"Passengers, please follow the instructions of the staff, find a safe place nearby, sit down, and fasten your seatbelts, the Silence is about to take off in tour mode...... Please follow the instructions of the staff......"

The Silence's announcement was repeated over and over again, and the guests on the tour were seated in their respective seats as instructed.

But before they sat down, they had already found the best location for sightseeing.

The Ellis family found that the staff did not ask them to go back indoors, so they stayed on the first deck.

Ellis's wife and daughter looked around expectantly, wondering how the Silence had taken flight.

And Ellis, in fact, has been thinking, is there any way to make a ship more than one hundred and forty meters long fly?

The first part of the promotional video "how・we・do" released by the lazy god department only talked about the weight loss part, and did not mention the other part of the "engineering" aspect.

But after all, the Silence is a behemoth of thousands of tons, and Ellis estimates with his professional vision that the current Silence has a net weight of about 2,000 tons.

So, what kind of engineering miracle is needed to make a 2,000-ton behemoth fly?

"Dad, how will the Silence fly?" asked Ellis's daughter, looking around excitedly, tugging at Ellis's arm.

Growing up, Ellis's daughter has always worshipped her father as an idol, because since she was a child, she never seemed to encounter something that her father didn't understand.

At this time, Ellis did not disappoint her.

Science is all connected, and if you want to make something fly, there are only a few solutions.

Ellis thinks it's most likely two of them:

One is to use air buoyancy, such as airships, hot air balloons.

One is the use of aerodynamics, such as airplanes, rockets.

If it is the use of air buoyancy, the largest aircraft ever built by mankind is the Hindenburg airship, which is 248.6 meters long, 41.4 meters in diameter and has a maximum take-off weight of 463 tons.

Even the famous Titanic is only 18 meters longer than it.

Since the crash of the Hindenburg airship, announcing the end of the era of human airship aviation and the beginning of the rise of airplanes, the largest aircraft built by mankind is only one-third of its length.

If the Silence wants to fly, it will use at least four to five times as many airbags, which will require at least 2 million cubic meters of hydrogen, and if it is about the same length as a zeppelin, the maximum diameter will be more than 100 meters!

It's a flying rugby!

But this is still the easiest, because if the Silence wants to fly aerodynamically, it needs at least 30 Airbus 380 engines! Its wing area must also be several times that of the Airbus, and the rigidity of the wing is required to be more than 20 times that of the Airbus 380!

Either of these two methods is beyond the current level of technology, but if Ellis is allowed to choose a direction to break through, the only direction he can choose may be to use the buoyancy of the air.

Because of the former, it is possible to invest billions of dollars and study for more than a few years, but the latter is ...... Completely impossible.

The capacity of air transport in the thousand-ton class, which is a completely unthinkable field for mankind at the moment.

"So, I guess Lazy God Technology uses the principle of airships to fly. "Of course, I believe that Lazy God Technology is bragging." Because it is almost impossible to use air buoyancy to make thousands of tons of things fly. ”

"If it's bragging, I'm afraid it's too late to brag now. Ellis's daughter said, her eyes shining: "Speaking of which, Lazy God Technology is really powerful!"

"Your erudition is amazing. Ellis's words also attracted the attention of several tourists in the neighborhood, who were probably from the Middle East, with a headscarf and a beard, but spoke English very fluently, in a round, American accent.

Ellis couldn't laugh or cry, he didn't mean to praise the Silence!

Who wants to advertise Lazy God Technology!

But even the crew members standing nearby looked at him with admiration and said, "You must be a learned professor, you are right, we do use air buoyancy to fly." ”

"I don't believe it. Ellis thought of the principle, but he couldn't believe it.

Since the wreck of the Zeppelin Hindenburg, the airship has withdrawn from the stage of history, and all technology and related research have been mothballed and stagnant.

All the products in this world that are beyond the ability of a single person are, in the final analysis, the crystallization of the industrial chain.

Even if it is the accumulation of technology for decades or hundreds of years, it is impossible to make better products without an industrial chain at all.

The best example is that there is now a company working with the U.S. Army that is developing a new generation of airship, which is only more than 70 meters long, only one-third the length of the Hindenburg, but it is the largest flying object in the world!

Moreover, because of its ugly appearance, it looks like a butt, so this airship, as it is jokingly called, is a flying ass.

History is advancing, but some technologies are not necessarily advancing, maybe they are still regressing.

For example, as early as the beginning of the last century, quantum mechanics and relativity were born, and now, quantum mechanics and relativity are still high-end theories that ordinary people cannot understand.

In Germany at that time, there were many black technology-level technologies, such as flying airplanes on zeppelins and flying as real aircraft carriers......

And Lazy God Technology, it only took a week to transform the Silence into such a thing, and it can still create a flying airship?

That's impossible!

Under the basic physical laws and the constraints of the industrial chain, how can Lazy God Technology do this?

Hearing Ellis say this, the crew laughed, and he stretched out his hand to the top of his head, only to see that something white seemed to come out of the top of the Silence, and gradually inflated like a giant balloon.

With a slight sound of air currents, the balloon grew larger and larger, gradually obscuring the entire hull.

A few kilometers behind the Silence, there were several planes chasing the Silence, and some reporters who did not board the Silence rented some private jets at a high price, and at this time they were looking down on the Silence from the window of the plane, and they saw the top of the Silence, like a giant blowing bubble gum, gradually blowing out an air bag.

Seeing this airbag, Ellis's eyes widened, and he asked in surprise, "Soft ...... Soft airbags?"

