The Immortal Warrior: From Reverse Engineering to Forging Swords for the Country

Chapter 85 Turbine blade cooling technology [seeking data for reading]

The content of this banner was requested by Zhang Zhipeng.

There are only eight words: stay anonymous and forge swords for the country!

Mr. Qian finished it with a wave of his hand. Looking at the eight big characters dripping with ink, he nodded thoughtfully and said happily: "Comrade Xiao Zhang, these eight characters are great!"

"Scientists who truly serve the country and the people do not pursue fame and fortune!"

"Our only purpose in life is to serve the country and the people!"

"Are these 8 words your motto?"

Zhang Zhipeng nodded and said, "Yes, I hope to make a small contribution to the development of the country!"

Mr. Qian nodded very moved and said, "Okay! This is the backbone of our nation!"

"This is the true scientific spirit!"

"These eight words are also my pursuit in this life!"

Zhang Zhipeng smiled and said: "Mr. Qian, this is also a reflection of your life! Ah"

"The contribution you have made to the country is more than a hundred Nobel Prizes can equal!"

Qian Lao smiled and shook his head and said: "I may have made a little contribution to our country, but your evaluation is too high, haha! But to be honest, I have never yearned for that award!"

"Winning awards is never a way to prove greatness!"

"There is only one way to prove greatness, and that is to make great contributions to the people of the country and the people of the world!"

Mr. Qian left and Zhang Zhipeng and others sent him off respectfully.

Zhang Zhipeng thought to himself, only someone like Mr. Qian can truly deserve the evaluation of "a person with capital letters", right?

After Mr. Qian left, Zhang Zhipeng, Song Likun and others combined.

Later, he went to the 105th Institute to inspect the condition of their newly developed engine.

I have to say that in fact, there are no problems with the various technologies of Rabbit's new aero-engine.

What is lacking is the obstacle of single crystal turbine blades.

Zhang Zhipeng stayed in No. 105 for more than ten days.

In the process, he thoroughly studied the domestic engine being developed.

With the help of the system, his capabilities in aircraft engine process design and other aspects have been greatly improved.

Zhang Zhipeng helped Li Ruihai's team make some improvements and improvements to the engine.

It turns out that the turbine blade cooling method designed by Li Ruihai's team is convection cooling.

That is to say, the blades are made hollow, with multiple air channels formed inside. High-speed airflow is driven from the blade root and ejected from the blade tip to take away heat. The cooling efficiency depends on the cold air flow rate.

This design can cool the turbine blades by 200 to 250 degrees.

Zhang Zhipeng proposed the design of composite cooling technology.

Convection cooling can also be done, and at the same time, film cooling technology is added.

The so-called film cooling method is actually to design many pores on the turbine blade surface. The cold air blown out from these pores forms a cold air barrier on the turbine blade surface, thereby maintaining a relatively low cooling rate on the turbine blade surface to a considerable extent. temperature. The air film design can cool the turbine blades by 300-400 degrees.

It can be said that the heat resistance limit of turbine blades is the design indicator of the combustion chamber outlet temperature.

Therefore, as long as the cooling technology is done well, there is still a lot of room for improvement in the temperature of the combustion chamber.

The higher the temperature of the turbine combustion chamber increases, the more powerful the aircraft engine will be.

If the turbine blades are made of directionally solidified alloy, because its melting point is too low, the temperature in the combustion chamber cannot increase too fast or too high, otherwise the turbine blades will easily melt off.

But now, Zhang Zhipeng has led the team to develop rhenium single crystal blades.

The melting point of this rhenium single crystal blade has been significantly increased by more than 300 degrees.

This leaves room for significant improvement in engine performance.

Li Ruihai, director of Institute 105, was very shocked.

He never expected that Zhang Zhipeng would be so professional in aircraft engines!

These innovative technologies proposed by Zhang Zhipeng are really important to them.

"Comrade Zhipeng, you have helped us a lot!"

"Now, the performance of our new aircraft engine will be greatly improved by at least 50% due to your technical transformation!"

"This is really important for our third-generation aircraft to improve the performance and catch up with the world's advanced level." Zhang Zhipeng smiled and said: "Teacher Li, you are still doing the main work!"

"I'm just helping you guys out!"

"I should learn from you!"

"Now, the innovations we can improve have basically been improved."

"Next, I hope to take out WS-10 as soon as possible!"

"Let's split up!"

"After I go back, I will start the production of rhenium single crystal blades."

Li Ruihai nodded and said, "Okay! Let's split up!"

"As long as rhenium single crystal blades are produced, our new aircraft engine is expected to be available and start testing before the end of this year!"

"I hope that in early 1992, our new generation J- fighter will begin test flights!"

Zhang Zhipeng flew back to Chang'an from Sichuan Province.

At this time, it was already early September of 1991.

While Zhang Zhipeng was at Institute 105, Zheng Jingzhi and others were also busy.

Zheng Jingzhi has already begun preparations for the mass production of rhenium single crystal blades.

The production workshop is located in an experimental factory of NPU.

Customized manufacturing of various equipment has also begun.

Mainly heat treatment furnaces and single crystal furnaces, and of course other auxiliary equipment.

Laboratory production and factory mass production equipment are definitely different.

It needs to be modified and adapted to the needs of mass production.

For these large-scale mass-produced equipment, Zhang Zhipeng and Zheng Jingzhi and others have already completed the process manufacturing design.

Therefore, equipment production is quite smooth.

Of course, the manufacturing of this kind of equipment also requires Zheng Jingzhi and others to keep an eye on the scene.

When Zhang Zhipeng returned to Chang'an, the production of the equipment was almost completed.

In the next few days, the production line for rhenium single crystal blades will be set up.

After all, this requires dozens of processes!

Every craft is important.

A little carelessness may result in defective products.

The production line was laid out, and Zhang Zhipeng personally led the team to conduct production debugging.

By mid-to-late September, everything was ready.

Mass production of rhenium metal single crystal blades has officially begun.

Before the mass production of this most important aircraft engine accessory, Zhao Bingkun rushed to the scene in person.

After he saw Zhang Zhipeng, he smiled and said: "The series of papers on rhenium single crystal blades written by you and Teacher Zheng's team have been published. They are all top domestic publications!"

"Moreover, we have also applied for major national scientific research achievement awards specifically for you!"

"Your team received a total bonus of 20!"

Zhang Zhipeng said with a smile: "Thank you, Director Zhao, the bonus is quite large. Is our achievement expected to win the country's highest technology award?"

Zhao Bingkun nodded and said, "That's necessary!"

"In fact, your breakthrough in domestic CPU is also expected to win the highest national science and technology award!"

"It's just that we need to hide you now to ensure your safety, so we didn't award you the award!"

"Comrade Zhipeng, don't worry! The country and people will never forget your great achievements!"
