After listening to the radio.
Second Lieutenant Wang Haiyang said: "Let's make preparations and don't get seasick at night."
Li Zheng asked: "Our physical fitness is so good, isn't it? This is not the first time we have gone to sea."
Wang Haiyang said: "That's not true. Seasickness is something that no matter how old a veteran is, it will happen to all veterans. It takes an adaptation period to sail. If you don't get dizzy, you are great. If you get dizzy, there is no shame in it."
Li Zheng was very curious about Wang Haiyang's caution.
I have been in Lute for so many years, and I have been studying in Haite for almost half a year. I have also gone out to sea with the team. Although they were all offshore, I have never experienced seasickness.
As an elite special forces soldier, Li Zheng did not believe that he would get seasick.
seasick?
What the hell!
How can it be!
Not to mention anything else, Lu Te also has anti-vertigo training.
It's all made through hard work. No matter what you do, you won't get seasick, right?
But in fact nature quickly taught Li Zheng a lesson.
Seasickness is a very strange thing. It does not mean that you will not get sick if you undergo high-intensity training, just like altitude sickness does not mean that you will not get altitude sickness if you are in good health.
Seasickness is more or less evil. Many veteran seafarers will get seasick. If you don't feel sick today, it doesn't mean you won't feel sick tomorrow. If you don't feel sick now, it doesn't mean you won't feel sick in the future. It's just that if your body is strong enough, you will recover quickly after you faint.
The difference is just that.
At around 8 p.m., the ship entered a tropical storm zone.
Since they are still within the waters of their own country, the special operations team members do not need to go outside the cabin to perform guard duty.
At this time, other navy sailors on the ship were very busy, and the most bored ones were the sniper team.
When the boat started to rock, Fatty Wei was still blowing water and continued to brag about his fishing experience.
Occasionally, various messages came over the radio.
Everyone learned through the radio that the wind and waves in the current sea area had reached Level 7. The captain sent someone over to ask everyone if they could adapt.
After all, they are special forces. Who dares to say that they are not suitable?
They all said there was no problem, nothing wrong, nothing happened at all, it was a big deal!
The officer who came to inquire about the situation came with a smile and walked away with a smile. He was walking smoothly on the rocking ship, which Li Zheng had to admire.
This is experience.
In special operations, their individual soldiers are not as good as yours, but when it comes to adaptability on the ship, they are really better than you. You have to admit this.
Li Zheng curiously asked Wang Haiyang whether this kind of wind and waves was considered big during a long voyage.
Wang Haiyang said lightly: "It's just so-so, no big deal!"
As the saying goes, there is no wind without waves. In the wind level comparison table, a force 10 wind can produce waves of about 9 meters, while a force 11 wind can produce huge waves of 11 meters. The maximum wind wave of a typhoon of force 12 is 14 meters, which means the sea state of a 10-meter wave Slightly higher than level 10 wind.
Warships are surface ships that operate in all sea areas and in all environments. Therefore, their ability to withstand wind and waves is more demanding than ordinary merchant ships. Wind and waves are a major test for the strength, sinking resistance, and stability of the ship's hull.
Our country divides the wind and wave resistance capabilities of ships into five levels. Level one can withstand winds of level 12, while level two can withstand winds of level 11.
In addition to logistics supply ships, front-line combat ships are usually classified by displacement, with small frigates ranging from 1,000 to 2,500 being level 2.
In other words, even small-tonnage ships such as the Type 056 frigate can withstand winds of level 11 and waves of about 9 meters.
Ships above 2,500 tons are the highest level, which means that destroyers and frigates above the 054A frigate have the ability to sail in level 12 typhoons and waves of more than 11 meters.
The displacement of the 052 series destroyers is generally more than 5,000 tons, and the displacement of the 055 large-scale destroyers is more than 10,000 tons. It is naturally no problem to cope with wind and waves of more than 10 meters.
If it is an aircraft carrier, the large ship can sail safely in 14 super typhoons and huge waves of more than 15 meters without any problems.
So how do warships ensure that they can sail in strong winds and waves without being blown over or overturned by waves? There are three main reasons:
First, the appearance design. The reason why a ship does not sink is because the buoyancy is greater than gravity, so it is necessary to improve its ability to resist wind and waves. If the ship takes in too much water during navigation, its own gravity will be too high, and the waterline will eventually become deeper, creating the risk of capsizing or even sinking. At present, mainstream warships adopt a fully enclosed design, and the deck adopts an arched design. There are also multiple drainage holes designed around the hull, which can minimize the intrusion of water in wind and waves.
Next is the pressurized water tank. Everyone knows that the tumbler will not fall over no matter which direction you apply force. The core of the tumbler is its low center of gravity. Therefore, in order to ensure that it can maintain its center of gravity in huge waves and avoid capsizing, the warship is also designed with its center of gravity tilted toward the bottom. Position, this is the legendary ballast water tank. The ballast water tank can not only reduce the center of gravity of the ship, but also greatly increase the correction force of the warship when the attitude is deflected. Therefore, the warship can still be tilted even when the hull tilt reaches 45 degrees. Keeping it from capsizing relies on the function of ballast water tanks.
Finally, there is the stabilizer. To deal with frontal attacking waves, warships can use their V-shaped bows to cut through the waves, but for horizontal wave crests, it poses a huge safety hazard to the stability of the warship. Sometimes the deflection of the ballast tank is no longer strong enough to correct it. The overall posture of the warship requires the use of stabilizers at this time. The stabilizer is a bionic product inspired by the pelvic fins of fish. It is generally installed on the bilges on both sides of the ship (the joint between the bottom and the side of the ship). When waves hit the stabilizer, it can produce a The deflection moment in the opposite direction of the hull movement reduces the rolling of the hull.
Therefore, for 054A, a level 7 wave is really, as Wang Haiyang said, “not a big deal.”
As time passed, the sound of Fatty Wei blowing water in the cabin gradually became quieter.
In the end, he actually stopped talking.
Li Zheng, who had been sitting by the bed reading, suddenly felt something was wrong. He looked at his watch and saw that it was already ten o'clock in the evening.
He turned to look towards Fatty Wei.
At this time, Fatty Wei was like an old monk in meditation, sitting by the bed without saying a word, his expression looking a little strange.
"Fat man, are you seasick?"
Li Zheng asked.
Fatty Wei grinned, with a slightly bitter look on his face: "Where did that come from? Is it possible?!"
"Is everything okay?"
"It's okay! I remember back then..."
Before he finished speaking, Fatty Wei suddenly spit out a mouthful. He quickly grabbed the plastic bag that had been prepared nearby, opened it, and spit into it twice more.
Wang Haiyang laughed loudly: "Fat man, we have just arrived at Xisha! Didn't you often fish in this area before? Why are you seasick?!"
Fatty Wei wiped his mouth, but he was still very stubborn: "I'm not seasick. I ate too much at night. Can't I just regurgitate the cud!?!"
Asking for a monthly ticket!
