Thrust, not all.

For aircraft design, the most important indicator of an engine is not the maximum thrust, but explosive power and stability.

Explosive power, that is, instantaneous power increase speed, is like a car driving on the road, some can accelerate [-] meters in three seconds, while others need six, seven seconds or even more.

The speed of acceleration directly reflects the performance of the car engine.

Of course.

To some extent, higher maximum thrust means higher explosive power, but at the same time with high explosive power, there will actually be a negative effect, which brings another important factor to measure engine performance- -

stability.

Stability is very, very important.

Stability does not only refer to the flameout problem, but also to keep the engine working as efficiently as possible in harsh environments. Fighters need to make various actions, such as low-altitude flight, rapid dive or vertical ascent, or roll in the air ,etc.

These actions will cause changes in the airflow at the intake port, and even changes in the direction of the airflow. Changes in the airflow will affect the operation of the entire engine, and it will be very difficult to maintain stability.

Lei Yong was surprised by the WZ-A1 engine, which has the stability threshold in the design evaluation data. It has the latest port piston design, coupled with the revision of the stator blades, the WZ-A1 engine can suddenly drop to zero at the air intake. Under normal circumstances, it can still continue to work stably for a period of time, and the compressor will not have a series of problems caused by internal pressure changes. It can also use the high pressure released by the piston to provide a second power to the aircraft.

Hearing Lei Yong and Bao Enhong's admiration, the others puffed up their chests and felt very proud.

Although most of the designs were completed by Academician Zhao, they are still members of the Warhawk team and have contributed to the engine design. At the same time, many people also discussed Zhao Yi, "What is Academician Zhao doing?"

"He seems to have been bored in the office for more than two days?"

"Is it a design?"

"Impossible to do design?" Lei Yong said, "Academician Zhao, it seems to be reading our report." He added, "Maybe, I'm not sure."

"is it?"

"What report?"

"..."

This time Lei Yong didn't speak, neither did Bao Enhong. She hurried to a corner and sat down, as if to avoid being noticed by others.

When the others found that Lei Yong didn't answer, they thought it was something confidential, so they didn't continue to ask. They were not worried about Zhao Yi, because there was a female assistant named Qian Hong who was in charge of taking care of his life.

If something went wrong, Qian Hong would definitely know.

In addition, Yuan Haitao also met Zhao Yi from outside the door a few times, so he didn't have to worry about anything.

While everyone was still discussing, the door of the office was suddenly opened, and Zhao Yi came out from inside. He seemed a little tired, but staring at the printed paper in his hand, he looked radiant.

"Everyone, come here."

Zhao Yi walked over and waved to everyone, "Everyone go to the conference room, I want to explain the work assignment."

"Oh."

Everyone agreed and hula la walked to the meeting room.

Yuan Haitao was familiar with Zhao Yi. He leaned over to look at the paper in Zhao Yi's hand, and asked in surprise, "This is... an airplane from a movie? It looks so good!"

"The shape I designed."

Zhao Yi was also a little proud, "It's pretty good," he said, pointing to Lei Yong and Bao Enhong, "The aircraft analysis report is very good, it gave me a lot of help, and I was able to complete this shape design."

"what?"

Lei Yong passed by and listened to it, and suddenly opened his mouth in surprise, "Academician Zhao, you said you have completed the shape design of the aircraft?"

"What's wrong?" Zhao Yi was a little puzzled.

Everyone else looked over.

"No, when did you finish it? How come it's so fast? It's impossible..." Lei Yong fell into confusion for a while, and he glanced at the plane diagram in Zhao Yi's hand, "And, this... should be from some movie Right? So... amazing..."

Zhao Yi said with satisfaction, "You also think it has a sense of art and technology, right? I think so too."

"Our Warhawk-1 generally has this shape. It is estimated that there will be revisions in the future, but there will be no major revisions."

Lei Yong couldn't accept it for a while.

When everyone else had entered the conference room, he was still standing in a daze, and Yuan Haitao was also standing beside him. He patted Lei Yong on the shoulder and said, "Have you noticed? The others don't care at all."

"Since you've come to the Warhawk team, as an old man, I want to remind you."

"You must have a big heart. Don't be surprised when you see what designs and researches Academician Zhao completes, but get used to it."

