The fifth-generation stealth fighter has only a few characteristics, including stealth, supersonic cruise, and thrust vectoring.

This small aircraft performs very well in stealth. After the length of 3.5 meters is reflected on the radar, only 2.1 meters remain.

You must know that this is just the invisible appearance and structure of the aircraft. If it is coated with invisible paint, the invisible effect will definitely be better.

The second one is supersonic cruise. Yan Hang is still not sure about this, but judging from the current engine data, it is better than the Raptors anyway.

The third is thrust vector. This is not easy to achieve. This is quite difficult. It can be said to be a redefinition of the engine.

But in terms of invisibility alone, this is already amazing.

Thinking of this, Yan Hang immediately thought of a model in his factory - the Sword unmanned attack aircraft.

The only thing that made him feel regretful was that the plane that appeared in front of him was too small.

If it can reach about seven meters, then his company's Sharp Sword drone will be the only unmanned fighter that can be used for escort.

This will undoubtedly greatly increase the survival probability of his unmanned attack aircraft before reaching the battlefield.

Thinking of this, he sighed slightly.

Thinking like this, he pushed these thoughts out of his mind and focused on the present. He was really interested in the small plane made by Li Zhenhua.

Looking at the harmless young man sitting on the side, who would have thought that he could build such a powerful plane just for fun?

Arriving here first, Yan Hang thought about the differences in the control methods used with conventional drones.

Ordinary drones will not use such a realistic cockpit, which makes people feel like they are actually flying a fighter plane.

But he used exactly this kind of realistic control cockpit, which made it a little difficult for him to understand, why not use the mainstream control method?

"Zhenhua, what do you think? Why do you use a realistic cockpit for control?

Why don’t you use the control method like Global Hawk?”

Li Zhenhua really hadn't thought about Yan Hang's question, but after being reminded by the other party, he thought about it and felt that realistic control would be better.

"Old man, I really didn't think about this issue you mentioned before.

But now let me choose, I will still choose this method,

Because this can use the pilot's maximum potential,

Some barrel rolls and other movements, if the perspective is not used, the pilot will not have an intuitive feeling.

This is a drone, not a drone, but my pilot is not on the plane. "

Li Zhenhua explained his understanding to Yan Hang one by one, and the other party nodded in agreement.

Yan Hang also holds a positive attitude towards his idea. Highly maneuverable fighter jets should be flown in this way.

"I still have a question. How do you solve the problem of data transmission between the aircraft and the control console? This is a big problem."

"The 5G network I use, many IoT cards form my information transmission system!"

Yan Hang was a little impressed at this time. It was able to be limited to the civilian field, and there were no satellites and it could be solved with only 5G. It was really a piece of work.

But then he thought that the coverage range of 5G was not large, generally within 500 meters. He couldn't figure out this problem.

"So how do you solve the problem of information transmission system in the air at a height of 10,000 meters?

You need to know that at that height, 5G cannot receive signals.

No base station has such a large coverage area. "

He didn't expect that the other party would notice this problem at all. From the time the plane landed at the base until it rose to an altitude of 10,000 meters, no one noticed this problem.

How did he solve this problem? He spent a month flying in the virtual laboratory and at night in real life before he finally solved this problem.

“This issue is very complicated, and I can’t explain it clearly in just one or two sentences.

Anyway, this is the effect I finally got by combining the three technologies of 3G, 4G, and 5G. The longest transmission distance is 26,000 meters.

Moreover, there is a comprehensive transmitting base station inside the nose of the small plane. "

Yan Hang didn't understand his explanation because the other person spoke in very general terms.

Listening to this answer, he also knew that the other party didn't want to answer this question yet, so Yan Hang stopped asking.

He also gave a general reply before looking at Cui Tianzhi.

"Chief, my question is, as long as you pay the fine later, it won't be a big deal?"

He couldn't help but confirm it again with some worry, and Cui Tianzhi patiently explained it to him again.

"Xiao Li, your solution so far is to pay a fine of 100,000 yuan. For other things, our leaders need to make up their minds. But with Zhengwei and I guaranteeing you, there won't be any big problems later!"

Hearing the exact answer again, he was completely relieved.

Yan Hang chatted with the two leaders of the base. He took the mobile phone back to his hand and called Li Yun to report that he was safe.

