"According to the data we determined yesterday, I reported to the director, and the director has agreed, and everyone can make the official design in the next few days." A large pile of draft paper for calculus was placed in the corner of the wall.

That's right, although the design of aero engines is some complex calculations, it should have been computer-aided design, but at this time it is really difficult to want a computer, and the entire base is only a few DJS-130 series computers finalized in 74, and the computing speed is 100w, and the input and output method of paper tape punching is still used.

Although the computer is very backward, it is also a treasure in the entire base, and it is almost impossible for them to use this non-professional project like Yang Hui, so the hardware is really lower than the normal average of the base.

So at this time, it's still a large-scale crowd tactic, and manual calculations can still be calculated for these college students, and it's really impossible to find the director to coordinate.

"Team Leader Yang, how do we start this design, which part to start with, there should not be many parts of this engine, and it is still too late to design one by one." Pan Wen sat on the chair and asked after tidying up the table.

In terms of specific design work, Yang Hui is also thinking about how to carry out it, of course, the project team is more than enough to carry out one part by one, but it will take a long time to finalize it in two or three months, so this plan will be given up.

Then the remaining plan is to split the entire engine into several parts and assign it to everyone to find their own way to design, but this disperses the research and development force, so this plan to play a role is only to finally mobilize the various professional departments to start together and help design together, but this thing does not seem to have been announced, so it is a little difficult to implement.

"This problem, I think it's better to assign it to everyone, so it's faster, and you can't catch up with the progress of tackling key problems one by one together."

In any case, Yang Hui still made up his mind to directly distribute the launch, and implement the production package to the people, if there are people below who want to ask for help from various professional departments, it is still okay, after all, there is nothing to do in the institute now, and it is not impossible to find something to do.

As for the matter of the model aircraft that has not been officially announced, it is good to let the director say it, after all, this matter cannot be kept secret, what big secrets can there be in a house, and there should be no problem with the design of this model aircraft project, and the biggest problem and risk is the production link.

The method proposed by Yang Hui is still immediately apparent, after all, the dispersion of scientific research forces is easy to see, and the project team has the most serious problem.

Long Derong took the lead in asking, "This, it doesn't seem to be very good, the whole project team is just a few people, and it is a little difficult to disperse, so it's better to tackle the problems together." ”

You can't blame Long Derong for being conservative, after all, this project is assigned to the project team, and the institute didn't say that it could borrow the strength of other departments, Long Derong still didn't expect this.

"Don't worry about this problem, when you get your own sub-projects, you can go to the relevant departments of the institute for help, now there is nothing to do in the institute, we can still find someone to help, and the director should help us say hello to other departments first."

Finally solved this problem that everyone is concerned about, the people below are relieved, all nodded in agreement with this method, after all, it is better to be responsible for a sub-project alone than to tackle key problems together, familiar with a sub-project and continue to deepen this is a common practice of aero engine research and development, after all, an engine involves too wide a range, and it is almost impossible for a person to be all-round.

"Then do we have to determine the interface size of each component first, so that we can match it when the time comes." As a child of the base, he grew up in a factory environment since he was a child, coupled with the systematic study of the university, the questions raised by Zhong Jianshe are often to the point. The interface size he raised is also what Yang Hui wants to say.

"We need to finalize this issue now before we can split the sub-projects into pieces."

Take out a blank piece of paper, ready to record the size set below, after the parts of the engine are split, some sizes are nothing more than some hole shaft connections, keyway connections, impeller mortise and tenon connections are now to be reduced, later generations of large thrust axial flow are developing towards the integrated impeller, not to mention the small engine with the model aircraft that is not strictly required now. After all, it is too much to make so many parts for such a small engine, it is too troublesome, and the centrifugal impeller and turbine are directly integrated.

"Well, let's determine the size, like this spindle should be subjected to a very high speed, high speed leads to high temperature, the spindle must have a certain expansion when heated, as a high-speed rotation of the two fits, it should be better to choose a gap fit."

Nodding his head, he agrees with this statement, but there is no need to do it so finely now, and the tolerance will be done when the production process is finally determined.

"Well, this is a matter of experience, let's go on, and then determine the nominal size, this is the main thing now, and the tolerance to cooperate with these problems has to be done last." Yang Hui didn't even move his pen, and there was no need to remember some irrelevant data now.

I took a herb and handed it to Xie Lianfa next to him, "Come, you can calculate how much cross-section we need to use SUS304 stainless steel according to the maximum thrust and speed of our series of engines to ensure strength." ”

After listening to the instructions, Xie Lianfa immediately got up and went to his desk to calculate, calculating these things is not a mathematical problem that can be calculated directly, and the problems in the calculation of specific engineering mechanics are indispensable to check the table, and the properties of various materials are also very different. Pick up the pen and start calculating, without raising your head, this is the way to start working, this is the atmosphere that scientific research institutes should have.

"Leave that alone, it's going to take some time to figure out this problem, let's move on to the other issues, take a look at this receiver, it's ··············"

"yes, that's it." Yang Hui jotted down the data and continued to dive in.

"Okay, that's it, it's calculated, the dimensions are all here." I took the scratch paper full of all kinds of dense calculation processes directly, and it seemed that I was in a hurry, but this sense of accomplishment after solving a problem was indeed incomparable, and Xie Lianfa was also able to be excited.

Find the final result in a variety of letters and numbers, and you can see at a glance whether it is correct or not, and the error of moving the data in this kind of engineering is relatively obvious.

"Well, yes, according to the data just now, it should be this data, but in the end, this axis must be a stepped axis, and now this data is not enough, and when the data is calculated, you can roughly calculate the complete size data according to the mechanical properties of the material."

Seeing that other people were also burying their heads in calculations, and Yang Hui also had several pieces of scratch paper full of calculated data in front of him, Xie Lianfa smiled and responded. "Well, it looks like this is the stepped axis, I knew it when I did the math just now."

"Okay, you go over and wait, I'm still a little bit unfinished here."

After speaking, Yang Hui continued to bow his head and calculate, in fact, Yang Hui is still not as fast as others to calculate, he himself is very keenly aware of it, seeing that everyone else has calculated it, he doesn't want to continue to calculate.

Finally, Yang Hui was the last to calculate, but the time difference was not big. I have to sigh that I really don't adapt to not having a computer at all, and it takes so long to just have a little bit of data.

This computer really degenerates people, it is really harmful, but now give him a computer, Yang Hui will still use it, after all, this is the trend in the future, and its benefits are too much, you can't use it because of a little disadvantage, and this can't be considered a disadvantage, after all, it is to liberate the productive forces.

After collecting all the data and checking that there is no problem, copy another copy of the data that Xie Lianfa needs and hand it to Xie Lianfa, and continue to improve the data of the spindle.

"Okay, these basic data are out, come to Pan Wen to take these data, calculate the position of the oil inlet of the final combustion chamber, Zhong Jianjian, you ··············· this"

After arranging, Yang Hui found that in the end, he didn't need to calculate anything else, because several dimensions had been calculated, or had already been calculated.

I had no choice but to sit on the side and sort out all kinds of data that had been calculated for easy viewing.