"Get used to it, and it becomes natural."

"You think it's unbelievable that Academician Zhao completed the aircraft shape design so quickly? Wrong, it seems normal to me. We can't do it, but he is Academician Zhao!"

"do you understand?"

"..."

Chapter 455 Academician Zhao is indeed testing us!

"Academician Zhao is a true genius, completely beyond the imagination of ordinary people, and we are ordinary people..."

"Ordinary people cannot understand genius."

"Knowledge is not at the same level, IQ is not at the same level, and world outlook is not at the same level. It's just like it's impossible for primitive people to understand why modern people are so smart and know so many things."

"Uh~~"

"Anyway, it's normal for Academician Zhao to complete the design quickly, so there is no need to be surprised, because he is Academician Zhao..."

After Lei Yong heard Yuan Haitao's words, these things kept wandering in his mind, and he kept repeating them, as if he was reciting something seriously, which made him look much calmer.

Not excited!

Not excited at all!

Most of the people in the meeting room were seated. Bao Enhong was sitting next to Lei Yong. She was still excited and puzzled. She turned her head and saw Lei Yong's calm expression. Is it strange? Academician Zhao completed the shape design so quickly."

"Nothing to get excited about."

Lei Yong suppressed the excitement in his heart, took a deep breath and nodded calmly, his tone full of sighs, "Because he is Academician Zhao!"

"—??"

Bao Enhong stared carefully at Lei Yong several times, "Why do I feel that you seem weird."

"nothing!"

In fact, Lei Yong is just pretending to be calm. It is impossible for him not to be excited and puzzled. He is an expert in aircraft design and development. He knows the process of aircraft shape design. It takes at least two months from the initial design to the final shape. half a year.

The shape design is not done by one person. Everyone in the team has to participate in the design, including the nose, wings, tail, cockpit, air intake, engine, landing gear, launch hanger, etc. Every part of the details is done by the team.

After the group completes the design, the collective is conducting repeated demonstrations before certain details can be determined.

Finally, the various parts are combined and the shape is corrected for the details.

This is the normal flow of shape design.

However, Academician Zhao only has a few days. Even if he had prepared beforehand, the time is too short. Most importantly, the team seems to have no other researchers related to aircraft design. The appearance must have been designed by Academician Zhao alone. of.

A person?

"Is this shape reliable?" Lei Yong suddenly felt skeptical, and quickly shook his head, putting aside all skeptical thoughts, "Academician Zhao is a real genius, what doubts? He led the team to design the engine, The expert group of the aviation group did not find any problems, and was praised and affirmed by various big figures."

"Ordinary people like me probably can't understand it, and it doesn't affect my perception at all to doubt Academician Zhao's design..."

Thinking of this, Lei Yong felt relieved.

Of course.

Lei Yong's ideas did not affect Bao Enhong. During the meeting, Bao Enhong kept looking at the outline drawing in his hand and said in a skeptical tone, "This design seems to have no problem, and it seems to have a big problem. It needs to be carefully demonstrated. Lei Yong, what do you think?"

"I think it's fine, absolutely fine."

"why?"

"Because he is Academician Zhao!" Lei Yong said with certainty.

Bao Enhong was stunned for a long time, and suddenly she knew why Lei Yong felt weird.

This guy……

It seems to be the kind of stupid fan that is said on the Internet!

……

In fact, only Bao Enhong and Lei Yong cared about the appearance design of Zhanying-1. The others just looked at the appearance design drawing in their hands and thought it was very beautiful and very technological.

That's it.

None of them are professional aircraft designers, and they don't think about any problems with the shape design, they just listen to the work explained by Zhao Yi.

Zhao Yi does care about other people's opinions, but what he cares about is whether the appearance is beautiful, not what is wrong with the design, because he is very clear about the design problems and does not need other people's opinions.

The core of this shape design is the engine, and the shape is to maximize the performance of the engine, so that the aircraft can be more flexible and adapt to various harsh environments.

Plus, it's beautiful.

Advanced fighter jets must be beautifully designed. Good looks are not only for men and women, fighter jets are the same. A fighter jet with good looks makes people feel very advanced at first glance. Otherwise, people are not interested in looking at it. not tall.

Form design is just the beginning.

