Chapter 202 Is this a drone or a bomber?
"Combined with the previous failure cases of the institute, the positioning of this domestic drone must be determined first."

"As I said, if we are going to do something, we have to do the most advanced one."

In the morning at the School of Mathematical Sciences of Qinghua University, Xu Yuan was sitting at his desk in a professor's office. He seemed to be concentrating on thinking about the positioning of the drone.

From the very beginning when he initiated the project of domestic stealth fighter, his view was to make it the best.

Otherwise, it will take a short time to upgrade, which is a waste of resources in all aspects.

Take the J-20, which has gradually entered the production and service stage. Its excellent performance alone will allow it to maintain its leading position in the next two or three decades. In addition, with breakthroughs in technologies such as radar materials, the performance of domestically-produced stealth fighters will be further improved.

It is definitely not an easy task for other countries to catch up.

Therefore, in the research and development of domestic drones, we must also aim to develop the most advanced ones in the world.

As the ideas in his mind became clearer, Xu Yuan also determined the positioning of this domestically produced drone.

I picked up a pen and wrote a few lines.

Long voyage.

Remount.

Multipurpose.

From then on, Xu Yuan began to design the appearance layout of this clearly positioned drone based on his professional knowledge and memory.

No matter what kind of aircraft, the aerodynamic layout and shape are very critical.

Reasonable design can make the aircraft have a longer range and have good coping performance when facing complex environments.

Otherwise, it is no different from a failed product.

The drone previously developed by Jincheng Aircraft Design Institute was abandoned due to various problems.

He was able to complete the appearance design of the domestic stealth fighter, so it would naturally be no problem for him to come up with the appearance of a drone.

In a blink of an eye, a few months passed, and in December, Xu Yuan's appearance design plan was finally basically completed.

For this new type of drone, he chose to adopt a normal aerodynamic layout.

High aspect ratio mid-wing.

The wings are equipped with flaps and ailerons, and adopt a front three-point landing gear with retraction and braking functions.

In addition, he also adopted a special layout of wingtip winglets, which can reduce the induced drag at the wingtips of the aircraft, thereby increasing the aircraft's flight stability and maximum range.

You should know that this drone is designed for long-range flight, so it will naturally face complex and changeable climatic environments.

The use of winglets can improve the performance of an aircraft.

It can be said that Xu Yuan is quite satisfied with the aerodynamic layout and appearance design he completed.

Even the expected values ​​of the aircraft were given in the proposal.

Basically, as long as it can be successfully developed and passed on, it will definitely be able to sit on the throne of the world's most advanced drone.

In addition, he also planned the concept of the UAV system, which is composed of a UAV platform and mission payload, as well as a ground control station and an integrated support system.

Ensure the mission execution of the drone to the greatest extent possible.

In his vision, in the future, even drones of different models and functions can be connected to each other to form a matrix with the help of this system, and even use artificial intelligence to analyze and judge on their own to complete tasks.

It was precisely because of the addition of these contents to the plan that it took three or four months to complete the plan.

-

Monday, January 2008, 12.

Xu Yuan, who was working in the professor's office, was suddenly interrupted by the ringing of a cell phone.

Hearing the sound, he immediately took out his cell phone, turned off the alarm, and then got up to pack his things.

"It's almost time to go to the airport to pick someone up."

Due to the outstanding results achieved by the domestic stealth fighter project this year, the Aviation Industry Corporation of China chose to hold a summary meeting in advance.

Personnel from major aircraft research institutes and other subordinate units must go to the Yanjing headquarters to attend the conference.

As a researcher at the Jincheng Aircraft Design Institute, Xu Yuan is now in Yanjing, so he must go to the airport in person to pick him up.

Then we will go to the group headquarters together to attend the meeting tomorrow.

He simply packed up the things on his desk and hurriedly left the office for Yanjing International Airport.

Since he had already arranged a business vehicle in advance, there was no need to rush.

Speaking of which, during this period of time, while he was designing the drone's appearance, he was also busy with other things.

Not only was he invited to host this year's Olympic Mathematics Competition, he also gave several open classes in school.

The main reason was that he was not currently researching any mathematics topics, and given the strong demands from students in the academy, it would be unreasonable not to give open classes.

However, the content of his open class this time was different from the previous ones. The content he taught in class was relatively advanced, and at least one had to be a mathematics graduate student to understand the course content.

This caused great regret among the undergraduate students in the college.

Some stubborn people grabbed the spots, but when they got to the classroom they realized they couldn't understand anything at all.

Of course, he had no choice but to do so. After all, if he wanted to encourage everyone to write excellent mathematics papers and submit them to the Journal of Mathematics, the main force was still mathematics graduate students and doctoral students. Xu Yuan was undoubtedly familiar with Yanjing International Airport, and it didn't take him long to pick up everyone from the institute.

