Third, it's not easy to stay up until the middle of the night, so let's recommend a few tickets

Zhong Jianshe stayed in the test center, but Yang Hui signed and left, and the test pieces that the entire power system project team came back today are not only centrifugal impellers, but also other components.

Returning to the office and sitting down, he picked up the book again that had not turned a page at noon, Yang Hui still saw it so "with relish, intoxicated and unable to extricate himself" until the sound of footsteps kept approaching the office.

Yang Hui put down the book in his hand and looked out, and sure enough, Xie Lianfa also came back.

"I'm back, how are the test pieces?"

The spindle that Xie Lianfa is responsible for is a key sub-project, and the importance is quite high, and it is necessary to know the situation immediately.

However, looking at Xie Lianfa's black line, Yang Hui's heart hung higher again, this is a problem.

"Don't say it, the people in Liyang are really busy, looking for people everywhere, and finally made three, and one of them was scrapped. I don't know if two will be enough. ”

Xie Lianfa said this very easily, but he was not loose at all, and the two shafts were not easy to test.

The people in this Liyang factory are really, and the last incident hasn't woken them up, and now they don't even cooperate with the parts test done by the design here, what kind of teammate is this really called.

"Where is the axis? Let me see. ”

At this time, Xie Lianfa took the shaft wrapped in newspaper in his hand to Yang Hui.

Unfolding the newspaper, lying in the middle is a oiled spindle, which is greasy to the touch.

"I don't know if these two will work, let's send them to the testing center. If it really doesn't work, let the director call again, and then go to the scene in person, and you must make more than five roots in Liyang. ”

For Liyang's current attitude, Yang Hui can only endure it first, and after his model aircraft project earns money in the future, it will be easy to say that he is still rich in the end.

The problem between the factories has been going on for a long time, and it stands to reason that the machinery factory is to cooperate with the research institute's trial production task, which is understandable. But the biggest problem is that the machine factory cooperates with the research institute to produce prototype parts, and the remuneration can be said to be free. In addition, in order to cooperate with the trial production work, it is necessary to transfer elite soldiers, which is very unpleasant for the machinery factory.

Another point is also important, but it is an open contradiction between factories. There are also technical departments in various machinery factories, and the machinery factories themselves are actually engaged in technology.

Typical can be said to be the 0132 factory and 0611 institute in Bashu, when the two have not been merged into a company, it is called a tragedy, at that time 0132 was its own J-7 series aircraft, not 0611 design. If you think about the internal design department of a machine factory, the relationship between that design and the institute must not be good.

And the contradiction between the two sides broke out on a modification of the J-7, 0132 requires direct surveying and mapping, so that the technology is simple, and it can be based on our factory. However, at this time, the 0611 of Jianjiu dismounted was facing the problem of no rice cooking, so it was required to focus on 0611 to carry out independent research and development and upgrading, so as to ensure that there were projects in the institute. In this way, in the end, the director of the research institute used some means, made self-sacrifice, and got the dominance, for which the old man Tu of 0132 hated Wang Xshou of 0611 with itchy teeth.

(PS: This is not Hei Chen Fei, it's just an anecdote, just laugh and laugh.) Far away......

Came to the bottom of the office building and met again, Liu Wang came back, this guy came quite quickly, the casing and the diversion cone were relatively simple, and they came relatively quickly.

"Team Leader Yang, I'm back, and the casing and deflector cone have also been done, and a total of five sets have been made."

Apparently this guy was not only a little fast when he was a nephew, but he was probably also against the wind, and now his hair is blowing wildly, and he looks more like a wild motorcyclist.

"That's good. Let's go together, your nephew's key is still there, right? ”

Yang Hui has nothing to worry about Liu Wang's receiver and diversion cone, one is that these two things are relatively simple, and the other is that Liu Wang is more careful, and there will generally be no problems, and now Yang Hui is concerned about whether the nephew can still ride.

