Chapter 885 Amazing speed!

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.

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

The earliest history of human beings entering underwater through foreign objects can be traced back to 2000 years ago. Yan Alexander I sat in an airtight container and sank to the bottom of the sea for a while, and then floated up again.According to legend, the earliest submarine was made in England in 1622 by the Dutch inventor Dreybel according to Da Vinci's design.The submarine, which is made of wood and covered with oil skin and sealed, was built from Westminster to Greenwich at a depth of four meters underwater.

And people's earliest understanding of submarines, in fact, comes from one of Jules Verne's trilogy "Twenty Thousand Leagues Under the Sea". The Nautilus in it is the first time many people understand the application of submarines.In fact, many designs on the Nautilus were used for reference by later submarine designers.

At present, the fastest submarine recorded in the world is a nuclear submarine built by the former Soviet Union during the Cold War—the Type 661 nuclear submarine called P-class by NATO. Its underwater endurance speed exceeds 44 knots, which is as fast as the torpedo at that time Can't catch up!Of course, the combat performance of this type of submarine will not be very good if the speed and dive depth are fulfilled.

And what is the speed of the underwater high-speed thruster tested today?
Watching the underwater propeller, painted white for conspicuousness, gradually accelerate, the data in the lower right corner of the screen is also showing its speed value, from 1 knot, to 2 knots, to 4 knots, to 7, 10-15, Still accelerating!
The specially cleared channel is very clean, without obstacles, with clear sightlines and good water quality, making it an ideal environment for testing.

"It's thirty knots!" Someone exclaimed behind Lin Dong, "During the initial test earlier, thirty knots was the peak... Could it continue to accelerate?"

Apparently, no one answered, but the white propellers on the big screen that were swimming underwater like a swordfish gave the best answer!

"The speed is still increasing! Forty knots! Damn it!"

Someone couldn't help but swear, although the underwater submarine's navigation, from a tactical point of view, the most valuable should be silence and small reflection waves to sonar, because only in this way can we ensure that the submarine can stay underwater as much as possible. Undetected, or try to sneak as close as possible to the enemy ship to launch an attack-if the enemy discovers it at the beginning, then the submarine that was hanged will be your own submarine!

However, speed is still key!
Think about it, even if I was really discovered, I turned around after firing the weapon and ran away. If the large surface ship can't catch up, it is very possible to get rid of it!

"Fifty knots!" This time, even Lai Tongguang, who had always been relatively calm, couldn't help exclaiming, "Isn't this speed...too exaggerated?"

The speed of sea navigation is expressed in "knots". Many people should know that a knot is one nautical mile per hour, and converted into kilometers is 1.852 kilometers per hour.The speed of 90 knots is almost 90 kilometers, which is underwater.Everyone has swum before, and the speed underwater is much greater than the resistance in the air. If you can reach more than [-] kilometers underwater, that is the speed of a super sports car!
However, it continues to accelerate!
Everyone present could see that although the acceleration of the white underwater thruster is not as strong as before, that is, the acceleration is not as high as before, but it doesn't feel like it is coming to an end, but there is still plenty of power to spare. In other words, at least it can accelerate for a while!

At the current speed, most torpedoes in the world can no longer catch up!
And the speed is still accelerating!

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

He suddenly asked: "Can I get in touch with the operator in the thruster now?"

"Yes!" Lai Tongguang sweated for a while. He waited for others to marvel at the speed of the thruster. He didn't even think about contacting the people inside, and didn't ask about the situation inside. It was really remiss!

"Then let's get in touch and ask 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 hastily picked up the microphone—the frequency had been adjusted long ago. He turned on the switch, coughed a little, and said, "Swordfish Swordfish, I'm a fish nest, and I'm reporting your situation now!"

"The current situation is good." It can be heard that even the operator is very excited at the moment, "The motor is running normally, and the power has not reached the maximum load. It is estimated that the speed can be increased by about one-third, and the maximum speed is expected to reach 100. All indicators are normal, but the seat in the operating cabin is not stable enough, and needs to be improved after returning... The glass and steel windows on all sides are in normal condition, and the water pressure is normal. The current diving depth is 30 meters, and there is no problem at all... "

Although the operator's voice was tense, it was very steady, and it could be heard that the situation in the operation cabin should be good.

"Swordfish swordfish, when the speed reaches or is close to 2 knots, if there is no problem, then test the depth of the dive. The test location is in area [-]..." Lai Tongguang has returned to normal, and started to issue according to the established test plan instruction.

"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 the maximum - the largest version was taken away by the military. Naturally, we cannot compare with the military. This The propeller is a simplified version, but it is already very unexpected!"

Lin Dong nodded, his eyes still on the big screen.It can be seen that the acceleration of the propeller 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 drag racing on land!

Soon, the speed of the propeller reached [-] knots. At this time, it was already less than one kilometer away from the farthest area of ​​the test!
The thruster obviously began to slow down. It can be seen from the screen that all the indicators of the thruster are normal, and there are no values ​​that are unstable or reach or exceed the warning line.

At least for now, the speed is completely passed!
