Not long ago, Valena took a flight to Tokyo Bay, and this feat attracted the attention of the world. Valena's appearance greatly boosted the morale of the people of the Bear Kingdom.

Behind Valena's reckless action was the Xiong military's praise for the J-31, and its Ministry of National Defense also strongly recommended that Boss Pu introduce this fighter. It would be even better if he could get the technology at the same time.

For this reason, Cherrenko, as a representative of Bear Aviation Industry, has frequently traveled to the Ministry of Defense of the Rabbit Capital recently.

However, things obviously didn't go so smoothly. Rabbit refused to provide fighter technology and was even unwilling to export on a large scale. However, they proposed to help improve the Su-57, and made a suggestion of modification in a short time.

This really touched the itch of Xiong's senior management. The Su-57 was at least a child of its own family, which was more confident than other people's J-31. Boss Pu ordered Cherrenko to follow up. He came to Rabbit's Ministry of National Defense for this matter.

When he entered a conference room of the Ministry of Defense, Cherrenko suddenly saw a Su-57 scale model on the table. When this model came into his eyes, his eyes immediately lit up, and the military and aviation designers who accompanied him squeezed in.

This model is so beautiful, with smooth lines, flat appearance, reasonable layout and excellent design. The first moment Cheerrenko saw it, he felt that the Su-57 he wanted in his heart should look like this.

The reason why the fourth-generation aircraft made a stealth request is not to completely disappear in front of the radar, but to improve flight performance and shorten the distance discovered by the radar. It is like you could have seen the enemy a hundred meters away, but after stealth, it would approach ten meters in front of you. This is much more threatening.

But the original design of Su-57 has too many things that violate the stealth requirements. Not to mention that it can see the intake duct of the engine blades directly, the depression between the two engines under its belly is a huge radar reflection source.

A good stealth design must require a smooth appearance of the fuselage, and the belly of the f-22 and J-20 are very flat, which is not unreasonable. In order to level it, the b-2 bomber with the strongest stealth capability simply moved the engine air intake to the back of the aircraft, and it is difficult for the ground radar to detect it.

Xiongda's aviation R&D personnel had a deviation in their perception of invisibility. After Su-57 was finalized, they found that the problem was already difficult to reverse. It always required a new blow-out tunnel, calculating the intensity and conducting experiments. This was no longer a problem of spending money, and even involved internal factional struggles.

Internal struggle is more terrible than external attacks, because both sides know the truth and the lethality will be particularly huge. For this reason, no one dares to act rashly.

Now that he saw such an improved Su-57 model, Cherrenko was so excited that he was completely selfless. He approached and looked at the details of the model carefully, and his admiration blurted out.

"Okay, the belly of the machine is well modified. The concave and convex reflection source is flattened and the depth of the bomb bay is increased. This must be modified."

As soon as Cherrenko spoke, the deputy chief officer from Sukhoi behind him stared at the rear of the model for a long time, frowned and pursed his lips. After a while, he said: "The stealth design of our front fuselage is quite good, but the rear fuselage is indeed bad. This model has made a major change in the rear fuselage."

Other stealth fighters have tried to cover the engine nozzles to reduce infrared radiation and avoid being discovered by the increasingly developed photoelectric detection devices. However, Su-57 is careless about this, and its designers obviously did not consider this issue.

As for designs like the S-shaped air intake, it is no problem. These details make the Su-57 truly called the fourth-generation aircraft. After seeing this model, Cherrenko and others carefully studied it for more than an hour, completely leaving the original person in the meeting aside.

Xiao Jinlang was also at the meeting, and a general from the Rabbit Ministry of National Defense asked him in a low voice, "Why did you get this model so quickly? Judging from the Russians' fascinated appearance, they will definitely be able to pull them into the water this time."

This question made Xiao Jinlang smile bitterly, why did he go so quickly and smoothly? Because this model was simply taken from the Central Institute of Fluid Mechanics in Moscow in the End of the World. For this final design, the Russians struggled for another ten years.

After Cherrenko and others saw it almost, Xiao Jinlang stepped forward and coughed, "Everyone, this is a modification plan for our aviation designers to Su-57. If you are interested, we can start the formal talks."

Interested? Of course I am interested.

There are many types of fighter jet development, and it is only one of them, and there are other ways. For example, the F-35 project is a group of Eagle Sauce who pays money to Lockheed Martin for development and production.

In addition to paying 'parties', there are also cooperation in developing and developing multiple countries. For example, the ef-2000 fighter jets in Europe were cooperating with several countries. However, this approach is quite pitiful.

There is also technology transfer, and the introduction of Su-27 by rabbit is this type. Another type is "improvement on behalf of others", such as the unlucky "Pearl of Peace". This plan cannot be said that the rabbit has not gained benefits, it can only be said that the benefits obtained are not enough.

In addition to the above, there is another type called technical consultation. The general idea is that the things you make are not good enough. If you want to find a great person to ask how you should do it? This also requires you to pay.

Judging from the current situation, Xiong Da and Rabbit are still in the initial stage of technical consultation on the Su-57 project. Cheerlenko and others are actually not willing to take out their Su-57 design information. However, when they saw the model provided by Xiao Jinlang, they immediately felt relieved.

The model that Rabbit "Randomly" seems to be stronger than what we do ourselves. Are we really too behind? Alas...

With a model as a foundation, the subsequent cooperation negotiations will be much easier. After the negotiations, Cherrenko kept providing his own Su-57 design framework and details.

A certain "design team" represented by Xiao Jinlang modified the design at an extremely fast speed every time, and each time it was changed quickly and well, and extremely exquisite.

Cheer Nian Ko was strange. He always felt that the "team" behind Xiao Jinlang had changed too quickly, and his understanding of Su-57 was very deep. Every time he changed it just right, it was not only in line with the technical capabilities that Xiong Da can achieve, but also did not deliberately pursue technological progress.

This rapid "modification" ability made Cherrenko both happy and shocked. He was really impressed by the excellent design skills of Rabbit. After only three months of cooperation between the two parties, the newly modified Su-57 began to conduct full-size model wind tunnel testing, which was naturally a great success.

"Hahaha... Davarich, you guys are so good."

"It was unimaginable in the past to complete the body modification task so quickly, and also saved us a lot of money and time."

"It's so glad that you saved us an important defense project and saved our army."

In this era of rapid development, backwardness is probably not a beating, but backwardness is probably a perish. Human beings have developed for thousands of years in farming civilization, hundreds of years in mechanical civilization, and decades in information civilization. No one knows what will happen next?

The unknown does not necessarily make people curious, and even represents fear. Seeing the rabbit making rapid progress, the entire Western world is now becoming anxious. If the rabbit has a strength that is greater than that of the United States, what would the Bear Congress think?
