Chapter 142 Big one

Fifth-generation stealth fighters are nothing more than a few features: stealth, supersonic cruise, and thrust vectoring.

This small aircraft performs very well in terms of stealth; its 3.5-meter length is reflected onto radar, leaving only 2.1 meters.

It's important to understand that this only refers to the stealth of the aircraft's external structure. If it were coated with stealth paint, the stealth effect would certainly be even better.

The second is supersonic cruise. Yan Hang is not sure about this yet, but based on the current engine data, it is better than the Raptor's performance.

The third is thrust vectoring, which is not easy to achieve. It is quite difficult and can be said to redefine the engine.

But just in terms of invisibility, this is already quite remarkable.

Thinking of all this, Yan Hang immediately remembered one of the models in his factory - the Sharp Sword unmanned combat aerial vehicle.

The only thing that bothered him was that the plane standing in front of him was too small.

If it can reach about seven meters, then his company's Sharp Sword drone will have an unmanned combat aircraft that can be used for escort missions.

This would undoubtedly greatly increase the probability of his unmanned combat aerial vehicles surviving before reaching the battlefield.

Thinking about all this, I let out a soft sigh.

Thinking this through, he banished these thoughts from his mind and focused on the present. He was genuinely interested in the small airplane that Li Zhenhua had created.

Looking at the seemingly harmless young man sitting to the side, who would have thought that he had just been playing around and managed to build such a powerful airplane?

That's all for now. Yan Hang then thought of the differences in the control methods used compared to conventional drones.

Most drones don't use such realistic cockpits, making users feel like they're actually piloting a fighter jet.

But he used this kind of realistic control cockpit, which made it hard for him to understand why he didn't use the mainstream control method.

"Zhenhua, what were you thinking? Why did you use a simulated cockpit for the controls?"

Why didn't they use a control method like the Global Hawk?

Li Zhenhua hadn't really thought about Yan Hang's question, but after being reminded by him, he thought about it and felt that the simulated control method was better.

"Grandpa, I really hadn't considered the issue you raised before."

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

This allows the pilot to reach their full potential.

Some actions, like barrel rolling, cannot be perceived by the pilot if viewed from a stationary perspective.

This is a drone, but it's not really a drone; it's just that my pilot isn't in an airplane flying it.

Li Zhenhua explained his understanding to Yan Hang, who nodded in agreement.

Yan Hang also agreed with his idea, believing that highly maneuverable fighter jets should be piloted in this way.

"Another question is how you solved the data transmission problem between the aircraft and the control panel. That's a major challenge."

"I'm using a 5G network, and my information transmission system consists of many IoT SIM cards!"

Yan Hang was quite impressed at this point. Being able to limit it to the civilian sector and solve the problem using only 5G without satellites was truly ingenious.

But then he realized that 5G coverage is not very wide, generally within 500 meters, and he couldn't understand why.

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

At that altitude, 5G signals won't be received.

No base station has that much coverage.

He never expected that the other party would notice this problem. From the moment the plane landed at the base until it ascended to an altitude of 10,000 meters, no one had noticed it.

How did he solve this problem? He actually spent a whole month flying in a virtual lab, equivalent to nighttime in real life, before finally solving it.

"This is a very complex issue, and it's not something I can explain in just a few words."

Basically, by combining 3G, 4G, and 5G technologies, I achieved this effect, with a maximum transmission distance of 2.6 meters.

Furthermore, there is a comprehensive launch base station inside the nose of the small aircraft.

Yan Hang didn't understand his explanation because it was too vague.

Hearing this answer, he knew that the other party did not want to answer the question, so Yan Hang stopped asking.

After giving a general reply, he looked at Cui Tianzhi.

"Sir, is my question about whether everything will be fine once I pay the fine?"

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

"Xiao Li, for now, your solution is to pay a fine of 100,000 yuan. As for the rest, that depends on our superiors. But with Zhengwei and me guaranteeing it, there shouldn't be any major problems later!"

Hearing a definite answer again, he was completely relieved.

Yan Hang chatted with the two leaders at the base. He took his phone, which was now back in his hand, and called Li Yun to let her know he was safe.

