Why do you think there is a door at the bottom of the tank?

The tank consists of a tank system, a tank power plant, a tank protection system, a tank communication equipment, a tank electrical equipment and other special equipment and devices.

Overall structure. A tank is a complex fighting machine. Its wheelhouse is located in the front, the combat part is in the middle, and the turret is located here.

There was an artillery gun on the turret, and an anti-aircraft machine gun was installed. The rear of the tank had an engine. There are usually four people in the tank, including the driver, the commander, the gun commander and the loader.

Modern tanks are mostly a combination of a traditional hull with a single rotating turret. According to the installation position of the main components, it is usually divided into four parts: control, combat, power-transmission and action.

The control part (cab) is usually located in the front of the tank, which has a control mechanism, a detection instrument, a driver's seat, etc.; The combat part (fighting compartment) is located in the middle of the tank, generally including the turret, the turret seat and the interior space below it, which contains the tank **, fire control system, communication equipment, three-defense device, fire extinguishing and explosion suppression device and crew seat, and the turret is equipped with an anti-aircraft machine gun, a projectile smoke screen device, etc.; The power transmission part (power room) is usually located at the rear of the tank, which contains the engine and its auxiliary systems, transmission devices and their control mechanisms, intake and exhaust shutters, etc.; The action part is located under the wings on both sides of the hull, and there are crawler propulsion devices and suspension devices, etc. <>

In terms of general arrangement, most tanks have a cab in the front, a fighting compartment in the center, a power-transmission compartment at the rear of the hull and a longitudinal engine position. Some tanks have the engine horizontally, while others have a power-transmission arrangement at the front of the hull.

Walk on tracks.

The tank was tracked. Why not use wheels? This is because the tank is heavy, and if you switch to wheels, then the contact area between the wheels and the ground will be small, and it is easy to get stuck in the field; The tank is mounted on tracks, the wheels roll in the tracks, and when it encounters sand, snow and mud, the wide tracks disperse the weight of the tank, and the wheels are as convenient as walking on the road.

Look at the road in a tank.

When the tank is fighting, the window cover must be closed tightly. The people inside carry out combat missions, all by periscopes. (However, there are still some commanders poking their heads out of the turret to observe.)

The periscope can rotate, quadrilocate, and magnify objects like a telescope. The gunner also had a special sight to ensure the accuracy of the shelling. The tank is equipped with night vision devices, which allow it to see targets clearly in the dark.

The transmission device mostly adopts the dual-power flow fluid planetary type of electro-hydraulic control and hydrostatic steering, which integrates the hydrodynamic torque converter, planetary gearbox, hydrostatic or hydrostatic steering mechanism, deceleration brake and other components into one, a door at the bottom of the tank.

When the tank fights, all doors and windows must be closed tightly. However, once the tank was hit and caught fire, the people inside had to be quickly withdrawn. If you climb out of the top, you can easily be hit by enemy guns, so an escape door is set up at the bottom of the tank, and once the tank is hit and catches fire, the crew can quickly escape from the bottom of the tank.

** Several machine guns and high-pressure smoothbore guns of 120 mm or 125 mm caliber are used.

Because the tank is likely to be hit by the opponent's artillery in the process of the war with its Lujin tank, so there is a phenomenon of fire, at this time the personnel in the tank need to climb out of the tank, if it appears from the top, then it is very likely to be discovered by others, so it will be injured by the enemy's guns, so if you open a door at the bottom of the tank, you can escape well, and at the same time protect our lives.

For escape, this door is generally not easily opened, unless there is danger inside the tank, people will go out of this door.

This door is used to escape, and if the tank catches fire during the battle, the fighters inside can also escape through this door.

Because it can lead to fire in war, doing so guarantees the safety of tank crews and allows for faster escape.

1. To escape.

2. There is a "safety door" at the bottom of the tank, because the tank may be hit and caught fire in battle, and the personnel in the tank will climb out of the tank. And if you come out from the top, you can easily be injured by the enemy's wide guns. Therefore, opening a door at the bottom of the tank can increase the chances of escape and protect the life of the tank crew.

3. The tank is mainly composed of a first-class system, a fire control system, a power system, a communication system, an armored vehicle body and other systems, and is generally equipped with a Sun Yinliang large-caliber gun (depending on the type of tank, the artillery of some modern tanks can even fire anti-tank missiles) and several anti-aircraft or coaxial machine guns. Most of them use rotating turrets, but a few use stationary guns.

This door is actually for us to enter, and it can also be used for the people inside to sneak out and escape.

It may belong to a safe passage in the tank, and it comes out at the bottom to prevent accidents in war.

Because the tank is relatively tall, it is easy to enter if there is a door underneath.

There is a door at the bottom of the tank so that the person who drives the tank can escape.

Tanks are still an important assault weapon for future ground operations, and many countries are actively taking advantage of the latest achievements to develop new main battle tanks for use at the beginning of the 21 st century in accordance with their own operational ideas. The overall structure of the tank may have breakthrough changes, such as the appearance of external artillery type, unmanned turret type and other layout forms. There is a trend of further increasing the caliber of artillery, and the fire control system will be more advanced and perfect; The power density of the power transmission will be further improved; Various active and passive protection technologies, photoelectric countermeasure technologies, and automatic battlefield information management technologies will be gradually popularized and applied in tanks.

In the process of research and development, countries attach great importance to the unmanned tank, reduce the weight, reduce the size of the body, and control the increase in costs. It can be expected that the destructive power, survivability, and adaptability of the new main battle tank will be greatly improved. At the same time, this is the future direction of the tank.

The total combat weight of the main battle tank is generally 40 tons to 70 tons, and the weight of the main battle tanks of various countries has been soaring rapidly since the 80s. The caliber of artillery is mostly more than 105 mm, and typical models such as the T-72 of the former Soviet Union, the Leopard 2 of Germany, and the M1 Abrams of the United States. <>

A door is opened at the bottom of the tank to increase the chances of the tank crew escaping. During World War II, due to fierce fighting and technical reasons, tanks were hit and easy to catch fire, if the tank crew escaped from the top, or the upper sector could not be opened, a door at the bottom could help the tank crew escape.

The tank has more than one entrance and exit, the roof exit, the front armor top exit, and the tail exit, each of which has a different function, and the roof exit is generally for the commander, which is also the main observation port of the tank, and it is generally equipped with a gun mirror, and the front top exit is for the driver to enter and exit, which is more convenient, and the tail exit is generally very large, and it is generally used for escape and ammunition replenishment, as for the tank door you said, the door is open outward, so that when the tank crew comes out, there will be a bunker to dodge the Russian roof machine gun Generally, it can also be used with infantry, and at this time, it can also be used as a bulletproof shield when the roof section of the vehicle is opened.

An escape door at the bottom of the tank! It is a measure to ensure that the tank crew can escape if the tank is damaged! But it will lead to poor ballistic resistance at the bottom of the tank!

Encounter the drop of anti-tank mine protection! Even simple ** objects can blow up a tank with a bottom escape door! Some countries design tanks without a bottom escape door, anyway, each has its own advantages and disadvantages, and there is a wood with a bottom escape door to see the requirements of this country!

It is to ensure the safety of the tank crew's life as much as possible! Or make sure that the vehicle can be more resistant to beating!
