With the drawings, Yang Hui and Wu Dabo rushed to the factory assigned by the institute, which didn't even have a name, just a code name, so they didn't care about these little things.

I found the person in charge of the factory, explained the intention, and showed him the drawings, but I didn't expect to answer Yang Hui and the two people, "I don't look at this, you just go directly to the sheet metal workshop, your design is a stamping part, but we just help to make a test piece, so we will not do stamping dies, but it's nothing, you sheet metal workers can do it." ”

Think about it, the technical content of your own thing is so high, and it is not impossible to make it by hand in the combustion chamber. After saying goodbye, I walked straight to the sheet metal workshop I had seen when I came and went.

Before entering the workshop, I heard the sound of banging, which is a unique sound of the sheet metal workshop. A man who looks like a section leader is still dealing with a scrap item, but it looks like a problem with the measuring instrument in the end.

Seeing that the matter was dealt with over there, Yang Hui walked over to negotiate with the middle-aged man, a very talkative person, after listening to Yang Hui's intentions, he agreed with his mouth, and called Yang Hui to go to the next office area to read the drawings.

Walking into the office area, it looks rather messy, the table is full of all kinds of drawings, some are bound, some are folded, and some are rolled up, it seems that the person in charge is relatively busy.

Moved the drawings a little, opened the drawings brought by Yang Hui and spread them on the table, and a few small drawings could only be placed on top of other drawings.

"You're pretty simple, are you sure the combustion chamber is going to be like this?" It seems that this is also an expert, Yang Hui The combustion chamber they brought this time is so different from the normal combustion chamber, but in the end it was easily recognized.

Since it was recognized, Section Chief Wu simply gave a general introduction to this combustion chamber.

"Let's talk about the flame cylinder first, this flame cylinder is not too bad due to the environmental requirements, the use of GH39 alloy can be, the maximum outer diameter of 168, the length of 150, the cylinder is divided into two sections of six fuel ports, the heat capacity of the flame cylinder is 1200-6500KJ/(M^3.h.Pa), a total of three cooling air films, respectively in the flame cylinder head, middle, tail, the use of the total pressure of the corrugated ring air intake method. So these designs are relatively simple and easy to implement, you can see the second flame tube drawings for details" Speaking of his own design, Chief Wu is really talking, and there is a big meaning to continue to introduce.

For listening and reading the drawings, the workshop leader is very smooth, and when he heard that there was no speech here, he spoke.

"Your combustion chamber shell is machined, you have to go to the next workshop," he said, took out a blank piece of paper, roughly wrote down a few data, and then handed over the bound drawings to Section Chief Wu.

"I've probably written it down, now I don't need the drawings, let's go to the machine shop next door to make the shell."

This move can be regarded as a sight for Yang Hui, it is really rare to see such a skilled section leader in this base, and it is really not an ordinary worker to be able to remember the approximate data at a glance.

Since there is no need for drawings here, Yang Hui can only beckon Section Chief Wu to go to the old king next door. Not to mention, this workshop next door is really in charge of an engineer surnamed Wang. Before I entered the workshop, I heard a sentence "Wang Gong, this is done." ”

I checked the freshly machined parts with a smile, and there was no problem at all, and it was a qualified product. Put down the gauge and turn away.

"Wang Gong, we are ··········· this" It's still the old saying, introduce yourself to explain the meaning and hand over the drawings.

Put on your glasses and slowly look at the inner shell of this combustion chamber. While looking at it, he also said a few important details: "30CrMnSiA structural steel, the front installation side of the shell is connected to the rear installation edge of the casing, the two sections of the inner shell are bearing bearings, the diffuser casing is connected with the tapered support plate, and the rear end is matched with the inner hole of the guide casing support plate..."

After muttering for a while, he understood the drawings, and then he called a young man and handed over the drawings to the young young worker after giving some instructions.

"Okay, the two of you have this part is quite simple, now it is the simplest part in the entire workshop, it is no problem to hand it over to this young man, you just wait for a while, I have something to do first." Seeing that the engineer handed over the drawings to a young worker who had obviously just come to work, Yang Hui didn't know what to say.

"Is it really that simple for you to design?" Yang Hui had no choice but to ask the section chief of the later design how low the requirements of this combustion chamber were and how simple the production was.

At this time, Section Chief Wu was also more puzzled, he was designed according to Yang Hui's main body.

"This, I still design according to the general framework you gave, and finally we calculate according to the required thrust, this combustion chamber can be processed and made rougher, this is what you do." With an innocent expression, this is obviously your design is so good, you can have a large margin, you can blame me.

Full of black lines, I didn't expect my own design to be so good, this is really the first engine component I designed, I haven't done this in my previous life, but I don't have any experience, at most I just listened to people brag during the test flight.

"This is really unexpected, I didn't expect it either." If you get cheap and sell obediently, it should be what Yang Hui looks like now, but he is really underwhelmed.

No matter how surprised Yang Hui was, how satisfied he was with his design, and how bad his expression was. As time passed, the entire combustion chamber shell came out, and Yang Hui and the engineer surnamed Wang were called, and the first set of parts was accepted. The turbojet used in this model aircraft is considered a consumable, and even in the next generation, it will only be scrapped in twenty or thirty hours. After all, it is used for model airplanes, and it is cheap and not good.

Looking at this pile of guys who are still in the state of parts, Yang Hui still can't help but be overjoyed, after all, this is the first important component to go out of the design drawing in the real sense of the model aircraft project, and the future is promising.

Thinking about this, I quickly left and went next door to see if the flame barrel over there was ready, and when it was ready, I could take it and install it, and I could see the actual appearance of the combustion chamber.

Sure enough, the sheet metal workshop here is more efficient, and two flame tubes have been made, so after a brief explanation, he took away one of the finished flame tubes, and looked at this flame tube on the road, Yang Hui was insightful.

In the machining industry, each type of work has its own unique processing pattern, just take the sheet metal out of this flame cylinder, at least there should be a slight knock mark, even with a wooden hammer. But judging from this flame tube, Yang Hui can't find any traces of percussion, this is really ingenious, and I have to sigh at the superb skills of this section leader.

In this emotion, I walked to this machine shop, and there were already people in the open space at the door who began to assemble some parts, but since the combustion cylinder here has not yet arrived, it can be regarded as not being assembled.

The incendiary cartridge was handed to the worker who had just assembled it and then stopped, and the worker looked at the incendiary cartridge and began to carefully assemble it again according to the assembly drawing.

Due to the good design and large margin, it is easy to process, and it is naturally easy to assemble, and the entire combustion chamber is assembled in less than a few minutes.

looked at the real thing on the ground, and then looked at the renderings on the drawing shelf on the side, it seems that there is no problem, of course, this just looks like there is no problem, whether there is a problem with the design, and the follow-up tests can be exposed one after another.

"I see your drawings use gasoline as fuel, why don't we try it?" We have fans and gasoline that can meet the ignition requirements of this combustion chamber. ”

Seeing the eagerness of the worker who assembled the combustion chamber, although Yang Hui also wanted to light a fire here, satisfying the worker and satisfying his curiosity, the truth was not allowed. This combustion chamber is quite special, and it must be preheated with gas first, which is more troublesome, and it is obvious that there is no such thing as propane here, so it is destined to say no to this enthusiastic worker brother.

"This really doesn't work, the combustion chamber design requires that propane be used to pre-ignite the hot spot, and it is not possible to directly apply liquid fuel." Yang Hui explained helplessly.

Nima, this engine is really a pit. I'm afraid that only this sentence can describe the mood of this worker brother.