"I haven't returned it yet, the key is here. Where are you going? As he spoke, he gave the key to Yang Hui, and he was busy moving the things out of the side bucket.

hurriedly went over to stop Liu Wang's move. "No, no, I just want to go to the test center inside, and those who stop by will go, you can go up and do the side bucket."

Get on the familiar nephew, stand on tiptoe and press the engine start pedal hard.

The nephew was quite reliable, and it didn't take long for it to start, and a steady roar sounded.

The people in the back have already sat down, and after giving oil, the nephew slowly ran forward, and the three strong young men sat on it was still a little heavy, and this nephew was a guy who accompanied the establishment of the institute, and now it is gradually aging.

It is still good to run slower in the office, and it is safer to be slower when there are more people.

The roar along the way almost overshadowed the roar of the machines in the test center, and Yang Hui could faintly feel a little tinnitus in his ears when he was in the car.

Looking at this nephew, Yang Hui hurriedly threw the key to Liu Wang, when he went back, Yang Hui didn't plan to be on this nephew, he would rather walk better.

"Section Chief Li, we're here again."

Section Chief Li was watching the test of the impeller sent just now, where did he have time to come out to greet Yang Hui, just wave at Yang Hui.

"Here, just come here, the structural strength test of the impeller is being done here."

Before he finished speaking, he turned his head again to continue looking at the test, and at this time, the compressed air cannon used for the test fired a solid ball with a mass of 50 grams at a speed of 30 m/s at the impeller that was running at high speed.

Then I heard a bang, and then there was no more, and the impeller was broken, which was the smallest level of impact test, but this impeller couldn't stand it.

The broken impeller was scattered inside the protective cover, and when I walked in, the protective cover was already pitted, and at first glance it was a battle-tested warrior.

"Tsk, this impeller is extreme! Extremely simple, extremely fragile. Section Chief Li summed up this impeller quite well in eight words.

For this kind of thing, Yang Hui and Zhong Jianshe didn't expect to leave early, and they didn't have any surprised expressions, in fact, they didn't plan to do a crash test at the beginning, after all, this structure was placed there like that, and they became aware of it at a glance, and then they saw that there were so many impellers, so they had a luxury, and it was okay to test it.

"It's okay, Section Chief Li, we have to anticipate this, we deliberately gave up this. If you don't crash, you won't crash, and we don't plan to use this engine for manning or anything, so as soon as the model plane breaks, it will break. ”

Yang Hui walked over and said disapprovingly, you really don't need to pay too much attention to this, it's a big deal to install an anti-collision grille in the air intake when the time comes.

"That's right, you don't have to be too strict with the model airplane, it's better to relax it, if it's too leather, it's not bad to use, and your follow-up sales will not be good in the future, so it's good."

This Section Chief Li is very interesting, it is really rare to be able to think of a piece for Yang Hui, a profiteer, at this time.

Hang up on the anti-collision test and continue to ask for the following test, so that you have time to accompany Yang Hui to see where the new test piece is.

"How? Take it out and I'll take a look. Which part again. Sticking out his head to look everywhere and didn't find anything, Section Chief Li asked for it directly.

I took out the two shafts on the newspaper bag from the bag and opened them for Section Chief Li to see.

"Liyang's attitude this time is much better than before" After looking at the main shaft, Section Chief Li can see the appearance of Liyang Factory. After the last engine assembly error, it is obvious that it has learned to converge.

"Bring all the other test pieces," Section Chief Li, who didn't want to run more wrongful ways, stared at Liu Wang for a long time.

Liu Wang saw that the matter of the shaft inside had been negotiated, and he also took out his receiver guide cone and handed it to the section chief.

But it is obvious that Section Chief Li will no longer look at these two parts after looking at them twice, there is nothing to detect, the casing and the guide cone are relatively simple, first do a good job of the spindle here and then talk about it.

"There are only two spindles, can you test it?" When it comes to the number of bearings, this is something that everyone is more concerned about. Now the two spindles are a bit scarce, which is a bit worrying.

"It's nothing, we should be able to test enough, but you still have to do a few shafts in the future, let's think about what to do first"
