Although he had already obtained the engine structure diagram of the F119, Chen Nian did not plan to start drawing it immediately.

On the one hand, it was because he still had the structural diagram of the body in his hand that he hadn't finished drawing, and on the other hand, because if he really handed over this thing like this, he really couldn't explain its source.

The best way is to ask Lin Yongming for a copy of the structural reasoning diagram of F119 they have, and then improve it for the key details.

After all, most of the design principles of the F119 are actually known, and this work of "guessing the map" should have been in progress for a long time.

Then the plan is clear.

Work on the airframe first, quickly finish all the airframe structure drawings, and then turn to the engine!

Thinking of this, he did not hesitate for a moment, and immediately spread out the paper and began to draw.

Fortunately, the most complicated parts have basically been drawn, and the remaining parts such as the wings, hatches, and magazines are not too complicated, and it doesn't take much time overall.

Maybe it can be done in a week.

Chen Nian's pen was flying, but as he painted, he couldn't help but start to associate in his mind.

Why is this wing set up like this?

What is this little movable rudder face for?

At low speeds, the vortices in this part of the wing surface are completely changed.

What happens if you lose a wing?

.......

One question after another surfaced, and in a trance, he found that all the aerodynamics knowledge he had learned seemed to have been verified by practice at this moment.

His understanding of the design of the airplane's fuselage unconsciously went to another level.

What's more, he vaguely established a new cognition in his heart:

Perception of flight control.

Yes, not only does the design of the airframe serve the pneumatic layout in its complete state, it also takes into account the situation when the airframe is damaged!

What to do if the wing is broken? What to do if the steering rudder fails? What should I do if the vector spout is damaged?

It's all a problem.

Although I can't find the answer yet, maybe after the analysis of the control module is completed, everything will be solved.

Chen Nian subconsciously opened the system interface.

It's like looking at the schedule at hand, and I don't expect to see anything new.

But to his surprise, there was something new!

The parsing source point requirements of the control module have become lower.

Became 0.95 source points.

Obviously, this time the source point was lowered after I had an understanding of the flight control system.

In other words, your own knowledge can also reduce the difficulty of analysis!

---- no, it's not that the ideas I just had reduced the difficulty, but my systematic study of aerodynamics, to a certain extent, has achieved the effect of bypassing, so the difficulty has been reduced.

Doesn't that mean that one day, when one's knowledge system reaches a relatively complete and profound level, most of the analysis consumption will decrease?

Damn, is this worth it?

Learn, learn to die!

Chen Nian became more and more excited, he had almost seen that bright future.......

......

And while Chen Nian was drawing and studying, in a diplomatic hotel in the imperial capital, Marokov was sitting leisurely on a comfortable and soft leather sofa drinking vodka.

Sitting opposite sat Yevgeny, a well-known engine designer in Russia, an improved version of the AL-31FN engine from him and his colleagues at the Rurika Design Bureau.

"Now it seems that Huaxia has indeed not found the defects of our engine, if we can continue to maintain the mystery of the technology, the future procurement negotiations should be very smooth."

Hearing Yevgeny's words, Marokov said with a little dissatisfaction:

"It's not that we didn't find it, it's that our engine has no defects at all!"

"Yevgeny, you have to be careful with your words, this is not only a sales project, but also a diplomatic action."

"We want to rely on this export to establish friendly relations with the other group, and let them see our sincerity."

"So, we have to do everything to the best of our ability, flaw, don't use this word again!"

Evgeny spread his hands helplessly and replied:

"Okay, okay."

"But in fact, all engines will be defective, even the most advanced F-135 on the American side."

"The reason why I say this is just based on a realistic attitude."

"There is no truth from facts!"

Marokov interrupted him, and then continued:

"Evgeny, I want to ask you a question."

"If you have a loyal and obedient hound who has done you a lot of credit, and he has made the hares and foxes in your house pile up mountains, what do you think of it?"

After thinking for a moment, Evgeny replied:

"It's my hero and my friend."

"What if one day someone tells you that it's not that perfect? What if someone told you that his nose wasn't sharp enough, that he wasn't fast enough, that his body wasn't strong enough, and that he even made frequent mistakes in hunting? ”

"Uh...... That doesn't change my opinion of it, it's still my hero. ”

"That's right!"

Marokov nodded in satisfaction.

"The sale of AL-31FN is such a scene, the Chinese people need a working hunting dog, and they can't care what kind of shortcomings this hunting dog has."

"As long as you can hunt, you're a good dog."

"So why should we go to the point of reminding them, 'This is an imperfect hound.'"

"Of course I know that the AL-31FN isn't perfect, especially when used as a single shot---- but it's the best option for both of us, isn't it?"

Hearing Marokov's explanation, Evgeny sighed and said with a little emotion:

"That's exactly what happened."

"But you surprised me a little---- I thought you were just a cunning merchant."

"But it seems, you're really looking for a win-win situation."

Marokov smiled and replied:

"At the national level, there is room for the 'cunning' trait."

"We're up against some of the best people in the country, who, like us, are desperate to find our flaws and get the best out of them."

"Under such a high-intensity confrontation, it's useless to be smart."

"Like the previous negotiations, do you think they were really persuaded by my simple words?"

"No, they are persuaded by the objective fact that 'no defects can be found.'"

"Their technology is far inferior to ours, so even if we know there is a problem, we have to accept it."

"It's really sad......"

The expression on Marokov's face became a little strange, he was obviously lamenting Huaxia's powerlessness, but at this moment, he thought of something more.

And Evgeny also keenly captured the changes in his mood, and after just a little thought, he understood what the other party was thinking.

"yes, that's sad."

"When you're not as strong as someone else, even if it's just in one area, you have to make huge compromises."

"That's the rule of the jungle."

"But....... Obviously, there will be fewer and fewer such things in Huaxia in the future, and they are gradually growing up. ”

"But....... What about us? ”

The words fell, and the two fell silent together.

At this moment, the joy of the smooth progress of the AL-31FN contract negotiations seems to have been diluted a lot.
