Why amphibious vehicles can float in the water

Amphibious vehicles are equipped with the function of a boat, its body is designed to be sealed according to the buoyancy of the boat, and its rear is equipped with a screw propeller to play a role in propulsion in the water.

Who knows why, haha, it's easy to use, whatever, you don't have to make it

It is estimated that the space in the compartment is closed, and the sealing effect is better after the windows and doors are closed.

Because it's amphibious!!

1.The weight of the amphibious tank is several times better than that of the main battle tank, and the shape of the design is also convenient to float on the water, the chassis is wide, and it is also equipped with some equipment to assist in increasing buoyancy, because it is very light, so the protection is seriously insufficient, and it is estimated that 1 round of tungsten core armor-piercing bullet can directly penetrate the front armor (excluding ricochets).

2.It differs from the main battle tank on land in the following ways.

1): The combat mission is different, he is mainly used to suppress the beachhead and provide fire support for the beachhead landing force, so the power of the artillery is relatively guaranteed, and basically uses high-explosive shells and other destructive ammunition, after all, the armor-piercing ability of the 105 rifled gun is limited, so it is unlikely to carry more anti-tank shells.

2): The performance in all aspects is completely inferior to the main battle tank, as mentioned above, the amphibious tank because it can wade in the water, and it is a floating crossing, resulting in light weight, serious lack of protection, and can not install large-caliber artillery (the hull is light, the recoil of the large-caliber gun is large, and the installation space that is needed is large) causes him to fight on the road and almost can not engage the main battle tank head-on, moreover, the mobility of the amphibious tank that sacrifices the mobility on the road is not as good as the main battle tank (because the greater the power of the engine, the greater the weight, The engine of an amphibious tank is lighter, because he is also lighter)

3): The simplest, and most obvious difference, amphibious tanks can carry out floating crossings in deep waters, that is, water operations through thrusters, and tanks on the road can only carry wading equipment for "diving" and some tanks cannot dive crossing. Only wading through the equipment is a few meters deep

1.Amphibious tanks are very lightweight, so they can float, which is why amphibious tanks are super bad in defense.

2.In order to be able to float, the amphibious tank is very light, and at the same time, it is necessary to install water propulsion, which leads to low conventional combat capabilities, and is not at all an opponent of ordinary tanks.

1 Its cabin is airtight and not large.

2 It can be driven in shallow water.

1. The principle is referred to the ship.

2, the difference is that he can go into the water.

An amphibious tank has a propeller thruster behind it, and when it floats on water, it paddles forward.

The amphibious armored vehicle has good sealing, and it can float on the water like a boat, as for why he floats on the water and does not sink, it is recommended to refer to the Archimedes principle amphibious tank for landing operations and seize the beachhead, the protection is not as strong as the main battle tank, but the firepower is fierce.

There are two kinds of pushing: one tracked stroke and two tanks with thrusters in the tail are usually two

Take our 63A as an example, there are two thrusters in the back, and there is a pontoon tank in front of the waveplate.

1) The empty pin pressure of the branch on the horizontal ground is f=g=mg=22 103kg 10n kg=

The contact area between the n tank and the horizontal ground is s=2 2m24m2 The pressure of the tank on the horizontal ground is p=fs

n4mpa；2) When the tank is sailing on water, it floats, and the buoyancy experienced by the tank is F floating.

g=mg=22×103

kg×10n/kg=

n The volume of boiling water discharged by the tank is V row. F floats.

22m3A:

1) The pressure of the tank on the horizontal ground is.

pa；2) The volume of the tank to drain the boiled water is 22m3

1) The pressure of the tank on the level ground:

T Tank Journey:

s=vt=54km/h×

Answer: (1) When it stops on the horizontal ground, its pressure on the ground is n; 2) When it stops on a level ground, its pressure on the ground is Pa; 3) If the tank travels 30min at maximum speed on land, the distance traveled is 27km
