Yu Guoliang is a person who writes everything on his face, seeing such a "messy" white paper process regulations that have been altered, he was extremely shocked at the same time, his face and body reaction were relatively large, and Li Tianfeng, who was introducing the turbine disk, immediately stopped the introduction and looked at it suspiciously.

Everyone was almost listening to Li Tianfeng's introduction, and as soon as Li Tianfeng stopped introducing, looking at it like this, everyone's eyes also followed, almost all of them focused on Yu Guoliang's body.

Yu Guoliang's face was shocked, angry, and complicated, reflecting the great fluctuations in his heart, and everyone guessed that something should have happened.

Yu Guoliang's chest rose and fell, he was almost speechless, and thought in his heart, how can this be reasonable, there is still such a process specification, not only is it blank paper, but also many places have been modified, and each page is densely written with a pen or ballpoint pen A lot of words and a lot of parameters, and such a process specification is actually placed at the processing site to guide the processing, which is simply lawless.

Li Tianfeng saw that Yu Guoliang's feelings were almost out of control, and he couldn't help but say with concern: "Expert Yu, what's wrong?" ”

Zhang Hongzu next to him also asked suspiciously: "Old Yu, what's wrong?" Something? ”

Trying to take a deep breath, Yu Guoliang raised the white paper craft manual in his hand, and said angrily: "Mr. Li, what's going on, I want an explanation?" ”

Li Tianfeng was stunned for a moment, and thought in his heart that there are many such white paper process procedures in our processing site, and all the parts processing of the "TFWZ001" turboshaft engine use such white paper process procedures, what is unusual.

Immediately, Li Tianfeng quickly understood, and guessed that Yu Guoliang must have seen traces of modification in the process regulations on the white paper, so he was like this.

Zhang Hongzu took this white paper process specification from Yu Guoliang's hand. After a little look, I said in my heart, good guy, I changed a lot of places on each page and wrote a lot of things in a handwritten way. And there's a signature, and there's a date.

It seems to be very non-standardized, almost a mess, but if you take a closer look, it seems very standardized, who changed it, when it was changed, and what things were changed, at a glance. Even some process parameters, methods, and even some deficiencies are noted one by one and signed.

Zhang Hongzu's expression was more cautious, this is not a good one, it is a heavy dà unqualified item, but it seems to be not like it at all, because a qiē modification seems too standardized.

Other than that. This is a blank paper process specification, not a blueprint process specification. Therefore, Zhang Hongzu is more cautious.

Generally speaking, the process regulations issued by aviation manufacturing enterprises to the processing site are all blueprints, and they are not the process regulations bound together in the whole book, but one by one, also known as process cards. One or several of these process cards for a process.

Such a craft card, printed in the way of sun-blue printing, is light blue, and the process drawing, text, etc. are all blue. Such a process card is issued to the processing site, absolutely not allowed to change at will, each change is very formal, must be issued a process change order, after several levels of signature, first change the cellophane bottom map, and then use the changed cellophane base map to blue, and then replace the process card of the processing site, replace it with a new process card, and replace the old process card also needs to be archived and preserved.

This is what factory E does, of course, for mass production, Tianfeng Technology is also so strict operation, which is based on the strict nature of aviation products, and has long had a set of rigorous process management processes.

The white paper process specification just now completely subverted this process management process, obviously did not issue a change order, and directly changed it with a pen, no wonder Yu Guoliang reacted so much.

After Zhang Hongzu looked at the white paper process regulations a little, his tone was very formal, and he said slowly: "Mr. Li, I want an explanation." ”

If you hadn't seen 'Industry 4.0' just now, according to Zhang Hongzu's temper, he would have directly drawn a conclusion, where would Li Tianfeng be given a chance to explain.

Li Tianfeng also said more formally: "Expert Zhang, Expert Yu, the 'TFWZ001' turboshaft engine is a new type of turboshaft engine we are developing......"

Hearing this, Zhang Hongzu interrupted Li Tianfeng's words and asked eagerly: "No, Mr. Li, are you saying that you are developing a new type of turboshaft engine, a complete engine, instead of the turbine disc just now?" ”

Li Tianfeng said: "The turbine disc just now is just one of the parts of our new turboshaft engine, and the turboshaft engine we are developing is tentatively called 'TFWZ001' turboshaft engine, with an output rated power of 1800kw and a power-to-weight ratio of 9, using a variety of new processes and new design ......"

After listening to Li Tianfeng's introduction, even Zhang Hongzu, an old expert who usually had a stern face and a smile on his face, was moved and surprised.

Output rated power 1800kw!

The power-to-weight ratio reaches 9!!

Adopt a variety of new processes and new designs!!!!

