Alchemy Greater China

Long Hao chuckled: "I knew you would ask this, well, of course I have my reasons, I will put this submarine to great use recently... Today, John, you just have to test this Qianlong with me- On the 1st, see if there are any major mistakes, if there are any, there is still some time, we can try our best to correct them."

The big flaw naturally refers to the underwater pressure resistance of the submarine. No matter how much money Long Hao has, he cannot make a leaky submarine continue to sail under the sea by himself.

Huo Lan murmured when he heard this, but he still nodded and said: "Okay, everything is up to you, Earl... It seems that the surface navigation of Qianlong-1 is basically normal, and the current speed has also increased to 12 knots, which proves that The internal combustion engine motor is working well."

Long Hao also nodded and said: "Normal surface navigation is just the beginning. What really matters is the underwater navigation. Come, Mr. Huo Lan, let's go down together!"

After finishing speaking, the two people, under the escort of a sailor, opened the hatch and entered the interior of Qianlong-1 one by one.

This time, the interior of Qianlong-1 has been filled to the brim. The parts that were missing last time have now been filled, and the white lines are no longer visible.

Today's Qianlong-1 has a displacement of 120 tons, a self-weight of 78.5 tons, and can accommodate up to 8 crew members.

At this moment, because it is a trial voyage, in order to ensure spaciousness and comfort, except for Long Hao and Huo Lan, only 3 sailors stay at their respective positions.

One is responsible for controlling the direction of travel, one is responsible for adjusting the power switch and diving up and down, and the other is the sailor who has just come down. He is mainly responsible for maneuvering (well, including excitement).

Standing behind the sailor who was in charge of controlling the direction of travel, Long Hao asked, "How about the steering function of Qianlong-1? I haven't tried it yet, so let's start the experiment now!"

Long Hao and Huo Lan were standing on the top of the submarine just now, and it is definitely not possible to try to turn or something, so at this moment, the sailor responded energetically, and concentrated on maneuvering, very quickly.Qianlong-1 started to turn.

Don't look at Qianlong-1 turning, but the inside of the boat is not affected too much. The result of this experiment surprised Huo Lan and others. Only Long Hao was determined: Just kidding, this is the result of countless tests in the future. Although the best submarine shape I created is inevitable in my hands, how can the steering at such a low speed affect the interior of the ship?

After the test, turn, and then dive.This test is the most important. Except for Long Hao, the other four people in the boat all seemed a little short of breath.

Long Hao smiled and said: "Don't be nervous, with me as a young master, even if Qianlong-1 can't float after diving, I will rescue you safely."

As soon as these words came out, everyone's mood immediately calmed down.

after all.Qianlong-1 was too hasty from its appearance to its launch, and any sailor suddenly had to dive with the ship to the depths of the ocean.There will be some fear in my heart.

The sailor in charge of controlling the diving immediately raised his chest and said: "I am afraid of death and not being a soldier. It is our honor to dive with the young master!... The report shows that the speed of Qianlong-1 has reached zero, and now we are going to dive. It has stopped. The power is switched to the electric motor to start..."

On the wharf, Kunpeng's technicians, the Longlin Navy who stayed behind, Zheng Tingxiang and his gang who sneaked out to wander, and the worried Yuan'er... In short, in the Kunpeng Shipyard, all the people who could be gathered gathered here, if it weren't for the wharf Not wide enough.I'm afraid these people can crush the pier if they squeeze up!

They all watched Qianlong-1 sailing far away with anticipation and nervousness. This test voyage touched everyone's hearts.

Someone asked: "A ship can sink to the bottom of the sea, is it true or not? Can a ship that sinks to the bottom of the sea still be called a ship?"

Someone replied: "You can tell that you didn't listen to the young master carefully. Of course, that guy is not called a ship...that is called a submarine! Submarine, as the name suggests, is naturally a ship that can dive!"

The man asked: "Didn't the submerged ship enter the water? How did it float when it entered the water?"

