Chapter 1775 Technical Consultation

Not long ago, Valena took a plane to Tokyo Bay for a stroll, and this feat caught the attention of the world. Valianna's appearance greatly boosted the morale of the people of Xiong Daguo.

Behind Valina's reckless actions, Xiongda's military is full of praise for the J-31, and its Ministry of Defense also strongly recommends that Mr. Pu introduce this fighter. It would be even better if you can get the technology in hand by the way.

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

However, things obviously did not go so smoothly. Rabbit refused to provide fighter technology, and was even unwilling to export it on a large scale. But they suggested that they could help improve the Su-57, and they made suggestions for modifications in a very short time.

This time I really scratched the itch of Xiongda's high-level executives. The improved Su-57 is a child of my own family anyway, which is more confident to use than other people's J-31. Boss Pu ordered Cherlenko to follow up, and he came to the Rabbit Defense Ministry this time for this matter.

And when he stepped into a meeting room of the Ministry of Defense, Cherrenko suddenly saw a scale model of the Su-57 on the table. When this model model came into view, his eyes lit up immediately, and the military and aviation designers who accompanied him crowded up.

This model is really beautiful, smooth lines, flat shape, logical layout and good design. The first moment Cherlenko saw it, he felt that the Su-57 he wanted should look like this.

The reason why the fourth-generation aircraft proposes stealth requirements is not to completely disappear in front of the radar, but to improve flight performance and shorten the distance detected by radar. It's as if you can see the enemy from a hundred meters away, but after being invisible, he will approach you ten meters in front of you. This threat is much greater.

However, the original design of the Su-57 has too many places that violate the stealth requirements. Not to mention that it is directly connected to the air inlet where the engine blades can be seen. The depression between the two engines under the belly is a huge radar reflection source. .

A good stealth design must have a smooth appearance. The belly of the F-22 and J-20 are very flat, which is not unreasonable. At present, the B-2 bomber with the strongest stealth ability simply moved the engine inlet to the back of the aircraft for smoothness, making it difficult for ground radar to detect it.

However, Xiongda's aviation R&D personnel had a biased perception of invisibility. After the Su-57 was finalized, it was discovered that the problem was already serious. The demolition has always required re-blowing the tunnel, calculating the strength, and doing experiments. This is no longer a matter of spending money, but even involves internal factional struggles.

An internal struggle is more terrifying than an external attack, because both opposing parties know the truth, and the lethality will be enormous. For this reason no one dared to act rashly.

And now seeing such an improved Su-57 model, Cherlenko was so excited that he lost himself.

He leaned closer to carefully examine the details of the model, and blurted out the admiration in his heart.

"Okay, the belly of the aircraft is well modified. The concave and convex reflection sources have been flattened, and the depth of the bomb bay has been increased. This must be modified."

As soon as Cherlenko opened his mouth, the deputy chief engineer from Sukhoi behind him also stared at the rear fuselage of the model for a long time, frowned and pursed his lips, and said after a while: "The stealth design of our front fuselage is still It’s okay, but the rear fuselage is really bad. And this model has made a big change to 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. But the Su-57 didn't care about this, and its designers obviously didn't consider this issue.

As for designs such as S-shaped inlets, it is not a problem. The addition of these details makes the Su-57 truly a fourth-generation aircraft. After seeing this model, Cherlenko and others studied it carefully for more than an hour, completely leaving the original interviewee aside.

Xiao Jinlang was also at the meeting, and a general from the Rabbit Ministry of National Defense asked him in a low voice, "How did you finish this model so quickly? Seeing how fascinated Maozi is, this time will definitely drag them into trouble."

This question made Xiao Jinlang smile wryly—why did it go so smoothly so quickly? Because this model is basically taken from the Moscow Central Institute of Fluid Mechanics in the last days. For this final design, Maozi continued to struggle for another ten years.

After Cherlenko and the others had finished reading it, Xiao Jinlang stepped forward and coughed, "Everyone, this is a modification plan of our aviation designers for the Su-57. If you are interested, we can start a formal meeting. "

interest? Of course I am interested.

There are many types of fighter development, independent research and development is only one of them, and there are other ways. For example, for the F-35 project, Yingjiang’s younger brother paid part of the money to Lockheed Martin for development and production.

In addition to paying 'partial money', there are also multi-country cooperative developments. For example, the European EF-2000 fighter jet is a joint effort of several countries. However, this approach is rather tricky.

There is also technology transfer, and the introduction of Su-27 by the rabbit is this type. There is another kind of "substituting improvement", such as the unlucky "Peace Pearl" project. This plan cannot say that the rabbits have not benefited, only that the benefits they have received are not enough.

In addition to the above, there is another kind called technical consultation. The general idea is that the things I made are not good enough. I want to find a good person to ask what should I do? This is also paid for.

Judging from the current situation, Xiong Da and Rabbit are still in the preliminary stage of technical consultation on the Su-57 project. In fact, Cherlenko and others were not very willing to show their Su-57 design materials. It can be seen that the model provided by Xiao Jinlang immediately seemed to be reassured.

A model that the rabbit 'casually' got seems to be stronger than our own. Are we really too far behind? Ugh…….

With a basic model, the subsequent cooperation negotiations will be much easier. After the negotiations, Cherrenko continued to provide his own Su-57 design framework and its details.

A certain "design team" represented by Xiao Jinlang has revised the design at an extremely fast speed every time, and every time the modification is fast, good, and exquisite.

Cherlenko was surprised. He always felt that the "team" behind Xiao Jinlang made changes too quickly, and his understanding of the Su-57 was very deep. technical capabilities, and will not deliberately pursue technological progress.

This kind of quick 'modification' ability made Cherlenko both happy and surprised, and he was really amazed by the excellent design skills of his fellow rabbits. Just three months after the cooperation between the two parties, the newly modified Su-57 began to conduct wind tunnel tests on full-scale models-this was naturally a great success.

"Hahaha... Davarish, you are so kind."

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

"I'm so glad you saved an important defense program for us, our military."

In this era of rapid development, lagging behind may not mean being beaten, and lagging behind may mean perishing. Human beings have developed farming civilization for thousands of years, mechanical civilization for hundreds of years, and information civilization for decades. No one knows what will happen next?

The unknown does not necessarily make people curious, or even represent fear. Watching Rabbit progress by leaps and bounds, now the whole western world is getting restless. If one day the rabbit's strength surpasses that of the United States, what will the Bear Conference think?

Cherrenko may not have thought that much, but the improvement of the Su-57 did give him great comfort. And just when he felt relieved, Xiao Jinlang made another suggestion... Should we produce a batch of improved Su-57 for you?
