The high-definition high-speed camera clearly captured the figure of the underwater high-speed thruster, and Lin Dong looked at the screen without blinking. Pen & Fun & Pavilion www.biquge.info

Although I have a video of the complete thruster design and manufacturing technology and practical application in my mind, this is the first time that it really looks like it.

The earliest history of human beings entering the water through foreign objects can be traced back to 2,000 years ago, when Yan Lishan sat in a closed container and sank to the bottom of the sea for a while, and then floated up again. The earliest submarine, according to legend, was founded in 1622 by the Dutch inventor Dreber according to the Da? Vinci's designs are made in England. The submarine, made of wood and sealed with an oily skin, was built from Westminster to Greenwich at a depth of four meters.

And people's earliest understanding of submarines is actually from Jules? One of Verne's trilogy, "20,000 Leagues Under the Sea", in which the Nautilus is the first understanding of the application of submarines for many people. In fact, many of the designs on the Nautilus were borrowed and used by later submarine designers.

At present, the fastest submarine recorded in the world is the nuclear submarine built by the former Soviet Union during the Cold War - the Type 661 nuclear submarine, which is called the P-class by NATO, and its underwater endurance speed is more than 44 knots, and the speed is so fast that even the torpedoes at that time could not catch up! Of course, with the speed and depth of the dive, the combat performance of such submarines is not very good.

And how fast can the underwater high-speed thruster tested today reach?

Looking at the underwater thruster that was deliberately painted white for conspicuousness, it gradually accelerated, and the data in the lower right corner of the screen also showed the value of its speed, from 1 knot, to 2 knots, to 4 knots, to 7, 10-15, and still accelerating!

The specially cleared channel is very clean, free of obstacles, clear sight, good water quality, and is an ideal environment for testing.

"It's thirty knots!" Someone exclaimed behind Lin Dong, "During the initial test in the front, the thirty knots were the peak...... Can it continue to accelerate? ”

Obviously, no one answered, but the white swordfish-like thrusters on the big screen gave the best answer!

"The speed is still improving! It's forty knots! No way! ”

Someone couldn't help but burst out foul mouth, although the navigation of underwater submarines, from a tactical point of view, the most valuable should be silence and small reflection waves from sonar, because only in this way can we ensure that the submarine is as undetected as possible underwater, or sneak to the closest place to the enemy ship to launch an attack - if it is discovered by the enemy from the beginning, it is your own submarine that is being beaten!

However, speed is still key!

Think about it, even if it is really discovered, I turn around and run after firing the weapon, and in the case of large surface ships that cannot catch up, it is very possible to get rid of it!

"It's fifty knots!" This time, even Lai Tongguang, who has always been relatively calm, couldn't help but exclaim, "This speed...... That's an exaggeration, right? ”

Many people should know that a knot is what one nautical mile per hour looks like, which is converted into kilometers and is 1.852 kilometers per hour. At a speed of fifty knots, almost more than ninety kilometers, this is underwater. Everyone has swam and swimmed, and the speed underwater is much greater than the resistance in the air, and it can reach more than 90 kilometers underwater, which is the speed of a supercar!

And yet, it continues to accelerate!

Everyone present can see that although the acceleration of the white underwater thruster is not as strong as just now, that is, the acceleration is not as big as just now, it does not look like it is almost at the end, but it still has a lot of spare power, that is, at least it can accelerate for a while!

At this rate, most of the torpedoes in the world will not be able to catch up!

And it's getting faster!

Lin Dong's gaze had already fallen on the microphone next to the operator under the screen.

He suddenly asked, "Can you get in touch with the propeller operator now?" ”

"Yes!" Lai Tongguang sweated for a while, and he and the others patronized and marveled at the speed of this thruster, and he didn't think to contact the people inside, and he didn't ask about the situation inside, it was really a dereliction of duty!

"Then let's get in touch, and asked if the situation inside is stable." Lin Dong said: "We can't just look at the speed outside, but also look at the facilities and equipment inside. ”

Lai Tongguang hurriedly picked up the microphone - the frequency had already been adjusted, he turned on the switch, coughed slightly, and then said: "Swordfish and swordfish, I am a fish nest, now report your situation!" ”

"The current situation is good," can be heard, even the operator, who is very excited at the moment, "the motor is running normally, the power has not reached the maximum load, the speed is expected to be increased by about a third, and the maximum speed is expected to reach 100 knots!" All indicators are normal, but the seats in the operating compartment are not stable enough, and they need to be improved after going back...... The FRP windows on all sides are in normal condition, the water pressure is normal, and the current diving depth is 30 meters, without the slightest problem......"

The operator's voice was tense, but steady enough to be heard, and the situation in the cabin should be good.

"Swordfish Swordfish, when the speed reaches or approaches one hundred knots, if there is no problem, then test the depth of the dive, and the test site is in Area 2......" Lai Tongguang has returned to normal and began to give instructions according to the established test plan.

"Swordfish received, swordfish received!"

Putting down the microphone, Lai Tongguang explained: "Because it is a civilian version, neither the speed nor the depth of the dive is designed to be the maximum - the largest version was taken away by the military." Naturally, we can't compare with the military, this thruster is a simplified version, but it's already very unexpected! ”

Lin Dong nodded, his eyes still falling on the big screen. It can be seen that the acceleration of the thruster has begun to slow down now, but the process of propulsion is still very stable, and the speed on the screen has reached an astonishing eighty knots!

This speed is much faster than racing on land!

Soon, the speed of the thrusters reached a hundred knots, and by this time, it was already less than a kilometer away from the farthest area of the test!

The thruster obviously began to slow down, and it can be seen from the screen that all the indicators of the thruster are normal, and there is no instability or a value that reaches or exceeds the warning line.

At least for now, the speed is completely passed! (To be continued.) )