The man replied: "Fortunately, I participated in the transformation of this Qianlong-1. You can't trouble me with this problem. Floating is very simple. Just drain the excess water in the water tank of the submarine. I will tell you." Tell me, have you ever eaten fish? Have you ever seen a swim bladder..."

There are endless voices in the crowd. Although most of them have been engaged in the shipbuilding industry all their lives, submarines are still too high-end. Foreigners may have heard of them, but for yellow-skinned and black-haired Chinese, it is undoubtedly There is something foreign in the sky.

Novelty, novelty everywhere.

Submarines are also a novelty for Zheng Tingxiang. He has been in the United States for decades. It's the first time seeing the real thing.

Can such a lump of iron really pretend to be a person and sneak into the sea?

Speaking of which, Zheng Tingxiang still had a little opinion of Long Hao before: I am a dignified mechanical engineer in the United States, I abandoned my career in the United States, and followed the advice of my classmates to come to you, but you are good, and I did not follow me from the beginning to the end. Talking about it alone did not give me the attention it deserved.

Children like Zheng Tingxiang studying in the United States have worked hard in foreign countries since they were young, and their self-esteem and spiritual sensitivity are quite high. Therefore, even though he is a "scientific intellectual", he is actually similar to an ancient Chinese counselor and needs the help of the lord. respect and courtesy.

But in the past few days, Zheng Tingxiang's attitude towards Long Hao has changed a lot: he saw Long Hao fighting with the boatmen and working hard all night for the smooth launch of Qianlong-1 for the sea trial. He has no airs , able to mingle with the lower-level workers, and, although he is young, he has a wide range of knowledge. Many problems encountered during the transformation of Qianlong-1, which Huo Lan could not solve, were finally solved by Long Hao's ideas.

Some solutions, such as the idea of ​​the submarine's double-hull structure, originated from Long Hao. After hearing about it, Zheng Tingxiang was also full of whimsy and admiration.

(Note: The double-hull structure, that is, the submarine is composed of an inner shell, and the space in the middle is used as a ballast water tank to control diving and float and improve seaworthiness.)

Zheng Tingxiang's "counselor's coat" was originally thin.Under Long Hao's sincere action, he quickly disappeared.

In the process of transforming Qianlong-1, Long Hao also asked Zheng Tingxiang many questions about mechanical engineering. This kind of quick and eager to learn was also very much to Zheng Tingxiang's appetite.

Zheng Tingxiang is still a scholar after all, and he also knows Long Hao's remarkable innovation achievements in physics.Therefore, after several exchanges, his small opinions on Long Hao disappeared. On the contrary, he felt more and more that only a leader like Long Hao who respects science and practiced himself can lead the Chinese nation out of the quagmire that has been trapped for hundreds of years and revive the past majestic.

In the final analysis, Zheng Tingxiang had already been 'conquered' by Long Hao unconsciously, but... he still had reservations about Long Hao's vigorous research on this 'submarine'.

In Zheng Tingxiang's opinion.Long Hao's establishment of the Kunpeng Shipyard is undoubtedly a correct move, but building a submarine is a bit like creating a robbery for no reason, and it has bypassed his own side who has "scarce robbery".

Shipbuilding, especially the construction of iron-clad ships that can sail in the ocean and win battles at sea, is the current trend, don't you see it.How was the British Empire established?Isn't it supported by its powerful navy?

Germany understands this.Japan understands, America understands too!

Zheng Tingxiang, who is half American, knew this very well, so when Rong Shangqin invited him, he heard that Long Hao owned his own shipyard.He immediately lost his job and took his team all the way to join him.

Rather than saying that the legend of Long Hao's fortune moved him, it is better to say that the bright future of Kunpeng Shipyard attracted him. Zheng Tingxiang understood that the Chinese nation was about to rise.If we want to truly stand at the pinnacle of the forest of nations in the world, we must make up for this lesson in the ocean sooner or later. It is imperative to build big ships, gun boats, and strong boats.

