Three Kingdoms: I, Liu Adou, don’t need anyone to support me

Thirty miles outside Luoyang City, there is a research institute here.

And Huang Yueying was appointed director of the institute. Among them, there are three departments, one of which is the design department, the second is the mechanical department, and the third is the trial assembly department.

The three departments work closely together, but the most important is the first one.

There are only ten people here, but each of them is a particularly awesome carpenter boss who is selected from all over the country!

Not only are they proficient in various Hayabusa structures, but they are also able to make certain improvements based on the skills passed down from their ancestors. Among these ten people, it was led by Huang Yueying. Spend all day studying the engine that Liu Chan proposed a year ago!

Although Liu Chan gave them a lot of drawings, principles, etc., if they really want to fall on the stone and develop it, they still need to continue experiments, constantly adjust the numbers, and so on.

Among them was an old man with gray hair, but his eyes were bright. A month ago, he finally finalized a version of the drawings.

Subsequently, some tools were manufactured after processing in the smelter.

And today, these structures, components, are all installed!

The old man asked people to start adding charcoal to it, and then began to boil water. As the water boiled, a very simple cart 24 began to move slowly.

Although the speed was slow, the car was able to move, which showed that their method was correct.

Everyone was very excited when they saw the car moving.

"Mu Lao, look, this car is moving, this car is moving. It's so good, it's great, it's been a year of hard work, and this thing can finally move! The dean would be very happy if he knew. Hey, you see, it's getting faster and faster. Hehe, in the future, when this thing can be mass-produced, we don't have to ride horses all day, just drive our car, and it's fine. "

"If Your Majesty knew about this, I don't know what the reaction would be. To be honest, although we are the top craftsmen in China, compared to Your Majesty, we are too far behind. Without these principles and the structural diagram he provided, we would never have thought of using water vapor to drive the car forward, even for a lifetime. Your Majesty's observation is worth learning from. "

"Alright, don't talk about Your Majesty. The car we are building now is just an experimental product, and it may take a lot of time to really take shape. You old guys, don't get too happy. Your Majesty said that this thing is very dangerous, and water vapor can easily burn people. So in the end, it will only be applied to the person who is called the train. As for cars, other fuels have to be used. But that's all for later, and while it's good that this thing can move on its own now, it's also very important that we have to deal with the speed of the thing and how to control its stop. "

As soon as the white-haired old man finished speaking, the car that had just run not far exploded, and the boiling water scattered in all directions overflowed.

And set off a large cloud of water vapor.

Thankfully, they had already prepared the others and left the test site before the experiment. There were no injuries.

But even so, the white-haired old man was still frightened.

When the water vapor was completely gone, they hurriedly went to check the situation, and they didn't understand why this was happening.

There is basically only one reason for the explosion of the water tank, and that is excessive pressure.

However, these pressures will push the shaft to move, which will drive the car to drive.

But why this is the case, it requires them to make a very accurate judgment.

Everyone looked at the fragments of the water tank all over the ground and couldn't help but fall into deep thought.

Someone suddenly said: "There should be no problem with the propeller shaft, then the problem should appear in this tank." Is the tank too thin? "

"It's possible, but the thickness of the tank we made is already larger than the thickness of the domestic kettle. If this happens, there are likely other reasons. "

"What could be the problem? Are we going to separate them for experimentation? "

Just when everyone was puzzled, Huang Yueying appeared in front of everyone.

She looked at the mess all over the ground and said, "It's not the problem of the water tank, it's the problem of the propeller shaft." "

Saying that, Huang Yueying squatted on the ground, looked at the transmission shaft carefully, and then dialed its gear movement.

After everyone saw it, they were very puzzled, and they didn't understand what Huang Yueying was doing? (Read violent novels, just go to Feilu Fiction Network!) ）

If there is a problem with the propeller shaft, it will inevitably fail to move. But the current situation is that the drive shaft can operate normally.

And just when everyone couldn't figure out the situation, Huang Yueying suddenly turned the gear in the opposite direction by half a turn. Then he turned forward again, and at the same time, his ears listened carefully. Soon, she said, "When the gears were running here, there was a lag. "

There is stuttering, but it doesn't make a difference?

But Huang Yueying continued to operate, and then, this jam became more obvious.

After a few times, the shaft could not be operated by manpower.

Huang Yueying said: "It should be that the gears are not precise enough, and this kind of thing needs to be constantly rotated to reflect." Therefore, we must make this gear accurate, at least to less than one percent of an inch, and it should be able to operate normally! "

"Dean, but 940... We don't have fixed tools, and we have limited things to see with the naked eye. So...... What can be done to make a more precise gear? "

"Your Majesty said that there is a thing among the people, called calipers! It is said that this thing can be accurate to one-fiftieth of an inch. If we... Wait, Your Majesty seems to have said before that one inch is not suitable for the current unit of measurement, because its accuracy cannot be accurately measured. So, he said, it would be best to recalculate a unit of measurement and make it into something like a ruler. If this is the case, then it is necessary for us to determine the unit first. "

Huang Yueying didn't care about these things at first, because their craftsman skills could reach the point where the seams could not be seen with the naked eye.

This is already very clever for them.

But Liu Chan said that being invisible to the naked eye does not mean that he is really tight. Then, he took a magnifying glass, and under the effect of the magnifying glass, he could see a very small gap.

This kind of gap has no effect on the general building.

However, in precision devices, it is very important.

But she thinks it's redundant and completely unnecessary.

And now that the experiment has failed, it can only prove that her idea was wrong. So, now they have to deal with the measurement thing first.
