The more he thought about it, the more excited he became, Li You couldn't help but take out his mobile phone and didn't start to check the information of the T-72 main battle tank, after all, these 100 tanks will belong to him in the future. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ。

T-72 main battle tank, the tank is armed with a side-by-side mounted 7.62 mm ПКТ machine gun with 250 rounds to be fired. The commander's conning tower is equipped with a newly designed HCBT 12.7 mm machine gun, which can only be operated by the commander with the upper body exposed to the turret, and has a maximum aiming distance of 2000 meters for ground targets and 1500 meters for air fire. 1 Type 2A46 125mm smoothbore tank gun with a short recoil distance, the barrel length is 48 times longer than the caliber.

It is composed of body tube, gun tail, cradle, stationing and retreating machine, re-entry machine, thermal sheath and smoke extraction device. The gun pitch angle relative to the turret is -4.5°-14.5°, and since the turret seat is tilted forward by 1.5°, the actual pitch angle of the gun is -6°-13° when the gun is forward, and -3°-16° when the gun is backward. The thermal sheath was made of light alloy sheet with a total of 4 sections, and the extraction device was in the middle of the barrel in the position of the muzzle. This gun was also mounted on other Soviet tanks such as the T-64 and T-80.

ammunition

The 125-mm smoothbore gun fires three types of shells: БР11 or БМ12 tail stabilized armor-piercing shells (APFSDS), ЗБК14М tail stabilized armor-piercing shells (HEAT) and ОФ19 tail stabilized grenades. The maximum effective range of armor-piercing projectiles is 2120 meters, the muzzle velocity is 1800 m / s, and the armor-piercing thickness of the two armor-piercing shells at a distance of 1000 meters is 300 mm and 400 mm, respectively; The muzzle velocity of the armor-piercing projectile is 900 m/s, the maximum direct firing distance is 4000 meters, and the armor-piercing thickness at a distance of 1000 meters is 475 mm; The muzzle velocity of the grenade is 840 m / s, and the maximum effective range is 9400 m. Although the 2A46 series can fire wing-stabilized armor-piercing shells at a high muzzle velocity of about 1,800 m/s, it is not yet able to effectively penetrate the frontal armor of Western tanks such as the Leopard 2, Challenger 1 and M1A1 at a distance of 2,000 meters. The tank carries 39 shells, the ratio of which is generally 12 tail stabilized armor-piercing shells, 21 tail stabilized grenades and 6 tail stabilized armor-piercing shells. Semi-combustible cartridges were used for split shells; 22 shells are stored in the rotary ammunition conveyor of the automatic loader, the upper layer is a cartridge, and the lower layer is a projectile; The middle group of shells behind the gun basket of the turret stored 9 shells; 4 shells are stored in the small compartment to the driver's right in the front of the hull, 3 shells are placed vertically and 1 shell is placed horizontally on the rotating floor...

"Damn, this tank is too old, it's just an antique." After reading the information, Li You was speechless, just this thing, it's too old, not to mention the 99 type, even 96 is stronger than it. But when I thought that I was going to take back Datang to use, I was excited again and took it to Datang, not to mention this T-72 main battle tank, even the 38 cover is also an existence against the sky.

But what Li You didn't know was that the T-72, like the T-64 and T-80, used an automatic loader to load shells, and its magazine was set in a rotating disc under the turret, which could be loaded with 22 shells. The detached shells in the magazine are placed horizontally above and below, with the propellant on top and the warhead below. When loading, the shell carrier rises to the height of the tail ring of the gun, first reloads the warhead, then lowers the charge to reload. After firing, the remaining metal shells are withdrawn from the breech and caught by the ejector at the rear, and then thrown out of the car through the opening at the rear of the turret.

The reloading process takes an average of 6.5-7 seconds to complete, but it can take up to 15 seconds to reload because the carousel can only rotate in one direction. This allows the T-72 to reach a rate of fire of about 6-8 rounds per minute, but in the event of a failure of the main gun hydraulics or a failure of the autoloader, the reloading time will increase considerably. In addition to being able to load long shells and rotate in both directions, the new automatic loader installed on the T-90 and other new T-72s in 2006 also has a continuous reloading mode: the automatic loader reloads itself after the main gun has been fired. These improvements have resulted in a shorter reloading procedure for the Autoloader, which can fire three shells in a row in 13 seconds, with an average of 4.3 seconds per shot. Therefore, the automatic loader on the Type 99 main battle tank that he mentioned was copied from this.

Thinking of this, Li You couldn't wait, and the next moment, his figure disappeared into the room.

"Hiss~ I wiped it, it's too cold~" Li You couldn't help but shiver when he was frozen.

Since the assembly place of this batch of tanks is located in the plateau area at an altitude of 4,500 meters, not to mention the thin air, the temperature is now reaching minus 45 degrees Celsius. In this kind of weather, it can be said that if you accidentally touch the metal, it can cause frostbite.

"Paralyzed, Xiao Ah San, what do you say you are doing with some iron shells, just this damn weather, the tank is basically a waste when it comes here."

Li You is really right, the daily maintenance work of this Ah San tank is indeed extremely difficult. In this weather, the normal operation of the tank has been seriously affected, and it needs to be barely maintained with special lubricants and fuels. The living conditions of the soldiers stationed there were difficult and dangerous: not only did they suffer from the cold, but because of the altitude they had, it was difficult to breathe...

"Hehe, hey, no, this little Ah San is here to send it to my brother."

Li You picked up the satellite map sent by his grandfather to him and quickly found the location of the tank, this is a very open plain, looking at the tank regiment faintly more than ten miles away, Li You began to make trouble, there is a whole tank regiment here, so the number of people is no less than 3,000 people. How can this begin?,And,I'm afraid I can't get close to here now.。。

But this seems to be really difficult for our eldest son Li, and the next moment, Li You appeared in the sky above the 10,000-meter altitude of the original place. Speaking of Li You's coordinates, there is no distinction between the sky and the ground.

However, at this time, Li You is falling in a free-fall position.

"the groove~~~" Li You just opened his mouth and wanted to scold, but his mouth was directly blown by the wind and opened wide, this is 10,000 meters in the air, not to mention the temperature, plus Li You has not brought a mask, so it is very difficult to breathe, this time Li You almost fell into a coma due to lack of oxygen, and endured the pain, Li You hurriedly returned to the Pixiu space.

Lying on the chaotic ground of the Pixiu space, Li You began to gasp for breath. After relieving for a while, Li You eased up, and his body was no longer cold, and he rubbed his cheeks that were still sore from the wind, "Paralysed for a few old antique tanks, buddy almost didn't take his life~ Alas! This is not something that people can bear, what can be done! ”。。
