Chapter 1775: technical consulting

Not long ago, Valena drove to Tokyo Bay for a trip, a feat that made the world look down. Valina's appearance has greatly boosted the morale of Xiong Daguo.
Behind Valina's reckless operation, Xiong Dajun's praise for the J-31 was full, and its Ministry of National Defense also strongly suggested that Boss introduced this fighter. It would be better if you could get the technology by the way.
To this end, Cherelenko, as a representative of the Bear Aviation Industry, has frequently traveled to the Ministry of Defense of the Rabbit Empire.
However, things were obviously not so smooth. Rabbit refused to provide fighter technology and was even unwilling to export on a large scale. However, they suggested that they could help improve the Su-57, and they made suggestions in a short time.
This time it really scratched the bear's itch, and improved Su-57 because he is a child of his own family, which is more energetic than the Jian-31 of others. Mr. Pu ordered Cjelenko to follow up. He came to the Ministry of Defense of the Rabbit for this purpose.
When stepping into a conference room of the Ministry of Defense, Cherlenko suddenly saw a scale model of the Su-57 on the table. When this model came into view, his eyes lighted up immediately, and the military and aviation designers accompanying him came crowding.
This model is really beautiful, with smooth lines, flat shape, reasonable layout and good design. The first moment Cherlenko saw it, he felt that the Su-57 he wanted should be like this.
The reason why the fourth-generation aircraft made stealth requirements was not to completely disappear in front of the radar, but to improve flight performance and shorten the distance discovered by the radar. It's as if you could have seen the enemy at a distance of 100 meters, and he would approach ten meters in front of you after hiding. This threat is mostly.
The original design of the Cosu-57 has too many violations of the stealth requirements. Not to mention that it can directly see the air inlet of the engine blades. The depression between the two engines under the belly of the machine is a huge radar reflection source. .
A good stealth design necessarily requires a smooth body surface, and the belly of the F-22 and F-20 is very flat, which is not unreasonable. At present, the B-2 bomber with the strongest stealth ability has moved the engine's air inlet to the back for the sake of smoothness, and it is difficult for the ground radar to find it.
Xiong Da's aviation R & D personnel have a biased perception of invisibility. After the Su-57 was finalized, it was found that the problem was already hard to come by. Overthrowing has always required re-blow holes, calculating strength, and experimenting. This is no longer a question of spending money, or even an issue of internal factional struggle.
The internal struggle is more terrifying than the external attack, because both sides of the enemy know the root cause, and the lethality will be particularly great. No one dares to act lightly for this.
But now seeing such an improved Su-57 model, Cellenko was suddenly ecstatic. He got close to look at the details of the model, and the admiration in his heart blurted out.
"Okay, the belly is better. It smoothes out the uneven reflection source and increases the depth of the bomb bay. This must be changed."
As soon as Cherelenko spoke, the deputy chief from behind Sukhoi also stared at the rear fuselage of the model for a long time, frowning and pouting again. After a while, he said: Well, the rear fuselage is really bad. And this model has a major change in the rear fuselage. "
Other stealth fighters have tried to cover up the engine nozzle, reduce infrared radiation, and avoid being detected by the more and more advanced photoelectric detection devices. Cosu-57 was careless about this, and its designers obviously did not consider this issue.
As for the design like the S-shaped air inlet, it is even more important. The addition of these details makes the Su-57 truly a fourth-generation machine. After seeing this model, Cherelenko and others carefully studied for more than an hour, completely leaving the original interviewees aside.
Xiao Jinlang was also at the talks. A general from the Rabbit Ministry of Defense whispered to him, "Why did you get this model so quickly? Look at Mao Zi's fascination, and I will definitely pull them into the water this time."
This question made Xiao Jinlang smile bitterly-why is it so fast and so smooth? Because this model was taken from the Central Institute of Fluid Mechanics in Moscow in the last days. For this final design, Mao Zi tossed for another ten years.
After waiting for Cherelenko and others to see it, Xiao Jinlang stepped forward and coughed. "Everyone, this is a modification plan for Su-57 by our aviation designers. If you are interested, we can start the formal talks. "
interest? Of course I'm interested.
There are many types of fighter R & D. R & D alone is just one of them, and there are other ways. For example, the F-35 project is a small brother of Eagle Sauce handing over money to Loma for research and development.
In addition to paying 'parts of money', there are also many countries cooperating in development. For example, in Europe, the EF-2000 fighter plane is a bunch of cooperation. However, this approach is pitfall.
There is also technology transfer. The introduction of Su-27 by rabbits is this type. The other is ‘improvement’, such as the unfortunate ‘Pearl of Peace’ plan. This plan can't say that the rabbit has not benefited, it can only be said that the benefit is not enough.
In addition to the above, there is a technique called technical consultation. The main idea is that what I do is not good enough. I want to find a cow to ask what should I do? This is also to pay.
Judging from the current situation, Xiong Daihe Rabbit is still in the initial stage of technical consultation on the Su-57 project. In fact, Cherelenko and others are still reluctant to take out the design information of their Su-57. It can be seen that this model provided by Xiao Jinlang suddenly seemed to take a reassurance.
It seems that a model that Rabbit "randomly" made is stronger than what we made ourselves. Are we really too far behind? Ugh…….
With a model, the next cooperation negotiation is much easier. Cherlenko has continuously provided its own Su-57 design framework and details after the negotiations.
A certain 'design team' represented by Xiao Jinlang repeatedly modified the design at an extremely fast speed, and each time it changed quickly and well, and it was exquisite.
Cherelenko is strange. I always feel that the 'team' behind Xiao Jinlang has changed too quickly, and the understanding of Su-57 is particularly deep. Each time it is changed, it is just right-in line with Xiongda's current ability Technical capabilities, and will not deliberately pursue technological progress.
This rapid 'modification' ability surprised and surprised Cherelenko, and was really impressed by the outstanding design skills of the rabbit counterparts. Wind tunnel testing of full-scale models-this is naturally a great success.
"Hahaha ... Davarich, you guys are so nice."
"Completing the airframe modification task so quickly was unimaginable in the past and saved us a lot of money and time."
"I'm so glad you saved an important defense project for us and saved our army."
In this era of rapid development, backwardness is probably not to be beaten, backwardness is to perish. Human beings have developed thousands of years in farming civilization, hundreds of years in mechanical civilization, and information civilization has developed for decades. Who knows what will happen next?
The unknown does not necessarily make people curious or even fear. Watching the rabbit progress rapidly, the entire western world is now getting restless. If one of the rabbits has more strength than the United States, what do the bears think?
Cherlenko may not think so much, but the improvement of Su-57 did give him great comfort. Just when he felt relieved, Xiao Jinlang put forward another suggestion ... Should we produce a batch of improved Su-57 for you?
