Siheyuan: Rise from Sign-in

Chapter 838 A small upgrade!

The layman looks at the excitement and the insider looks at the doorway.

When Hong Cheng saw that the plane took off in such a short distance, his face was full of surprise.

"Xiao He, this takeoff data is a little different from the original data."

Hong Cheng clearly remembered that according to the original data, the shortest take-off distance of a fighter jet is 450 meters, and when fully loaded, the take-off distance is 650 meters.

But just now, he visually measured the take-off distance of the fighter jet, but it was only about 300 meters, or even shorter. How could such data not surprise him.

"It's different."

He Yuzhu looked at Hong Cheng with admiration in his eyes. As expected of an astronaut of the older generation, his eyes are poisonous.

"Why is this happening? Is there something wrong with the demo data?"

Hong Cheng asked hurriedly.

This is not a joke. If the data is wrong, it would be extremely dangerous for the plane to go to the sky.

"No, Mr. Hong, listen to me, it's like this."

He Yuzhu explained with a smile.

"The reason why the fighter jets you see can take off in such a short distance is because we have made a small upgrade to the engine."

"The thrust of the engine has been increased. Now each engine on the fighter plane can have a maximum thrust of 180 kN, but even the intermediate thrust has reached 140 kN."

"In the original engine, the maximum thrust is only 125 kN, and the middle thrust is only about 76 kN. There is too much difference between the two data."

"The upgraded engine of the former, even without afterburner, has completely exploded the original engine with afterburner only with intermediate thrust."

"Now, it's no surprise that you can take off at such a short distance."

He Yuzhu said it lightly, but these words fell into the ears of Hong Cheng and Bai Haishan's experts, but they made their hearts flutter and their brains crashed.

A small upgrade can improve the performance of an already powerful engine so much, and it is still in such a short period of time.

You know, they got the turbojet engine technology from Big Brother a few years ago. That's it. It took them several years to figure out the engine technology and start independent production.

During this period, they wanted to upgrade and modify the engine more than once, but even they had figured out the technology of the engine.

They want to change, but can't do it.

Even if they made some modifications, in the end, they found that the performance of the engine not only did not improve, but dropped a lot after their modification.

Such a result made Hong Cheng and the others feel extremely disappointed.

In the end, what caused it? In order to upgrade and modify the engine, they were cautious and cautious. It took about a year to justify the matter.

During this period, the formulas they wrote, the drafts of drawings, even filled an office.

But that's it, they still failed in the end.

It is precisely because of this reason that they know how difficult it is to upgrade and transform an engine.

But at this time, they learned from He Yuzhu that the other party had completed the upgrade of an engine in a very short period of time.

How is this possible!

Hong Cheng stared at He Yuzhu with wide eyes.

"Xiao He, is what you just said true?"

"That's right! It's true. If there were no new engines, how could that plane take off in such a short time? It all depends on those two powerful engines."

"And it is true that with those two engines, the maximum speed of that fighter jet can reach Mach 2. Otherwise, the speed of the aircraft can reach Mach 5, and it will be very popular."

There was still some regret on He Yuzhu's face.

If he didn't have more advanced basic material technology in his hands, he could increase the maximum thrust of the engine to 20 tons or even higher.

At that time, the flight speed of the aircraft exceeded Mach 3, and there was no problem at all.

In that case, this fighter is the most powerful fighter.

You must know that the most important way for fighter jets at this time is to rely on machine guns to fight dogs. Although there are already air-to-air missiles, they are limited by radar and fire control technology.

The air-to-air missiles at this time are just like toys, with a maximum distance of less than ten kilometers, plus a touching hit rate.

Most fighter pilots trust their guns more.

But the fighter he produced did not have this problem at all.

Advanced radar and fire control technology, coupled with advanced air-to-air missile technology, have made this fighter jet a crushing existence.

If it is used for combat, it is simply a dimensionality reduction strike for fighter jets of this era.

Even as long as the ammunition is unlimited, no matter how many fighter jets come, it can be shot down.

At this time, a crazy idea even popped up in He Yuzhu's mind, to drive this fighter jet to the north for a stroll.

If you can use this fighter jet produced in the north of the wishing world to shoot down its predecessors, the picture is very exciting to think about.

As soon as such a crazy idea popped up, it took root and sprouted in He Yuzhu's heart like a seed, and it couldn't go away no matter what.

At this time, Hong Chengcai recovered from the shock just now.

Really?

Is it true?

this is too scary.

At this time, Hong Chengcai fully understood how terrifying the opponent's scientific research strength was. Even the north side didn't seem to have such technology.

Not even the beautiful country seems to have one.

After all, as the relationship between Xia Guo and Big Brother cracked, Meiliguo immediately offered an olive branch.

And it was through these relationships that Hong Cheng also had some understanding of the aviation technology of the Western powers. At this time, the main fighter jets of the Western powers had the same engines as their domestic fighter jets at this time. They were all turbojet jets. The engine belongs to the second generation of aero-engine.

That is to say, they are technically a little more advanced than their engines, but the gap is not too big.

But the fighter jet flying in the sky now is powered by a turbofan jet engine, which belongs to the third-generation aeroengine.

The difference between the two is a whole generation.

This technical advantage is not at 01:30.

But that's it, people can upgrade the engine in a short period of time, what a terrifying level of technology reserves this has reached!

It would be great if they could have such a technical reserve!

And Zhao Huaiyuan looked at the shock on the faces of Hong Cheng and the others, and was a little confused.

"Well, Xiao He, what's wrong with them?"

Although Zhao Huaiyuan was the leader of the Ministry of Light Industry, he didn't know anything about aviation technology, and he couldn't imagine that what He Yuzhu said just now would affect an astronaut like Hong Cheng.

What a shock it was.

"It's okay, I was just scared."

Zhao Huaiyuan didn't understand, but He Yuzhu did.

However, not only did he not laugh at this time, but his face was full of respect.

It is because of these older generation of astronauts that they can come from behind and develop their own fighter jets to defend the sky of the motherland.