Later, Yan Hang, led by Cui Tianzhi, went to the hangar to see the small planes, and Li Zhenhua also came along this time.

He also saw the model airplane again, which had been properly maintained by the ground crew.

Yan Hang circled the small plane several times. From his professional perspective, he finally realized how exquisitely designed the aircraft was.

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

I looked around the plane, including the cockpit, and by then the sun was about to set in the distance.

The group ended up spending another afternoon in the hangar, looking at the small planes. As Yan Hang was about to leave the hangar, he muttered something to himself.

"Sigh, what a pity. It meets all the requirements except that the plane is a bit too small!"

Yan Hang meant it as a remark to himself, but Li Zhenhua, who was following behind, overheard it.

Moreover, while he was listening to this, his mind was wandering to other things.

Upon hearing this remark, his brain seemed to shut down, and he subconsciously uttered a response.

"Too small? I have bigger ones!"

As soon as he said those words, he began to come to his senses.

As he carefully recalled what he had just said, he immediately felt a chill run down his spine.

Yan Hang was just talking to himself, but he never expected anyone to respond, especially Li Zhenhua.

Yan Hang heard his words clearly and understood their literal meaning.

But precisely because he knew what it meant, he looked at Li Zhenhua with an expression that was almost like looking at a deity.

Just as Yan Hang came to his senses, everyone present heard his words.

At this moment, Cui Tianzhi's reaction was, "Is this ever going to end? Not only are there small planes, but there are even bigger ones."

This was someone they had never heard of before, and people who had the same reaction as him were also focusing their attention on him.

Finally realizing what was happening, Yan Hang turned to him and said seriously.

"What did you just say? There's something even bigger?"

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

Yan Hang was completely convinced that he would actually build an even bigger one, because Li Zhenhua's initial impression of him was that of someone who was good at creating miracles.

Now that the other party says there's an even bigger one, then there must be an even bigger one.

He was surrounded by a crowd, with all eyes on him.

He finally couldn't withstand everyone's gaze and answered the question directly opposite Yan Hang.

"Um... I... um..."

He stammered and couldn't utter a single word, only managing mumbled "uh-huh" and "ah-ah" sounds.

Yan Hang was also an impatient person, and continued to ask him questions.

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

Hurry up and say it, the sooner you say it, the easier it will be.

You don't have to live with a huge weight on your mind all the time!

It seems Yan Hang's words are quite true. If a 3.5-meter aircraft can cause trouble, what would an 8-meter aircraft cause?

Unless he suddenly loses his memory and forgets everything about that plane, given his personality...

They'll probably secretly assemble an eight-meter airplane sometime later.

Having figured out the key point, he gritted his teeth and told him what had happened!

"That old man, President Gu, and Chief Cui, I did get a bigger one, but I haven't installed it yet."

He listened for a moment, allowing the other person to process the information, and then the conversation shifted completely.

Instead, he was showing off to a few people, completely forgetting everything else at the moment.

"There's a lot to say about this plane. The one we just saw was a scaled-down version of that eight-meter model airplane."

In other words, the larger one came first, and then the smaller one followed.

Fantasy, absurd, bizarre... these were the words that came to mind for everyone present.

No one wanted to believe that what he said was true. Everyone present was a seasoned person who had weathered many storms, and they all remained relatively calm.

Cui Tianzhi couldn't help but ask, "So you mean you built an eight-meter-long airplane, and then based on that, you built a smaller airplane? Am I right?"

But since you've already built a big one, why build a smaller one? I don't understand.

Yan Hang, however, resolved Cui Tianzhi's doubts immediately after he asked the question.

"He must have realized that the eight-meter plane was too outrageous, so he brought out the smaller plane in order to get it airborne. Am I right?"

Looking at Yan Hang, who had just answered the riddle correctly, he realized that Yan Hang had indeed guessed right.

"Hehehe, it's nothing really, it's just that when I made it..."

I also felt that I had overestimated myself, so I made a small airplane that was only 3.5 meters long.

Old man, you have to understand, an eight-meter-long airplane really does look like a fighter jet, which would only lead to more misunderstandings.

That's when the small plane came in handy, but I never expected it to be such a powerful machine! Its performance was incredibly strong.

Everyone present gave him a thumbs up.
