What are the benefits of a large buoyancy in submarine reserves?

It can increase the buoyancy of the reserve and improve the anti-sinking resistance.

Like the Soviet Russian nuclear submarine after World War II, its design is all double-hull structure. This design is not only robust, but also has a high reserve buoyancy (generally the reserve buoyancy can reach more than 30 percent), which can ensure that the submarine will not sink even if there is a large amount of water inside.

On the contrary, all nuclear submarines currently in service in the US Navy have a single-hull design. Therefore, the loss resistance is poor, and the reserve buoyancy is low (generally only 13%).

Of course, there are pros and cons to single or double hull designs, but in general, the latter is better.

The vast majority of submarines equipped by our navy, whether conventional or nuclear-powered, are designed with a double hull.

Good anti-sinking properties. Good surface seaworthiness (the freeboard of the submarine with large buoyancy in the reserve is higher, and the seakeeping and upwave resistance are better).

Improved unsinkability on water.

When the buoyancy is equal to 0, the submarine loses human control and falls into the deep sea self-sinking bird.

The density of the sea water is not the same, when the submarine encounters the undercurrent, the density of the sea water may not be the same, there is a possibility of sinking into the bottom of the sea, at this time, it needs to be able to float quickly, and there is also for the combat damage protection, when the submarine is damaged and enters the water, it is too late to pump water or cannot pump water, otherwise the submarine will really be finished.

Summary. Floating on a submarine to increase its own gravitational buoyancy will have many benefits. First of all, increasing its own gravity buoyancy can improve the maneuverability of the submarine, so that it can better cope with changes in various underwater environments, so as to better complete the task.

Secondly, increasing its own gravity buoyancy can reduce the submarine's crosswind resistance, making it better able to adapt to different underwater environments, and it can also reduce the energy consumption of the submarine, thereby reducing operating costs. In addition, increasing its own gravitational buoyancy also improves the safety of the submarine, allowing it to quickly return to the surface in the event of a dangerous situation.

Its bridge is completed, and the increase in the number of brigades and its own gravity buoyancy can reduce the crosswind resistance of the submarine, so that it can better adapt to different underwater environments, and can also reduce the energy consumption of the submarine, thereby reducing the operating cost.

What happens if a submarine floating on the surface increases gravitational buoyancy.

If the gravity increases, it sinks, and if the buoyancy increases, it rises.

I don't understand your question pro.

As gravity increases, the volume of water discharged increases, and whether the buoyancy becomes larger or smaller.

All right. At the same time, does it increase gravitational buoyancy, how much does it increase, and the tax increases a little more.

Grow bigger pro. That is, as gravity increases, so does buoyancy.

Yes, pro'', so it's still balanced by force.

Because there are water tanks on both sides of the covered submarine. The submarine descends when filled with water; The submarine rises when discharging. Compressed air is used for drainage.

People have successfully built submarines according to the principle of sinking and floating, and this kind of ships that can fight underwater have shown their combat effectiveness in previous naval battles, can dive to a depth of 500 meters from the surface, have good concealment and endurance, can attack surface ships and shore targets from underwater, and can also be used for reconnaissance, minelaying and transportation. <

Hyundai has also used nuclear power as propulsion power to make nuclear submarines, with a displacement of more than 10,000 tons in water, an underwater endurance of 200,000 nautical miles, and a self-sustaining capacity of 2 3 months. From primitive submarines to modern nuclear submarines, the principle of sinking and floating is the basis. However, long before the advent of humans, many aquatic animals already had good diving skills and had impressive pontoon system structures.

The submarine is achieved by changing the submarine's own weight. Submarine: It has several water tanks. When the submarine is about to dive, it fills the reservoir with water, so that the weight of the submarine increases beyond its displacement, and the submarine dives.

