Originally, Zhou Yan was just a "juror" and watched from the sidelines while the expert team reviewed.
But as the review came to an end, Zhou Yan also became busy: the process and construction drawings of the Jinchang ultra-high-purity hydrogen fluoride, or electronic-grade hydrofluoric acid project jointly invested by Qingyan and Xinghan, had been completed.
The silicon used in semiconductor chips has a minimum purity requirement of eight to nine to ensure electrical performance during nanoscale processing. The purity of hydrofluoric acid used as an etchant is also of the same level.
The acceleration of ultra-high-purity hydrofluoric acid is similar to other extraction processes, except that the temperature, pressure control, and raw material input are increased to a level sufficient to match electronic-grade hydrofluoric acid.
Of course, high-end chemical equipment needs to have a "high-end" price. It depends on whether the money in your pocket is worth spending, so Zhou Yan naturally has to pay for it.
Zhou Yan's approach is simple and crude. He builds the project in a virtual space that has begun to take shape on an industrial scale and searches for flaws in the plan through constant testing.
In order to speed up the progress of the drawing review and work together, Zhou Yan asked Deng Zhuo and Xu Chongsheng to invite professors and experts from relevant majors from major universities in the capital to participate in the joint review of the drawings and materials.
In terms of the electronic grade hydrofluoric acid industry, small business is the first level, and the electronic grade hydrofluoric acid industry involves a large industrial base, and generally countries with incomplete industrial categories cannot succeed.
Moreover, hydrofluoric acid is involved in the chemical industry. Whether the design indicators can be achieved, equipment is a key factor, and the actual operation is also very important.
Therefore, Zhou Yan does not have to worry about technology leakage at all.
The review of the drawings was placed in the conference room of the Qingyan Group headquarters, and while the experts were reviewing the drawings and materials, Zhou Yan was busy building building blocks in the virtual space.
Although many years have passed in the space, in reality, it was only a moment. None of the experts present noticed that the "Party A's dad" who was responsible for the review had become an expert in precision chemical construction and operation.
The layout of the device is unreasonable, the degree of automation of the DCS system is not enough, there are too few interlocks, the accuracy of the instruments is insufficient, and the design margin of the pressure-bearing equipment is insufficient...
Although Xu Chongsheng had always known that Zhou Yan was a "growing pervert," he was still shocked when he discovered that the list of questions submitted by Zhou Yan was almost exactly the same as that of the expert group.
Because he was worried about scaring Xu Chongsheng out, Zhou Yan did not dare to reveal the process operating procedures for electronic-grade hydrofluoric acid in the virtual space...
The joint review of the electronic grade hydrofluoric acid drawings is coming to an end, and the aerospace engineering project has ended.
As a "landlord", Zhou Yan naturally had to attend the summary meeting with Xu Chongsheng.
Qingyan Airlines' "Tianzi No. 1" design naturally does not have major design flaws, but there are some small differences that are slightly different from national standards.
After the expert review was completed, the design was basically finalized. A few days later, Qingyan Aviation's "Tianzi-1" had an official code name, Turboprop-12.
Although the finalization of the design means that the long journey of thousands of miles has been completed, the subsequent production and testing of the test machine are the top priority.
After the design of the engine's processing technology is completed, the process department of the design department has completed the preparation of the processing technology and participated in the design review together.
After completing the design review, the parts can be processed according to the process regulations and the engine can be assembled.
Although the Qingyan aviation processing plant has not yet fully recruited technician-level workers, it is enough to process turboprop engines.
Moreover, the teachers in the workshop have already processed a batch of sample parts. After passing the test, they can directly participate in assembly.
When processing parts, there are high-precision machine tools, and even intermediate technicians can ensure accuracy as long as they follow the process flow.
When it can be assembled, "level eight workers" are needed.
Turbine impellers need to ensure dynamic balance performance. Although everyone knows that the strategy of placing the same weight on the circumference can ensure that other blades are not affected by weight deviations. In addition to simulation calculations, a lot of assembly experience is also required.
Moreover, the "weighing" and high-precision "hand-rubbing" of the "eighth-level workers" who are able to distinguish a few tenths of a gram or a few microns are of great value during assembly: it is a little closer to the simulated weight, and it takes a few
Rub it with thousand-grit sandpaper and weigh it. The weight is just right.
In just five working days, Qingyan Aviation has completed the trial production of six turbofan-12 engines and submitted them to the Aviation Test Institute for subsequent performance testing.
After that, it’s a long wait. Just for the reliability test, there are 5,000 or 10,000 hours of waiting. Qingyan has set up a temporary technical service team to prepare spare parts and "wait" for the test.
Now, others have to be busy with other things...
"Afternoon, new project mobilization meeting!"
The employees of the Qingyan Aviation Technology Department were very excited after receiving the news: the turboprop-12 has just entered the testing stage, and a new project is coming!
Of course, the designers of the fuselage and other departments also have a little expectation: the turboprops have been launched, and at least they have an fuselage to satisfy their cravings. They are getting a little tired of working on small drones every day...
So, after going to work in the afternoon, technicians from the aviation development department, airframe department, electronic control department, and process department all came to the company conference room with great expectations.
The bosses in the front row of the company didn't keep everyone waiting for too long. As soon as they arrived at work, they came to the conference room with their laptops under their arms...
"Mr. Zhou is here too. Do you have another big project?"
Everyone's expectations have become more urgent.
After sitting down, the bosses connected their laptops to the line.
"Turboprop Twelve has basically been finalized, and the process flow regulations have been put in place. All that's left is to wait for the test to be completed, get the data to improve, and start production..." Zhou Yan glanced at the friends in the audience who were looking at each other, and said,
"This, let's not talk about the same old things anymore. Since it's a mobilization meeting, we naturally have to come up with new projects."
"First, the gas turbine core of turboprop twelve..."
Many employees in the audience murmured: Isn't this old wine in new bottles?
"There are two main purposes. One is to gain a thorough understanding of the core technology of turboprops through the core machine, and the other is to change the output shaft to a rear position, that is, to change the turbine shaft..." As he spoke, Zhou Yan looked at the already a little expectant figure with a smile.
Employees, "Of course, there are two main directions for changing the turboprop to the turboshaft. One is to reduce the size as much as possible to ensure a power of 2,500 kilowatts. The other is to keep the main body size unchanged and enhance the engine power..."
Needless to say, Zhou Yan said that everyone sitting here is an aero-engine person, so they naturally understand the purpose of a small-sized 2,500-kilowatt turboshaft, Wu Zhi; and the purpose of a high-power turboshaft is even more obvious, as a heavy-duty helicopter.
After the introduction, Zhou Yan looked at the friends in the audience who were gearing up with a smile: "Although I have confidence in you, I still have to ask you, are you confident that you can do it well?!"
"Yes!" More than 300 people shouted in unison, which made the ears of all the big guys on the stage buzz.
"Next," Zhou Yan said with a straight face, "Before the meeting starts, the company office asked each of you to sign a confidentiality agreement. Is there anything you haven't submitted yet?"
After saying that, Zhou Yan glanced at the director of the company office who was in charge of recording: "Enable the clock-in function of the conference room and compare the confidentiality agreement with the electronic signature..."
At this time, many technicians realized that the highlight was yet to come...