……

After a long time, Zhang Hongzu came back to his senses and said to Yang Xianfeng next to him: "Mr. Yang, how is this turboshaft engine of Tianfeng Technology compared to your turboshaft C engine?" ”

Yang Xianfeng said with a modest face: "Expert Zhang, our turboshaft C engine is at least half a generation worse than the 'TFWZ001' turboshaft engine, and the turboshaft C engine has many problems in its design, so far it has not been able to be mass-produced. ”

For the turboshaft C engine, Zhang Hongzu didn't know anything, he asked just now, just because he was too shocked and excited, after listening to Yang Xianfeng's words, Zhang Hongzu's heart was full of emotion.

"Mr. Yang, the turboshaft C engine is known as the top pillar of the domestic turboshaft engine, and it is also the hope of the turboshaft engine, but I didn't expect that Tianfeng Technology's 'TFWZ001' turboshaft engine is more advanced."

Turning around, Zhang Hongzu said to Li Tianfeng: "Mr. Li, if your turboshaft engine can really be successfully developed, we aviation people should also raise our eyebrows, Mr. Li, what support do you need, you can contact me in the future, I can still say a few words in the Commission of Science, Technology and Industry for National Defense." ”

Hearing this, Li Tianfeng was overjoyed and happily held Zhang Hongzu's hand tightly, "Expert Zhang, I will definitely trouble you in the future." ”

Li Tianfeng knew that if the 'TFWZ001' turboshaft engine was successfully developed, the future design finalization, airworthiness certification, production license, etc., would have to go through the Commission of Science, Technology and Industry for National Defense.

As an old military industrialist, Zhang Hongzu knows the hardships of aero engine development, and thinks about the hard years when he was on the front line of the aviation industry.

As such an advanced aero engine, Zhang Hongzu must be able to help as much as possible, so he made a promise just now.

At this time, Zhang Hongzu was very happy, and even had some expectations for the 'TFWZ001' turboshaft engine, and he would definitely pay attention to it from time to time in the future, but in addition to being happy and joyful, Zhang Hongzu still did not forget his own work.

"Mr. Li, what's going on with this blank paper process procedure?"

Although he asked like this, a discerning person could see at a glance that Zhang Hongzu's tone was very calm at this time, without any dissatisfaction, let alone the meaning and tone of questioning.

Li Tianfeng hurriedly explained: "Expert Zhang, that's the case. Aren't we developing the 'TFWZ001' turboshaft engine, these blank paper process regulations are all the parts processing process specifications of the 'TFWZ001' turboshaft engine......"

Li Tianfeng explained in great detail, it turned out that only the parts processing of the 'TFWZ001' turboshaft engine used the white paper process specification, and the process technicians were allowed to modify the white paper process specification, and some problems found in the processing process, some of the places that need to be improved and perfected are recorded on the white paper process specification.

After all, as a new turboshaft engine, the processing of parts is also the first time, even if the process specification is very detailed, it is inevitable that there are some shortcomings, which requires the accumulation of processing experience in the actual machining process.

After the preparation of a part processing process specification, issued to the processing site is such a whole process specification, the competent technician tracks the processing situation throughout the process, each process is tracked, and the problems in the processing process, including more appropriate process parameters, more reasonable process steps, are all recorded one by one.

After the processing of the first batch of parts is completed, the process specification is refined and improved according to these records, and the process specification is upgraded from the first version to the second version.

The second edition is certainly more advanced, more scientific, and more detailed than the first. After the second batch of parts are processed, there is a third edition, and after the third batch of parts is processed, there is a fourth version of the process specification, until there are almost no problems, and the process specification can be finalized, and the hair can be sunned.

Suppose that the first edition may have a hundred large and small problems, after upgrading to the second edition, there may only be twenty or thirty questions, after the third edition, there may only be a few questions, and after the third and fourth editions, there will hardly be any more problems.

After listening to Li Tianfeng's explanation, Zhang Hongzu's eyes lit up, and he said in his heart, smart, such an operation, several rounds of parts processing, the process regulations are very perfect and scientific, according to such a perfect and scientific process to process parts, the processing quality of its parts must be very, very good.

Yang Xianfeng's eyes also lit up, and he thought in his heart, such a good method, why didn't I think of it, no, after I go back, I must immediately refer to this method to promote it in the entire E factory, and all new models will be operated in this way.

Yu Guoliang was also impressed, and even cast a "you cow" look at Li Tianfeng.

However, Zhang Hongzu is an old expert, this method is good, but it is not consistent with the quality management procedure.

So, Zhang Hongzu said with a somewhat solemn face: "Mr. Li, this method is good, but there is a suspicion of violating the quality management procedure." ”