Then Yan Hang, led by Cui Tianzhi, came to the hangar to see the small aircraft, and Li Zhenhua also followed this time.

He also saw again the model aircraft that had been maintained by the ground crew.

Yan Hang circled the small plane several times. Looking at it from his professional perspective, he realized that the plane was so exquisitely designed.

And he couldn't find anything that could be modified on the plane, which also surprised him.

I looked at the plane and the cockpit together. At this time, the sun in the distance was about to set.

Several people actually spent an entire afternoon in the hangar. After watching the small plane, Yan Hang muttered something in his mouth when he was about to walk out of the hangar.

"Oh, what a pity. Everything meets the conditions, but the plane is a bit small in size!"

Yan Hang originally meant what he said to himself, but Li Zhenhua, who was following behind, listened.

And while he was listening to this, he was thinking about other things in his mind,

After hearing this sigh, his brain didn't work, and his subconscious said something.

"Too small? I have a big one!"

Just as he said these words, he began to come back to his senses.

Thinking carefully about what he had just said, he immediately felt his hair standing on end.

And Yan Hang was talking to himself, but he really didn't expect anyone to pick up the slack, and the person to pick up the slack was Li Zhenhua.

Yan Hang heard his words clearly, and he also understood what they meant literally.

But precisely because he knew what it meant, he looked at Li Zhenhua as if he were looking at a god.

And just when Yan Hang reacted, everyone present also heard what he said.

At this moment, Cui Tianzhi's reaction was one, this is not over yet, not counting small planes, but there are actually bigger ones?

This was someone I had never known before. People who had the same reaction as him also focused their attention on him.

Yan Hang finally reacted and turned to him seriously.

"What did you just say? Is there something bigger?

Where is it? Did you build a bigger one besides this small plane? "

Yan Hang fully believed that he would really build a bigger one, because Li Zhenhua gave him the feeling from the beginning that he was the kind of person who was good at creating miracles.

Now that the other party said there is a bigger one, that means there is a bigger one.

Surrounded by everyone, all eyes were looking at him.

He finally couldn't stand the attention of everyone and answered this question opposite Yan Hang.

"Um~, I~, um~"

I couldn't say a word. They were all words like um um ah ah ah

Yan Hang was also impatient and continued to ask him.

"Okay, just say it. It's better to say it now than later.

Say it quickly, say it earlier and it will be easier,

You don’t have to live with a big stone in your heart all day long! "

It feels like what Yan Hang said is true. This 3.5-meter one can cause trouble, but the eight-meter one can cause more trouble?

Unless he loses his memory from now on and forgets all about that plane! Otherwise, given his character,

I definitely don’t know when the eight-meter aircraft will be assembled secretly.

After figuring out the key things, he gritted his teeth and told the story!

"The old man, Mr. Gu, and Chief Cui are in position. I did get a bigger one, but I haven't assembled it yet."

After saying this, he listened for a while and let the other party digest the information. When they started chatting again, it was not in this state.

Instead, he was talking to a few people in a show-off way, completely forgetting everything at the moment.

"If you want to talk about this aircraft, there are many. The one I just saw was a scaled down version of my eight-meter model aircraft.

In other words, the big one comes first, and then the small one. "

Fantasy, nonsense, bizarre... These are the words that popped up in the minds of everyone present.

No one wanted to believe that what he said was true. Everyone had gone through great storms and still remained calm.

Cui Tianzhi couldn't help but asked: "In other words, you built an eight-meter-long plane, and then built a small plane based on it. I understand this right, right?

But since you have already made a big one, why do you want to make a small one? I can't understand this. "

However, after Cui Tianzhi asked, Yan Hang immediately solved his question.

"He must have realized that the eight-meter plane was too far to land. In order to be able to fly into the sky, he made the small plane. Am I right?"

Looking at Yan Hang who had just figured out the answer to the riddle, he was really right.

"Hehehe, it's actually nothing, just when I got it out,

I also felt that I was overstretched, so I made a small plane with a length of only 3.5 meters.

Old man, you have to know that an eight-meter aircraft really looks like a fighter jet. There will definitely be more misunderstandings like that.

At this time, the small plane came in handy, but I didn't expect that this small plane was also a dragon crossing the river! The performance is actually so strong. "

Everyone present raised a big female finger at him.
