It's another good weather, a new day, Yang Hui got up early, had breakfast, and went to his project team office early, because today is a happy day, the sub-projects of the power system are going to be drawn finally, and Zhong Jianshe re-optimized the selection of the impeller scheme to the foundry today and tomorrow to make new test pieces, these are all worthy of joy.

Xie Lianfa's shaft and bearing bearing project, yesterday has been applied to Yang Hui for verification, today to find someone to do the test piece, now Xie Lianfa is going to Liyang factory, the whole bearing base can only be done by Liyang factory.

Bearings are easy to design, they look easy to machine, and most of them are turned, but in fact they are not easy to do at all. The bearings are not simple, especially the bearings used in the turbojet, the environment is extremely harsh, and they have to withstand high speed and high temperature. The most important thing is that other parts are allowed to have a little machining damage, but the bearing of the scrolljet must definitely not have a little damage. The reason is determined by the working environment of the bearing, and the slightest problem in such a harsh environment will be infinitely magnified, and finally the machine is no longer a few.

Therefore, these harsh conditions eventually created the ultra-high technology required for the manufacture of scrolljet bearings, first of all, the turbojet bearings require high-grade alloy materials, which are resistant to high temperature and wear, and the materials are naturally quite difficult to process. As far as the wear resistance of the material is concerned, it is destined that the general machinery factory cannot do it. However, this alone is only a requirement for advanced tools and faster machine tools, and it may be possible to find a way, but bearing manufacturing is not just about you machining the shape.

The high temperature resistance of the bearing requires a suitable heat treatment process, so even if the front turning is completed, the heat treatment behind it is still there. This heat treatment is not something that can be made up for by hardware facilities, which requires many years of heat treatment experience and a lot of money to try it out step by step.

So all these reasons determine that there are few machinery factories in the Republic that can make this bearing, and only Liyang can do it in the 011 base, who makes the family so awesome.

At this time, Liu Wang dragged his tired body to the office, put the drawings on Yang Hui's desk, and said weakly, "Team leader, I made the final drawings, you can take a look." ”

After saying that, he closed his heavy eyelids and drooped his head, as if he could fall asleep while standing.

What is the situation, why has it been popular to stay up late late, why has Liu Wang stayed up late now, Yang Hui asked puzzledly, "Have you stayed up late?" What's going on. ”

This time, Liu Wang finally raised his head, and it took the boss's strength to open his eyes a slit.

"Team leader, I saw that you and Zhong Jianshe both finished the project early, and I was afraid of delaying, so I stayed up all night after finishing it, only to find that this is really uncomfortable."

What should I say about this lovely and unwilling Comrade Liu Wang, who has nothing to learn from what others stay up late to do, and the rest of his work can be done in one day today, where will he be held back, now it's okay, I have to stay up all night, it's really a crime. Sometimes it's so cute and laughable when it comes to technology.

"Okay, the spirit is commendable, but this kind of thing will be done less in the future, you will be a job that can be done in a day, and you have to stay up all night to suffer. Come on, I'll give you permission to sleep in the office at noon today, go to the back corner and sleep there, it's quieter. ”

Hearing this, it was like heaven, Liu Wang squinted his eyes, and walked to the back corner with vague steps. No matter how Yang Hui looks at it, he thinks this guy is quite cute.

Seeing that Liu Wang was lying on the table and had fallen asleep, and it seemed that there was still a tendency to be a joker, Yang Hui couldn't bear to look at it, and hurriedly buried his head in reviewing Pan Wen's design.

What a big breakthrough in Liu Wang's design, it is still relatively simple for the model aircraft micro turbojet, which is acceptable, I took a look at the main data, and then it was Yang Hui's manual review time. Began to check whether there is a problem with the answers to some calculations, whether there are errors in the drawings, whether there are errors in the labeling of the data, etc., and it took two hours to complete Liu Wang's design review, and there was no mistake, it seems that Liu Wang is a very careful person, which is a very good habit.

Then look at the other people have returned to the office one after another in the drawing, it looks like this afternoon this is going to be the rhythm of the drawing together, it looks very fast, more than 20 days can be the first drawing, although the follow-up will be changed, but these are still not easy, the first drawing takes the most time, and the back is generally a small range of modifications, unless the whole design has a big problem, otherwise it will not easily overturn a large unit, that is, a large component.

"Team leader, this is my design, you can see it and there is no problem." Pan Wen finally made the drawings before getting off work at noon, and after seeing that there was no problem, he turned to Yang Hui for review.

Sure enough, as Yang Hui expected, today is the rhythm of all the drawings, Pan Wen's turbine and deflector design were also handed over to Yang Hui for review, and Long Derong's engine starting system should also be handed over for review in the afternoon.

Calculate the time, "Okay, it's time to get off work, let's go to dinner after work." By the way, you can help me bring a few steamed buns back, I still have Pan Wen's drawings to review here, and I'm afraid that Longlong's starting system is also coming out, so I'm going to hurry. ”

Time is pressing, it is better to hurry up or hurry. If you can complete the audit today, you can do the test tomorrow, and you have to hurry up.

There are definitely steamed buns at the base, they are all people from the north, and it is impossible to do without pasta, so it is easiest to load two steamed buns and bring them back. However, it is impossible to eat white flour steamed buns, no matter how you have to add some coarse grains in it, and now the country's food is still not enough. There are other reasons, but that's the way it is.

Yang Hui was left alone in the office, and when he picked up Pan Wen's turbine design drawings, he felt ugly at first glance. A tall turbine is designed for the poor, which requires courage and ability.

Well, we don't measure the design of this turbine by its appearance, Yang Hui put the drawings aside, and looked at other design materials with design ideas and design indicators. I didn't know it, but when I looked at it, I realized that the body of this poor turbine actually contained powerful energy.

Just look at the statistics written at the end and write it unmistakably: after calculation, the turbine efficiency is 6.4% higher than the engine design requirements, you can't underestimate this 6.4, this 6.4 is definitely a huge surprise, Yang Hui hurriedly took out the scratch paper to see if there was a problem, and it was the same after calculating it several times.

This is really a big surprise, it seems that the project team is all talented, just the centrifugal impeller of Zhong Jianjian, coupled with Pan Wen's turbine design here, this small vortex is simply against the sky.

Quickly calm down the excitement and continue to review the rest of the designs, the more you look at it, the more interesting it becomes. After reviewing Pan Wen's design, Yang Hui only had one sentence: "This person is the essence of industrial design of the Republic", except for this sentence, there is no sentence to describe Yang Hui's meaning, this Pan Wen is too interesting.

Quickly gnawed the steamed buns, continued to review the design, and before the audit was completed, Long Derong's design was also released, and it was sent to Yang Hui for review, and all the designs were preliminary. It was very busy, but the final startup system review was completed by 5 p.m.

"Okay, Longlong, you are the last, several of them have already gone before, and now there is still an hour to get off work, hurry up and hand it over to the institute for review, see if you can do a good job of auditing today, and you can all go to trial production tomorrow."

Give the last copy of Long Derong's design to Long Derong, Yang Hui will be done today, and he will sit in the office tomorrow and wait for the good news.

The test was arranged, and Yang Hui was on time for the first time this time, leaving work on time, which was really a little uncomfortable.
