Although it is said that Zhaohui's super development is the same every month. Now his height has reached 1.5 meters, and the childishness on his face is much less, but in everyone's eyes, this person still feels like a junior high school student.

Many people in the venue were whispering.

"Chief Master Yang said that the magic change 99 was designed by him, and I believe it is true."

"It looks like a junior high school student, listen to what he says..."

"We now invite Comrade Zhaohui to speak to us, everyone is welcome," Chief Master Yang took the lead in applauding.

"Then I went straight to the point, and everyone saw the banner hanging on the wall, CJ Super J-20. This is a fifth-generation aircraft. It has stealth capabilities in all radar bands, supersonic cruise capabilities, over-the-horizon strike capabilities, super-maneuverable capabilities, and super datalink sharing capabilities. ”

When the people below heard these high-tech requirements, everyone's eyes lit up, and some of them opened their mouths in surprise and forgot to close them.

Zhaohui continued, "We want to start counting now and let it fly into the sky in fifty days!" ”

"Ahh Many people who were thundered subconsciously stood up.

Almost everyone thought that he might know about tanks, but not about airplanes at all. Not to mention fifty days, it is a miracle that it can be made in five years.

"I know what everybody is thinking. If we use the traditional way to build a fifth-generation stealth aircraft, let alone 50 days, let alone 5 years, it is already good to be able to build it in 10 years, or even 15 years. In today's world, even Sam Country does not have a fifth-generation stealth fighter, why do we dare to build a fifth-generation aircraft in 50 days? ”

Zhaohui scanned the entire venue with his eyes at this time. Then he said:

"My faith stems from three things. The first is that Chief Engineer Yang has been thinking about the fifth-generation aircraft in his heart for several years. He's even been doing his homework for several years. As we all know, China's military industry has always been a generation of equipment, a generation of test flights, a generation of research, and a generation of imagination. When Chief Engineer Yang designed the J-10, he had already started the work of the CJ20 in his heart. ”

"My second courage stems from some of our breakthroughs in scientific and technological prowess. Let me tell you a few good news, we now have 20 sets of five-axis machining centers, we now have the world's best lithography machine for the production of chips, we also have the world's best precision optical glass, we also have the world's best carbon fiber materials, we also cooperate with the power Tsar Marco Strange Company, we are equivalent to having the AL-31F turbofan engine. ”

"My third courage stems from our ability to innovate in science and technology. We will change the traditional manufacturing process. Change the traditional materials, change the traditional design concept, change the traditional way of cooperation, in short, we all stay if it is suitable, and we all change and innovate if it is not suitable. Then I want to ask everyone, are you interested, let's challenge this impossible together, make it possible, is it? ”

"Yes, yes!" Everyone's enthusiasm and morale were completely aroused.

Chief Engineer Yang and Zhaohui jointly made a report to the Central Military Commission and the Government Council on the CJ Super J-20 project. and submit a feasible project report. The Military Commission and the Government Council agreed and supported the project of the two of them.

If you fail, you should accumulate experience, if you succeed, it will be a historical leap, a milestone for Dragon Airlines, just like the magic change 99, using technology to form a generation gap with opponents, and become a milestone for the king of land warfare.

The Central Military Commission and the Government Affairs Yuan urgently transferred personnel, equipment, materials, technology, and funds to the whole country. Everything makes way for the CJ Super J-20 project, and the whole country will do great things!

KK and Chief Engineer Yang set the tone for the development of the CJ Super J-20.

First of all, the aerodynamic shape of the CJ Super J-20 will adopt a new design. The idea of canard wings, swept wings and double vertical tail designs similar to the J-10 is still adopted, but relatively large changes should be made in some parts.

Chief Engineer Yang suggested that the double vertical tail should be treated with an inclination angle, because the wind resistance will be reduced, and the maneuverability will be greatly improved. The inlet is then a clam-type intake...

After a day of argumentation and discussion, Zhaohui turned on the meditation study mode again in the evening. He deepened the line of thought he had discussed with Chief Master Yang during the day.

A kind of lifting body edge strip duck aerodynamic layout gradually appeared in Zhaohui's mind. This is based on a design that takes into account both supersonic cruise and subsonic high maneuverability, as well as stealth.

In order to achieve supersonic cruise and reduce wave resistance, this magic aircraft uses a wing with a large sweep angle, a small aspect ratio, a small relative thickness and a small area, and uses a large slenderness ratio fuselage to "knead" the lift body, side strips and canard layout into an aircraft, which can greatly improve the maximum lift coefficient and lift-to-drag ratio of the aircraft, thereby improving its maneuverability.

The length of the aircraft is 20.5, the height is 4.5, the width is 3.95, and the wing area is 78 square meters...

A set of transparent data, floating in Zhaohui's cranial neural network.

