In the Tianyu Xinghai Research Department, Leng Fangguo met Ma Tian, who was leading people to study.

Seeing Ma Tian's figure, Leng Fangguo's first impression was that he was young, still young, and an indescribable temperament, not the domineering he expected when he came, but... On the contrary, it is more like confidence and elegance, but it is a little different.

"Hello, Leng Lao, I'm sorry, I just ran into a question of interest, so I didn't pick you up!" Looking at the old but tall figure next to Ji Leiming, Ma Tian also quickly realized that this was Leng Fangguo, with a smile on his face, he took the initiative to say hello to Leng Fangguo and explained.

Leng Fangguo is at the same level as Wang Chenbo, and he deserves his respect.

"It's okay, Ma Tian, don't be so polite!" Leng Fangguo also smiled when he looked at Ma Tian, he didn't mind this bit of courtesy or respect.

And for scientific researchers, there is really no need to talk so much, there are many scientists with more personality than Ma Tian.

The five people who were traveling behind Leng Fangguo also looked at Ma Tian, and their thoughts were also different.

"How young!"

"Niu Bi, single-handedly created Tianyu Xinghai, what a genius!"

……

And Su Xihua and the others behind Ma Tian also looked at Leng Fangguo and his party, they may have to work together for a while in the future, they are still a little curious about each other, and they don't know what the level of the research institute is.

Ma Tian and Leng Fangguo continued to greet each other for a few words, and began to take them to visit the office area, which was regarded as the friendship of the landlord.

After the visit, Leng Fangguo was also a capable person, and he said directly to Ma Tian: "Ma Tian, let's talk about this work directly, we want to know what you are planning?" ”

After speaking, Leng Fangguo also looked at Ma Tian's facial expression, he hoped that Ma Tian was not a fool, but really had the grasp and idea of studying the sixth-generation aircraft.

Ma Tian's face was calm and nodded: "Come with me, Leng Lao!" ”

After speaking, he took Leng Fangguo and the others to a special office, where Ye Yuyan, who was a modeler, was wearing big black-framed glasses and typing on the computer.

There are also a lot of people in the office, who are either serious about their work or talking softly.

Seeing Ma Tian's arrival, he stopped his work and greeted Ma Tian: "Mr. Ma!" ”

"Ye Yuyan, project our White Emperor design on the screen." Ma Tian said to Ye Yuyan.

Ye Yuyan nodded, then tapped the keyboard a few times, and after a while, the 200-inch screen in front began to project the design of the "White Emperor" fighter developed this time.

Immediately, Leng Fangguo and the others widened their eyes, and looked directly at the figure of the White Emperor on the screen, as well as the various modeling parameters on it.

"The length of the aircraft is 25.8 meters, the wingspan is 14.2 meters, the empty weight is 24.5 tons, the standard mission weight is 48 tons, and the maximum take-off weight is 54 tons."

"The cruising speed is Mach 2.6, and the maximum speed is Mach 4.8 (extra-atmospheric combat is not supported for the time being)."

"Variable wing, outwardly inclined twin vertical tails, controllable contraction, maximum contraction wingspan of 12.6 meters."

……

"Hiss-" Looking at the concept map of the White Emperor fighter, Leng Fangguo took a deep breath, not to mention anything else, is the atmospheric velocity of Mach 4.8 real?

You must know that the fastest known MiG-25 "Flying Fox" fighter/reconnaissance aircraft can reach a maximum flight speed of Mach 3.2.

However, at that time, the MiG-25 "Flying Fox" reconnaissance plane was able to fly at this speed mainly to escape for its life, and when it landed, all two of its engines had been scrapped.

The five people behind Leng Fangguo also didn't believe it, after all, they had been researching, and they were professionals.

Hong Huan, who was in charge of the power system, asked on the spot: "Ma Tian, did you design your power system by yourself?" Can it really support Mach 4.8 speeds? ”

Ma Tian glanced at him and replied: "The power system must have been designed by himself, and the speed of Mach 4.8 is the speed calculated by our modeling. ”

Listening to Ma Tian say that the theory could reach this speed, Hong Huan didn't continue to ask questions, thinking in his heart that it was just theoretical data as he guessed.

When it is really made, it is estimated that there will be a question mark over whether it can take off.

However, the matter has not yet been decided, Hong Huan naturally will not be stupid to ridicule or question at this time, they are all adults, give some face.

