Invisible in the eyes, this is limited to those science fiction movies. Whether it is the people on the Diaoyu River or the people on the destroyers of the island country, although they have thought that the Celestial Empire already has such advanced stealth technology fighter jets, it is just a thought. After all, such technology is at least decades ahead of today, and they do not think that the Celestial Empire has the ability to develop it.

No matter how they guess, outsiders will definitely not know that "Shadow Dragon One" has such a function in a short period of time, because at the beginning, the technology of the drone has always been in a top secret state. Even if the drone officially faces the eyes of people all over the world, this function will be secretly announced.

Xu Ziling, who controls the return of the drone, is in an extremely good mood now.

It took a sweep of the depression of the busy and exhausted months and the failure to track down the news of the ambush of the Sword Squad in the Middle East.

Recently, the Celestial Empire fell into the sea area in the East China Sea and marked the flight identification area. Shortly after the issuance of this doctrine, the Mid-Army and the island countries announced that they would not recognize it, thus arrogantly sending fighter jets to fly in this airspace.

At that time, the drone had not been created yet. Faced with these two countries, the Celestial Empire had no ability to deal with it at the same time. It could only be seen that these guys were arrogant there.

Being able to get two F-15s today can be regarded as avenging the revenge that has been depressed for a while.

I wonder if the islanders think they have seen a ghost?

Thinking of the suspicion that they heard the sound but did not see the fighter plane, Xu Ziling thought of gloating.

"What happened today will be top secret. You guys remember to keep your mouth in mind, even the closest people around you can't say it, do you know?"

If the matter is leaked, it will not only be caused by the island country, but once this sharp killing weapon is made public, you will also know how many countries will face their own methods and the seriousness of the matter. Even if you know that among the younger generation, you are either a soldier or have close ties with the military headquarters, you will understand these, but Yang Haisheng still seriously reminded Lin Jianbin and Liu Long and other juniors once.

"Yeah, I understand."

"knew."

Although they are still young, their environment allows them to know how powerful they are. No one is disgusted with Yang Haisheng's harshness, and they all honestly responded.

"I can't say it now, but when you get old, it's a pride to show it in front of your descendants and grandchildren. But if you think about us old guys, you probably won't have this chance."

Mr. Huang looked at them and said with a smile.

Such things that can't be said about the things that increase your face are like having happiness in your heart but not sharing them with others. It is indeed a depressing thing.

With such feelings, the few people felt a little uncomfortable, but after hearing Mr. Huang's words, everyone's eyes immediately lit up and thought this idea was really good.

Think about what the scene would be like when I was old and had a lot of children and grandchildren, and I could tell the miracles I had witnessed in front of a group of juniors?

"Haha... You are not the same as you always say. You are only in your sixties this year. This kind of thing will probably be deciphered in thirty years. You can say something in front of your great-grandson at that time."

Xu Ziling listened aside and took over the conversation.

"hehe……"

"Zi Ling is really right."

As soon as he said that, everyone laughed and nodded.

"You boy said this, it's really possible. It seems that for this glory, I must live at that time."

Mr. Huang felt that things were really like this. His physical condition is pretty good now. Maybe it’s okay to live until then.

"It seems that we old guys still have to work hard to live."

