Although he has obtained the engine structure diagram of the F119, Chen Nian does not plan to start drawing it immediately.
On the one hand, it's because I still have an unfinished structural diagram of the body in my hand, and on the other hand, it's because if I really hand over this thing like this, I really can't explain its origin.
The best way is to ask Lin Yongming for a structural inference diagram of the F119 they have, and then improve the key details yourself.
After all, most of the design principles of the F119 are actually known, and this "guessing" work should have already been in progress.
Then the plan is clear.
Let’s work on the airframe first, quickly complete all the airframe structural diagrams, and then move on to the engine!
Thinking of this, he didn't hesitate for a moment and immediately spread out the paper and started drawing.
Fortunately, the most complicated parts have basically been painted, and now the remaining parts, such as the wings, hatch covers, and magazine compartments, are not too complicated and generally do not take too much time.
Maybe it can be done in a week.
Chen Nian's brush strokes flew quickly, but as he drew, he couldn't help but start to make associations in his mind.
Why is this wing set up like this?
What is this small movable helm used for?
At low speeds, the vortices on this part of the airfoil completely change.
What happens if you lose a wing?
.......
Questions emerged one after another, and he suddenly found that all the aerodynamics-related knowledge he had learned seemed to be verified by practice at this moment.
His understanding of the aircraft body design has unknowingly reached a new level.
More importantly, he vaguely established a new understanding in his heart:
Knowledge about flight control.
Yes, the airframe design not only serves the aerodynamic layout in the complete state, it also considers the situation when the airframe is damaged!
What to do if the wing is damaged? 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 everything will be solved after the analysis of the control module is completed.
Chen Nian subconsciously opened the system interface.
This action was originally like checking the schedule casually, without expecting to see anything new.
But to his surprise, there was something new!
The parsing source point requirements of the control module have become lower.
It became 0.95 source points.
Obviously, this source point reduction occurred after I gained understanding of the flight control system.
In other words, your own knowledge can also reduce the difficulty of analysis!
----No, it wasn't the ideas I just had that lowered the difficulty, but my systematic study of aerodynamics, which to a certain extent achieved the effect of drawing parallels, so the difficulty was lowered.
Doesn't that mean that if one day, when your knowledge system reaches a relatively complete and profound level, most of the analysis consumption will decrease?
Damn it, is this even a big deal?
Study, learn to death!
Chen Nian became more and more excited, he had almost seen the bright future...
...
While Chen Nian was drawing and studying like crazy, in a diplomatic hotel in the imperial capital, Marokov was sitting on a comfortable and soft leather sofa with a leisurely expression, drinking vodka.
Sitting opposite is Yevgeny, a well-known engine designer in Russia. The improved AL-31FN engine was designed by him and his colleagues at the Iulika Design Bureau.
"Now it seems that China has indeed found no flaws in our engine. If we can continue to maintain the mystery of the technology, future procurement negotiations should go smoothly."
After hearing what Yevgeny said, Marokov said with some dissatisfaction:
"It's not that we didn't find it, it's that our engine has no defects at all!"
"Yevgeny, you have to pay attention to your wording. 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 must do our best in everything. Don't use the word defect again in the future!"
Yevgeny spread his hands helplessly and replied:
"Alright alright."
"But in fact, all engines have defects, even the most advanced F-135 in the United States is no exception."
"The reason why I say this is just based on a realistic attitude."
"There is no truth to facts!"
Marokov interrupted him and then continued:
"Yevgeny, I want to ask you a question."
"If you have a loyal and obedient hound, and he has done a lot of work for you, and he has made a mountain of rabbits and foxes in your house, what do you think of him at this time?"
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 actually 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 even makes frequent mistakes in hunting?"
"Well...it doesn't change my opinion of it, it's still a credit to me."
"now it's right!"
Marokov nodded with satisfaction.
"The sales of AL-31FN are like this. The Chinese people need a useful hunting dog, and they can't care about the shortcomings of this hunting dog."
"As long as it can hunt, it's a good dog."
"So why do we bother ourselves by reminding them that 'this is an imperfect hound'?"
"Of course I know 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?"
After hearing Marokov's explanation, Yevgeny sighed and said with some emotion:
"That's true."
"But you surprised me - I thought you were just a cunning businessman."
"But it seems like you're really looking for a win-win situation."
Marokov smiled and replied:
"There is no room for cunningness at the national level."
"The opponents we face are the best people in this country. Like us, they are all deliberately trying to find our flaws and strive for the greatest interests for themselves."
"In such a high-intensity confrontation, it is useless to be clever."
"Just like the previous negotiations, do you think they were really convinced by my simple words?"
"No, they were convinced by the objective fact that 'no defects could be found'."
"Their technology is far inferior to ours, so even if they know there is a problem, they have to accept it."
"This is really sad..."
The expression on Marokov's face became a little strange. He was obviously lamenting the powerlessness of China, but at this moment, he thought of more things.
And Yevgeny also keenly caught the changes in his emotions. After just a moment of thinking, he understood what the other person was thinking.
"Yeah, that's really sad."
"When you are not as strong as others, even in a certain area, you have to make huge compromises."
"This is the law of the jungle."
"But...it's obvious that such things will become less and less common in China in the future. They are gradually growing up."
"But...what about us?"
After the words fell, the two of them fell into silence.
At this moment, the joy that the AL-31FN contract negotiations were proceeding smoothly seemed to be diluted a lot.
