Although he has obtained the engine structure drawing of F119, Chen Nian does not intend to start drawing it immediately.

On the one hand, it's because I still have the structural diagram of the body in my hand, and on the other hand, it's because, if this thing is really handed over like this, I really can't explain its source.

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

After all, most of the design principles of the F119 are already known, and this "picture guessing" work should already be in progress.

The plan was clear.

Do the airframe first, quickly complete all the airframe structure diagrams, and then turn to the engine!

Thinking of this, without hesitation for a moment, he immediately spread out the paper and started drawing.

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

Maybe a week can do it.

Chen Nian writes like a fly, but as he draws, he involuntarily begins to associate in his mind.

Why is the wing set up like this?

What is this little movable rudder for?

At low speeds, the vortices in this part of the airfoil completely change.

What happens if you lose a wing?

Questions came up one after another, and suddenly he found that all the aerodynamics-related knowledge he had learned seemed to have been verified by practice at this moment.

His understanding of the aircraft's body design has unknowingly reached a new level.

More importantly, he vaguely established a new cognition in his heart:

Knowledge about flight control.

Yes, the body design is not only for the aerodynamic layout in the complete state, it also considers the situation when the body is damaged!

What if the wing is missing? What should I do if the steering rudder fails? What should I do if the vector nozzle is damaged?

These are all problems.

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.

This action was like checking the calendar casually, and I didn't expect to see anything new.

But to his surprise, there was something new!

The analysis source requirement of the control module has been lowered.

becomes 0.95 source points.

Obviously, the lowering of the source point this time happened 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 made lowered the difficulty, but my systematic study of aerodynamics, which to a certain extent achieved the effect of analogy, so I lowered the difficulty.

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

Fuck, is this okay?

Learn, learn from the dead!

Chen Nian became more and more excited, he almost saw the bright future.

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

Sitting opposite is Yevgeny, a well-known engine designer in Russia. The improved AL-31FN engine was made by him and his colleagues in the Rurika Design Bureau.

"It seems that Huaxia has indeed not discovered the defects of our engine. If we can continue to keep the mystery of the technology, future purchase negotiations should go smoothly."

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

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

"Evgeny, you have to pay attention to your wording. This is not only a sales project, but also a diplomatic action."

"We need to rely on this export to establish a friendly relationship with the other party's group and let them see our sincerity."

"Therefore, we must do everything to the best of our ability, and the vocabulary of defects should not be used in the future!"

Yevgeny spread his hands helplessly, and replied:

"Alright alright."

"But in fact, all engines will have defects, even the most advanced F-135 in the United States is no exception."

"The reason why I say this is only based on a pragmatic attitude."

"There is no seeking truth from facts!"

Marokov interrupted him, and then went on:

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

"If you have a loyal and obedient hunting dog, he has done a lot of credit for you, and he has piled up the hares and foxes in your house. At this time, what do you think of him?"

After thinking for a moment, Yevgeny replied:

"It is my hero and my friend."

"Then what if one day someone tells you that it is not that perfect? ​​What if someone tells you that his nose is not sensitive enough, his speed is not fast enough, his body is not strong enough, and he often makes mistakes in hunting?"

"Well it doesn't change my opinion about it, it's still my credit."

"now it's right!"

Marokov nodded in satisfaction.

"The sale of AL-31FN is such a scene. The Chinese people need a usable hunting dog, and they can't control the shortcomings of this hunting dog."

"As long as it can hunt, it's a good dog."

"So if that's the case, why would we bother to remind them 'this is an imperfect hound'?"

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

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

"That's true."

"But you surprised me a little—I thought you were just a cunning businessman."

"But it seems like you're really after a win-win situation."

Marokov smiled and replied:

"At the national level, there's no room for the trait 'cunning'."

"The opponents we are facing are all the best people in this country. Like us, they are trying to find our flaws and strive for the best interests for themselves."

"In such a high-intensity confrontation, it is useless to play smart."

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

"No, they were persuaded by the objective fact that 'no defect can be detected'."

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

"It's really sad."

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

And Yevgeny also keenly captured the changes in his emotions, and after thinking about it for a while, he understood what the other party was thinking.

"Yeah, it's really sad."

"When you are not as strong as others, even in a certain field, you have to make huge compromises."

"This is the law of the jungle."

"However. Obviously, such things will become less and less in China in the future, and they are gradually growing up."

"But what about us?"

The voice fell, and the two fell into silence together.

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