At this time, Miao Yi put the blades into the turbine tenon one by one according to the weight number, and the blades were loaded into the tenon groove naturally There are locks, which are used to lock the blades.

He held a small hammer in one hand and a small copper rod in the other, and gently struck to bend the lock blades one by one.

Yang Jie couldn't help but nod secretly when he saw such skilled skills.

At this time, Miao Yi began to use a special measuring tool to measure the swing of the blades one by one, while his two apprentices recorded on the side and recorded the measured swing of the blades on the table one by one.

To the surprise of these expert groups, all the swing of these blades were qualified, which was very difficult.

"Master Miao, your level is too high, you can pass all of them at one time. Tang Zhengwang couldn't help but admire.

Generally speaking, before assembly, the appropriate turbine blade should be selected, and the experienced assembly master can determine by his own feel whether the swing amount of this blade will be qualified after locking the lock plate, and it is very rare for Miao Yi to be qualified at one time.

Miao Yi grinned.

Since the establishment of Yonghan Aviation Technology Co., Ltd., Yang Jie is also a bad supplement in this area of technical materials, he knows that the assembly of aero engines and parts machining is very different, parts machining, can be clear in the process of specific process steps, fair process parameters, workers in accordance with the machining process procedures to operate, as long as the degree of workers is not too bad, generally can process qualified parts, if the workers are serious, a little higher, the processing of high-quality parts can also be.

The aero engine assembly is a little different, the process specification is clear and specific process steps, the fair process parameters are only one of them, and the quality of the assembly is largely related to the skill of the assembly workers.

Like the turbine blade assembly just now, to a large extent, it depends on the skilled assembly skills of the workers, if the skill level is not good, it may take half a day to assemble, and there may be repeated disassembly, and repeated assembly can meet the skill requirements.

For the general assembly workshop, each high-level skilled worker is a great wealth, the more such wealth, the more abundant, the higher the quality of the assembled aero engine, and the smoother the whole assembly process.

Yang Jie also used a lot of connections to dig up such a group of senior assembly technicians with more than ten or twenty years of experience from these domestic aviation companies.

Then everyone went to the assembly area of the combustion chamber.

The assembly of the combustion chamber is also very skillful, the assembly request is very high, in the assembly process, the workers have to constantly check the runout of the assembly parts, coaxiality and other skill requirements, once the grid is different, but also disassemble and reload.

Because the flame cylinder adopts the floating wall type wall structure, the welding and deformation control of the head of the flame cylinder are extremely difficult, and the inner ring adapter section, the outer ring of the flame cylinder, the vortex device mount and the splash plate are directly welded with the head, between the first two and the head adapter section is a large butt annular electron beam weld, and between the latter two and the head adapter section is a vacuum brazing seam, especially in these welds, the largest deformation of the opening end adapter section is 2 electron beam welds.

In order to understand how to solve these difficulties, Wang Yonglin, Konstantin and others also went into battle in person and used some special techniques to solve these difficulties.

At present, the combustion chamber assembly is only the assembly and welding of the main combustion hole short tube mixing hole short pipe on the outer ring of the flame cylinder, and there is no outer ring and inner ring of the flame cylinder welded on the head turning stage at the same time to form a skeleton, and then the brazing eddy vortex mount and splash plate are assembled to the head transfer section to form the stage of the head of the flame cylinder, but there is no need to keep it secret from these expert groups.

After the assembly of the head of the flame cylinder is completed, the welding ignition nozzle and the jet nozzle are assembled, the inner ring adapter section and the outer ring are assembled and the electron beam welding overall cap is assembled, the assembly and welding of the outer ring cylinder of the flame cylinder are completed, and the vacuum heat treatment, calibration, head and suspension are processed, cleaned, marked and final inspection are completed, which is the real completion of the assembly of the combustion chamber.

This assembly process will take at least a few days.

The assembly of an aero engine, all kinds of records, all kinds of materials, all kinds of forms, very much, after the assembly of the aero engine, these things should be packed and bound into a book, generally every aero engine has a thick book.

These materials, together with the relevant materials for the commissioning, add up to become the resume of the aero engine, a thick one.

Each aero engine has its own thick resume, which should be specially preserved, and it should be kept for more than 20 years.

Only by going through these processes very carefully and conscientiously, and then there will be quality problems with the aero engine, and the cause of the aero engine problem can be quickly determined according to these resumes.

Liu Jianqing watched the assembly workshop for a long time, and he asked Yang Jie and Wang Yonglin: "How long will it take for this engine to be finished and enter the test stage?"

"Liu Lao, it will take two weeks to complete the final assembly of the first turbofan engine. Wang Yonglin said.

"Well, I'll come back in two weeks, and I hope to hear good news from you when the time comes. Liu Jianqing nodded.

"Mr. Liu, I will be the first to inform you when the engine assembly is completed and the test run is lagging behind. Yang Jie nodded.

After sending Liu Jianqing and others away, Yang Jie also held a meeting with Wang Yonglin, Konstantin, Liu Fu and others in the office building of Yonghan Aviation Power Technology Company.

Liu Fuping, Qiu Wenkai and Zeng Qingyuan, three technical experts, are in charge of the process, while Wang Yonglin is the president and also serves as the process director, and Konstantin is the design director, and they have been firmly focused on the assembly of the engine during this time.

At this time, they were also reporting to Yang Jie.

"Yang Shao, so far, the assembly of the first verification machine has exposed a series of problems, but fortunately there are no major problems. We have written down these small problems and shortcomings one by one, and some of the problems may need to be corrected in small ways. ”

Wang Yonglin said.

"It's okay to have no major shortcomings that arise. Yang Jie opened his mouth and said that he would not interfere in the specific assembly process.

The time came to the end of May, and the first demonstration aircraft of Yonghan Aviation Power Technology Company finally entered the final assembly stage.

Yang Jie, who learned the news, also rushed over immediately.

"Yang Shaohao is good!"

Everyone saw Yang Jie coming over and said hello one after another.

"What's the situation?" Yang Jie also asked eagerly.

Wang Yonglin said: "The preparations have been stopped, and the final assembly of the first verification machine can be started immediately. ”

He couldn't hide his joy and excitement in his tone, and the people around him looked excited.

Yang Jie waved his hand: "Start assembling !! immediately"

Several workers in charge of the general assembly are skilled assembly workers, with rich experience in aircraft assembly, they have carefully digested the general assembly process regulations of this Hengshan turbofan engine, and with Yang Jie's order, they will start work immediately.

Several major components of Hengshan turbofan engine have been assembled in the early stage, and the final assembly is to assemble these major components together, and then assemble the accessories behind the row, including the control part, oil circuit, circuit and so on.

The assembly workers have a very good degree of skill, install the combustion chamber parts on the final assembly bench, carefully align the two benchmarks, and install the intermediate casing, centrifugal impeller, shroud and other components after the benchmark is aligned.

Seeing the tacit understanding of several assembly workers, Yang Jie also nodded.

Although these assembly workers are assembling this engine for the first time, they have been trained and imitated for a long time before this, and the assembly is quite smooth.

After assembling a part, when it is time to measure the size and coherent skill request, everyone will stop and measure the coherent assembly size and skill request and record them one by one.

After the intermediate casing is installed on the combustion chamber casing, the runout of the end face and inner bore of the intermediary casing is measured, and after the measurement value is measured, if the assembly request is not met, they exchange and fine-tune it.

"Old Chen, knock a little more in the direction of my left hand......"

"Lighten up...... Lighten ...... Okay, stop!"

The skill clerk then measured it, and his face showed joy: "OK, meet the request!"
