Everyone's eyes moved to the special black 'color' forward sweep wing model. [Search for the latest update.du8du8]

"Hahahaha!"

Burst into laughter.

"I said, Lao Yan, you're too joking!"

"That's it, even if you break the siege for your apprentice, don't use this as an excuse, are you old and confused."

"I'm going to laugh to death, if it's really designed by your apprentice, you'll almost be able to become a teacher, Lao Yan, you don't have a fever, I said everyone, isn't it, hey, your expression, isn't it funny?" Don't skip words.

There were few people who laughed aloud, but most of them had strange faces.

"You, you?!"

The person who laughed noticed that something was wrong, and many experts didn't seem to think what Lao Yan said was funny, but looked thoughtful.

"What Lao Yan said is true."

Finally someone spoke.

“？!”

"Maybe? Are you stupid too? "Don't skip words.

"This young man is a real pilot, not a professional designer of the bubble research institute."

The person who laughed widened his eyes and looked no.

"It's true! I testify that the units you are in do not involve aircraft design-related majors, of course, not in the 301, 601, 608 and 611 institutes and other research institutes such as aircraft design, radar research and fly-by-wire control systems, and many units have this drawing, and the designer is Professor Yan's apprentice. ”

"I also testify that the designer of this 'demon' is Captain Lin, hehe, everyone is not only all, but also jokingly called the drawings of this aircraft open source design drawings, I also participated in the beginning, I thought it was a work of practice, and later, many research institutes and experts were involved, I did not hide my secrets, everyone finally completed the drawings, which can be called a grand event of domestic technical cooperation, as long as there is enough equipment and related technology, it is not difficult to realize."

This "is not difficult", but it requires a large amount of financial and technical support for capacity cooperation, and some space alloy materials that are even unattainable in the world, even if the United States is not necessarily able to achieve it, and even if it is realized, it is impossible to find a qualified pilot who can control such a super weapon.

Perhaps this "demon" is just the dream of many aircraft design experts, and it is only a dream.

After all, this drawing, which contains a lot of innovation and technical imagination, is too precious, and of course, there are people who are not willing to accept the dream that only exists on paper, and there are some parts that are manufactured for experimental data use, and there are also for the accumulation of technology, and a simplified prototype is made for testing.

Those who had doubts before were already dumbfounded, thinking it was a joke, but it was still true.

So many old and young experts have unanimously testified that it is impossible to commit perjury en masse, and that science is the most intolerant of falsehoods.

"Don't talk to them, I'm about to fly the second one, Xiaolin, you go first!" Professor Yan is a strict guard for Lin Mo, and it is enough for these old guys to take a look at the precious apprentices.

Today, Professor Yan felt three pounds lighter, and he walked a lot more briskly.

Lin Mo saw that the mechanic in charge of the J-20 "Weilong" team was trotting all the way and beckoned to him, "There are still ten minutes, let's prepare first." ”

"Okay." Lin Mo nodded, and saluted the old-timers in the domestic flight design industry, and said that it will start in a while, I'll go first!"

"Stay safe!"

"It's up to you, lad."

Those experts no longer pestered Lin Mo, but put away their jokes and began to wait for the next good show.

The 17-ton J-20 "Weilong" is even lighter than the J-14 "Eagle Falcon".

However, the biggest difference in appearance is the air intake, J-14 adopts a diamond-shaped air intake design under the belly, while J-20 uses the same DSI air intake as the American fifth-generation fighter F-35, but the difference is that J-20 uses an adjustable DSI air intake, and an adjustable baffle is installed on the side of the air intake, which automatically changes the air intake volume according to the speed.

Almost all of the models tested in this test use the WS-15X vector propulsion engine, which is specially adapted for twin-engine fighters.

In addition, the J-20 is almost covered with phased array antennas (main wings, tail, nose and fuselage on multiple sides), with holographic perception and autonomous combat capabilities.

From the details, it reflects that the design of the J-20 aerodynamic layout has reached the extreme, and it is an air-superior heavy aircraft that is biased towards aerodynamic advantages.

It can be said that since the J-10, China has caught up with the level of fighters of the United States and Russia, and the J-14 and J-20 basically maintain the same "sexual" performance as the fourth and fifth generation aircraft of the United States and Russia, and even have local advantages.

The only defect may lie in the engine, which is a historical shortcoming, the yield rate is very low, has been plaguing the domestic aviation industry manufacturers, which even Lin Mo has a deep experience, often order a finished product, will scrap dozens of workpieces, directly resulting in a frighteningly high cost.

The cockpit "operation" control of the J-20 is more streamlined, the two spliced touch "touch" main screens realize the buttons, and the optical transmission "operation" system is adopted, and the optical fiber is used instead of wires, which is not only stronger and less susceptible to interference, but also small and saves space and weight.

Lin Mo's genuine "demonic" drawings use the optical transmission "operation" system, which can carry a larger amount of data.

Moreover, the expandable "sex" energy in the future can be greatly improved, which is also Lin Mo's compromise on the existing technology's inability to complete the drawings at one time, after all, this is just a dream model.

Through the gold-coated cockpit canopy, Lin Mo saw that everything on the ground was shrinking rapidly, because of the use of the same engine, the lift-off capacity J-20 and J-14 are basically not much different, but the main wing area is 6.76 square meters, and the cruising speed of sound and maximum speed of sound are relatively increased