It is with this idea in mind that when Long Hao throws out the "Shorthand Pavilion", Zheng Tingxiang will bury his mind in sorting out, classifying, and explaining these precious shipbuilding materials, because he believes that with these , Kunpeng Shipyard has the hope of catching up with the European powers!

At least... a foothold on the west coast of the United States.

However, under such a favorable situation, Long Hao suddenly "didn't do his job properly". He spent a lot of effort just to subdue a "submarine designer" that the U.S. Navy himself didn't want. The designer was fooling around, calling a large number of boatmen, and in just a few days, knocking and beating, pushed a thing that didn't look like a boat or a boat into the sea!

Zheng Tingxiang sighed and remembered what Long Hao said to him: "Yunyao, don't underestimate the submarine. We want to defeat the European powers and compete for the right to speak at sea. We rely on it! As long as this If there are no major problems in the first trial voyage, I will let Kunpeng Shipyard concentrate on mass producing this submarine!"

Master Long wants to build submarines on a large scale?

Zheng Tingxiang was very conflicted, he felt as if he was watching his ex-girlfriend go astray in order to live a better life, but he was powerless... He knew that Long Hao was walking on a 'wrong' path, but he couldn't do anything about it... dissuade.

Thinking of this, Zheng Tingxiang's eyes returned to the sea surface, and returned to the gradually shrinking Qianlong-1.

Perhaps, this test voyage must fail... It would be better.

A thought that he couldn't even imagine suddenly jumped out of Zheng Tingxiang's heart.

"Look, look, look, it's sinking, it's sinking!"

Zheng Tingxiang's complicated thoughts were interrupted by a loud cry. He quickly looked up and found that the people around him raised their hands and shouted like crazy, and Qianlong-1 at the end of the sea level was impressively below. latent!At this moment, the hull of the ship has completely disappeared, only the shadow of the hatch cover can be seen vaguely.

"What's called sinking? That's called diving. It's when a submarine dives into the sea on its own initiative... A sinking ship is called sinking. It's uneducated!"

"You know a lot, so tell me, after diving, can that submarine still float?"

"Of course it can float, otherwise, isn't it courting death if you take the initiative to dive?"

"Then why didn't you see it float up now? It's been a few minutes, and you can't suffocate to death in the water!"

"Hey, you don't admit that you are uneducated! After the submarine dives, it can continue to sail. How can it float up in place? Just wait, maybe it will float in front of you with a crash, scaring you One jump!"

"So that's how it is... Hmph, don't think that you'll have to be seduced if you pass the third-level boatman exam. Besides, I'm uneducated, and I'll beat you up!"

……

Inside the cabin of Qianlong-1 boat.

"Report, the dive depth is 20 meters... 30 meters... 35 meters..."

"Count. It's almost there? Thirty-five meters is fine."

Listening to the sailor's report on the parameters, Huo Lan said to Long Hao anxiously.

For current submarines, a dive of 20 meters is quite remarkable, but now Long Hao has nearly doubled the dive depth of Qianlong-1. How can this not make Huo Lan feel like a deer?

The pressure of sea water is no joke, if the hull of the submarine breaks.The sea is coming in and we'll all be crushed into meatloaf!

"Don't worry, I think 50 meters is probably the limit... Uh, hehe, John, your face is pale, okay, stop diving, what is the current depth?"

Long Hao teased Huo Lan.Finally, the order to stop diving was issued.

"Report, the current depth is 36.5 meters!"

"Very good, start to speed up and conduct underwater navigation test!"

It stands to reason that in this era, submarines do not need to dive so deep. After all, if they want to launch torpedoes to attack the opponent, the depth is about 10 meters.Just make sure you don't bump into the opponent's warship... However, the diving depth of the submarine is always an important indicator.When the power of the submarine was revealed and the enemy began to vigorously blow out the shipbuilding technology, it was far from enough to dive 10 meters or 20 meters!And, on the other hand, the deeper the submarine dives.The greater the protection for oneself, that's why Long Hao asked Huo Lan to take the diving depth of the submarine into consideration in the future work of improving the submarine.

