The fifth-generation stealth fighter is nothing more than those few characteristics, stealth, supersonic cruise, and thrust vectoring.

This small plane performs very well on the stealth, and after the length of 3.5 meters is reflected on the radar, only 2.1 meters remain.

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

The second is supersonic cruise, which Yan Hang is not sure about, but according to the current engine data, it is better than the performance of the Raptors anyway.

The third is thrust vectoring, which is not very easy to do, but the difficulty of this is a bit large, which can be said to be a redefinition of the engine.

But in terms of invisibility alone, that's pretty remarkable.

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

The only thing that makes him feel sorry is that the plane that appears in front of him now is too small.

If it can reach about seven meters, then his company's Sword UAV has an unmanned fighter that can be used for escort so far.

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

Thinking of this, he sighed slightly.

Thinking like this, to drive these thoughts out of his mind, let's focus on the present, he is really interested in the small plane that Li Zhenhua made.

Looking at the young man sitting on the side, harmless to humans and animals, who would have thought that the other party would make such a fierce plane just by playing?

Arrived here first, Yan Hang thought of a different control method from conventional drones.

Ordinary UAVs will not use such a realistic cockpit, which makes people feel that they are really piloting a fighter.

But it is precisely this kind of realistic cockpit that he uses, which makes him a little difficult to understand, why not use the mainstream control method?

"Zhenhua, what do you think, why do you use the realistic cockpit in the control mode,

Why didn't you use the control method like a 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 it was better to manipulate it realistically.

"Old man, I really didn't think about this question before,

But now if I had to choose, I would still choose this way.

Because this allows the pilot to use his or her full potential.

Some barrel rolling or something, if you use a non-moving perspective, the pilot does not intuitively feel,

I'm a drone, it's not a drone, it's just that my pilot doesn't fly it. ”

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

Yan Hang also has a positive attitude towards his idea, and highly maneuverable fighters should be piloted in this way.

"There's also a question, how do you solve the data transfer between the aircraft and the console, which 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, being able to be limited to the civilian field, and no satellite was solved with only 5G, which was really a spare head.

But then he thought that the coverage of 5G is not large, generally within 500 meters, and he can't figure out this problem.

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

You have to know that height, 5G can't receive a signal,

The base station doesn't have that much coverage. ”

He didn't expect the other party to notice this problem at all, and since the plane landed at the base and rose to an altitude of 10,000 meters, no one noticed this problem.

How did he solve this problem? It took him a month of real-life nights in a virtual lab to finally solve the problem.

"This issue is very complicated, and it is not something that I can explain clearly in one sentence or two.

Anyway, by combining the three technologies of 3G, 4G, and 5G, the last effect I get is 26,000 meters.

Moreover, the nose position of the small aircraft has an integrated launch base station inside. ”

Yan Hang didn't understand his explanation, because what the other party said was very general.

Listening to such an answer, he also knew that the other party didn't want to answer this question, so Yan Hang didn't ask.

He also looked at Cui Tianzhi after a general reply.

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

He couldn't help but be a little worried and confirmed it again, and Cui Tianzhi also patiently told him again.

"Xiao Li, so far, your solution is to pay a fine of 100,000 yuan, and the rest of the things need our leaders above to make up their minds, but with me and Zhengwei guaranteeing you, the problem behind is not big!"

Hearing the exact answer again, he was completely relieved.

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

Then Yan Hang, under the leadership of Cui Tianzhi, came to the hangar to see the small plane, and Li Zhenhua also followed this time.

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

Yan Hang circled around the small plane several times, and from his professional point of view, he found that this plane was so exquisitely designed.

And he couldn't find anything to modify on the plane, which also surprised him.

The plane and the cockpit were looked at together, and the sun was about to set in the distance.

A few people actually brought another afternoon in the hangar, and after seeing the small plane, Yan Hang muttered a sentence in his mouth when he was about to walk out of the hangar.

"Alas, it's a pity, all aspects are eligible, but the plane is a little small in size!"

Yan Hang originally meant to say a word to himself, but Li Zhenhua, who was following behind, listened to it.

And when he listens to this, he is thinking about something else in his heart,

After hearing this emotion, his brain did not function, and his subconscious said a word.

"Too small? I've got a big one! ”

As soon as he said this, he began to come back to his senses.

Thinking back to what he had just said, he felt his hairs stand on end.

And Yan Hang was talking to himself, but he really didn't think that anyone would pick up the stubble, and the person who took over was Li Zhenhua.

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

But it was precisely because he knew what it meant that he looked at Li Zhenhua with some eyes like he was looking at a fairy.

And just when Yan Hang reacted, everyone present also heard his words.

And at this moment, Cui Tianzhi's reaction is one, this is endless, not counting small planes, there are actually bigger ones?

People who had never known anything about this before, and who had the same reaction as him, were also focusing their eyes on him.

Yan Hang, who finally reacted, turned his head and said to him solemnly.

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

Where? Did you build a bigger one than this little 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 has said that there is a bigger one, that is, there is a bigger one.

He was surrounded by the crowd, and all eyes were on him.

He finally couldn't stand everyone's gaze, and answered this question opposite Yan Hang.

"That~, I~, um~"

I didn't say a word when I was deflated, all of them were such words.

Yan Hang was also anxious, and continued to ask him.

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

Say it quickly, say it early and relax early,

You don't have to live with a big rock in your heart all day long! ”

I feel that what Yan Hang said is really like that, this 3.5-meter one can cause trouble, and the eight-meter one can't cause more things?

Unless he has amnesia from now on and forgets all about that plane! Otherwise, with his character,

I don't know when, I will secretly assemble an eight-meter plane.

After figuring out the key thing, he gritted his teeth and said the matter!

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

Speaking of which, he listened to it for a while, let the other party digest the information, and then when they talked again, it was not in this state.

It's in a way of showing off, talking to a few people, completely forgetting everything at the moment.

"If you want to say that this plane has something to say, the one I just saw, which I shrunk on the basis of that eight-meter model airplane,

In other words, the first ones are the big ones, and then the small ones. ”

Arabian Nights, nonsense, bizarre... These are the words that came to the hearts of all present,

No one wanted to believe that what he said was true, and everyone was a person who had been through the wind and waves, and they all kept calm.

Cui Tianzhi couldn't help but ask: "That is to say, you got an eight-meter-long plane, and then made a small plane on the basis of it, I understand it correctly, right?"

But why make a small one when you've already made a big one? I don't understand that. ”

Yan Hang solved his question after Cui Tianzhi asked.

"It must have been that he also noticed that the eight-meter plane was too outrageous, so he made the small plane out in order to be able to fly into the sky, am I right!"

looked at Yan Hang, who was right about the mystery, he was really right by him.

"Hey, hey, hey, it's actually nothing, it's just when I got it,

I also felt that I was holding up too much, so I got a small plane with a length of only 3.5 meters.

Old man, you have to know that an eight-meter-sized plane really looks like a fighter jet, so there must be more misunderstandings.

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

Everyone present held up a big female finger at him in unison.
