Yang Jie said with a smile: "We are also very willing to cooperate with domestic aviation companies, and our company can supply monocrystalline high-temperature materials and process licensing." ”

In fact, the origin of the four domestic OEMs' aero engine skills is very complicated, and they are also fighting for the cold war with each other, and the resource integration work is not in place, but each company is very skilled, and the foundation is from the sixties and seventies of the last century to enter the field of aviation development, and it has indeed created a lot of technical experts, which Yang Jie also attaches great importance to.

For example, Wang Yonglin and Konstantin have participated in the complete experience of several engines from design to production and assembly, which is also the advantage of Yonghan Aviation Power Technology Company.

Yang Jie is also looking forward to seeing that the company can supply processing materials and process authorization to these domestic OEMs to form a very good supply chain, and the company's important energy is focused on the design and development of aero engines, which can also greatly save time and cost.

Hearing Yang Jie's promise, many expert groups and the heads of the main engine factory who rushed over this time were overjoyed.

In particular, Yang Xianfeng of Liyang Engine Company is even more excited, turbofan 10 has now been produced to more than ten prototypes, technical performance is not able to catch up with the Hengshan engine, and some systemic problems of the engine have not been completely solved, the first overhaul life is only a pitiful 300 hours, which is too big with the 2000 hours of overhaul life of foreign engines, and his pressure is very great.

He heard that the monocrystalline turbine blades made by Yonghan Aviation Power Technology Company have a life of more than 2,000 hours in the laboratory under high temperature and high pressure environment, although this achievement was completed in the laboratory, and there is a certain difference in the actual assembly of the engine, but it will not be much worse.

If all the turbine blades of the turbofan 10 can be replaced with Yonghan's materials, the life of the engine will be greatly extended - the life of the whole engine is only 900 hours on the basis of the current domestic engine.

"Yang Shao, can your company help our company produce a batch of turbine blades?" Yang Xianfeng said to Yang Jie at this time.

"Of course, we can ensure that the application life of the blades is more than 1,000 hours. ”

Yang Jie is naturally confident in saying this, the material engineering center of Yonghan Aviation Power Technology Co., Ltd. has been established, with advanced metallurgical equipment and advanced material analysis and experimental equipment, and there are also material skills like Liu Fuping.

"Yang Shao, can the application life really reach more than 1,000 hours? ”

"Liu Lao is here now, where do I dare to tell lies. Yang Jie said with a smile.

Yonghan Aviation Power Technology Co., Ltd.'s blade production workshop has been very sound, the equipment has been in place, more than 100 employees, now the company's engine has not entered mass production, the blade production workshop production tasks are few, and other production workshops are the same, he naturally wants to try his best to pull the business.

"That's great, I'll call the company later, and transfer all the orders for turbine blades to your company." ”

Yang Xianfeng said excitedly.

In Vietnam, Yang Jie also learned that the assembly workshop had created several problems when inspecting the disassembled parts of the engine, and he also rushed to the past for a relatively big problem.

"Yang Shao, the color of the inner wall of the flame cylinder is abnormal, this part is determined to be poor cooling, and the local temperature is a little high. ”

Wang Yonglin said to Yang Jie.

Yang Jie put on white gloves at this time and shone the inner wall of the flame tube with a flashlight, and sure enough, there was a part where the color was a little wrong, obviously darker.

When the flame barrel is working, it is a mixture of mist fuel and air to burn, and the combustion speed is very fast and the temperature is very high. At high temperatures, the flame barrel will work for a long time and the surface color will change, of course, this color change is normal.

However, if there is an abnormal color change, it is a big problem, which may cause a change in the metallographic structure of the flame cylinder, thereby changing the performance of the flame cylinder, affecting the application life, and seriously ablating the flame cylinder.

The flame cylinder of the aero engine is not allowed to be in direct contact with the flame burning in the flame cylinder, and it is necessary to isolate it, the flame cylinder of the Hengshan turbofan engine is important in terms of flame isolation, and the thermal barrier coating and the film are cooling, but the theory and practice are often very different, and the design theory is very perfect, but some problems arise in the actual process, which is not impossible.