There is still a long way to go to complete the design of all fighter jets. There is only a shell suitable for the engine, and the progress is about 20.00% complete.

The next step is more important.

At the meeting, Zhao Yi mainly communicated with the team leader sent by He Aviation Group. The team leader's name is Fei Zhengbin, and the team he leads is responsible for the communication between the War Eagle Group and other research institutes.

Zhao Yi explained to Fei Zhengbin that the main issue was the priority. The first thing to be completed was the research institute of related technologies for the cockpit, safety device components and missile brackets. They only knew the standard dimensions required for these components, but the design had to find another technology. Commissioner here.

These items are directly related to the shape of the aircraft and must be the first to be resolved.

The next step to be solved is the radar and signal jamming system, which need to be directly assembled on the fighter, or even the outer layer of the fighter, which will definitely affect the shape design.

After having a brief conversation with Fei Zhengbin, and raising the following requirements of the Warhawk Team, and asking him to urge other research institutes by the way, Zhao Yi explained the work to be done by the team.

First of all, it is the preparation for the manufacture of the engine prototype.

The manufacture of engine prototypes is very complicated, and many parts are not completed in one factory. The manufacture of turbine blades, supercharger blades, stator blades and front fan blades is a very troublesome thing, so preparations must be made in manufacturing , Communicate with the factory in advance and let them start making molds. Even if they don’t make the mold directly, they have to invest energy in preparation. After all, time is money and can’t be wasted.

"Captain Yuan, you should keep an eye on the manufacture of several types of blades, and go with the existing parameters. If they don't cooperate, then go to Director Liu of the Science and Technology Department. I will tell Director Liu in advance."

"If you encounter any technical problems, report them at any time!"

"it is good."

Zhao Yi also asked Wang Zhixin, Sun Lei, and Li Rongmao to be responsible for the preliminary work of prototype manufacturing, and they were all sent to the factory to supervise mold manufacturing, prototype manufacturing preparation, etc.

There are only a few people left in the Warhawk group.

Zhao Yi didn't care either.

He even felt that he was enough, the engine prototype manufacturing is a big deal, and other things can be put behind.

After the work was completed, Zhao Yi brought the content back to the aircraft design. He talked about the equipment of the Warhawk-1, "We want the most stable and advanced equipment."

"That's the requirement for every part."

"Stability is the most important thing, and advanced ones come in second. Because aircraft manufacturing is a long-term process, the equipment may have to be updated in a few years. For us, the most important thing is to make the aircraft fly. Advanced equipment is Things that need to be considered only when the aircraft is officially mass-produced and put into service."

That's not what Zhao Yi considered.

The most important thing at present is to design the aircraft and push the engine directly into the prototype manufacturing stage, but in any case, the aircraft design also needs to be approved.

It's not easy.

Therefore, the stability of aircraft performance is the most important thing. The main considerations of aircraft design and finalization are performance issues and stability issues.

In terms of appearance design, Zhao Yi is very confident in performance and stability, but it is not clear whether the equipment is stable. The optimal solution for selecting equipment is stability, and the design will also be based on the most stable equipment. design corrections.

Such a design will definitely pass the review.

In fact, there is still a problem with the current shape design, that is, the weight is a little bit high, and there are imperfections in the perfect design, and the use of system capabilities does not consider the weight issue. More shell materials will be used, which will lead to an increase in the overall weight. Fortunately, the increase is not high, and it is still within the coverage and tolerance of the engine performance.

"If you reduce the weight, it will not be worth the loss, because every place is designed perfectly."

"Foldable wings, adjustable upper air intake, adjustable modified tail, reserved landing gear, magazine..."

Zhao Yi carefully inspected the shape several times, but still felt that there was nothing to adjust. The simplified version could not be made easily. He somewhat understood why the media said that the F-35 in country M was overweight. What is the function of a fighter jet? If you want them all, the functions are complete, but it is too difficult to control the weight.

……

End of the meeting.

The entire Warhawk team became busy, and the only ones who were free were Lei Yong and Bao Enhong. The two of them were not assigned any work. The work of the Warhawk team seemed to have nothing to do with them. To be precise, they belonged to the "Warhawk Special Research Team". It is the work of the War Eagle Special Research Team. For the time being, it is only communicating with other research institutes, and the designers have no work.
