A submarine submersible is, to put it bluntly, an unmanned underwater vehicle that is unmanned and can be remotely controlled.
The technology of this thing is not complicated. As early as the 1950s, the first unmanned submarine was born. In the 1990s, China also had its own unmanned submarine under the promotion of Project 863.
technology.
The submarine submersible of the 749 Bureau is not an advanced thing compared to those unmanned submarines. Whether it is the manufacturing process, radar and ultrasonic devices, power equipment, etc., other countries can manufacture it. Even so, this
Taiwan's submarine submersible machine is still an out-and-out black technology equipment. And this black technology is the deep-sea radio transmission system on the submersible machine.
Nowadays, unmanned undersea vehicles in various countries around the world, even the most technologically advanced United States, can generally only use optical cables for remote control in the control mode of unmanned undersea vehicles. There are connected to the buttocks of their undersea vehicles.
An optical cable several kilometers long, through which people on the ship control and observe the unmanned underwater vehicle.
Compared with them, the underwater submersible aircraft has completely thrown away the small fiber optic cable tail, but uses radio for remote operation.
Although it sounds nothing special, if you know the degree of attenuation of electromagnetic waves in water, you will be amazed by this technology.
Just like sugar will be dissolved by water when put into water, electromagnetic waves will be absorbed by water when they enter water. General underwater radio transmission can only reach a distance of several hundred meters, and this is still using large
In the case of a power radio, however, the radio equipment on the submarine submersible can transmit hundreds of kilometers in the water. Both the transmission speed and quality are almost the same as those in the air.
The secret is that this submarine submersible uses the latest technology developed by the 749 Bureau Research Office through research on contained objects. I don’t know the specific principle. I just accidentally heard it highlighted.
Speaking of which, it seems that something is used to change the wavelength of radio so that it can penetrate the obstruction of sea water. The inventor of this technology is the thin woman lying on the back of the submersible machine in front of him, Dr. Mo Xi.
Because it was considered that traditional unmanned undersea vehicles would have the risk of their cables being broken by monsters in the sea when encountering giant creatures on the seabed, the bureau specially brought this undersea submersible. And because
No one except Mo Xi can figure out the radio transmission system in this submarine submersible so far, so they let her board the Snow Dragon.
Seeing that Mo Xi was already playing with the submarine submersible, I whispered next to Gao Liang: "Chief Gao, are you going to ask how the situation is?"
Gao Liang frowned, stared at the figure on the back of the machine with squinted eyes, and finally said to me: "Forget it, even if we ask, do you think she will answer? Let's wait until she has finished it."
I saw that Mo Xi had disassembled the submersible machine. I originally thought that she might check it for a long time, but to our surprise, after only two or three minutes, Mo Xi stood up from the back of the machine.
I started to pack up the data cables and put the computer back into the bag.
Upon seeing this, the two of us immediately walked over. Gao Liang asked Mo Xi, who was still packing his things, "Dr. Mo, how is the situation with the submersible?"
Mo Xi, who jumped off the diving machine, was still expressionless, and said to us with a poker face: "The radio transmission system is fine, but I don't know about the other equipment. We need to conduct an underwater trial."
"You mean you have to put that thing in the water and swim around?"
Mo Xi nodded: "Yeah."
Gao Liang turned around, looked at Wang Jingzhong on the side, and asked him: "Captain Wang, what do you think? Let the Snow Dragon stop temporarily. We must check the condition of the submersible. If there is a problem with it, we will
I’m afraid this mission won’t be able to continue.”
Because of the order given to him by his superiors, Wang Jingzhong naturally did not dare to have any objections to Gao Liang's proposal. He quickly issued the order to stop the ship, and then asked people to start preparing for the sea trial of the submarine submersible.
The preparation work went smoothly. Almost half an hour later, under our watch, the submarine submersible was sent into the sea by a crane.
Watching it gradually disappearing on the sea level, Gao Liang patted Wang Jingzhong on the shoulder and said to him: "Captain Wang, let's go and see the latest technology of the navy."
In order to deceive others, the submarine submersible has been promoted as the navy's latest experimental underwater drone in front of the crew of the Snow Dragon. As a member of the navy, Wang Jingzhong has naturally been very coveted for this thing. When he is fine, he often
I want to find out about the diving machine from us.
So when he heard Gao Liang's invitation, his eyes suddenly lit up, and he said happily but hesitantly: "Is this...appropriate?"
"No problem, let's go." Gao Liang said as he led us to the control room of the submersible.
The control room of the submarine submersible is right next door to Mo Xi's room. It was also temporarily converted from a guest room. It houses the radio receiver and control system dedicated to the submersible.
When we opened the door, Mo Xi was already inside. She was sitting in front of a screen, fiddling with a device like a flight joystick while watching the changes on the screen.