In addition to acquaintances such as Liang Zhanjun, Shen Yamin and Zhao Yuefeng, it also includes the director of the institute, Jia Yueguang.

After all, Song Wencong has officially retired and has not yet attended this summary meeting. According to his qualifications, only Jia Yueguang is the most suitable person to serve as the current director of the institute.

Although he was shorter than Song Wencong, he looked more energetic because of his younger age.

Although Xu Yuan was not very familiar with the other party, he still took the initiative to greet the other party after meeting.

"Hello, Director Jia."

Hearing this, Jia Yueguang showed no airs at all. He immediately shook Xu Yuan's hand and said with a smile on his face:
"Xiao Xu, I am really sorry to trouble you. Mr. Song asked me to fully cooperate with your work."

When Xu Yuan heard this, he felt much more relieved. After all, having a leader who is easy to get along with can make the project go more smoothly.

Next, Xu Yuan chatted with Shen Yamin, Liang Zhanjun and others, briefly asked about the formation of the project team, and then sent them to the hotel where they were staying.

It is worth mentioning that the choice of hotel was arranged by Aviation Industry Corporation of China.

Personnel from Fengtian Xijing and other research institutes will also be accommodated in the hotel at that time.

But perhaps because of the flight delay, the personnel from Jincheng arrived relatively earlier.

After checking in and arriving at the room, Liang Zhanjun couldn't resist his curiosity and asked Xu Yuan about the progress of the drone design plan.

"Has the design plan for our drone project been finalized?"

After asking, he looked at Xu Yuan expectantly, and Zhao Yuefeng next to him made the same move.

After Liang Zhanjun asked about the progress, he was not urging Xu Yuan, but he was mainly impatient.

At present, the entire project team has been formed, and he is also leading the analysis of the institute's previous drone projects, both to find out the reasons for the project's failure and to allow everyone to get used to each other.

It can be said that we are now waiting for Xu Yuan's aerodynamic layout and appearance plan, and then we can officially start research and development immediately.

He was also worried that Xu Yuan, who was responsible for the appearance design himself, might be delayed due to the heavy workload.

As project members, they should definitely help.

When Xu Yuan heard Liang Zhanjun's question, he didn't think too much about it. With a smile on his lips, an expression of understanding quickly appeared on his face, and then he directly answered the other party.

"I know you can't wait, so let's take a look first."

After saying that, he casually opened the backpack he was carrying and took out the laptop computer from it.

At this time, Liang Zhanjun asked in surprise: "Have you already completed the aerodynamic layout design?"

"Professor Xu's efficiency is amazing." Zhao Yuefeng next to him also exclaimed.

Even Shen Yamin and Director Jia Yueguang, who were still here, suddenly became interested.

He stared at Xu Yuan's computer with burning eyes.

They all knew Xu Yuan's strength in fluid mechanics and aerodynamics. The fact that he was able to design the complex and innovative canard aerodynamic layout of a stealth fighter already demonstrated his level in this area.

In this situation, what exactly will the drone, which the research institute has high hopes for and is said to be the most advanced drone in the world in the future, look like?

It's naturally exciting.

Xu Yuan raised his eyes and took in the expressions of several people. He just smiled and didn't say much.

But it opens the computer much faster.

Then he put the computer on the table, found the aerodynamic layout design of the drone he had completed, and took the initiative to make room.

At this time, Liang Zhanjun didn't care that the director was still next to him, and he leaned over and put his head close to the screen.

Jia Yueguang didn't care about this. He and Shen Yamin just stood next to Liang Zhanjun and tried their best to keep their eyes on the screen.

As for Zhao Yuefeng, he was in an awkward situation because the three people in front of him completely blocked the screen. He could only stand there and smile at Xu Yuan, waiting for Liang Zhanjun and the others to check the design plan first.

As Liang Zhanjun's eyes fell on the screen, he immediately saw the shape of a drone with a traditional layout.

Even if it is just a drawing, it gives people a sense of streamlined beauty.

Then, as the page scrolled, the theoretical parameters of the drone jumped into people's eyes, but they seemed to have seen something very shocking.

His eyes widened and became a little dazed for a moment.

"The aircraft is 12.2 meters long, has a wingspan of 24 meters, and a maximum take-off weight of 6.2 tons,"

"External load capacity: 2.3 tons."

"A flight of tens of thousands of kilometers?"

Liang Zhanjun couldn't help but look more shocked every time he read out a set of data.

Even if he racked his brains, he couldn't believe that such parameters could actually be a drone.

Finally, he took a deep breath, temporarily suppressed the surging emotions in his heart, looked at Xu Yuan very seriously and asked:
"Is this design a drone or a bomber?"

When Xu Yuan heard Liang Zhanjun's question, he was not surprised at all by his reaction.

After all, drones can achieve such terrifying performance parameters, which makes them much more useful than bombers in some ways. What's more, what Liang Zhanjun talked about are only some of the functions.