Leng Fangguo glanced at Hong Huan on his side, then looked at Ma Tian and said, "You guys have made the model diagram, the efficiency is really fast enough!" ”

Although Leng Fangguo also felt that Ma Tian's model had a kind of exaggerated performance, he still praised a few words, after all, Ma Tian is a young man, and it is normal to be a little happy!

"Well, it's okay!" Ma Tian was expressionless and didn't say much.

He didn't notice the disbelief of Leng Fangguo and the others, he only thought that Leng Fangguo was sincerely praising their side.

"Ma Tian, tell us about your design concept and basis!" Leng Fangguo opened his mouth and said, the birth of a design drawing must have a basis.

From this basis, it can also be seen that the level of the designer, Leng Fangguo wants to break through from this aspect, to teach Ma Tian to realize the difficulty of fighter design.

You can't just be imaginative, you have to consider the impact of all aspects step by step, and calculate it step by step.

Ma Tian nodded and began to state:

"The 'White Emperor' fighter I designed must have essentially followed the design concept of the sixth-generation aircraft. First of all, in terms of improving speed, the speed of the sixth-generation aircraft must be comprehensively crushed by the fifth-generation aircraft.

Considering the limitations of the pilot factor on the fighter, our fighter adopts the form of unmanned control! ”

"Wait a minute, is it the same remote control as the T-X1 multi-purpose tank?" Leng Fangguo interjected and asked.

"Well, yes, exactly!"

"But will that be interfered with electronically? You must know that the fighter plane can fly thousands of kilometers away casually, can it have such a long remote control distance? Leng Fangguo raised his own questions, including Hong Huan and Diao Yuxuan behind him, their eyes widened, and their brows couldn't help frowning.

"Yes, because we have a technology that can be controlled remotely and effectively prevent interference!" Ma Tian's face remained unchanged and he spoke eloquently.

This remote control technology was naturally developed by him with the physics knowledge of Lv4 recently, and Ma Tian named him - remote electromagnetic wave interference technology.

As the name suggests, this is a communication technology that uses electromagnetic waves to communicate remotely, which is not a normal electromagnetic wave communication, but a duplex technology used in a specific frequency band.

Somewhat like the reliable communication channel established by the four-way handshake in the Internet, this is a reliable communication channel established in a specific frequency band using special electromagnetic interference.

Without a specific band of electromagnetic wave keys, it is generally difficult to be cracked and interfere with the accuracy of communication, and specific interference means that it is difficult to be interfered with.

Unless a special metal cover can cover the "White Emperor" fighter, there is absolutely no possibility of complete interference.

Leng Fangguo and others said they were unclear.

"You go on!"

"Since it is in the form of unmanned control, then we can use the aerodynamic design to minimize the drag coefficient without interference such as the cockpit, which can also be seen from the overall fuselage design!"

Ma Tian continued: "In order to increase flexibility, we also specially designed this variable wing, in cruise mode, the wing will be tilted outward, so that you can quickly control difficult maneuvers such as aircraft flipping.

Once speed is required, the wing lies flat and the entire fuselage becomes a manifold, minimizing fuselage drag ......"

Ma Tian is still introducing, the concept map of the White Emperor is basically designed according to his concept, and what he introduced is also hand-made without any pause.

Leng Fangguo and the others also listened to it, the more they didn't feel wrong, how could Ma Tian say it was very reasonable, could this "White Emperor" concept map really be designed?

"Overall, the design concept is like this, of course, there are some details that I won't go into detail, because it is estimated that it will be introduced until dark when you introduce it carefully!" After speaking, Ma Tian looked at Leng Fangguo and the others who were stunned.

After thinking about it, he learned from the polite plot in the TV series he watched: "Leng Lao, do you have any high opinions?" ”

"Uh..."Leng Fangguo finally came back to his senses, "Well, we haven't understood this in detail, let's wait until we take a closer look at the conceptual design drawing!" ”

Leng Fangguo is still confused, Ma Tian can still understand a little bit in the front, and he will listen to the book of heaven a little bit in the back.

What is the optimal solution formula for the lift coefficient of the angle of attack range, the formula for the rate of climb and the unit residual power, etc., he can understand the formula, but he can't understand it.

"Okay, then I'll show you the conceptual design first, if you don't understand anything, you can ask our engineers here, Su Xihua, you are responsible for the whole process!" Ma Tian said to Su Xihua behind him.

