Chapter 13 gives the whole world a big surprise! Are you worthy of being a dog? (Please read and collect!)
I only saw this set of data displayed on the big screen PPT.
The original aircraft model similar to the F22 has become a brand new J-20 design sketch.
Not only the canard aerodynamic layout is used, but the materials used in the canard and other parts are highlighted.
【New ultra-high strength carbon fiber composite material】
Xu Qing was overjoyed: "High-strength carbon fiber composite material?? This thing is all made!?"
For the entire engine and fuel system project team, the most important concern in their hearts is the outdated AL-31F turbofan engine, followed by composite materials.
Why has the lift coefficient not been able to increase before? In addition to poor engine performance, even the composite materials used in various key parts are not up to standard.
It can only use titanium alloy and other materials that are much heavier in the same volume, which also leads to a further increase in weight and makes it more difficult to achieve the specified lift target.
"Old Song, this is no joke!" Xu Qing stared at Song Qinyi and asked nervously: "How strong is this high-strength carbon fiber composite material?"
They have made calculations before. If the strength of carbon fiber composite materials reaches the standard, if used on the J-20, the mass of the metal structure will be reduced by 31.5%, the mass of parts will be reduced by 61.5%, and the mass of fasteners will be reduced by 61.3%; composite vertical stabilizers It can reduce the mass by 32.24%!
In other words, if the J-20 with an empty weight of 17 tons uses about 30% carbon fiber composite materials, how much weight can be reduced?
Not only can the lift coefficient reach the standard, but the cruising range and bomb load can also be greatly improved. How significant is this?
"Don't worry, its tensile strength is expected to be 5.5Gpa, and its elastic modulus is 295Gpa." After Song Qinyi decisively reported a set of data, he said with finality: "The comprehensive performance can be compared to Toray's T800 strength scale carbon fiber composite material."< br>
Hear this.
"5.5Gpa tensile strength?? That's enough, that's enough!" Xu Qing froze on the spot, muttering to himself.
This is a carbon fiber composite material that meets the T800 strength specification. Even if it is used on the J-20, it will not be a problem at all.
One of his two major worries was solved so suddenly. Xu Qing felt like he was dreaming at this moment.
Who said that without Neon Toray’s high-strength composite carbon fiber, Daxia would never be able to build a fifth-generation stealth fighter?
Now, they have done it!
However, Xu Qing had not yet waited for his impassioned speech.
"Next, let's move on to the next technology." Song Qinyi seemed to give him no room to think as a brand new picture appeared.
"Hey, there's a brand new technology??" Everyone gasped.
What day is it today? The surprises came one after another. No wonder they heard the magpies chirping outside when they went out.
A set of data is listed on the PPT on the screen.
[High thrust-to-weight ratio binary vector turbofan engine technology. 】
[Maximum (military) thrust: 116KN. 】(≈11.8 tons)
[Afterburner thrust: 156KN. 】(≈15.9 tons)
[Push-to-weight ratio: 9.2. 】
In an instant, the entire conference room was silent.
Can this thing be made out? Are they dreaming?
And looking at this data, everyone suddenly felt more and more strange, even more and more familiar.
A binary vector engine with an afterburning thrust of 156KN? Even the military thrust has 116KN! ?
Why is this data so similar to the F119 engine on the F22 fighter jet? Even the thrust-to-weight ratio data are exactly the same!
However, these surprises and shocks are just the beginning.
【Nano Stealth Coating Technology】
[Integrated core processor platform technology for avionics systems.]
【Aviation flight control technology.】
One technology after another is displayed on PPT.
In this situation, several project leaders couldn't help but murmur in their hearts: 'Just now it was the aerodynamic layout of the F22 fighter jet, now it is the F22 engine... the second generation stealth coating technology...'
‘Did this old Song from BYD rob Yingjiang? ’
The data of each of these technologies can be said to be world-leading. The most outrageous thing is that all these technologies are comparable to the F22 fighter jet?
"This data, this data. The afterburner thrust is 156KN, hahahaha!" Xu Qing stood there, trembling a little, and started laughing!
On such an important occasion, it was absolutely impossible for Song Qinyi to joke with him.
This also means that the technology on these data is absolutely real and effective. Although he didn't know where these technologies came from, where did Song Qinyi obtain these engine technologies that were completely comparable to the F22's F119 in terms of data.
But he didn't care, he only knew that the J-20's engine was finally available.
Finally, there is no need to use the old AL-31F engine anymore. These engines are from the early 1970s, and they are seriously holding back the J-20.
All the project leaders present felt the same way, although they were a little confused.
But does it matter? Completely irrelevant!
Possessing the above technologies means that the J-20's performance in all aspects, including stealth performance, maneuverability, speed, etc., will be greatly improved. As long as they know this, it is enough for them.
"Everyone, with these new technologies, are you confident that the first demonstration aircraft will fly within half a year?" Song Qinyi stared at the crowd and asked a question with a smile on his face.
"At the same time, the prototype will be flown within one year."
The first flight verification aircraft in half a year? ?
Hearing this, Xu Qing slammed the table and stood up: "Old Song, as long as these technologies can be submitted, let alone within half a year."
"Give me four months, four months is enough to build the first dual-hole verification machine." There was perseverance in his eyes.
For a moment, the whole conference room was filled with echoes.
With the blessing of these heaven-defying technologies, their research and development progress will be greatly accelerated, and four months is not too difficult.
Even optimistic estimates suggest that the J-20 may enter the mass production and finalization stage today next year.
Hear this.
"Okay, I'll give you four months." Song Qinyi nodded.
Four months is just right, and the big day will soon be approaching.
Try to give the whole world a big one at that point in time!
Two days later.
Across the ocean, outside LLNL National Laboratory.
Lu Ze was looking at the surrounding environment with interest, admiring the lush scenery in the distance.
The laboratory is located in the Jinshan Bay Area, and next to it is the world-famous Silicon Valley, including Intel, Google, Apple and other technology giants, whose headquarters are set up in the small valley next to it.
This is also the Bay Area where people like Li Yijie yearn to work here all the time.
Unexpectedly, no matter how hard Li Yijie tried to attend Duke University's "social gathering" and integrate into their so-called group, he would not have the slightest chance to come here.
And Lu Ze, an isolated person, was deliberately transferred to this national laboratory.
However, he could only express his wish to die.
No matter how much these people lick Yingjiang, others won't take it seriously. I'm afraid they will only say one sentence to him: Are you worthy of being a dog?
only.
Lu Ze, standing at the gate, was thinking about another question at the moment.
"When entering the laboratory, what should I copy first?"
There are a lot of good things at LLNL National Laboratory, and he is a bit spoiled for choice.
Although those high-level technological items are very tempting, as long as they are copied, they will definitely reward a lot of achievement points in the future.
But Lu Ze couldn't help but want to give Neon a shot and turn it into a three-dimensional original.
Who told us to be kind-hearted, but we can’t let people indulge in the second principle!
