The news media have followed up to report the news of the successful first test run of the turbofan engine of Yonghan Aviation Power Technology Company, which is like a bombshell that completely detonates the major forums and chat communities on the Internet.

In particular, those military enthusiasts, military enthusiasts, and even many people in the industry have expressed their opinions.

Many people expressed their excitement, and of course, many people expressed their suspicion that it was an unknown private company that developed a high-fidelity turbofan engine!

What is the origin of this Yonghan Aviation Power Technology Company has become a suspicion for many people.

As some netizens turned out the name of Yang Jie, the registered legal person of Yonghan Aviation Power Technology Company, many people made it clear: Originally, this company was the personal company of the owner of Huaxing Group Company, no wonder it was so bullish!

Looking at the fact that the company was registered two years ago, this very mysterious tycoon has already begun to find new toys!

Some netizens even jokingly said: Although this rich man snatched the goddess of my dreams, I still supported him to engage in aero engines, this guy is really powerful, he dares to play aero engines!

……

The day after the grand celebration banquet held by Yonghan Aviation Power Technology Co., Ltd., the engine was transported from the test workshop back to the final assembly workshop, and then it was disassembled and disassembled into a parts state.

After the engine is disassembled, the technical staff will conduct a strict inspection of each part to see if there are any changes and problems in each part after passing the test.

If you create a problem, you need to analyze it and find out the cause.

After the first verification test of the first verification machine, there are always some parts that will have problems, what type of problems are critical, whether they are serious, and whether the design or process needs to be improved.

The verification machine is used to verify the design, production and assembly process, materials and other aspects, and even, sometimes, to carry out a design improvement, or the application of a new material, the new process can also be verified by the verification machine test.

The disassembly of the aero engine is much faster than that of the assembly, which took more than a week to assemble, but the disassembly took less than a day.

Now, the engine is in the state of parts, which have been carefully cleaned and arranged in different areas by component.

The technical staff and inspection staff of the final assembly workshop all start to work, perform visual inspection of parts, perform dimensional measurements, and even metallographic analysis if necessary.

Tang Zhengwang and other expert groups also rushed over, and Liu Jianqing also stayed in Tanzhou City for a few more days this time, also to understand the situation of Yonghan Aviation Power Technology Company.

In the office, Liu Jianqing and others were also talking to Yang Jie.

"Your company can now succeed at one time, confirming that the core engine technology of this engine is mature, and I am surprised that your company is too rigorous in the management of the production process, and these domestic aero engine OEMs should learn from you." ”

Liu Jianqing said with a sigh.

"Old Liu, if you say that, it will make those people in the main engine factory hate us. Yang Jie said with a smile.

"We also need Yonghan to give them a whip, compared with your Yonghan company, these OEMs are very rough in production and assembly, which is also one of the important reasons why turbofan 10 always has major problems. ”

Zhang Kelong also sighed: "In the past, we always thought that we couldn't build engines because we couldn't do it in terms of materials and processing, and now we are better than Russia in some aspects, but we just can't build good aero engines." Russia is able to use these materials to create an advanced engine comparable to Europe and the United States, the design degree and assembly process is much higher than our domestic OEMs, and now you Yonghan can find these experienced talents to establish a complete set of detailed and complete production standards, it is really rare. ”

"I have reported this matter to Chairman Yang, and the center has decided to establish this engine of your Yonghan Company and this turbofan 10 of Liming Engine Company as a key project at the same time. ”

Liu Jianqing said: "Before we took the turbofan 10 as the only key project, the country's two major models of fighters are going to apply this engine, and the two feet of the military are standing on the same boat, which is a big thing related to the life and death of our two key fighter jets, and now you can make another independent core aircraft, this is a great thing!"

He looked at Yang Jie and said: "Now your fuel cell and motor skills can fully replace high-power diesel engines, and the progress in replacing turboshaft engines is also very smooth, I also look forward to seeing your company can cooperate with the four major domestic OEMs to solve the problem of turbofan and turbojet engines as soon as possible, complete the design of the engine within three years, and start to supply stable and reliable engines for military fighters." ”

"Since the military and high-level trust us so much, we will definitely live up to the expectations of the leaders, and make this core machine mature and reliable within three years, and derive more models of engines on this basis!"

Yang Jie said with a firm face.

"Well, the technology of this engine core machine of your company belongs to the skills of the fourth-generation core machine, if it weren't for seeing the real thing, I can hardly believe that you have made such great progress in monocrystalline materials. Liu Jianqing said.

"The real machine tool research institute in the single crystal high temperature materials began to study relatively early, and later with the participation of Dr. Liu Fuping, to solve the processing technology problems of these single crystal materials, Konstantin they have rich design experience and production experience, this matter has become relatively easy. ”

Yang Jie said with a smile.

Huaxing Group Company has many top thermophysical scientists and chemical scientists, and the preparation skills of semiconductor materials have been very mature, and a single crystal alloy material weighing more than ten kilograms has been prepared by a relatively mature liquid phase method.

These materials are also used in the parts of Hengshan turbofan engines, including turbine blades, guide vanes, blade inner and outer rings, nozzle fan sections, sealing blocks, fuel nozzles, etc.

Liu Fuping controls the design and manufacturing skills of monocrystalline turbine blades, and has many patents on high-temperature coatings, which is one of the important reasons why the Hengshan engine test designed and developed by Yonghan Aviation Power Technology Co., Ltd. can be successful at one time.

Monocrystalline turbine blades are currently the engine parts with the most manufacturing processes, the longest cycle, the lowest pass rate, and the most strict foreign closure and monopoly among all aero engine parts.

Yang Jie used a lot of connections to get Liu Fuping back to China, and Liu Fuping was also extremely grateful, so he naturally tried his best to apply the patented skills he controlled to this Hengshan engine.

Think about the current domestic West Airlines engine company has not yet controlled the second-generation Spey engine technology to know the gap between the domestic aviation technology and foreign countries, and now the domestic J-8 is still equipped with 50 Spey engines purchased from Rolls-Royce in the eighties of the last century, and now it is also purchasing spare parts from Rolls-Royce Company in the inventory of Spey engines——

Rolls-Royce has long stopped producing this engine, and the rest are some parts in stock, and the West Airlines has not yet mastered the skills of this engine.

In recent years, we had to purchase a batch of RD---33 engines from Russia, and at the same time, there is also a foreign trade version of the single-engine fighter that also needs an engine.

Now the three armed forces want better weapons and equipment, and the four major domestic aero engine OEMs are not strong, so it is no wonder that the senior military staff and the center are so serious about the core aircraft of Yonghan Aviation Power Technology Company.

Liu Jianqing looked at Yang Jie at this time and said: "You also know the situation of several domestic aero engine OEMs, and the military is also looking forward to seeing that your company can supply monocrystalline high-temperature materials and processing technology to these four companies......"

After saying this, the heads of several aviation engine factories who came over this time were a little embarrassed.