"Yes, the power of Qianlong-1 has been switched to the electric motor... The electric motor is running well at present. The speed has been increased to 1.1 knots!"

Qianlong-1 is about 36 meters underwater, and the seawater pressure it receives is almost twice that at 20 meters. Huo Lan couldn't help but asked worriedly: "Is it going to dive too deep? If the motor can't drive, If it stops, it will be terrible! My lord, it’s just an experiment, so there’s no need to be so demanding? In the world’s navies, I can assure you that as long as the submarine dives to 20 meters, it will never be discovered!”

The depth is not deep, and the high-strength steel synthesized by directly extracting free metal elements from the continental shelf, this seawater pressure is nothing at all!Long Hao squinted his eyes and thought: But... what John said is somewhat reasonable. Now that 20 meters can be done, why do we have to dive to 36 meters before giving up?Floating a little bit, the salinity, temperature, and density of seawater will change, which is also good for increasing the speed of Qianlong-1.

Thinking of this, Long Hao followed suit with a smile, and said with a smile: "That's it, okay, listen to John and start to float, and by the way, do the experiment of floating a moving submarine! Pay attention, listen to my orders, Qianlong -1, start to float, the target is 20 meters below the sea surface!"

"Yes, Qianlong-1 has started to float, and the current depth is 36.2 meters... 35 meters... 25 meters..."

"The motor is running well, the speed of Qianlong-1 is increasing, 2.3 knots... 4 knots... 8 knots..."

Long Hao and Huo Lan stood aside, watching the three sailors busy as bystanders. Of course, most of their busy work was to observe the values ​​of various dashboards and observe whether the various components of the submarine were operating normally!

Unknowingly, Qianlong-1 has risen to a depth of 20 meters in the seaman's constant counting, and its speed has also increased to 12 knots.

The underwater speed is 12 knots, which is a very terrifying value. Huo Lan walked to the closed power compartment at the rear of the ship with some disbelief, and was extremely surprised: "My lord, where did you buy the electric motor? Its power It's really... really incredible that it can surpass the internal combustion engine!"

12 knots underwater, because of seawater resistance, fish, temperature, density, salinity and other parameters, the power required is not the same as that of 12 knots on the water surface!In today's era when electric motors are just emerging, it is definitely a great invention and a great leap to have an electric motor with a power greater than that of an internal combustion engine!

Where did you buy it?

Is this what Master Ben did with his own money?Only this one, no semicolon!

Long Hao cried out in his heart and smiled: "Where did you buy it? This motor is the most common one purchased in the United States! But, John, do you remember? I discussed it with Zheng Tingxiang and Zheng Zheng for two days, and I got the answer. It has benefited a lot, so I modified it on my own initiative, and now it seems that this improved motor...is working very well!"

While talking, the stealth speed of Qianlong-1 is still increasing, and at this moment, it has exceeded the 15 knot mark!

Discussed for two days, modified a bit, the speed reached 15 knots?

John Holland's stomach twitched for a while, and he wanted to spray Long Hao's face with blood: Are you too ridiculous?This change, which can be called the motor mileage brand, was created by you just like this?No, I can't be fooled again, Earl, I, John Holland, will never accept this kind of anti-scientific and unreasonable explanation!

Seeing the disbelief on Huo Lan's face, Long Hao smiled wryly, spread his hands and said, "Why, don't you believe me?"

"I don't believe it! Unless you open the power cabin and let me have a look at the electric motor!" Holland said decisively, with a serious expression, Earl, if you don't make it clear today, don't expect me to help you continue to develop submarines in the future.

"It's true!"

Long Hao stood in front of the closed power cabin, and his tone was flat and helpless: "John, don't you believe that there are geniuses who have epiphany in the world? Unfortunately, I am a genius among geniuses, the best of the best, Two days is enough for me to improve a motor... Have you forgotten that I was the first to create the "quantum mechanics theory"? In physics, it is difficult to improve a motor. I did not do it Not yet?" (To be continued...)