The flame cylinder designed by Yonghan Aviation Power Technology Co., Ltd. is very advanced, very fair and perfect, it is Wang Yonglin and Konstantin personally checked, it stands to reason that there will be no problems, but the actual and design theory are sometimes not completely consistent, and now there is such a problem.

The look on Konstantin's face was a little unnatural.

Yang Jie didn't get angry, he opened his mouth and asked, "How do you solve this problem?"

Konstantin began: "We need to make certain design improvements to the flame barrel to further improve its cooling performance. ”

With his translator translated to Yang Jie.

"Well, then come up with a revised design plan as soon as possible, and I'm waiting to hear the good news about your second test test. ”

Yang Jie nodded and said.

This inspection also created some problems, Wang Yonglin and they also came up with specific solutions, and Yang Jie was also relieved after understanding this situation.

A few days later, Yang Jie and Song Manli appeared outside a small welfare home in Yangcheng.

At this time, Song Manli was standing outside the wall, looking in, looking very anxious.

In the courtyard of the welfare home, there are twenty or thirty children of different ages, playing under the leadership of their aunts, doing various games.

The children were very happy and laughing.

Although the scale of this welfare home is not large, the facilities are very good, and there are all kinds of children's play facilities in the yard. It is surrounded by flowers and plants, and the environment is beautiful.

"Sister Manli, don't worry, our son has someone to take him, the child is still young, and these outdoor group sports are also suitable for him. ”

"Let's move on...... I can't wait. ”

Song Manli said anxiously, but Song Manli, who had always been dignified and elegant, showed an impatient expression at this time.

"Okay, but be careful, don't get seen by our son on the road, that's a bit of a problem. ”

Yang Jie: They didn't go through the gate, but walked through an inconspicuous small door next to them.

"Why?"

Song Manli followed him firmly and asked.

"You haven't been away with our son for long, haven't you? Wait until he sees you, and when he calls Mom, won't he be all exposed?"

Yang Jie said with a smile.

"What are you seeing? I'm his mother'......."

Song Manli muttered dissatisfiedly.

Yang Jie smiled and did not speak.

The two entered the welfare home through the side door, and at this time, a woman in her thirties greeted her with a smile and said in a low voice: "Mr. Yang, Miss Song, you are here!"

"Xiaojie, is this what she is specifically responsible for taking care of Hejie?"

Song Manli asked.

Yang Jie nodded.

The secretariat also arranged for two nursery teachers to take care of Yang Jie and Song Manli's son here.

"Come with me, both of you. ”

After a while, Yang Jie and Song Manli followed the nursery teacher to the office of the welfare home.

Song Manli couldn't wait to ask, "Ms. Liu, where is Xiaojie?"

The nursery teacher, surnamed Liu, poured water for them and said with a smile: "I was originally playing here, but I was arguing to go out to play just now, so Xiao Cai took him out." Don't worry, I'll be back soon. ”

Song Manli couldn't sit still at all, and looked up at the door from time to time.

Yang Jie asked, "Aunt Liu, have you grown taller with Jie?"

"Mr. Yang, you just came to see it last week, although children grow up fast, it won't be so obvious, right?" said Aunt Liu with a smile.

Yang Jie also smiled dumbly.

"Xiaojie...... He's not sick, is he?

Song Manli asked with concern.

"No, he's very healthy, what kind of illness can he have? Xiao Cai and I sleep with our children at night, and there will be no problem. ”

Song Manli put her mind at ease, she also knew that Yang Jie would definitely arrange things properly and be foolproof, but she cared about it, she hadn't seen her son for a while, and she couldn't wait to make everything about her son clear.

After a while, she still didn't see her son come back, Song Manli became anxious again, and said, "Aunt Liu, can you go out and look for it?"

Aunt Liu agreed with a smile, got up and went out.