Mr. Li also laughed and started joking.

~~~~~~~~~~~~~~~~

A few dozen minutes later, the drone returned.

As soon as they entered the hangar, many ground crew members began to conduct comprehensive inspections of the aircraft.

Because Xu Ziling had to communicate with Captain Zhang when he happened, no one greeted him. If he had something to do, he would go to the hangar to see the drone.

Until evening, all the staff had a dinner at the restaurant in the military factory, which was to celebrate the completion of the drone test.

The test was completed, but during this period, Xu Ziling had other things in his hands. He did not use the drone weapon himself, but asked the lion to come up with a plan and hand it over to the people below.

The thing that keeps him busy is the "Flying Eagle" fighter project.

The "Flying Eagle" fighter is a solution optimized from the f-22. In terms of appearance, it is not much different from the f-22.

The double-sided tail double-engine single-seat layout is also adopted. Unlike the original, its vertical tail is not tilted outward by 27 degrees, but is slightly reduced, making its stealth effect better.

The air intake is distributed on both sides and is installed below the extension surface of the wing's leading edge, which only improves the invisible design to suppress infrared radiation. The main wing and the back of the fuselage adopt the same sweep angle and the trailing edge sweep angle, both are trapezoidal planes with small aspect ratio.

In addition, the cockpit. The water droplet-shaped canopy cover made of a new high-strength transparent material protrudes from the front fuselage, which is more suitable for aerodynamics than the f-22's own cockpit design, as well as more safety, comfort and stealth.

On the "Flying Eagle", what is more worth mentioning is the tail nozzle, the two tail nozzles, which are made of the latest tungsten alloy material. Unlike the general design method of trying to hide the nozzle as much as possible, it is instead reversed, exposing the nozzle long behind the fuselage.

The reason why the tail nozzle is designed like this is because it can make it move perfectly, and the tail nozzle is moving.

Unlike ordinary fighter jets, the nozzles are generally inactive, but above the "Flying Eagle", the tail nozzle can perfectly rotate 360 ​​degrees on the front.

This design uses a brand new thrust vector technology, which uses the perfect change direction of the vector tail nozzle to control the reverse thrust generated in different directions of the jet flow during the engine operation, to quickly change the direction of the aircraft, thereby greatly increasing the maneuverability of the aircraft.

However, such a design has a big problem for others, that is, the tail nozzle invisibility.

The tail nozzle of a fighter is different from that of a passenger plane. Because of the bypass ratio, when the fighter's tail nozzle is flying, at least half of the airflow emitted by the engine is the blazing flame emitted by the combustion chamber.

This flame carries absolute high temperatures, which is just like radars such as infrared and thermal detection. And there is no stealth material in the world that can reach this high temperature.

But because of the lion, this problem is not a problem here.

Not to mention that there are related invisible materials in its system, the complete machine solution originally contains the formula and production process of this material.

Although the production process is relatively advanced, it is still fine to mass production after working hard.

In the past few months, Xu Ziling has been busy with the "Flying Eagle" project in addition to being busy with drones.

According to the data in the plan, the Flying Eagle fighter has a total length of 18 meters, a wing length of 13 meters, a height of 5 meters, an empty load of 15 tons, and a maximum take-off weight of 45 tons.

In terms of speed, its maximum speed can reach Mach 3.5. The range can fly 4,000 kilometers without the secondary fuel tank when the aircraft is unloaded and does not have a secondary fuel tank. The full load combat radius is 1,500 kilometers.

However, due to the use of vertical take-off and landing technology, the "Flying Eagle" fighter can land and refuel at any airport, which greatly increases its combat maneuverability.

Originally, according to Xu Ziling's idea, he just wanted to create a brand new carrier-based fighter, but according to the data of the "Flying Eagle" fighter, it can be regarded as a multi-purpose fighter.

Although stealth performance cannot be compared with Shadow Dragon drone, it can definitely ensure that the American fighter will not be discovered 20 kilometers away.

The maximum take-off weight of 45 tons means that it can carry a large number of missiles like a bomber to carry out bombing missions to targets.

In addition, the upgraded version of the "Hawkeye System" has the functions of reconnaissance and electronic warfare. It can block electronic signals from places on a large scale, and can also detect enemy ground intelligence.

Sometimes Xu Ziling also thinks that once this model comes out, there is probably no chance of fighting that will be its opponent.

Imagine the days when the sky is dominating, and he is very excited.

On that day, he was dealing with some things about the "Flying Eagle" project in the laboratory, and the phone suddenly rang.

"What? How could this happen?"

He picked up the phone and the news he received made him exclaim.

The phone call was from his father Xu Haoran and told him an amazing news: a leak occurred in the technical exchange department that had been established for only a few months, and all relevant technical information was copied.

"Have you caught it?"

"No, the person was a person in charge sent by the ** Research Institute. When the technician found out that the information was copied, the incident had happened for several hours, and the other party had already left the country."

"Oh, let's talk about it when I go over."

On the phone, Xu Ziling didn't want to say much, so he hung up the phone quickly, left the laboratory and went to Xu Haoran's office.

He was not in a hurry to see that technical data was leaked. As a result, although some of those technologies were ahead of today's level, he had better ones and was not worried that the technology would have too much impact on himself and the country after it was leaked.

Secondly, he also had a back-up. When he established this institution, he considered the issue of leaks. Although he was not responsible for the management of the here, he carried a very small procedure in the information he handed over.

The function of this program is to verify the user's identity and a dedicated computer when the information is opened. Once the information is run on other computers, it will all become a bunch of garbled code.

When the institution was established, the relevant security measures required that each institute must have a dedicated computer. I believe that the person in charge of the defection was only a simple method, and I thought it could be cracked. If he tried to open it on another phone, he would know that no matter what method he used to crack it, it would not be successful.
Chapter completed!
