Chapter 1553 The Age of Invisibility (Second update, please subscribe)
Behind the Iron Curtain, there is a gold mine unknown to people!
As early as ten years ago, Li Yian used this sentence to describe the science and technology on the other side of the Iron Curtain.

Unlike the general contempt for Soviet and Eastern European scientists of this era, Li Yian attached great importance to scientists from the Soviet bloc. The reason was very simple - after the Cold War, the assimilation of the European and American scientific communities from the Soviet bloc immediately ushered in a technological leap.

In fact, as a matter of common sense, what did the Soviet Union rely on to compete with the United States during the Cold War?
It was precisely because their technology was not much inferior to that of the United States that the Soviet Union lagged behind in many areas, but they were leading in some areas. To a certain extent, this lead was one of the reasons why human science and technology took off in the decade after the end of the Cold War...Humanity was able to integrate the technology of the two superpowers.

It is for this reason that, after the end of the Hungarian crisis, Li Yian took advantage of the Soviet Union’s domestic passport and the visa-free policy of the Soviet bloc to absorb scientists within the Soviet bloc and use Soviet and Eastern European technology to promote his own technological development.

At the same time, scientific and technological intelligence was collected by sending students to the Soviet Union and collecting its scientific journals. What the 34-year-old Ufimchev didn't know was that his paper entitled "Edge Wave Behavior in Physical Diffraction Theory" was copied by international students in the university library half a month after it was released last year.

This is also a bug in the Soviet Union. According to the Soviet secrecy law, technical journals such as the Journal of the Moscow Institute of Radio Engineering are not allowed to be sold to foreigners. However, according to its tradition, all libraries will subscribe to such journals and put them on the library shelves.

Libraries are open to foreigners, especially university libraries, so when an international student saw this article, he immediately copied it down.

Then, he appeared in Chang'an.

This paper has attracted the interest not only of the academic community, but also of some related companies.

Just when they were conducting corresponding research based on the content of the paper, they unexpectedly came to Chang'an.

"…that is, the reflection intensity of an object to radar electromagnetic waves has nothing to do with the size of the object, but is proportional to the edge layout. It also explains how to calculate the radar reflection surface of the aircraft surface and edge…"

In the conference room of Nanyang Aerospace Industries, Ufimchev pointed to the diagram he had sketched on the whiteboard and continued:
"From this theory, we can draw a conclusion that even a huge aircraft can still greatly reduce the intensity of its reflected radar signal through reasonable design, so that the aircraft can achieve "stealth" on the radar screen."

Tan Ke, the company's chief engineer, looked at the diagram on the whiteboard and said:
"Mr. Ufichimov, your theory is indeed very unique, but after our preliminary research, we found that in order to realize your stealth theory, the aircraft needs to be designed into a rather bizarre statically unstable aerodynamic shape, which seems to be very difficult!"

"Yes, sir. This is indeed very difficult. It requires a more advanced flight control system. This is what the military says. The military believes that under current technical conditions, this aerodynamic shape is difficult to ensure flight safety."

Ufichimov shrugged helplessly. His theory was too advanced, so it did not attract enough attention from the Soviet military.

"Indeed, with current flight control systems, such an aerodynamic shape is difficult to ensure flight safety."

Zhang Ke, who was sitting next to Tan Ke, continued:

"But, this is only for now, sir. We have been testing the fly-by-wire flight control system. The results of the test are very optimistic. I think we can give it a try."

The fly-by-wire flight control system that Zhang Ke mentioned was the one that the company introduced from Ivor when the Canadian CF-105 fighter was discontinued a few years ago. Although the CF105 fighter was discontinued, its fly-by-wire flight control system is still very advanced. Although this analog fly-by-wire flight control system uses analog computers and servo actuators and the control signal is an analog signal, it is far from comparable to the later digital automatic flight control system.

However, the fly-by-wire flight control system replaces the traditional mechanical transmission by converting the pilot's control instructions into electrical signals to control the aircraft. This system not only reduces the complexity of mechanical transmission, but also implements active control technology, improving the overall performance and reliability of the aircraft.

That is why the company spent hundreds of thousands of pounds to introduce this technology and applied it to the latest models of C707 and C717 as early as last year.

At present, the company's fly-by-wire technology is the most advanced in the world.