From the very beginning, Ma Tian didn't expect Leng Fangguo and them to bring any surprises, politeness should be enough in the afternoon, and it would be handed over to Su Xihua later.

In the final analysis, this research has to rely on his hanging wall to open the research, and he doesn't have so much heart to deal with those people's sophistication, as long as he studies the fighter plane, he has to shut up about everything.

handed over Leng Fangguo and the others to Su Xihua for arrangement, Ma Tian also returned to his original position and continued to take the engineer to overcome the problem of the flying wing.

This variable wing, don't look at it as just a simple deformation, the difficulty involved is not ordinarily large.

Don't compare it to an ordinary toy, you have to think about it, this is a deformation at a speed of almost Mach 3, how big the wind speed is at Mach 3, you can refer to the speed of 80 km/h without a helmet to ride a motorcycle.

Mach 3 was almost 80 times faster than 46 km/h, reaching 3,672 km/h.

Therefore, the material requirements for this variable wing are very strict, and various factors in the deformation must be fully considered, including airflow, temperature, damage, etc.

This needs to be closely calculated and simulated before it can really be built, otherwise a little deviation is an aviation accident.

"What are the results of the simulation? Still doesn't work? Ma Tian asked Ye Yuyan and other engineers who were simulating.

Engineer Xia Qinglin on the side shook his head and said: "Mr. Ma, the simulation can't achieve the results you want, and it can't be synthesized with the latest carbon fiber materials. ”

"What about hydrocarbon-nitrogen-2 synthetic fibers?" Ma Tian asked, hydrocarbon and nitrogen 2 synthetic fibers are the new ceramic materials he uses to make the fastest bicycles, and later made body armor.

"No, the hardness of hydrocarbon and nitrogen 2 synthetic fibers is enough, and the toughness and melting point may be a bit dangerous!"

The melting point of hydrocarbon and nitrogen 2 synthetic fibers is only more than 400 degrees, and this temperature can only barely meet the thermal barrier demand brought by Mach 5.

Ma Tian fell into deep thought after hearing this, and it seemed that he still couldn't get around the new material, and he had to find a material with strong toughness, high hardness, and high melting point.

Thinking of this, Ma Tian simply returned to his laboratory and started a new round of retreat, seeking more suitable materials.

And Leng Fangguo and others have been adapting to the environment for a few days, and they have begun to join the research work of Su Xihua and others.

"No, your power system is a little wrong, your engine can have such a big performance?" Hong Huan, who has been dealing with the power system all year round, was shocked, he looked at the engine parameters designed by Tianyu Xinghai and was frightened, is this really the engine parameters manufactured by the domestic production capacity?

250 knewn, what are you kidding?

"Hong Gong, our engine can really reach this level!" Su Xihua nodded expressionlessly, glanced at Hong Huan, and didn't know why he came to question the strength of Tianyu Xinghai.

The engine has long been broken by Ma Tian, just look at the engine of the Tiangong Giant God excavator, there is no powerful engine, can drive the Tiangong Giant God weighing more than 200 tons?

"Huh?" Hong Huan looked confused, when can a domestic engine be so strong? How did he not know?

I forgot to mention that the thrust of the top engine of the fifth-generation aircraft is about 180 kN, and the engine parameters of the sixth-generation aircraft newly researched by Eagle Sauce are only expected to be 200 kN.

That's it, Eagle Sauce has been on the show for at least 2 years, and it is said that it must be the first country in the world to come up with a sixth-generation engine engine, and the engine with a thrust of 200 kN will lead the world.

Su Xihua glanced at Hong Huan and asked uncertainly, "Hong Gong, have you been studying before and haven't paid attention to things outside?" ”

"It's not that I haven't paid attention, I don't pay much attention!" Hong Huan replied.

That's reasonable, Su Xihua nodded and didn't care, and began to talk about some things about Tianyu Xinghai:

"As early as 1 year ago, the engines developed by our Tianyu Xinghai were applied to automobiles, including Tianming Automobile and excavators in cooperation with Shanyi Heavy Industry, all of which were self-developed engines developed by our Tianyu Xinghai!

Moreover, our Tianming No. 3, in the 100-meter straight race, directly won the Toyota Supra sports car of the island country, which directly proved that our engine is ahead of foreign ......"

Hong Huan was stunned, and listened to Su Xihua with his mouth wide open, at this time he urgently needed to calm down, why did he study in the research institute for a few years, and the outside world was a little different from what he imagined.

He had the impression that foreign engines were stronger and more stable.
