Chapter 841: Fudge with models

During the Cold War, the advancement of military science and technology was quite rapid. Generations of fighters were constantly being developed, but in later generations, the pace of military science and technology slowed down when the Cold War ended.
Now, Eagle Country has completed the research and development of three generations of aircraft. The three most important fighters, F-14, F-15, and F-16, are already in service, while Xiong Country has already developed the MiG-29. , But Su-27 still needs several years of work to perfect.
In the research and development of military aircraft, the Eagle State has always been ahead of the Xiong State. Just when Xiong State began to mature the third-generation aircraft, the Eagle State was already planning the fourth-generation aircraft.
An outstanding feature of the fourth-generation aircraft is stealth, which must have the goal of hiding itself in front of the radar.
This seems to be an impossible technology. Now, if researchers all over the world hear about the invisibility, they must think it is a fantasy. Even Eagle Country itself finds it incredible, but they have worked it out.
Their first stealth aircraft, the F-117, is being built intensively and will soon mature. However, this aircraft is an out-and-out attack aircraft, even though it starts with F. To make it capable of air combat, that is unthinkable.
Since stealth was used as the first indicator in the design, the shape of this aircraft looks very special, with edges and corners, and it does not conform to aerodynamics at all. There are even many people who know the inside story. I wonder if it can fly.
Of course Qin Guan knew these things. He also knew that the success of the F-117 had greatly excited the Eagle State Air Force. They had already begun plotting other stealth aircraft.
For example, a stealth fighter. It is still two or three years before the Eagle State Air Force proposes the fourth-generation aircraft project. However, all major military aircraft research and development companies have begun to look in line.
Anyway, idleness is also idleness. Qin Guan brought this thing purely to fool people.
Sure enough, when Pellehak saw this model, he immediately felt that his heart was beating wildly. When he looked at it with an expert eye, he knew that the shape of this aircraft was so strange and it was aimed at stealth. The body is composed of various inclined planes, which can reflect radar waves in other directions, which will cause the radar waves of the other party to receive too few radar waves and reduce the probability of detection.
The layman watched the excitement, and the expert watched the doorway. Pellehak felt very encouraged by this look.
"What kind of plane is this?" Pellehake concealed his inner excitement and asked Qin Guan.
Qin Guan glanced at it and said, "Our own pre-researched next-generation fighter." When he said this, he had a casual expression, as if he felt that the project was nothing.
If a country’s military aircraft development wants to embark on a sound development track, it must be equipped with one generation, and a pre-research generation. This pre-research cannot be lost.
When Han Guo was developing the J-10, he had just completed a single-seat test flight. Song Lao took a team of people and began to develop the layout of the next generation of fighters. Therefore, the later J-20 could be horizontal. This is the result of pre-research in advance.
But now, Qin Guan said pre-research, which means that the development of military aircraft in the Han country is on the right track. After all, three-generation aircraft such as the F-14 have been developed.
Pre-researched next-generation fighter? Pellehak continued to conceal his inner excitement and said, "The shape of your pre-researched aircraft looks so special."
"Yes." Qin Guan continued: "We have already foreseen that if the fighter plane can be hidden in front of the radar, it will play a considerable role. We have built an electromagnetic laboratory to explore the layout of the fighter plane. The current model is one of the results."
As Qin Guan said, the eyes of the person on the other side shone even more. Pellehack had seen the appearance of the F-117. In their words, it was like a pile of shit, and it was to be able to fly.
However, the model in front of me has a good combination of appearance and aerodynamic layout, without greatly reducing the flight performance, it is simply perfect.
Pellehake heard what Qin Guan said, and already had an idea in his mind, and said, "Can you share the technology with us on this verification machine? We can also buy it at a cost."
It is said that the Air Force is quite satisfied with the F-117 and is already planning to conduct pre-research on the next generation of fighter jets. If it can buy the technology of this aircraft and change its Tomcat fighter, it will become a fighter jet. Stealth cat.
Thinking of this, he was completely tempted.
"No, no, we got it through years of hard work, and we absolutely can't sell it." Qin Guan said: "Our scientific and technical personnel have spent so much effort to sum up the reflection formulas one by one."
Just look at a shape, can you imitate it?
The answer is no. The shape of the fighter is blown out by a blowing hole, and this stealth shape was researched in a special electromagnetic laboratory. There are complicated formulas for how to place each outside. This shape , At most it is just a reference. If you want to get the technology, you must get the formulas and calculation results.
Of course, Qin Guan said nothing.
"Is there no other way?" Pellehake asked disappointedly: "Can we change technology for technology?"
Hearing this, Qin Guan thought for a long time and said: "If technology is changed, we can consider it. What we lack most now is the welding technology of titanium alloys. As long as your titanium alloy laser welding technology, including equipment, Provide it to us and we can give you the pre-research results of our next-generation fighter."
Hearing Qin Guan's words, Pellehake also frowned. This technique was the unique secret of their Grumman company.
The MiG-23 is also a variable swept wing, but compared with the variable swept wing of the Tomcat, it is a world of difference. What is the reason?
In many respects, it is an indisputable fact that the MiG-23 is too heavy. The overweight is due to the variable swept wing shaft. The MiG-23 uses steel, while Grumman uses titanium. alloy.
In order to create a Tomcat with variable swept wings, Grumman has also gone through a lot of scientific and technological research. The most important thing is the wing box with variable swept wings. This titanium alloy wing box is made of Grumman. The company invented the vacuum laser beam welding technology to achieve.
After repeated flights, the welding parts of these wing boxes have the same strength as other parts, which is also a necessary technology for the tomcat to spread its wings and fly.
Han Guo wants to imitate Tomcat. This technology is already a stumbling block and must be overcome.