"Captain Wang, this is the control device of the submarine submersible." Gao Liang pointed to the joystick in Mo Xi's hand and introduced, "And the content played on this screen is the underwater scene captured by the submarine submersible."
"In addition to the use of radio control, the underwater cameras of submarine submersibles are also very different from those ordinary underwater cameras." Gao Liang explained to Wang Jingzhong, "Ordinary underwater cameras can only shoot a few tens of meters.
The underwater camera equipped with this submersible machine uses an ultrasonic photoelectric camera developed by Dr. Mo Xi, which can record images from a few meters to ten kilometers away on the dark seabed.
Object image."
"It's amazing. It's amazing." Wang Jingzhong sighed on the side, "I have also been exposed to the navy's previous unmanned underwater vehicles. They were too restrictive because they dragged a tail. They could only be used in the field of deep-sea exploration.
Unlike this thing, it only needs a radio to control it from a long distance. This submersible machine is convenient and safe. If it can be deployed in large numbers, then those submariners will probably be laid off in the future."
Wang Jingzhong's words made Gao Liang and I couldn't help but smile at each other. We also equipped a large number of equipment? I heard that just the one we brought this time was made with great difficulty after the bureau exhausted its resources.
The only one is finished.
Although the Arctic Ocean is the coldest ocean in the world, the underwater world here is still very lively. From time to time on the screen of the snorkeling machine, we can see some dense undersea mountains, deep trenches, and a large number of
School of fish in the sea.
Wang Jingzhong walked around the room with his hands cut behind his back, glancing at the screen from time to time. Not only him, but Gao Liang and I were also the same, because we were all fascinated by the mysterious underwater world captured on the submersible machine.
However, such a beautiful moment ended quickly. After almost two or three minutes, we found from the picture on the submersible that the submersible had begun to move away from the bottom of the sea and slowly rose towards the sea surface.
Seeing this, Gao Liang asked: "Dr. Mo, how is the situation of the submersible? Is there any problem?"
Mo Xi paid attention to the fluorescent screen and replied: "There is nothing abnormal. I am ready to let it return."
"So fast? Don't you need to check more?" I said a little surprised. In fact, I felt it was a pity and wanted to see more of the underwater scene just now.
Mo Xi looked back at me and said, "Do you think the swimming machine is a toy?"
"How could it be?" Gao Liang stood in front of us and smiled at Mo Xisha: "We told you before we came here that we will obey your orders regarding the diving machine. As long as we can ensure that this thing will go smoothly by then
Just use it. Since Dr. Mo said there is no problem, let the submersible machine return."
After saying that, Gao Liang whispered to me: "How many times have I told you not to provoke this person? Without her, our mission would not be able to continue at all."
After he finished speaking to me, Gao Liang winked at Wang Jingzhong and asked him to go to the deck and ask people to prepare for the recovery of the submersible.
Wang Jingzhong looked like me. He seemed to feel a little regretful that he could no longer watch the underwater images sent back by the submersible machine, and he still had some unfinished thoughts. Therefore, he reluctantly left the room, turning back three times before leaving the room.
However, Wang Jingzhong only left for a few seconds before suddenly returning.
Gao Liang asked him: "Captain Wang, why are you back again?"
"Sorry, I just thought of something."
Wang Jingzhong walked to Mo Xi, lowered his head and asked: "Dr. Mo, when the submersible machine returns, can you let it take a look at the bottom of the Snow Dragon? After the Snow Dragon just collided with the ice, there seems to be something on the bottom deck of the ship.
Several places were severely damaged, and although the damage control crews are already inspecting it, they still don’t know if there are any cracks.”
He pointed to the screen of the submersible machine and said: "So I think it would be great if we could use the submersible machine to observe it. Observing the hull directly from the outside should save us a lot of time in repairs."
"May I?"
After listening to Wang Jingzhong's explanation, Gao Liang turned around and asked.
…
After thinking for a moment, Mo Xi nodded.
Therefore, Gao Liang immediately waved to Wang Jingzhong and said to him: "Then come over quickly and tell Dr. Mo where you want to check?"
Under Wang Jingzhong's instructions, Mo Xi quickly controlled the submersible machine and swam to the bottom of the Snow Dragon. Under the filming of the underwater camera, the scene at the bottom of the Snow Dragon clearly appeared on the screen, allowing Wang Jingzhong to see it clearly.
However, at this moment, Wang Jingzhong suddenly screamed: "What is this situation?"
When he yelled like this, my scalp also went numb. Because I saw that in the picture taken by the submersible machine, there was a huge handprint that suddenly appeared on the bottom steel plate of the Snow Dragon!
What's going on? Didn't the Snow Dragon hit an ice floe just now? Why did I see a person's handprint at the location of the impact? And this handprint looked even bigger than the entire submarine submersible machine!
