He Yongqing thought that the population of Central Plains Province now has more than 60 million, but it is more than the population of the whole of South Korea of more than 40 million, and the land area is more than twice that of South Korea.

Now the Central Plains Province has taken the opportunity of the national development of large passenger aircraft projects to pull the aviation industry over, and it also attaches great importance to this, and He Yongqing and other senior executives of COMAC Group are also full of confidence in this.

As long as the upper level attaches importance to it and the local government supports, the possibility of this thing being done is very high, and it is rare for the order to change overnight.

More than an hour later, two King Long business buses approached the place where Yonghan Aviation Power Technology Company was located.

Seeing the factory building covering an area of thousands of acres, He Yongqing's eyes also widened, he looked at Yang Jie and said, "Yang Shao, you haven't invested in the factory here, right?"

"Hehe, these hardware facilities are not cheap, if you add the high-altitude test bench, I have invested more than 2 billion US dollars in this in recent years. ”

“......”

He Yongqing, He Zhipeng and others all opened their mouths wide and were speechless for a long time.

"Yang Shao, you are really willing to invest in this aero engine factory!"

He Zhipeng said in shock that it was the first time he had seen someone in China dare to spend so much money on a high-risk aero engine project.

"I don't have many hobbies, I like to engage in technology research and development, and I am personally very interested in the aviation field, so let's toss around on aero engines. ”

Yang Jie said with a smile: "These are my personal investments, and they will not affect the capital chain of Huaxing Group Company, and they can be tossed to whatever extent they can be tossed." ”

He Yongqing and He Zhipeng exchanged glances, and a thought came to their hearts at the same time: being rich is capricious!

Like those rich people abroad who are rich and make all kinds of investments like casting a net, this Yang Shao is good, and he plunged into this high-investment and high-risk aero engine business!

The research and development of an aero engine is at least one billion US dollars, and the maximum investment of more than three billion US dollars is also available, and the cycle is very long, at least six or seven years, and the probability of some developed engines not making money is also relatively large, if the engine can not sell hundreds of units, then these investments will be smashed in the hands.

And even if you have money, you can't necessarily play it, and if the company doesn't have thousands of experienced engineers in the aerospace field and a large number of senior technicians, the money may not be able to develop a successful engine.

Such a money-burning thing can only be played by some countries with a large size and strong overall technological strength, and some small countries simply do not have the capital to touch this matter.

But now this Yang Shao has actually played this matter, and he has played very well, the first engine has been designed and finalized, and he is really a very bold and capable character.

After entering the factory, Yang Jie also accompanied Ma Qiulin and others into the office building and into a reception room that had been prepared long ago.

Ma Qiulin said to Yang Jie with a smile: "I heard that your company is developing a new engine, how far has it progressed now?"

Yang Jie glanced at Wang Yonglin, who immediately said: "Governor Ma, we are still doing the preliminary design of the new engine, and now we have completed the communication on the needs of some domestic customers, determined the design plan, and are now doing technical demonstration." ”

Because Yonghan Airlines has developed a very rigorous and meticulous R&D process, the company must design and determine the performance parameters, size, maintenance engineering, and final assembly design requirements of the engine according to the needs of the military before designing, and make a preliminary design plan, and then it will be specifically refined to the design of the engine itself.

Prior to this, Yonghang Airlines also sent a group of technical and engineering personnel to the military to communicate and understand the specific needs of these military customers.

"Your speed is really fast!" Ma Qiulin said with emotion.

"Our customers are in a hurry, and they have to speed up. Wang Yonglin said.

"Mr. Wang, it is rare for Mr. He and Mr. He to come over and show them the samples of the third-generation monocrystalline turbine blades we developed. Yang Jie said with a smile.

"Okay, Yang Shao. Wang Yonglin nodded, and then made a phone call.

"What, Yonghan Aviation Power Technology Company has mastered the third generation of single crystal material technology?" He Zhipeng asked in shock.

According to what he knows, China has just made some progress in the second-generation single crystal material technology, and has not fully mastered the preparation and processing technology of materials.

"Haha, our company's Dr. Liu is a genius in this area, and he has only recently overcome the preparation process of the third-generation single crystal material, the company is trial-producing turbine blades, and the process is still being explored, but now a batch of turbine blades has been trial-produced, and the process is now being improved. ”

Yang Jie said with a smile.

After more than a year of hard work, the technical team led by Dr. Liu Fuping has carried out research work on ceramic core technology, corundum shell process, single crystal crystal selection and directional solidification process, single crystal blade recrystallization control, and ceramic core positioning technology.

After a large number of tests, the technical team has accumulated a lot of data and experience in ceramic materials and formulas, roasting temperature control, casting process parameters, crystal pulling rate, process route adjustment, and mold improvement, and the metallurgical quality, microstructure, chemical composition and mechanical properties of the prepared hollow single crystal blades have met the design performance requirements, and the pass rate of the blank can reach 60%.

In this process, the molecular orbital method was introduced into the alloy design for the first time, and the combination of MO equivalent method, electronic theory method and computer simulation can quickly design the required superalloy formulation.

Liu Fuping has worked in the alloy materials department of Honeywell for more than 20 years, and has a large amount of experimental data in his head, and after returning to China, he also used the experimental data he has mastered to build a set of alloy design data models.

Through experiments, it has been proved that his alloy design model algorithm is very advanced, which greatly reduces the time for developing alloy materials, and the designed alloy materials meet the design requirements.

In addition, Dr. Liu has mastered the technology of thermal preparation and processing of powder alloys, and has also solved the problems of preparation and processing of these designed alloy materials.

The company also gave Dr. Liu Fuping and the team rich material rewards.

In order to solve the problem of alloy processing, the Machine Tool Research Institute has also developed a special alloy tool, which solves the problem that the tool is easy to produce edge edge and tool tip in the processing process of nickel-based superalloy, which is easy to produce edge edge and tool tip, as well as serious boundary wear and high cutting temperature, and also develops special welding materials.

After a while, the staff brought over a sample of a turbine blade.

He Yongqing looked at this third-generation single crystal turbine blade with great interest, the blade looks very beautiful, the inside is hollow, and the curved surface of the blade is very beautiful, and the row of small cooling pores on the blade body is also very beautiful.

"Ah, you use air film cooling technology, right?" He Yongqing asked in surprise.

"Yes, we use air film cooling technology, the blade surface is also sprayed with thermal barrier coating, we use electron beam physical vapor deposition method, according to our experimental tests, thermal barrier coating plus air film cooling technology can make the superalloy material withstand high temperature of 2000 degrees. ”

Wang Yonglin said proudly.

"Now the most advanced engine temperature in the United States is only 1,700 degrees Celsius, right?"

He Yongqing looked at He Zhipeng.

According to the information, this is indeed the case. He Zhipeng nodded.

Because of the coating, the blade is gray-black, with a special beauty, He Yongqing looked at this turbine blade with great surprise, as if he was looking at a treasure.

"So, your company can now design the fourth-generation turbofan engine?"

He Yongqing looked at Yang Jie and asked Wang Yonglin.

"We have only mastered the third-generation core machine technology, and now we have only just mastered the third-generation single crystal material technology and thermal barrier coating technology, and it will take several years to design the fourth-generation core machine. ”

Yang Jie said.