Nodding, Tan Ke said:
"I think we can give it a try. If the aircraft can be invisible, it will definitely bring fundamental changes to the war..."

In this way, the discovery that was rejected in the Soviet Union was used in SEA, and Ufimchev's paper was highly valued.

As the discoverer of this theory, Ufimchev didn't even know what kind of changes his discovery would bring to air combat, but the changes had already happened after his paper was published.

Originally, Nanyang Aerospace Industries' research direction was only on radar-absorbing materials, but after discovering Ufichimov's theory, they naturally felt like they had found a treasure. Now with my joining, some corresponding changes will be brought about.

When Ufichimov joined Nanyang Aerospace Industries, the brothers Walter and Rimar Horton stood in front of a somewhat strange-looking airplane at the company's airport.

If there are any aviation history enthusiasts here, they will definitely recognize it. This is the ho229 fighter-bomber, Germany's doomsday fighter, which is well-known to the world for its unique flying wing layout.

Like many German engineers, the Horton brothers came to SEA 1 years ago and continued their research at Nanyang Aerospace Industries. Although they also participated in the development of F2 and F229 fighters, they did not stop their research on flying wing aircraft. Although their aircraft development was based on the Ho aircraft, after continuous wind tunnel tests and the assistance of electronic computers, the flying wing layout and control system were more perfect.

"Fly-by-wire."

Walter Horton, smoking a cigarette, said:

"In the past, the biggest problem of the Ho229 was its backward control system, but now fly-by-wire control can solve most of the control problems and its performance has been greatly improved."

"However, we must also see that even so, its maneuverability is far from comparable to that of fighter jets with traditional layouts."

Rimar Horton looked at the simple and unique exterior shape of the plane in front of him and said:
"So, I still maintain my original view that it is more suitable as a bomber than a fighter. The external structure of the flying wing layout is relatively simple, and the internal facilities are optimized, so the structural weight of the whole aircraft is relatively light. Moreover, under this layout, the internal space of the fuselage that can be used to carry supplies is larger, and the distribution of the load area is more scientific, so not only the load capacity is large, but the fuselage is also strong and reliable.

From the perspective of aerodynamic layout, it can be called a natural bomber!"

"Um,"

Walter Horton nodded and said.

"That's true. However, we have to consider the funding. This plane is a small plane built with experimental funds. As for the bomber..."

After taking a puff of cigarette, Walter Horton shrugged helplessly and said:
"The military's H1 bomber is still in production and improvement, and they are still in the discussion stage about the next-generation bomber. Under such circumstances, it is difficult for the military to support a new bomber project."

Sometimes this is the reality. All research requires funding. The Flying Wing Project is just an officially supported experimental project. Such experimental projects will not receive much funding.

It is even for this reason that they used small engines and designed this light flying wing aircraft.

"We can't worry about so many things now. Let's test fly it first. If its performance is as superior as we expected, I believe the military will not be able to ignore it."

Rimar Horton thought for a moment and said:
“After all, in terms of cost, it’s cheaper to make.”

The cost mentioned by Ruimar refers to the fact that the flying wing layout bomber has a simpler structure and is faster to manufacture compared to the traditional layout bomber.

After all, at its root, this project originated from the Third Reich's emergency fighter plan. At that time, Germany was short of materials and exhausted its resources. The first requirement for the fighter was that the structure should be as simple as possible, the cost must be as low as possible, and the least resources should be consumed.

Therefore, its manufacturing cost is naturally lower than that of ordinary aircraft. This is also the reason why the brothers were able to build this prototype with limited funds.

A few hours later, this strange-looking plane was roaring and taxiing on the runway under the control of the test pilot, then it took off into the sky, flew a few circles in the air, and then landed again.

But it was at this time that an accident happened.

In the airport control tower, the radar operator looked at the screen and said with some confusion:

"Boss, did the plane that just took off take off? I didn't see him!"

There was no sign of the plane on the radar screen, which made the radar operator a little confused, and the person in charge of the control tower said:

"The plane is flying in the sky! How can you not see it?"

As he spoke, he looked out the window - a strange-looking plane was flying in the sky.

The radar operator carefully observed the screen. His brows were furrowed as he stared at the signal on the screen and said:
"Strange, it's not on the radar screen? Where did it go? Could it be invisible?"
