Many of the researchers present did not know Chen Nian's identity or what he could do, but the earliest experts who participated in the evaluation, especially Lei Gang and Chen Guo, could feel 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, just be quiet."

"I've heard all of your opinions. In summary, there are nothing more than two voices."

"The first one is that we should be pragmatic and down-to-earth, and first understand one aspect of the content."

"The second is that we should dare to think and do, to challenge a goal that can completely change the status quo."

"In my opinion, neither of these two suggestions is wrong. They are both rational judgments based on the situation we are facing now."

"However, personally, I would lean more towards a second opinion."

"Why? Because we have created Ti-6Al-4V titanium-aluminum alloy material."

"Two weeks ago, this lightweight, tough, high-temperature-resistant material was still an elusive goal, but now, I can tell you with a pat on the chest that in the short term in the future, we can achieve this kind of material." mass production!"

"This is a huge breakthrough, and the people who made it -- people, they told me they could do more!"

"Among them, it includes single crystal nickel-iron alloy, Alloy C flame-retardant titanium alloy, ceramic matrix composite TBC, and resin-based ductwork coating."

"Of course, the establishment of a project should not be based on any promises, but I think we should at least try to give them a chance, and give us a chance at 601."

"This may cause a certain resource consumption, but this consumption is within an acceptable range."

"So my suggestion is to upgrade the No. 22 project, expand the project boundary, and regard the creation of aircraft as our main goal!"

After the voice fell, there was a burst of applause in the conference room.

"Okay! You have to have such a heart! If you don't even dare to think about it, then what a fart!"

"That's right! We've been useless for so many years, it's time to let go and do something!"

"That's right! What's the point of just blowing up a wind tunnel and building a model? In the end, it's just contributing a little time to the system. If you want to do it, just make it bigger!"

"Isn't it just building an engine? It's as if the engine of the Yankees is amazing. Everyone understands the principle. It's a big deal to solve the problems one by one."

"I think so too, even if it takes ten years? It's better to leave a name in history for ten years than to get a mixed job title with a result full of water in one or two years!"

Of course, in addition to these optimists, there are also rationalists who have expressed doubts about this.

Especially after Lei Gang announced the project budget.

The first phase investment is 200 million.

The estimated investment in the whole cycle is 5 billion.

What big deal?

Dare to feel that the above is rushing to build airplanes?

But to make such a decision, the things in hand are not enough, right?

Could it be that from some corner of the research institute, a super strong material science team sprang out?

Or is there a major breakthrough in the 606 Institute?

Or those underground workers lurking in the United States suddenly made some amazing progress

But no matter which possibility, it feels a bit unrealistic to think about it.

Amidst the noisy discussions, Lu Yan asked:

"Mr. Lei, are we sure about such a big project?"

"We can't just do R\u0026D with enthusiasm, right? What's the opinion of Institute 606? Can they solve the problem of Aviation Development?"

"We only talk about design. If the engine can't push the plane in the end, isn't it a waste of time?"

"The progress of WS-10 is not going well now. Whether we can pass the assessment next year is a question. We are not pinning our hopes on this thing, are we?"

Lei Gang shook his head and replied:

"Turbofan 15 is not our target program, our target is F119-PW-100."

"Are you kidding me?"

After the voice fell, everyone froze in place.

Even the most optimistic Zhao Sui looked at Lei Gang in astonishment, his eyes full of disbelief.

The F119 engine is the strongest 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 1300 kg.

Since the first flight of the aircraft six years ago, the legend of this engine has been circulating in aviation research institutions around the world.

Countless eyes stared at him closely, and countless people tried to crack its mystery, but its complex design principles, ultra-high processing precision, and unique manufacturing materials have discouraged many researchers.

In comparison, Turbofan 10, which has been in research and development for more than 10 years, looks like a product of an era behind it!

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 terms of numbers, it can be converted into actual performance, but it is not even half of the F119.

And this is already the representative of the highest level of Huaxia Aviation Development Industry.

Under such circumstances, where did Lei Gang get the confidence to say that the target is F119?

Lu Yan was full of doubts, and he looked at Lei Gang without blinking, waiting for his answer.

Lei Gang cleared his throat, and unfolded the document on the table that was almost soaked in his sweat.

He held up the document and said:

"As you mentioned just now, the design principle of F119 is not surprising."

"What really hinders us from 'making it' is the process and the material."

"After solving these problems, the engine problem will be solved, at least the difficulty will be greatly reduced."

"And now, what I hold in my hand can just solve one of the problems."

"Turbofan blade problem."

Turbofan blades?

Lu Yan frowned.

This is indeed the most important problem in aviation development, and it is also one of the most difficult problems.

Its difficulty is so high that Russia can't solve it. In the end, a multi-rotor structure is used to make up for the shortcoming of insufficient power.

If this problem can be solved, it seems that, as Lei Gang said, the core problem of aviation development can be reduced by at least half.

But how to solve it?

Hollow blade? Perforated blades? TBC coating?

It can't be the blade material, right? The difficulty of this thing is not ordinary.

However, the moment this thought flashed through his mind, Lei Gang's voice also sounded at the same time:

"This is a handbook of industrial preparation methods for single crystal nickel-based superalloys."

"We have invited experts from the Institute of Materials Science and Technology of the Chinese Academy of Sciences to test it, and the performance is reliable."

The venue was silent, 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 for a week, and finally his eyes fell on Chen Nian.

Then he opened his mouth and said:

"Everyone, starting from today, starting from the 22nd project, a brand new era is coming."
