Chapter 848: Training Practice Course

As Wu Daguan joined the discussion, everyone turned their attention to him. Chen Yijian asked, "Old Wu, what do you think can be achieved in one year?"
Wu Da visualized it for a while, and chatted with Li Mengzhen beside him for a while before he spoke: "In the first year, I am afraid it can only achieve the original level. The localization rate of 72.6% cannot be more. The equipment and personnel are all idle. After a lot of time, it is not a simple matter to just adjust and resume production."
Tan Zhenhua sighed secretly.
This is no way. The first "Speey" localization process with the support of the whole nation has been supported by the whole country. After four engines were produced in 1980, they were ruthlessly put in the cabinet. So far, it has been three years. In three years, it was enough for the engineers who wrote the process specification to forget many details, and enough for the skills of the workers involved in its production to become rusty.
What's more, everything they had mastered was not perfect.
All this requires the accumulation of time and experience. Wu Daguan said that one year it can be restored to the level when it was interrupted, I am afraid that he has already made a relatively optimistic estimate.
Perhaps seeing Tan Zhenhua’s concerns, Wu Daguan patted him on the shoulder again and said:
But there is also good news. The first time to introduce "Speey" negotiations. After all, it is the first time for China to introduce this kind of from the Western world. High-tech products, so there are many hurried imperfections. For example, how to deal with the precision forging process of turbine blades. We actually didn't know how to do it. When we paid the money and went to Luo Luo, they took the opportunity to speak. At that time, we actually had no money to pay for this additional cost. It was very unrealistic to submit a report and apply for an upward application. In the end, we had no choice but to do it. The last four engines produced were actually assembled by Rolls-Royce. Produced turbine blades."
"What about this time?" Wang Qingping hurriedly asked.
"Old man, I can't fall twice in the same place, right?" Wu Daguan shook his head slightly proudly: "Some problems I found last time, such as this precision forging process, such as the formula and processing technology of some materials, We are discussing this time as the most important content. As the saying goes, we learn from the experience and lessons of the last time, and our negotiations this time are much more careful. Luo Luo wants to pit on these aspects again. It's not that easy for us!"
This is really good news.
As far as Tan Zhenhua knows, "Speey", an engine with international technical standards in the late 1960s and early 1970s, is actually not as complicated as the manufacturing process that China cannot master at all. It has already spent huge sums of money to purchase it at the West Air Development Plant On the basis of a complete set of the latest foreign processing equipment, it is fully capable of manufacturing. The most important thing is the processing technology and materials.
Material is the most troublesome thing. Even if you know the formula but don't know the production process of others, the performance of what you make is likely to differ from the performance of others.
In fact, after the most basic materials and processing techniques have been improved, it is really not difficult for China to imitate engines of this level of technology. In Tan Zhenhua’s previous life, in 2000, it had been interrupted for 20 years. The "Speey" imitation program was launched again, known in history as the "Second Spey Battle". This time, the Huaxia people did not receive any help from Rolls-Royce. It only took 1 year and 2 or 2 months to complete it. The first "Speey" was trial-produced. Four months later, the 150-hour test run was successful, indicating that the domestic engine has reached the technical standard. Subsequently, it was further upgraded and modified with domestic materials. Compared with the prototype, the weight was reduced from 1842 kg to 1527 kg in one breath, but the thrust was increased from 9.3 tons to 10 tons, and the thrust-to-weight ratio reached 6.55!
The new engine passed the domestic engineering technology appraisal in July 2003, and passed the design finalization review of the improved model in 2005, which is a super fast.
At this time, this engine named "Qinling" has a localization rate of 99%!
This is a huge progress, and the basis of progress comes from the accumulation of basic industrial technology in China for 20 years.
Now that Wu Daguan has noticed this aspect, that is to say, most of the problems encountered in the last processing have already been solved, which will greatly reduce the need for imitation after starting the "Spee" project again. time.
"With the supplement of these data, I believe that our localization rate can be improved very quickly. Of course, the accuracy of these data needs to be further proved by us through experiments." Wu Daguan continued: "But don't worry too much. , I believe Rolls-Royce will basically not play such tricks this time."
"Why?" Chen Yijian asked curiously.
"Because, this time the terms of the contract were made by Zhenhua’s good brother Yu Peng and Xiayu! Don’t say anything else, just the payment terms. If Luo Luo is deceived like last time , Hehe, don’t say that the remaining 15% of the balance payment cannot be obtained, and a lawsuit is filed. I am afraid they will lose their money!"
Everyone now understands, and they also have a deeper understanding of why Tan Zhenhua must have Yu Pengxia come over to review the text of the contract every time such a major contract needs to be signed.
"Then Mr. Wu, assuming that the first year is not counted, based on your experience, how much can we increase the localization rate in the second year? How many qualified engines can be produced?"
This is the issue Tan Zhenhua is most concerned about.
Wu Daguan pondered for a while, and then whispered to Li Mengzhen for a while: "When this "Speey" production line was introduced, according to the department's requirements, it was necessary to form a mainframe production capacity of 120 units/year and 400 units/year. The production capacity of turbine blades, but now, this figure is obviously not realistic. I just estimated it with Chief Li. According to the capacity of existing equipment, we can form 30-40 units in the next year. With the increase in proficiency in the future, the production capacity will gradually increase, and the annual production capacity of 80-100 units can be expected."
Tan Zhenhua nodded, then lowered his head to ponder for a while before saying: "Old Wu, I have an idea, do you think it is feasible."
Wu Daguan knows that although Tan Zhenhua does not understand engine technology, his ideas have always been from the practical perspective of solving problems, and he is very good at solving problems in some wonderful ways. Therefore, he now pays more and more attention to this kid. Views.
"Zhenhua, you say."
"I think, since we have enough engines in the warehouse, after setting aside the experimental needs of the "Flying Leopard" prototype, we can at least meet the first year of delivery from the Ipos side, and considering Mr. Chen The implementation of their modification plan and flight test needs, this time can be postponed to the second year, then we don’t have to rush into production, but can start to solve some important preparations, for example, I suggest that the team is divided into Two parts-one part is responsible for restoring the last interrupted production process while studying the newly obtained processing technology and material formula from the experiment, the other part can be transferred out to do another thing."
"what's up?"
"To work as a worker in Rolls-Royce, you must send people to every important production link and quality management link, and one is not enough, at least 2-3 people. It cannot be a pretentious visit and training. Skilled workers in the process, after doing this for half a year and a year, these people sent out will definitely learn a lot, and they will also become the seeds of our West Air Development when they come back."
"... Zhenhua, your idea is pretty good. It fits the principle of "sharpening knives and not chopping wood by mistake", but in this way, you have to send out hundreds of people. Can Luo Luo agree?"
"Old Wu, you don't have to worry about this, you just have to get the approval of the Third Ministry of Machinery, and Luo Luo has me to deal with them. I believe Sir Hook will still give this little face." Tan Zhenhua replied very confidently. Said: "After all, we have so many cooperative projects with them now, and I will not let them do this in vain. I will pay a lot of money. The capitalists even hang their noose for profit. Can be sold, let alone a small training internship tutorial?"
