Black technology: I have a refitting factory

The second-generation machine, the third-generation machine, and even the latest model, the arrival of Mr. Huo, Mr. Sun and his party did not comment too much.

Speaking of which, this is a very normal thing.

For aircraft research, breakthroughs are recorded in five or ten years. There have been no major breakthroughs in turboprop aircraft recently, and there may be some progress in small details, but it is difficult to see from the appearance.

Mr. Huo and his team led the team here, mainly not to visit these planes, but to sit down and exchange technology with the two research institutes.

"Mr. Huo, Mr. Sun, shall we start the real test?"

After the experts watched all the planes, Zhao Liming smiled and looked at the two old men in charge.

"let's start!"

Elder Sun nodded.

Zhao Liming hurriedly made arrangements.

"Dear audience, the aircraft flight exhibition of this aviation exhibition is about to begin. Please do not step into the forbidden area, and observe the exhibition in a civilized manner to avoid accidents. This flight exhibition is divided into three parts. The first part, the speed test, will lead You will show the changes in speed during the development of the propeller aircraft, so that you can have an intuitive understanding of the development of the aircraft.

The second part, the display of heavy-duty fuel consumption, will show the fuel consumption ratio of each generation of aircraft..."

A slightly formulaic female voice sounded in the exhibition hall.

With the sound of this sound, all the doors to the take-off pad in the exhibition hall were opened.

The various generations of aircraft placed in the exhibition hall, driven by the traction rope, slowly slid out of the exhibition hall to the take-off pad.

The pilots who had been waiting on the takeoff pad walked towards their respective planes.

"My fellow water lovers, the plane is about to take off! Such a good booth, you can tell me if it's worth the gift money!!"

Qian Qian shouted a little excitedly, it was the first time he saw this scene in so many years.

Watching it live is completely different from watching it on TV.

Especially those latest aircrafts, simply shocking!

As for the plane modified by Su Qi, the wings are comparable, and it is only the wings. In other aspects, it is impossible to compare!

This time the live show is done! !

On the other side, as the pilots all got on board, the planes began to roll out in sequence.

The first-generation machine, as a benchmark, is naturally a take-off.

The first-generation aircraft taxis to the takeoff runway, after everything is ready.

hum!

hum!

hum!

The propellers on both sides of the wing began to rotate slowly, and the wind blew out from the propellers and brought a piece of sand and stones from the ground. The aircraft moves forward quickly, and after reaching a certain speed, it quickly starts to pull up and take off.

"The take-off power is a little stronger than I expected. The designer of this wing is very spiritual! It's a pity that this test can't test the impact of the wing at high speed."

Mr. Huo looked up at the first-generation machine that had already ascended to the sky, and couldn't help but praise it.

Elder Sun nodded, agreeing with Elder Huo.

From the moment of take-off, the modified wings used by the first-generation aircraft have made up for the shortcomings of the supercritical wings as they speculated, and there is not much loss of lift during take-off.

However, they are concerned about another point, whether the biggest advantage of the supercritical wing is affected.

That is, can the shock wave on the wing be reduced at high speed, so as to reduce power loss and keep the aircraft flying stably!

At this point, they speculate that there is a high probability that there is no problem. The real result will not be known until you try it.

It’s just that the size of the first-generation aircraft is too small, and the speed cannot be increased. In other words, because the size of the engine is too small, even if it is equipped with the most advanced engine, the power it can generate is not enough to allow the first-generation aircraft to fly and generate a large number of shock waves. speed.

So there is no way to test how this wing responds to shock waves when flying at high speed.

"Old Huo..."

Just when Old Sun turned his head and wanted to say something, he found that Old Huo's expression changed, pointing to the sky, "Old Sun, that plane..."

"What happened to the plane?"

Seeing Mr. Huo's abnormal performance, Mr. Sun turned his head to look at the sky, then shrank his eyes and showed an incredible expression on his face.

The speed of the first-generation aircraft seems to be approaching the speed of generating a large number of shock waves.

How can it be? !

The two looked at each other, wondering whether they were dazzled.

After all, the two of them were estimating the speed based on the experience of the naked eye, so there might still be problems. However, the volume of the first-generation machine can reach the speed of generating a large number of shock waves, and this possibility is about zero.

Neither of them spoke again, and both looked at the ground at the same time.

To verify whether the two people are dazzled, it is very simple, just add a reference object.

The second-generation aircraft that is taking off is a good example, and its flight speed can be used as a reference.

As the second-generation plane slowly drove to the take-off runway, Huo Lao and Sun Lao became even more concerned.

Soon, the second-generation aircraft took off from the runway, jumped into the air, and flew after the first-generation aircraft.

only……

After flying into the sky, I found that the distance between the two planes did not shrink, but instead widened.

"Old Sun, maybe we didn't see things well..."

Huo Lao took a deep breath.

"How did you do it?"

Elder Sun grabbed his beard and thought about it, then quickly looked at Zhao Liming who was beside him,

"Xiao Zhao, has the engine of this generation aircraft been modified?"

"Why didn't you tell me about such a big change?"

Faced with Sun Lao's questioning, Zhao Liming was completely dumbfounded at the moment, and he naturally knew what was going on.

It's just, who the hell knows that a refitting factory can play such a trick? !

The wings were changed, as was the engine.

Is it something that a refitting factory can do? !

"Mr. Sun, Mr. Huo, if it is said that this plane was not refitted by our China Southern Airlines Research Institute, but by a refitting factory, would you believe it?"

Zhao Liming looked at the two with a mournful face.

"Do you think the two of us look like idiots?"

Old Sun and Old Huo twitched their mouths when they heard this.

"I really didn't lie..."

Zhao Liming is numb all over, no one will believe the truth these days.

He thought for a while, if someone said what he said just now, he would have to say it too!

It's not a good reason to lie.

But it's true!

Seeing Zhao Liming's expression of wanting to cry but no tears, Elder Sun and Elder Huo looked at each other, knowing in their hearts that it was probably the truth.

It's just that it's still a bit unbelievable that a refitting factory actually refitted such an aircraft.

Outrageous!

Elder Sun looked at the first-generation aircraft flying in the sky, thought for a while and suddenly said,

"Old Huo, it may not be as outrageous as you and I think. Maybe the two engines are a bit more eccentric, consume more fuel, and use airflow to drive a greater speed. This one can also reach this speed."

"Hmm!" Mr. Huo pondered for a while when he heard the words, and then replied,

"Wait until you look at the fuel consumption and you will know. There is a high probability that it is the situation you mentioned."

The two of them calmed down a little.

For the turboprop aircraft to be studied, the speed is increased in one direction, but it is not the most critical. Fuel consumption and load are the most important considerations.

Although the first-generation machine in front of me is fast, it should be achieved at the expense of fuel consumption.

This is a bit outweighed.
