Open an aircraft carrier to fight against Japan

After Lin Yuan finished speaking, he picked up the sounding pole from the boat, put it into the water, then pointed to it and said to Fade Chen: "When I say stop, you can tell me the reading of the waves passing by."

Chen Fei asked: "What is this going to do?"

Lin Yuan put down his watch, pen and paper, and said, "To explain this, we need to start with the water pressure fuze. This time I plan to use the water pressure fuze mine to deal with the British transport ships. You know the water pressure. You just When you are underwater, the water will have a pressure effect on you, this is water pressure."

"However, when you are in the water, the speed of movement is very slow. The pressure of the water on you is static pressure. When the ship travels in the water, the ship has speed and will push the water to move, so the water pressure will change. This change is The conditions for the action of the water pressure fuze, but the water surface cannot be strictly static, there will be waves, and these waves will also cause changes in the water pressure, so we need to know the characteristics of the wave pressure."

"When we understand the pressure characteristics of waves, we can set the operating conditions of the water pressure fuze, do you know? The dynamic pressure caused by the ship is not linear, but varies in size, and the distribution also has certain rules. We can According to the difference between this pressure and the wave pressure, set the conditions under which the mine should detonate, and the height of the wave is the key factor in determining the water pressure."

Fade Chen nodded, and the two of them measured more than a dozen sets of data in this way. During the data measurement, Lin Yuan said to Fade Chen, "Did you know that hydraulic fuze mines are the most difficult to eliminate among non-trigger mines. Currently, for non-trigger mines, For sea mines, the most effective method is to artificially create a ship signal, making the sea mine think that a ship is coming, and it will detonate by itself."

"However, it is extremely difficult to simulate the water pressure signal. If you want to simulate it, you need millions of watts of power, so it is basically impossible to artificially simulate the water pressure signal."

The two of them worked for a while before returning. After returning, Lin Yuan sent two more mines. Jin Siqin, the mine operator on the Beijing ship, came to Shanghai Port on a tugboat.

Lin Yuan started the task deployment immediately after everything was ready. First, Lin Yuan set up the headquarters on the tugboat, and then held a meeting. At the meeting, Lin Yuan said: "Comrades, our operation this time can be counted. In the last paramilitary operation, our goal was to seize the metal ores in the two British cargo ships. These ores are very important for national defense. I believe everyone has already understood the importance, so I won’t emphasize it.”

"Let me talk about the distribution of tasks. We are divided into three groups. The first is the mine-laying team. Comrade Jin Siqin and I are in charge. The enemy ship will leave the port at [-]:[-] tomorrow morning, and we will lay mines at [-]:[-] am; The second is the diver team, which is in charge of Comrade Chen Fei. When the explosion occurs and the enemy ship sinks, you immediately go into the water and hang the tugboat cable on the hook of the container; the third is the tugboat team, which is in charge of the comrades on the tugboat.”

"When the diver sends out the signal of the hook line lock, you don't care about anything, and leave the port at full speed, because the British army has three warships here, including a Majestic-class battleship, so the combat capability should not be underestimated. Once you and When they meet, don’t resist, if they ask to board the ship for inspection, you can cooperate, even if they want to detain you, don’t be afraid, I will try my best to rescue you.”

Lin Yuan looked around and said, "If there is no problem, let's adjourn the meeting."

Everyone dispersed and prepared separately. At two o'clock in the morning, Lin Yuan and Jin Siqin came to the waterway with two mines. These two mines are bottom-sinking mines. The spiders and mines that sink the bottom generally have a relatively large charge, and the charge of these two mines weighs [-] kilograms.

There are three types of sea mines, bottom mines, anchor mines, and floating mines. If this kind of charge is placed on the anchor mines or floating mines, it can already make the sea mines rank among the large mines, but in the bottom mines, such The amount of charge can only make it the little brother of the family. The charge amount of real large-scale bottom mines is more than [-] kilograms, and some can even reach one ton.

The weight of this mine is as high as more than 500 kilograms, which is definitely too heavy for people to carry. Therefore, when the Beijing ship set off, a mine delivery device was installed on the small boat to specifically put the mine into the water.

Lin Yuan felt that the time was ripe, so he said: "We can lay mines, let's start now, I have scouted the ship type information of the transport ship, and according to the relevant formula, I have calculated the movement speed of this type of transport ship in the water. The water pressure that will be generated." Lin Yuan said and handed a data sheet to Jin Siqin, which also contained data on the environmental water pressure.

Jin Siqin looked at the data, opened the control box at the tail of the mine, gently rotated the cam inside, worked out the detonation conditions, and said: "Okay, this time the mine can only blow up the transport ship." Jin Siqin said After finishing, remove the cover of the mine, exposing the strip-shaped body of the mine.

Laying mines on a ship has very little requirement for the shape of the mines. Unlike air-dropped mines, a hemispherical head is usually glued to it. The head is made of wood and will be shattered when it enters the water, which can protect the mines.Jin Siqin pressed the operation button, and the mine slowly entered the water. If the mine fell uncontrollably on the bottom of the water, it would have a great impact force. Therefore, there is a hinge in the delivery system to pull the mine, so that the mine slowly touches the water. underwater.

Jin Siqin felt that the mine had sunk to the bottom of the water, so he let go of the hinge, and then released the next one. After the mine was dropped, Lin Yuan did not let the boat return to the tugboat, because the tugboat was likely to be targeted by British warships. , if the British are on board, how to explain the mine delivery system?

So Lin Yuan sailed into a relatively remote harbor with a small boat, then rented a civilian boat, and came to the mine-dropped waters. As the sky gradually dawned, he used the boat to pass through the mine waters from time to time. Speed ​​is related to the underwater shape of the ship, and these ships are too small to detonate mines.

Lin Yuan looked at his watch. At eight o'clock, a message came from Lin Yuan's communicator. It was sent by the comrades monitoring the transport ships at the port: Two British transport ships have left the port and entered the waterway to lay mines. location.

Lin Yuan raised the binoculars in his hand and looked in the direction of the ship, only to see a familiar figure appearing in the channel. It was the Blackbird that he saw that day. The Blackbird knew nothing about the underwater danger. Slowly drove into the range of action of the mine.

The water pressure sensor on the mine instantly senses the change in water pressure. Its sensor sends the change signal to the signal amplifier, and the amplifier sends the amplified signal to the processor. The processor ignores the signal at the beginning, because the signal sent There were too many signals coming in, and soon the follow-up signals were also sent, and the processor became excited, because this series of signals was so similar to his pre-set detonation signal!

The processor immediately sent out a detonation signal, a current was amplified layer by layer, and finally entered the detonator, and [-] kg of high-energy explosives were instantly detonated!
