Countless eyes stared at him closely, and countless people tried to decipher its secrets. However, its complex design principles, ultra-high processing accuracy, and unique manufacturing materials have discouraged many researchers.
In comparison, the Turbofan 10, which has been developed for more than 10 years, looks like a product that is behind the times!
After all, in the plan, the maximum thrust of the turbofan 10 is only 13 tons, and the thrust-to-weight ratio is only 7.8.
Although the difference is not big in numbers, it can be converted into actual performance, but it is not even half of the F119.
And this is already a representative of the highest level of China's aerospace industry.
Under such circumstances, where did Lei Gang get the confidence to actually say that the target was F119?
Lu Yan's face was full of doubts. He looked at Lei Gang constantly, waiting for his answer.
Lei Gang cleared his throat and unfolded the document on the table that was almost soaked with his sweat.
He held up the document and said:
"As everyone mentioned just now, there is actually nothing surprising about the design principle of the F119."
"What really hinders us from 'making' it is the craftsmanship and the materials."
"If these problems are solved, the engine problems will not only be solved, but at least the difficulty will be greatly reduced."
"And now, what I'm holding in my hand can solve one of the problems."
"Problems with turbofan blades."
Turbofan blades?
Lu Yan frowned.
This is indeed the most important issue in aviation development, and it is also one of the most difficult issues.
It is so difficult that even Russia cannot solve it. In the end, a multi-rotor structure was used to make up for the lack of power.
If this problem can be solved, it seems that just as Lei Gang said, the core problems of aviation development can be reduced by at least half.
But how to solve it?
Hollow blade? Perforated blade? TBC coating?
It can't be the blade material...the difficulty of this thing is not ordinary...
However, the moment this idea flashed through his mind, Lei Gang's voice also sounded at the same time:
"This is an industrial manufacturing method manual for single-crystal nickel-based high-temperature resistant alloys."
"We have asked experts from the Institute of Materials Science and Technology of the Chinese Academy of Physics to test it, and the performance is reliable."
There was silence in the venue, and everyone fell into a brief panic.
No one doubts the significance of this breakthrough, they just don’t know what attitude they should take to deal with it.
Lei Gang looked around and finally landed on Chen Nian.
Then, he said:
"Everyone, starting from today, starting from Project 22, a new era is coming."