The speed of development of airships is very fast, and in the era of zeppelins, airbags have become hard, such airbags can withstand higher speeds, are stronger, and safer, and directly eliminate soft airbags.

If it was a soft airbag, how could it be possible to lift the 2,000-ton Silence!

But the facts never change for someone's disbelief.

The huge airbag on the top of the Silence inflated rapidly, inflating at an alarming speed, and the Ellis family and many more guests stared at the huge balloon in the sky that was gradually inflating, and then before they knew it, they suddenly noticed that the sound of water brought by the Silence began to fade away.

"Slowed down...... Still is...... Fly...... Flying?" Ellis looked up at the airbag in the sky, lost in his soul.

And at this moment, the whole ship broke out with a cheer almost at the same time: "It's time to fly!"

And on the planes that were chasing after the Silence to shoot, there were also reporters who cheered: "It's about to fly!"

At this moment, all kinds of cheers were heard on the broadcast screens around the world.

Not only because the take-off of the Silence is a technological subversion, but also because this scene is really beautiful.

This is the southern hemisphere, and the Silence is traveling from south to north, just in the direction of the sun, and it is photographed from the plane behind it, and the whole of the Silence is bathed in golden sunlight.

A huge, cigar-shaped airbag gradually stretched out, suspended above the Silence, connected to the upper part of the Silence by several thick metal support structures, the white airbag showed a transparent crystal color, and it could not even completely block the view, and through the airbag, you could see the Silence and the sea below.

When the sun shines, it looks like a giant soap bubble blown out of the trumpet.

The silver-gray Silence, with white edges and a huge transparent airbag in the center, looks like it came out of a fairy tale.

Driven by the airbags, the Silence became farther and farther away from the water, and the entire Silence was slowly lifted out of the water.

The water flowed down from the bottom of the Silence, and the sea seemed reluctant to let the Silence leave, and the surrounding waters were tumbling to re-wrap the Silence in it.

But the Silence rose steadily, revealing the vents below the waterline, the tail rudders, the graceful keel, the smooth bow and the alienated ball.

The Silence, which is soaked in seawater, reflects the sunlight and shines brightly.

At this moment, I don't know how many people can't help but sigh: "It's so beautiful......"

The Silence does not resemble a ship in the middle of the sea, its waterline is still graceful and smooth, and when it flies, it looks like a leaf flying in the sky when viewed from below.

A silvery leaf encased in a soap bubble.

"Flying, really flying!" Ellis's mouth opened, half shocked, half relieved after incomprehension.

Sure enough, lazy technology is lazy technology, and this kind of almost impossible thing has made them do it.

And he can be regarded as dead-hearted.

Although Ellis hated and resented Lazy God Technology, it was much lighter at this time. The Earth Warriors got the order from the United States, and he had already received his own reward, but he was still not convinced. He held back his strength, exhausted his ability, and gave the Silence a problem.

But now, Lazy God Technology threw the answer in his face.

"You're Mr. Ellis?Mr. Ellis, who got this legendary ticket?" The two Middle Easterners sitting across from him whispered something, and suddenly showed a sudden look, and one of them said, "I also want to thank you, Mr. Ellis, if it weren't for your persistence, I'm afraid we would have missed this miracle." ”

Ellis didn't even know what to say, he just felt his face hurt and he was being beaten.

"Of course, my dad is the best. His daughter didn't understand his embarrassment at all, and was still proud.

Ellis could only smile wryly.

"I'm going to bid for a ticket to the next Legend Cruise, where do you think I should be targeting?" the Middle Eastern man asked Ellis in a rare polite and low-profile manner, "The Silence can fly, nothing seems to be stumbling them?"

Ellis didn't know what to say, yes, the Silence was even flying, what else could stump them?

"Dear passengers, I am Lu Xingcheng, the captain of the Silence, the Silence is about to start accelerating, please stay in your seat, if you can, please hold on to the armrest of the seat, the Silence is about to accelerate, three ...... Two...... One ......" a steady male voice rang out over the radio.

The top deck of the Silence is where only the Silence's important personnel can go, and this is where the bridge is located, the center of the entire ship.

Lu Xingcheng stood in front of the huge glass curtain wall, unable to hide the excitement in his heart, and all the crew members took a deep breath and waited for Lu Xingcheng's instructions.

After Lu Xingcheng counted to one, one of the crew members suddenly pushed down another putter at hand.

The push lever on the left controls the Silence's underwater propulsion system, while the one on the right controls the air propulsion system.

"Boom!" a low roar sounded, and behind the Silence, four thick flames suddenly erupted, driving the Silence forward and flying wildly.

"Distinguished passengers, the Silence has taken off, and you can now leave your seat and move freely, but please do not poke any part of your body out of the hull......"

The Silence's flight was very stable.

Flying with air buoyancy is the most stable way.

Stability is like stopping on land.

In fact, ships of several thousand tons are no longer very afraid of storms, and those tens of thousands of tons of giant ships of human beings are stepping on tropical storms like gentle wind and drizzle.

Not to mention, the weather is excellent today.

From the island of Madagascar, to Dar es Salaam, to Mount Kilimanjaro, the Silence has been moving at almost a constant pace.

The Silence didn't fly very high, and seemed to be deliberately kept at an altitude of about a thousand meters.

Occasionally, the Silence would break through some of the underlying clouds, and at all times, Ellis's daughter would cheer to her feet and run around.

At this time, the Silence was semi-enclosed, with transparent glass curtain walls on all sides of the hull to block the howling winds.

Even with the engine's acceleration, the speed of the Silence was still not too fast, probably only a little faster than the speed in the water, about four or five hundred kilometers per hour. (To be continued.) )
