Although there is already a kind of war in the entire Jiaguo, and there is an element of revenge and hatred in it, Ye Yu is still quite "leisurely".

Of course, this does not mean that he is fine in the research institute, but compared to other people who fight, he is relatively relaxed.

The shell of the airship is almost finished, the propellers on the side are finished, and the skeleton that looks like a big fish has been completed.

Now the engines are being installed one by one.

They started with large engines that powered the main side propellers.

This is followed by small engines, which are equipped with engines for the individual direction propellers and the auxiliary propellers below to prevent problems with the main propellers.

"Come here, have a meeting, report all the progress."

Seeing that the construction was progressing steadily, Ye Yu summoned representatives of engineers, craftsmen, and warlocks from all branches of the project to come over for a meeting.

"Your Highness, the entire airship is being carried out in the part of the previous reduction experiment."

One engineer said, "Now we have to deflate the airbags to reduce the weight of the air." ”

"In terms of materials, there is no problem, diesel has been refined in large quantities, and now it can basically meet the future needs of airships."

The warlock spoke.

Subsequently, other divisions also reported on the construction status.

Because they had Ye Yu's design drawings and they had tested a smaller version of the model to be able to do it, they were relieved to continue the project.

"But I'm still worried about vacating."

Ye Yu thought about it and said, "Wait until the airbag is put down, and test the flight problem first." At least on the basis of this framework, it is necessary to fly. ”

"Yes!"

After everyone nodded, they immediately went to prioritize the issue of the internal airbag.

They don't know how many airbags they need.

This is also a core test.

There are more airbags, and it costs money.

But with fewer airbags, more oil will be needed in the future.

This is the key question.

Therefore, until now, Ye Yu suddenly cared about this problem.

Two days later, the finished airbag had been fitted to a simple frame.

The whole airship basically has some shape.

It's just that the various rooms inside and the canvas on the exterior have not been added.

"The first tests began, and everyone put on their parachutes."

Ye Yu said, "It's just the right time to test the performance of the parachute. ”

He said and smiled.

After all, this thing is about the fortunes of the country, and he can't be sloppy.

Being able to fly is not the same thing as being in good shape.

Although the direction has not been set yet, and it is simply a test of take-off, everyone's eyes are quite nervous.

There was some excitement in the nervousness.

The engine turned on and roared loudly.

It's like a factory is running.

Then, according to the control, a total of six large propellers on both sides were rotated, and the surrounding wind suddenly became fierce.

With the strong wind, Ye Yu was at the front of the airship, watching them slowly rise into the air.

The speed was not very fast, but Ye Yu could clearly feel that they were leaving the ground!

"It worked!"

The engineers on board the ship cheered each other.

They climbed about three feet upward, which was almost above the height of a normal building.

If it weren't for the mountains, I'm afraid most people would be able to see it.

The ground was still windy, but when it flew more than six feet high, the ground barely felt too much wind.

Although the wind is still there.

"Your Highness, how are we going down?"

Soon the engineers were faced with a problem, which was easy to go up the hill and difficult to get down.

And now this empty structure is only equipped with large propellers on both sides to provide lift.

Up to the small propellers below are turned on to provide additional lift.

"It's still going up, it's weakening the propeller drive."

Ye Yu opened his mouth and said, "I remember telling you to keep a stall, right?" Just take advantage of this time to test the gear, go down and slowly fine-tune, a total of five gears, I need three gears is suspended. ”

"Yes!"

The engineers nodded and got to work.

Because when taking off they use five gears, the top speed.

So it's also quite oily.

As the engine weakens and the propellers slow down, they begin to descend slowly.

At this time, the role of the airbag is highlighted.

The descent is a bit slower because of the presence of airbags.

"Okay, that's it, wait until it lands."

Ye Yu looked at the second gear, and their descent speed was stable, so he spoke.

It didn't take long for only the frame of the airship to fall to the ground, and the engine was turned off.

Although there were no accidents and it was impossible to test the effect of the parachute, at least it proved that the current airship can take off easily.

"Alright, come here."

After the test, Ye Yu called all the engineers who were standing on it to participate in the test.

"Your Highness, we know that we need to adjust the flexibility of the entire engine."

"Yes, there should be a few more gears to be fine-tuned, and different places seem to require different lifts."

"And that's all about moving things up in the future, shouldn't we add a big engine?"

The engineering department was talking to each other, and then Ye Yu coughed, and they stopped discussing.

"There's nothing wrong with what you're saying."

"First of all, the gear is only temporary, adjust the speed, on the one hand, the gear of the transmission, and the operation of the engine."

Ye Yu said, "Now the speed of operation is not very fast, adding a large engine, the space should be enough, what about the engine, the amount of oil can control the efficiency of the engine." ”

"Yes!"

The engineers nodded.

"The variable layer double adjustment system, on the one hand, is the transmission shift of the engine, on the other hand, the adjustment of the oil, and then put it on a device, anyway, there must be electricity on the airship."

Ye Yu said about the adjustment after that, "In a normal state, the three large engines are all half-hung, and then the gears are adjusted." This prevents us from falling suddenly when there is an engine failure. ”

He's going to start thinking about security now.

Even if it's just a framework now, if you don't consider the security issues, the various problems that arise in the future will still threaten you!

After all, I have to be on it after all.

The engineers nodded their heads and went to calculate the follow-up problems one by one and based on the model.

Ye Yu's talents are the core of the entire research institute.

These people were a mixture of special warlocks and craftsmen who began to receive Ye Yu's "education" in the Southern Dynasty at that time.

Anyway, he said that he saw the knowledge obtained by the gods in a dream, and they would not doubt it.

So during that time, Ye Yu actually told them a lot of science and engineering knowledge.

This group of people is just a "secret that cannot be passed on", of course, it is only now, in the future, Ye Yu plans to let this group of people make textbooks, and the craftsmen and warlocks who aim to enter the research institute need to learn these "basic knowledge".