Force analysis of objects in the sinking and floating processes of liquids. Everyone knows that a submarine is a military ship, which can sail underwater to conduct reconnaissance and raids. But as for the working principle of the submarine, many students are not clear, and some even mistakenly think:

Submersibles sink when they are submerged; until it sinks to the bottom. In fact, after the submarine is submerged in water, the volume of the discharged water does not change, and the buoyancy it receives remains unchanged, and the control of its diving depth is achieved by changing the amount of water in the water tank (that is, changing gravity). When the amount of water in the tank remains constant, the submarine is suspended at a certain depth under the water instead of sinking to the bottom.

How can G change in suspension? It changes g only when it wants to rise or fall, and it does not change when suspended at a certain depth.

If it is rising or falling, then this state is called rising or falling, not levitating, only the state of staying unchanged at a certain depth is called levitation!

As long as g decreases by a very small point, it will rise all the way to the surface of the water; In the same way, if g is increased by a very small amount, it will sink to the bottom of the sea. If it does not want to rise before it reaches the surface of the water, it must increase g so that g=f is realized again, and it will be suspended at a higher altitude than before; If it does not want to sink again before it has sunk to the bottom of the sea, it must reduce g so that g=f is re-realized, and it is suspended at a deeper depth than it was. Got it?

After the change of g, the buoyancy will not be the same, the submarine relies on changing its own gravity to achieve the operation of diving and ascending, and obtains the upward and downward forces by causing the difference between gravity and buoyancy.

G can only rise when it becomes smaller, and G can sink when it becomes larger, in fact, G is changed by removing the water in the warehouse.

It can also float up, because the floating or sinking situation of the submarine is determined according to the space of the submarine compartment inside, when the submarine is going to sink, it will inject water into the submarine compartment, so that the submarine's own gravity increases, so as to achieve the purpose of sinking, if it wants to float, the water in the submarine compartment is released, so that the gravity of the submarine is reduced, and the submarine will float.

Yes, the submarine can drain the water inside, causing the total density of the submarine to decrease, and when the total density is small, it can float.

Of course, you can also use external force to push the submarine up.

To give you a very simple example, if you fill a drink bottle with water and put it in a fish tank, do you sink it? Hehe.

If this is usually empty, it is floating on the surface of the fish tank. If the bottle is filled with more than half of the water, the bottle is floating in the middle of the water in the fish tank.

This is the principle of submarines, submarines have many water tanks, and when they are underwater, they are filled with water, and then the water is discharged and floats up.

Yes, otherwise it would not be a submarine, it would be a sinking boat.

The buoyancy of the submarine in the water is only proportional to the volume, so when the submarine is completely submerged in the water, the buoyancy is always unchanged, the submarine discharges and fills water through its ballast water tank, and constantly changes its own weight, that is, the gravity can be changed, then the net force of the submarine in the vertical direction is constantly changing, so that it dives or rises, in addition, the submarine itself has a propulsion system, and the motion state of the submarine can be adjusted at the same time.

In addition, you say pressure, all the seawater pressure of the submarine in the water, only proportional to the depth, the greater the depth, the greater the pressure, this is the formula in middle school physics, your question seems to be that the submarine and the seabed are completely attached, this reality does not exist, first of all, the lower part of the submarine can not be flat, the cross-section of the submarine hull is mostly circular, and the seabed is mostly concave and convex rocks and sand, and it is impossible to completely stick to the submarine.

For an object placed in water, the amount of buoyancy it experiences is equal to the weight of the amount of water it displaces. If the weight of the discharged water is greater than the weight of the object itself, the object will float on the surface of the water, and we call it positive buoyancy. Otherwise, it sinks, which is called negative buoyancy.

If the weight of the water discharged by the object is equal to the weight of the object itself, the object will be suspended in the water and will reach neutral buoyancy.

When diving, it is very important to learn how much buoyancy is controlled on the surface and underwater. For example, when resting on the surface, positive buoyancy saves energy, while when underwater, you need to maintain neutral buoyancy most of the time to allow you to swim freely and easily in the water, maintain good visibility, and avoid harming you and the fragile creatures in the water.

The diver can adjust the amount of buoyancy by counterweights, buoyancy adjustment devices (BC), and the depth of breathing.

In addition, if you need to participate in diving activities, I recommend that you sign up for a sports trip, which is super cost-effective.