Zhaohui's eyes suddenly opened, and he hurried to the computer desk. He used a computer to remotely access the server in the computing center and began to restore the aerodynamic design of the aircraft obtained in a meditative study state.

Early the next morning, Zhaohui didn't have time to catch up on sleep and rest. Hurriedly found Mr. Yang and showed the printed CJ Super J-20 aerodynamic shape design to Mr. Yang.

"It's a perfect design, and that's what I wanted. Let's build a prototype and conduct wind tunnel tests and look at the actual test data. Chief Master Yang said excitedly.

"Yes, you have to build a prototype first. This time, though, I wanted to build this prototype with a completely new process. ”

"What new process? Don't you need to open a mold? Chief Master Yang asked.

"Master Yang, you're really right. We don't need to open the mold, we use 3D printing. ”

"Do you mean three-dimensional printing, directly printing the finished product, and then using a five-axis machining center for fine microprocessing?"

"Exactly."

"However, the world today has never heard of any country with 3D printing technology."

"Then let's take out the spirit of being the first crab eater, and we will design a set of independent innovation."

"It's a veritable hack. I support! Mr. Yang was also infected by Zhaohui's spirit of scientific and technological innovation.

In order to be in a hurry, Zhaohui decided to make the 3D printer first and give up the pursuit of miniaturization. To make a 3D printer, first of all, it is inseparable from industrial computers, especially computer chips. He commissioned Loongson to urgently process a small batch of 193-nanometer chips.

He also urgently transferred a batch of stepper motors and metal powder of 7075 aviation aluminum through the Commission of Science, Technology and Industry for National Defense.

Zhaohui led a group of engineers and machining personnel, and after almost 20 days of tinkering, a super-large 3G printer was finally built. The reason why it is said to be a super-large 3D printer is because the size of this printer is indeed a little bigger.

The height of the printer reaches 12,200 mm, the length reaches 4,500 mm, the width reaches 3,700 mm, and the moving range of the self-propelled table reaches 42,000 mm.

This 3D printer can print workpieces up to 38,000 mm in length and 9,800 meters in diameter.

In order to improve the printing efficiency, the 3D printer is set up with 4 sets of printing printheads. Simultaneous printing of metal and non-metallic industrial resin materials is allowed.

"My good man, I can be regarded as a teacher of what it means to work and do a good job, and I must first sharpen my tools. No wonder everyone says you're the strongest brain in the Dragon Kingdom. Chief Yang said after seeing this super 3D printer.

"The advantage of 3D printing is that it skips the two constraints of traditional molds and forging. Industrialized flexible manufacturing has been realized. Workpieces of any shape can be printed according to the construction drawings, and the production quantity can also be controlled arbitrarily. The benefits of 3D printing are high efficiency and low cost! Zhaohui explained.

With the ultra-large 3D printer, Zhaohui and Chief Engineer Yang began to print and produce the prototype workpiece of the CJ Super J-20.

After only 72 hours, all the workpieces of a prototype of the CJ Super J-20 were printed.

The printed workpiece is then erected on a five-axis digital machining center to begin to refine the surface of the workpiece.

After another 48 hours, the cutting and grinding of the CJ Super J-20 workpiece was completed.

Some of the processed workpieces are treated with a graphene coating process for 72 hours. and the surface workpiece of the body for the coating of graphene nano stealth material.

It took another six days to assemble the engine, avionics system, and fire control weapon system. Finally, a prototype of the CJ Super J-20 has been standing in front of everyone.

"It's beautiful, it feels very magical, a bit like an alien fighter."

"I'm really looking forward to it getting good grades!"

Chengfei organized personnel to pull this prototype from Rongcheng to Mianyang City, where it underwent a big test known as the first wind tunnel group laboratory in Asia.

The CJ Super J-20 will complete wind tunnel tests such as supersonic wind tunnel, shock wave wind tunnel, and high temperature and high cold temperature here.

After 48 hours of comprehensive testing of various wind tunnel groups, the CJ Super J-20's aerodynamic layout experimental data achieved excellent results.

"We're finally taking the first steps toward success." When Chief Engineer Yang read the test data of the CJ Super J-20 Wind Tunnel Group, he hugged Zhaohui excitedly.

From the first day of the project, various preparations took 10 days, 20 days of 3D printer manufacturing, 3 days of workpiece printing, 2 days of workpiece CNC machining, 3 days of body graphene nano stealth film processing, 6 days of engine, avionics, fire control system installation, plus 2 days of aerodynamic shape wind tunnel test, the first prototype from scratch, a total of 46 days.

This CJ Super J-20 prototype, with a gray-black paint all over, twin engines and two vertical tails, swept wings and a small duck wing aerodynamic layout, makes people feel that this is a great work of art.

Completed the wind tunnel experiment, which was the first test of the CJ Super J-20 test.

Next, there are more to start waiting for CJ Super J-20 to complete.

Go to you, CJ Super J-20 of Dragon Country!
