The top student must be diligent

Of course, their most critical problem before, that is, the problem of thermal expansion coefficient, has also been perfectly solved.

According to the measurement, the TA1203 produced by this new process...

No, it should probably be renamed TA1303 now.

In short, its thermal expansion coefficient is also optimized by about 50% compared with before.

Now, even at a working temperature of 1303, it will never interfere with other components due to thermal expansion!

All problems are solved perfectly!

"This is really... a bit incredible!"

Everyone felt incredible.

Only a young man standing at the back was not surprised by this.

The young man was Xiao Yi.

For such a situation, it was completely within his expectations.

Precise magnetic levitation fluid control furnace, where is the precision?

It is to allow the atomic structure to be constructed accurately according to the default, so that the interior of the entire material becomes one.

As for impurities?

Under the control of the magnetic field, these impurities will be easily removed, and almost no impurities beyond consideration can enter the interior.

Unless the program is not well designed.

However, since Xiao Yi personally took charge, this matter naturally does not exist.

He turned to look at Wang Changhong next to him.

"Chief Engineer Wang, you have lived up to your mission."

He said with a bow.

Wang Changhong was also excited at this time.

He had never thought that half a year later, Xiao Yi would solve the problem that had troubled them for several years.

Moreover, the solution was so perfect!

He also bowed back and said very solemnly: "Chief Engineer Xiao, thank you very much."

Then, he turned to look at the people present and shouted: "Okay, don't be excited. Next, prepare to complete the last step - produce blades, modify the engine, and then..."

"H-20 takes off!"

...

Chapter 271 Fighting terrorism or fighting deception?

The entire H-20 project started running again.

The entire project team had basically stopped because of the deadlock on the engine. Many researchers returned to their original positions and started to study some new things.

Now, with the problem of turbine blade materials completely solved, Wang Changhong, the chief designer, immediately reassembled the team and began to prepare for the final step.

Of course, the engine must be installed first.

With the super cup version of the control furnace working at full capacity, all the turbine blades were finally produced.

Of course, these blades need to be surface treated later.

Mainly coatings, etc. These coatings can further improve the overall performance of the blades, such as improving thermal conductivity and other performance. This step also takes a certain amount of time.

In this way, about a month and a half later, the blades were completely processed and reassembled with the engine, and then taken to one of the most advanced wind tunnel devices in the country, the JF-22 base.

"Is this our engine?"

"Yes."

In front of the wind tunnel, Xiao Yi looked at a cylindrical device hoisted in front.

Today is the time for the engine to be officially tested, and he was also invited to come to the scene to witness with his own eyes what kind of performance this domestic engine will be able to show.

And the cylindrical device in front of him is that engine.

"Come to think of it, I still don't know what this engine is called."

Xiao Yi asked again.

Wang Changhong next to him smiled and said, "Whirlwind 20S, it's basically confirmed to be called this."

Xiao Yi nodded.

There are rumors that the turbofan 20 itself is to be installed on strategic bombers. Now that it has been upgraded and turned into 20S, it is normal.

At this time, the intercom in Wang Changhong's hand rang: "Chief Engineer Wang, the wind tunnel has been debugged and the engine has been successfully connected. You and Chief Engineer Xiao can come back."

"Okay, I'll be back soon."

Wang Changhong responded, and then he turned to Xiao Yi and said, "Chief Engineer Xiao, let's go back to the control room."

Xiao Yi nodded.

Back to the control room, there were quite a few people watching.

Soon, the test began.

The first is the pre-experiment to confirm that the engine and wind tunnel can start normally.

This step is naturally not a big problem.

After that, the formal test began.

As the operator started the wind tunnel and the engine, the whistling sound suddenly sounded, and the more than 260-meter-long wind tunnel suddenly emitted an extremely strong wind.

If people stood here, they would probably immediately this piece and that piece.

Of course, the wind tunnel began to roar, and the WS-20S was no different. They started at the same time, and the two always kept the same rhythm.

The tail flame sprayed out, and the powerful driving force allowed it to always resist the strong wind brought by the wind tunnel, so that the connecting chain hanging it always remained vertical, as if there was no force at all.

In the control room, everyone looked at the situation in front of them and held their breath.

They all knew that the next step was the key, and now it was just the beginning.

In this way, as the thrust of the engine became stronger and stronger, and the data from the sensor showed that the temperature before the turbine had reached 1873 degrees!

As for the operating temperature of the turbine blades, it has also reached 1200 degrees.

However, everyone knows that it can be raised!

Wang Changhong gave the order without hesitation: "Continue, 1300 working temperature, see how high the turbine temperature can reach!"

"Yes!"

The staff responded excitedly, and then continued to increase horsepower.

A moment later, when the working temperature of the turbine blades reached 1300 degrees, everyone looked at the turbine temperature displayed on the big screen.

2027!

"Is this true..."

They were stunned.

Surprisingly, it exceeded 2000 degrees Celsius...

The American F135 engine is said to have reached a turbine temperature of 1950 degrees.

However, this is the rumor, and no one knows what it actually is.

But considering that Americans often brag about this kind of data, the possibility that this data is false is higher.

Especially according to some performances in actual combat, the turbine temperature of the F135 does not seem to be able to reach 1950 degrees.

But no matter what, China still maintains a skeptical attitude towards this data for the time being, trying to catch up.

Anyway, the Chinese have done this before...

But now...

They have not only caught up with the data, but also exceeded it by so much, and even exceeded it by 2000 degrees!

2000 degrees.

This is definitely a milestone record in aviation history.

Of course.

It is not important to be just 2000 degrees.

Everyone's mood gradually calmed down and began to pay attention to other data.

For example, the thrust reached 26 tons directly!

And the overall thrust-to-weight ratio reached an unprecedented 16:1.

In the past, no engine has ever been able to achieve such a thrust-to-weight ratio.

And now, they have achieved it.
