Daqin: Qin Shihuang Visited The Stalls At the Start

Seeing that Old Zhao was silent, Su Yu also shrugged.

Of course he knew what Lao Zhao was thinking.

It is nothing more than the use of hydrogen as the floating gas of the airship, whether it is safe or not.

Indeed, the gas used in modern airships more than two thousand years later is helium.

However, the purification methods of helium such as natural gas separation method, synthetic ammonia method, liquefied air fractionation method, and uranium ore roasting method.

These craftsmanships are far from what the current Daqin can achieve.

Even with Su Yu's knowledge, there are some deficiencies in materials, utensils, and facilities.

Even though the content of helium in the entire universe is extremely high, it accounts for as high as 24% in the Milky Way.

However, it is difficult to extract it, and the current Da Qin can only look at it greedily.

As for hydrogen, it's really dangerous.

Even in the 20th century when airships were prevalent, there were many accidents caused by hydrogen explosions.

As a result, airships were gradually replaced by planes that appeared in the sky.

But it is undeniable that, in all aspects, hydrogen is indeed the best choice for Daqin to develop airships.

Also the only option.

In Europe in the Middle Ages, all airships were also filled with hydrogen.

After weighing the pros and cons, Su Yu personally thinks.

Problems like this that can be considered to be avoided should not be an obstacle for Daqin to create airships today.

Lao Zhao here is not an indecisive person.

After thinking for a while, he raised his head and looked at Su Yu again: "How much would it cost to make this airship out of hydrogen?

This time, Su Yu said without thinking: "Because the airship is a hollow structure, it does not consume a lot of materials. 99

“As for hydrogen, it can be mass-produced by directly using electrolyzed water, and the cost is terrifyingly low. 35

While speaking, Su Yu opened the system interface in his mind, and selected some structural drawings of the airships provided by the system.

"For example, a large airship with a length of ninety feet, a maximum diameter of ten feet, a body weight of 3,900 shi, and a load of 1,800 shi, may cost less than half of the Black Water Dragon.

"Huh? Why are you looking at me like that?"

As soon as Su Yu finished speaking, he saw everyone, including Lao Zhao, staring at him with a pair of eyes.

"You said... how big is this airship?" Wang Ben asked in disbelief.

Su Yu scratched his hair in confusion.

"The length is ninety feet, the maximum diameter is ten feet, the body weight is 3,900 stone, and the load is 1,800 stone."

"Hahahaha! We must make this empty boat! Su Yu, for the specific production method, Daqin bid fifty million! Old Zhao's eyes are full of excitement.

Because of the preconceived relationship of helicopters.

When he first heard the airship, he thought it should be about the size of a helicopter.

It is also good to be able to carry out a small amount of personnel transportation and information transfer.

.....for flowers...0

So there was some hesitation at first.

I don't know if such a tasteless thing is worth the great cost of making it.

That's why he asked Su Yu the cost of making this airship so that he could make a choice.

But he never imagined that the airship would be so big!

Not only such a volume, it has far surpassed the Black Water Dragon.

Even the weight has reached an astonishing 1,800 stone!

You must know that the general ships that are currently navigating the main rivers of Daqin are only 2,000 stone.

0

Only a limited number of giant ships have a carrying capacity of four or five thousand stone.

The load capacity of this airship is only average.

But the speed of its long-distance transportation, and the environment, are unmatched by any ships that rely on river transportation.

This is flying in the sky with a thing of 1,800 stone!

What's more, in his opinion, the purpose of this airship should be far more than that.

"Su Yu, if we fill this airship with fragmentation shells and drop them when needed..."

Lao Zhao did not speak further.

His voice trembled slightly, and his eyes were full of madness.

His words made everyone in the room tremble, and then they all focused on Su Yu, as if waiting for his answer.

The corners of Su Yu's mouth gradually rose.

"That's what I'm going to say, the second use of airships, air strikes!" And.
